AC Compressor Overheated Not Cooling Testing Windings/ Megging, Ohms Fixing HVAC System

- The ac service call in this video is on first hot 90 degree weekend of the season. On call emergency service is different than standard service calls. The objective is do whatever can be done to make system work. On service call and I run into a compressor that has overheated. I checked the windings and find at the windings are opened. Therefore I have to cool off the compressor. After cooling off the compressor I mag out the compressor windings to verify the insulation is still good. Furthermore a check and verify that the compressor has closed its overloads and I have continuity and ohms on each winding.
Now that I’ve verified the compressor windings insulation is good. I start up the unit and find the system refrigerant charge is low on r-22. Not enough refrigerant returning to the compressor has cause it to overheat.
I let the homeowner know it is time to replace the system. They want me to recharge the system at first using only 3 pounds of our 22 since it’s expensive. I told him they were going to have to pay me what are the 3 pounds would fix their system or not. After putting 3 pounds of our 22 into the system, the pressure still we’re low. The homeowner told me to put another pound. Afterwards one more until the system was correctly charged. I put 5 pounds in and I charge the system back into operating correctly. The homeowners know they need to replace the system. Since R-22 no longer is in production. Yet with temps above 90 they just wanted relief from the heat.
What a hack..... no Freon and without even looking for the leak he fills it with Freon. This guy has a lot of tools and no idea how to use them. I might have got a good charge... without pulling a vacuum or looking for a leak before just filling it with Freon I highly doubt it will last a week. Terrible service technician patting himself on the back for helping destroying the ozone layer. Way to go
I love when snowflakes try to talk shit. All a snowflake like you Michael does is show your ignorance and lack of knowledge. I been fixing hvac systems to code and doing what’s best for my customers for 22 years. I already know where the leak was. It was found in 2019. This system cooled this house until it was replaced just this week. I know how to use my tools. You must not be an HVAC tech. You don’t pull a vacuum on a leaking system. Tell me how deep your getting that refrigerant circuit to pull down. Why would not pulling a vac prevent this system from lasting a week? This system was never exposed to moisture or contaminants. Standing pressure was 120psi. This was a small leak. Many years back this was a common repair. A terrible service technician would not provide temporary comfort for their customer. Until the system was replaced.
@@thehvachacker as soon as he said Freon you should have just laughed him off 😂 micheal Keller what certs do you have to back up your agreement
I was thinking same, I taught he was going to look for the leak.
@@towu4less126 not in this situation. Use your brain
We all watch these 10 min videos, not even getting a 1/4 of what the whole story is and snowflakes like this assume anything that isn’t said in the video. Dude go back to a Biden rally and stay away from this channel if you don’t like it.
i saw some comments and im an industrial fitter, instrument tech, control tech and plc programmer.... its easy to say oh in school blah blah blah.... that's in a perfect world where everyone is rich and has unlimited income. in the real world, where you have to work with people who dont have a couple grand sitting around, you have to get em going cause its 120 degrees outside they have kids and grandma has dementia and thinks the heat is jesus . sometimes the best fix isnt the ideal fix.
So true man so true. Sometimes cheap and easy is the best for everyone involved, unless of course ur dealing with someone that can afford a new unit and they tell u money isn't a problem go ahead and fix it.
Keep doing what you doing brotha! Just another day in the field.
What you did in the video was absolutely reasonable. A gas and go until a system change out can be done is perfectly reasonable . Ignore those people typing on there keyboard with nothing better to do.
I don’t think many with the negative comments are crying about the ozone ever did HVAC on call service work on first hot weekend of year. They can complain and I will just providing comfort the best I can for my customers
I read some of these comments and I did not see anyone mentioning the recovering of R22 and doing a nitrogen test with some trace of the R22 left in the system to pinpoint the leaks . Even if a pump down was done first you could check the evaporator side and lineset before recovering and repairing or selling a new unit. I'm new so please give me a knowledgeable answer. Thanks
The youtube trained HVAC techs are up in arms, lol.
Good job this unit looks had a bad installation or it is old to leak check it they have to change leak check it and fixi what is leak came from depents on customer budget you are right good job
I like the way they talk, like we all do that crap everyday. Houston we have a problem. 😅
After watching this video I just wish I didn't cause I am totally stoned now and I haven't even lit my lettuce yet😎
Awesome job saving that old Lennox. Personally I'd rather put $900 towards a new system and replace it, but it's their money. Great video
They will still replace it. The inevitable is them needing 22 and no more around. I don’t play with drop in so then no ac till it’s replaced
@Shawn Gipperich we all do different approaches. Yet the inevitable is the older r22 machines will need to eventually be replaced. This machine is getting replaced this was only to keep it running until then. Which is mid June. Many say this is a big leak. Yet took 2 years for the refrigerant added last time to leak out.
Was there standing pressure or did you charge it while absolutely empty? I’m assuming because your superheat checked out that there was. I must’ve missed that part in the video.
Great little vid Hackster ... much appreciated ..👍👍👍
I have that same old megger on my van right now. It's my back up. My Fieldpiece is my go-to.
I was considering the Fieldpiece or fluke. Yet most the fluke models are 600+.
@@thehvachacker yeah the fieldpiece is a great option. It's just around $100 range. Nice and small and compact. And actually gives you a numbered reading on the screen.
@@thehvachacker mine is the old version back when they used to be Gray, before they change to the yellow color. I've had mine for about 17 years now.
Damn bro, I feel bad for you getting trolled by all these youtube HVAC "experts" who obviously havn't spent any time in the field.
As a tech with 22 years of experience in AC/Heating/Refrigeration/Controls/ and even Air Balancing...in residential, commercial, and industrial...
My opinion is that this was a good (and typical) service call.
And for the record:
1. A leak search, and/or repair (if possible) on this unit is pointless and a waste of customers money due to its age and refrigerant type.
2. You informed them of the situation and thier options and let them choose what to do.
3. Completely understandable why you "technically" left it just a lil undercharged. Considering you just went back to them twice to get the ok for another lb of r22. And now up to 5 lbs.
Especially because it needed, and got, replacement anyways. Its got a 20 degree split.
The only thing I would add, which u probably know, if you ohm out the windings, if you get continuity across R and S, but not R and C, or S and C....
Then the overload is open. This is because the overload is located on the common wire.
In 22 years you've never heard of EzSeal? In 22 years you've never advised a customer it's pointless to charge a system with that much discontinued refrigerant without some sort of repair attempt even if it's just sealant? This video was a shit show and you know it.
@@chicagomodzz But he informed the customer of thier options. They chose to get the AC going with new refrigerant then replace the system a few weeks later.
Why is that wrong to you?
We are here to provide comfort to those who want it. Doing the cheapest thing is not always the best thing.
Its best to give the customer the info and let them decide thats how u keep customers.
Leak sealer? Maybe if it were 10 years old. But on an old R22 unit with visibly corroded coils? And at the end of its lifespan? No.
Lets say you sell them the leak sealer, which we know isnt guaranteed to work. Maybe 50/50 chance.
If 3 weeks later its empty again, and they are in the same boat, (if they even call you back) now they need another charge to get AC that day in the heat wave, and STILL need to replace.
That makes you look really BAD. You cost them alot of $. Thats how you lose customers.
And dont forget its old as hell. What if the fan goes, or compressor goes? Whichbit inevitably will.
Dumping money into a unit that needs to get swapped anyways.
You need to look at Total Cost of Ownership of a system.
Its better to skip the part where you spend a bunch of money on a unit at end of life, and instead replace sooner than later.
He topped them off with freon, then had the unit replaced a couple weeks later. It was the right call for the customer.
I would have advised them that r22 is expensive and if we are swapping the ststem, it would be wasted. Its thier call if they want to do that. In this case they did.
However, I would have offered them the 1 ton portable i carry on my truck. And a couple others we have at the shop (If they sign a contract for replacement today😁)
But if his company doesnt have that capability 🤷♂️. Well then you offer the options you have.
What is wrong you? Compressor is overheated and the fan shows signs of life but you’re not concerned with what else could be wrong? Checking to see if it has charge should be basic before taking everything apart. Compressors overheat all the time due to under and overcharge. Basic systems don’t have low pressure switches and you can clearly see this unit is no different. Of course it would be overheating. Adding any refrigerant to a flat system is never recommended. Even if it was 410a… pressuring the line set and doing a leak search would be good practice. Secondly… if no leaks are present and pressure holds changing the drier and pulling a vacuum would be the next ideal repair. (Assuming Pressure is applied through the high side and into the low side to check restrictions, good purge.) Finally, checking the system under load with virgin or recycled R-22 if that’s what is decided on over replacement.
Mario you want my customer to dump a lot of money into a system they want to replace. Evaporator was found leaking 2 years ago last time we charged this system with about the same amount of refrigerant. I have a compressor with open windings. First priority is seeing if I can close the windings. I could close windings the. Start system which wasn’t flat or it would of pulled into a low vacuum. I started this system with a soak and wet condenser, I hosed it out while cooling compressor. Customer wanted to get this system running for temporary relief until they get a new system. I don’t sell my customers snake oil so no stop leak. I don’t believe in wasting my customers money and providing comfort is the business I am in. If I don’t someone else will. We don’t have customers shopping around. I also am on call, first hot weekend. Means calls are comment in 2 or 3 at a time.
@@thehvachacker that’s good. A little history goes a long way. Maybe I missed the backstory considering what was going on with the video. As long as the client has been given options and you have done everything you can in the mean time for temporary cooling. That’s all we can do. This video may have been for “Educational” purposes but it often leads to bad practices that should not be followed. I would emphasize that you have done all you can for the client before “patching” this unit for a quick fix. Everyone here wants to quickly call out your mistakes but they fail point out what good practices should be taken. Thank you for replying to my comment.
Good job Bill, you saved it! Who knows how long it will last.
It’s getting replaced in June. This was just to get them by
Had a coworker looking at my mega ohm meter. One of the leads was touching his arm and he pressed the button. I got a laugh and a new meter
Good laugh new meter sounds like a good time. It’s only 500 volts with no amps
I have fan 5sme39hl hf056 that got really wet and not running any more. Is there an easy replacement for that or do i need exact same motor? Thank you
What is the typical operating temperature of a common kitchen refrigerator compressor? A modern one, less than 10 years of age.
Mine is running 125F when not running, and up to 170F when running a lot to restore fridge and freezer temps. Is this fine?
Thanks.
Great video amigo thanks 🙏 alot for your time
Good video! Apologies for the "Keyboard Supertechs" who judge your work when they weren't there and didn't talk to the customer. Side note: I have the same scale. I know there are newer fancier ones, and its probably the oldest piece of equipment I own, but the resolution is SO much higher than most scales and I charge alot of critical charge systems. So if I need 4.6 oz, I don't wanna guess when my scale only goes from 4.5 to 5.0. I LOVE that it goes in 0.1 oz increments. And in grams its 2 gram increments. Add to that the fact that its indestructible, and its a winner! Keep doing what you do!!
It’s a great scale I wish the latches on the case were built as strong as the scale. Yet I see no reason to get a new scale. I haven’t shopped around. This scale is about 12 years old. Shame if most new scales don’t give as precise measurements. I know I have fancy gauges yet the Fieldpiece probes were referred to me by many of my subscribers. My only complaint on this scale is no auto off.
I know this is not a window unit your working on, but I am puzzled with this LG window unit AC I am trying to fix. The compressor is coming on but it takes a bit to finally kick on, and getting cool normally for a few minutes, but then it starts getting hot and the compressor only is shutting off prematurely and then about 6 to 10 minutes later it will kick back on and blow cold again for a few minutes and then the same issue repeats? Do you think it needs freon or a electrical part, or do you think the compressor is bad? It does vibrate alot and gets louder when it starts getting hot. I have the cover off and it's not all clogged with debris/dust, and the fan works fine. It's a 9,800 B.T.U. Unit and it uses R410A refrigerate. What do you think? Thanks
Not a technician, but the system might be choked. The filter drier or the capillary bcoz d freon needs to pass through d compressor to cool it.
"She's a leaker mama... oh yeah... she's a leaker!"
Soon this leaker will become scrap metal
System with that low of charge has a leak. Why no leak check? It’ll be empty again sooner or later.
It’s getting replaced. No reason to waste customers money on a system that needs to be replaced. I told the customer that before charging. This is just to get them by until the new system is installed. Mid June is when it’s scheduled
@@thehvachacker perfect. Yea kinda pointless if it’s getting replaced in a couple weeks.
@@thehvachacker This one could have been saved. Find and fix the leak R22 is still around and will be for awhile plus the price is dropping. Could have retrofitted to a different refrigerant and save the customer a lot of money. I have worked on system's that are 30 to 35 year's old and still putting out.
I repair old units all the time. I don’t like sending a system to scrapyard. I also have many videos fixing old systems. Many comment that what I did won’t last. Many of those repairs still going many years after. This isn’t a fast leak. It’s a slow leak in an evap coil, document by a coworker on a previous leak search performed in 2019. The last time system need a few pounds. No reason to change an evap coil on r22 system.
@@thehvachacker hello,
What tools did you use to checking the pressure Sir and which app.
It seams pretty easy. The way you explained it vs my teacher doing it . Thanks
Does anyone know if there’s any benefit to spraying a compressor down when it’s running on really hot days? We had a string of 108-109 degree days in Texas recently, and I felt compelled to go out and water the compressor through the grill a few times during those days. Does doing that make it less likely to break down if it’s operational?
Not directly on the actual compressor, but a mist or sprinkler running on the condenser coil that surrounds the compressor on really hot days *can* really help out a struggling system, but it’s not something that should be done on a regular basis, as you risk excessive corrosion of the coils/tubing, which can lead you to a leak. If you’re gonna do it, save it for the hottest parts of the hottest days when your system is under its heaviest load.
Use - R-422B - it is perfect replacement for R-22 - the same pressure, the same oil .
He’s doing it slow. Hacks are 40 degrees and out. I like his slowness. Take him anyday
lol he left that system right on 32 degrees on the evaporator coil temperature, I wonder if he got it made home before that thing either froze up completely, or that r 22 leaked out to the point where it was in the beginning of his mission ))))
So you charged it but what caused it to lose the charge doesn’t make sense
Wonder if system low like that, do you think there maybe air trap inside?
Hard to tell. Yet I recommend replacing. They wanted temporary cooling. The system wasn’t running like it had noncondensible. Yet with a leak it needs to be replaced.
The compressor has an auto-shut-off fail safe mode if too low on juice? What's the cost of a new compressor?, Install in a day ?
No safety on this system for low pressure. Yet due to it being an old r22 machine it's getting replaced with a newer unit. I usually don't recommend replacement unless it's an old r22 leaker. Never if it's only an electric part. R-22 has been phased out
The great Hacker is always doing a great job !!
Good job man, just curious I know the system is old and its probably have holes in it since its 5lb gas. Just for confirmation, it had holes and they cant afford it or you couldn't check because they cant afford it?
It had 3lbs added in 2019. They had money, nice middle class neighborhood. I was jammed up Sunday call and worked to 1am that day. When I am on call/ emergency service, I don’t leak search often. Since it’s an emergency they are calling up about. I will do what I can to make their system work. Then usually a follow up for a leak search happens during regular business hours. If it’s a during the week service call then I will do a leak search. Yet with r22 it’s not really worth to fix leaks anymore.
@@thehvachacker Good job,dam 1am. Good information on r22.
@@thehvachacker American environment protection laws are kind of crappy, here you can't even charge an r410a system without finding and fixing the leak first. R22 is straight illegal if you need recover the remaining charge and use replacement gases or replace the unit if it leaks.
@@netpok we are allowed to recharge a system. No laws agaisnt. Yet how long will supply last. Plus that call was just under a grand. Not many times will many want to pay that much when zero warranty it will last a few days. If flat I won’t even offer to charge. R22 must be replaced and 410 leak search must be done. Yet system had 100 psi standing pressure and this is first hot week. I know it will last a month if not the whole summer.
@@thehvachacker Yeah, I didn't mean to say it's "your fault", if there is no law against it they will just call the next guy in the phonebook if you say no.
I find a lot of leaky schraders and when the cap o-ring finally rots through, there goes the entire charge in no time. Pretty sad, actually...
good working
Were you get that tool from? Amazing
I which tool? The refrigerant gauges?
Nice 👍 what happened to the refrigerant that was in there? Did you inhale it 😆
Good job
put bag of ice on top of compressor and let hose run on the bottom 👍👍
Ice works if you have it. a hose and running water will always cool the compressor off. That is always available. I can cool the compressor with running water faster than I can run out and buy ice. There is a hose adapter someone made for cooling compressors. who knows maybe one day I will buy it.
Im no expert. But if it took that much freon. There has to be a leak. Isnt r22 kinda expensive?
It has a leak on the evaporator coil. I sold a system while here get customer wanted temporary cooling. Until new system was installed.
Even if I'm in Vegas and 22 I'd rarely used anymore. Just ask the supply houses. MO99 and 422b (nu22) are the refrigerants of choice out here.
I love listening to guys still in school or guys working through there 1st-3rd summer tell people how bad of a job they're doing! It's soo easy to tell how long they've been in the field.
When its 110°f on the ground and that means it's 125°f+ on the roof & on top of that you've got 8 more calls to do before you get to go home, let's so you do every tiny little thing the book says to do. The customer doesn't care about any of that shit. They care about 1 thing and it's the same thing your boss cares about......***it's you selling a new unit or fixing that and getting them some cooling with a quickness so you can get your ass to the next one. Maybe it ain't as busy where y'all are but I know here in Vegas we can't see straight right now it's so busy.
I give the option to put uv dye with leak sealer and have had a lot of systems saved for years and if the sealer didn’t work u can find the leak from the dye it seals most of the time with r22 but rarely ever with r410a cuz the pressure is too high had a r22 losing 6 pounds every year and every tech tried selling them a new system but they cudnt afford it and now it’s sealed and they not paying $500 just for Freon every year
EzSeal+UV for the win. It's my go to on low R-22 systems. Since 2020 I tell customers it's basically a requirement at this point.
Yeah I give it a week before enough pisses out that they have no cooling again. If anything at least do EzSeal.
This system will run until it is replaced in June. For years systems have been charged back up with 5-7 lbs and ran the rest of summer if not 2 seasons. This system has been charged a few years back. Very small leak rate. Yet it is being replaced.
Did you find where the leak was? You completely filled the system, I did not see nor hear you mention finding a leak prior to addiing refrigerant?
This is not a standard service call. This is a Sunday emergency call on the first hot weekend. No leak searches are performed. Only repairs to get systems to operate and return on regular business hours for leak searches or big repairs. New system will be in mid June
@@thehvachacker You do realize the purpose of the Montreal Protocol Actt was to prevent hydrocarbons from destroying the ozone layer of our atmosphere. It just seems irresponsable to knowingly fill a system which had previously leaked out all its refrigerant, some six lbs of it. I think its a serviceman/womans job to prevent more freon escaping. I would of informed the customer that returning the following day to do a evacuation and a search for the leak was protocol. You would of gotten much better out of it. First you would of prevented more freon leaking to the atmosphere. You would have saved the owners the cost of additional freon in the future and would of fixed the leak. You would also have recieved a few extra hours of work by completing the job. Instead you will have to bill again the customer when the loss occurs poluting our atmosphere and putting the customer through another cooling related service call. I understand it was an emergency call to get them cool again but I can not stress the importance of fixing the leak the following day when normal hours resume. It will make you a better serviceman by doing so
@@jbpost52 yeah your right..
The follow up for this leaker was a sales lead. The customer already has paid for a new system. They just wanted cooling then and now. Their system will be replaced mid June. If I don’t charge the system up someone else will. 95%-98% of the system charge will be recovered.
@@thehvachacker If the customer is sceduled to have the AC replaced in mid June, it might be wise to push the scedule up to the following day, otherwise the freeon may leak faster than anticipated, provided your work scedule allows for advancing the time slot of this job. As you mentioned you already sold this job to be done mid june.
So many negative comments on this video. I agree that it is a lot of r22 but it is also very easy to armchair quarterback. You all have no idea what this guys schedule was like. How many calls he did before he got here and after he left. He also got the ok from the homeowner before proceeding.
This was a Sunday emergency service call. I worked from around 7am till past midnight. This was just a bandaid until system gets replaced. During the week scheduled service calls its easier to perform leak searches, and numerous other tests everyone is upset about. I doubt most know what a busy weekend on call with no backup is like.
With that large of a LEAK I beleave I would fix it or replace it and since it's R22 Replace It.
The unit was replaced not long after this call. This was to provide temporary AC until a new system could be replaced. The evaporator has a small leak. System last was charged up before this call 2 years earlier.
Wow, in the eu R22 is banned, also recharging a known leaking system can land you jail sentence and a massive fine,
Do the US not operate under kyoto protocol?
No laws against. All the r22 gas was recovered today when system was replaced. R22 will be around until all the cans are emptied out.
Are you new? Lolol.
Dude R-22 is still around. During the Obama Administration everyone scrambled to replace their R-22 equipment because of massive EPA overreach and massive amounts of R-22 was recovered and sent to reclamation facilities. Just because it's not being manufactured anymore doesn't mean it's no longer available. So many R-22 systems were replaced that the price of R-22 actually dropped at one point. What are you going to do when you put in a new R-410a machine with that logic and it is phased out a year later and you have to explain to the customer that they will need to replace their system again? You can literally still buy R-12 and it hasn't been manufactured since 1996. R-410a is literally on it's way out. Daikin has already committed to R-32 (you know, the parent company of Goodman). Did you even look for oil? The suction was in a vacuum so signs of oil should be present somewhere and, even if you don't immediately see any, a leak detector should pick up refrigerant somewhere. For all you know, the leak could be a flare nut on a TXV that just needs tightened. Also, why are you charging by vapor? Seems like a giant waste of time considering that after a pound or two the bottle gets so cold you can barely suck any vapor in. All blended refrigerants must be charged by liquid so why not charge by liquid for all refrigerants?
The worst thing about this entire video is that you walked away from a unit that literally just had a compressor out on thermal overload due to inadequate cooling because of low charge with only 2 degrees of subcooling on a unit with a TXV. You literally left the unit low on charge. The chances of having a solid column of liquid at the TXV are slim to none. What kind of service tech asks the customer how much refrigerant they want added? You either charge it properly or let a real professional charge it. Never in my career have I let a customer dictate how much refrigerant was added to a system. It's charged when it's charged. They know know up front how many pounds it holds and how much it costs per pound. I do it right or I don't do it at all. Of course I never ever ever troubleshoot a unit without inspecting the entire system to begin with and I NEVER neglect to look for oil when a suction is running in a vacuum. HVAC Hack is a more appropriate channel name. You just want to sell a new unit. I'm sure you had a nice long talk with them about that off camera.
If you are watching this video for educational purposes I highly recommend you choose a different channel. 0/10 for skill, 12/10 for half assed hackery.
Truth bomb
100% agree. Where was the check for a leak? Especially this expensive R22. It's just going to leak out again.
@@f.hababorbitz At the end of the day, a full blown leak search is the customer's choice but it only takes 15-20 minutes to visually inspect for oil and run a leak detector over U bends and common leak areas such as rusted filter driers and accumulators. I would have 100% charged it up, leaking or not, if that is what the customer wanted me to do. A happy customer is a returning customer. Customers will spend more for repairs/replacements if they feel like they are receiving quality service and aren't being screwed. It's hard to do that when the unit wasn't even charged properly to begin with and will most likely start flashing in the liquid line in a week or two and, subsequently, run with a starved evaporator and high suction temp (that's what causes compressors to cycle on overload after all) because it's still under charged.
Should of just taking opioids!
Bingo stockpile of r-22 years supply left . Markup is through the roof the industry did the same thing with r-12.Train has left the station with global warming . If they where so concerned about our earth why close all American coil factories that made quality coils that didn't leak .HO CHI MINH CAN POUND SAND!
Hacker is hacking Again !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Keep up the great vidjas !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
It was a long week last week. Only 80 hours
You are the man as always !!!
Why didn't you do a leak SEARCH?
Good afternoon sir, good work done.
please what is the name of this
tablet for checking everything on the system.
You meg the compressor without checking the freon? 😅
You said Freon 😂
No more repair on 22 it's done there at 1/3 of new equipment. It's not going hold long made this error a few time's
I’m not expecting this to last long. Told the customer there’s zero warranty if they want me to refill it. I told them they need a new unit, it’s inevitable.
That R-22 charge must have cost the cusomer a $500 dollar bill for the charge? Nice job charging it.
This bill was in the 900 range. Took some time to cool down that compressor
@@thehvachacker I have a neighbor that still has their original A/C systems from 1994. Although they have replaced major parts on them such as the evaporator coil and compressor (I think) to name a few. People who still have R-22 systems their days are numbered as soon as the system develops a leak; soon they will have no choice but to upgrade their A/C.

Incorrect.
He should've done a pressure test, located the leak, and then notified the customer.
I should not do a pressure test on a system that the customer wants to replace. The leak is somewhere on the evap coil. Was found in 2019. Customer wanted relief from heat. Also a new system. Rob you still in school learning? Real world service calls, dealing with other people’s money. Requires common sense, and respecting your customers.
@@moisty254 nope bud that’s not the way it works. It costs money to do a leak search and sometimes people don’t want to pay for that. That why ya give em the info, put the ball in their court and do what they want you too.

Wouldn't you first do a pressure test the moment you notice the gas isnt there?
Gas was in system 120psi until I started with wet coil pressure will always be lower until it dries. Yet not under 10
Why don't you test for Leakes before you put in the 5 pounds R22
Do you do a leak search on a system that should be replaced? That just runs up the customer bill. Also the evaporator was found to be leaking in 2019 last time we filled it up.
I check filter first . before charging
I checked filter it was ok. They have a maintenance coming up in 2 weeks and will get it changed then.
@Magesh Mahi yes. If low the refrigerant coming back in the suction line is too hot. The compressor relies on vapor refrigerant to cool it
xin chao moi người. from VietNam
Why wouldnt you go off the name plate for the charge?
Most units have a lot more refrigerant than the name plate. The name plate is only good if short line sets are used
Name plate weight is the condenser filled plus 15' of lineset (normally)
I would have found leak before adding refrigerant to see if it would be a simple fix if not customers just need to understand that an old worn-out unit is a old worn out unit not trying to sell them another unit it's just old and worn out
I set them up for buying a new unit. A leak was found in 2019 on evap coil. Customer wanted cooling now so I filled it. Next day a salesman from my company sold them a system. Looking for a leak on an r22 system usually will just waste a customers money. I will fill to temporary get a system running until a repair can take place. That’s how I operate. What most commenting here should read description of video. This call was on a Sunday. If you watch my videos I sealed many leaks. Yet on a Sunday I am not sealing anything. It’s emergency service. Therefore what do I need to do so customer can be comfortable. Then big repairs or leak searches get follow up visits. This is also first hot weekend. I finished the week low 80+ hours of work. Too many calls to waste time looking for a leak. My customers know it’s in their contact. Emergency calls are emergencies. No maintenances other than addressing what’s stopping system from running. During regular work if this was a 410a system I would leak search the system. Yet r22 systems are all on the older side now.
High velocity systems suck ass. You never get them dead on. Blower motor rpm is way faster than any other. You did what you had to do.
sounds to me the customer just wanted relief in some hot ass weather until they can get the new system.. So some people want bill to not only charge the labor to find the leak(s) but they also want him to fix the leak(s) which is another charge. on top of labor to run vacuum, and charge the system? Why invest even more money into a system that is outdated and costly vs getting by with a lesser bill and getting a more efficient system?
Me personally, id rather tough it out and put a new system in rather then spend 100$ per pound of r22... but that's just me.
R22 is so expensive right now. I would of pushed them for a new system.
I sold them a new system it went in 2 weeks ago. This was to provide temporary cooling
And THIS is the reason I keep avoiding people like you, always trying to upsell poor unsuspecting homeowners a new system who know no better. For 20 years, techs have come out for minor servicing of my two 1998 R22 Goodman units and all wanted to be THE ONE that sold me an entire new system. No thank you. Please just fix the issue I am hiring you for. These systems have replaceable parts like legos. Is R22 expensive? Sure. So give them guidance that they can replace it with cheaper MO-99 or R-422B. Don't be a shill for your company and try to slam them changing out the entire system (including indoor air handler, linesets, thermostat, probably duct work, etc) when all they really needed was a replacement part or to find the leaky schrader valve or whatever the issue is. Heck, even replacing the compressor (which I have had done) is FAR cheaper than changing out the entire system. It's just silly. These systems today are garbage. They should be built like tanks and last for decades with little to no service calls, like the ones from the 70s and 80s. But now, every tech that comes out complains that the latest systems are SO delicate and problematic. They love how simple these older systems were.
hot compressor, spray it with liquid nitrogen, CO2 or refrigerant(LOL). that's what they did years ago ;)
When I started ac work a guy I worked with was killing bees with liquid 22. He was good freezing them up midflight
@@thehvachacker yeah that also!
chlorinated "brake parts cleaner" works great also. shhh
Too bad the scale can’t show you the price of R22 along with the weight like a gas pump does lol
Price varies by customer.
What does “mag it” mean? What is a mag tester?
@@georgehale9625 in theory there should be no continuity between the windings and ground since they are coated with insulation. If there was damage due to overheating it might melt a little and you'd get some measurable resistance in the megaohm range which is what that tester looks for. Notice how as the ohms go down it goes from good to caution to bad. I wonder if the ultimate test is to do it when the compressor is cold since resistance goes down as the temp goes down but maybe in that range it doesn't matter.
ntsecrets most scrolls test caution to bad. Then start them and the winding test good. If you have a megohmmeter test a cold scroll. Then after running the comp they test good. Not sure why scrolls seem to test is way.
@@ntsecrets I understand using a multimeter to check for resistive conductivity between the winding and ground but the post referred to the term “magging” which would suggest some magnetic property measurement. Perhaps they mention “megging” referring to megohms but written like they were hearing a speach impediment.
When you charged in liquid form, do you use a liquid to gas charging tool? If not, why not? Can't the liquid eventually slug the compressor?
I just charge it in and let 2 core valves restrict flow. Then the refrigerant mixes with the superheated vapor. By time it hits compressor a lot of liquid has flashed, or so I believe. Been charging this way since I started. I don’t lose many compressors.
And you do the same with 410 as well?
Yea never had a problem. I know many say not to. Yet these compressors can handle a small amount of liquid. Might push oil out. Yet it will return. None of my coworkers do any different. Now if only the evap coils didn’t seem to leak as much.....
Gotcha...alriight brother thank you for your videos man, I stay watching and learning, keep it up bro 👍👍👍
@@thehvachacker Scrolls cannot handle liquid. Have you ever seen a scroll set that blew apart due to slugging liquid? There is no such thing as a compressor that can handle liquid. If that were true, heat pumps with scrolls wouldn't have accumulators and manufacturers wouldn't have massive warnings about superheat being too low on equipment. You should see the MASSIVE disclaimer in Trane Intellipak manuals about setting the superheat for each circuit and they are scrolls. A scroll set is a scroll set and they all explode into a million pieces when they slug liquid.
dont check for any leak?!
No need it’s already been found on evap coil. Slow leak and customer wanted cooling unit a new system could get installed. This is Sunday emergency service with lots of calls to still get to.
Why does the compressor overheat when the system is low on refrigerante?
Not enough cool gas returning in the suction line to keep it from overheating
Leak
i am just trying to find out if the compressor is supposed to be hot or cold to the touch when working properly
anyone out there got the answer to my question?
The compressor when too hot will trip the internal overload so like he did, you cool it down with water hose to the point you can get a reading on the windings with your meter
@@thetruth6072 thank you
Use water hose with small towel or rag
Why do techs always charge 410 as a liquid but 22 with vapor? why now always liquid? I know you can burn out the compressor if you charge with too much liquid but I don't get it!
410a has to be charged as liquid, R22 can be charged either way. Yes, have to make sure not to slug the compressor with liquid refrigerant in any case.
@@thisisyourcaptainspeaking2259 well is it due to it being a high pressure? HFC? I'm wondering why.
@@Keegeth It's because 410a refrigerant will separate into it's constituents while in vapor form and once that happens, it's no longer 410a, it becomes a different compound at that point.
All blended refrigerants are this way I believe cause of they are a mixture and react differently to temperature if they are separated. Could be wrong but that's how I understood it.
@@MAZA4lyfe oh ok! I get it now. Thanks ☺️
I swear from this day forward I will never go to work stoned
I don’t recommend it. Haven’t done that in almost 17 years. The problems I find with those that smoke and work is dumb call backs. They might make all the correct repairs. Then leave forgetting to plug back in or turn on a disconnect. I even had a coworker pressure test a system yet forgot to braze one fitting in attic. Plus at this call on a Sunday I was near 80 hours on the week. Hard to work that much stones in the heat.
Should get a proper conoressor cooler I seen all the water jumping and not doing much when hitting the compressor
What just has to run over the compressor. I’m not looking to soak compressor. Just hit it with cooler water. Which removes the heat from compressor. Do they even make a compressor cooler? If so are the sizes adjustable? Would it fit this compressor=Carlyle 06D Semi Hermetic Compressor Replacement Update czcams.com/video/oYHpD3h4aSo/video.html

So where was the leak?
Doesn’t matter. System is getting replaced mid June
WTF where did 5 lbs of freon go to, should be a obvious leak...
It was a slow leak. This was only to provide cooling till system was replaced. I sold them a new system. Yet they didn’t want to be hot. That’s why they were trying to cap how much refrigerant went in. It was a small leak on the evaporator. It was found 2 years ago. That was last time that refrigerant was added.
A huge 1
@@christophermiller1520are you just dumb or not listening. It took two years for that “huge” leak to finally effect the unit. That means the leak was really small. Smh
How do guys like this be allowed to work on equipment.
Proper procedure would be to recover most of little remaining R22, to couple psi remaining. Then should have pressurized with dry nitrogen just to check for leak point first before wasting rare and expensive R22. Small amount of EPA regulations allowed R22 diluted with nitrogen would be easy to detect leak point. Probably it is a leaky, rusty evaporator on old R22 system. Might just get lucky and find a repairable copper elbow leak.
Lmao they still sell r22 like candy bars you know that right? It’s not rare it’s just more expensive
Use - R-422B - it is perfect replacement for R-22 - the same pressure, the same oil .
Compressor over heat what problems ?
Dumping in liquid that fast is going to bend you some valves someday...
This is only a bandaids repair until system gets replaced. Which is worse me dumping in liquid or homeowner running this system, very low on charge for over a month?
@@thehvachacker I charge everything with liquid since most refrigerants are blends. Just slow it down a little. If you crack your gauge knob it will start boiling off right there and be a vapor before it hits the valves. The old rule of thumb is to crack the knob till the gauge reads about 10 PSI higher and try to maintain that. Units that have an accumulator (typically in a freezer) can be charged must faster.
It's a scroll compressor, where are the valves to bend?
@@yourtube4423 Lol! You're right...I've done far more refrigeration than AC work. So it became a habit to think that way.
Our fridge compressor failed and It smelled like skunk and ozone
Why change unit went condenser is empty
It has a leak in the evaporator and r22 is phased out. This was only a band aid to get it to run until replaced.
HVAC Hacker, that name best suits you. You’re not a professional, you’re a gas and go maintenance tech.
Your a hack for even saying that. You need to work in the field before you talk son
R407c will be available for a long time. For those who claim you need to change the oil... yeah, kk bubba.
Use - R-422B - it is perfect replacement for R-22 - the same pressure, the same oil .
@@yuriigorg721 There is no perfect replacement... r22 is.... r407c... I have a great reputation thanks to it...
why not recharge with 422b....? especially in this case... ive been using for years with no issues
because you have to find the leak, recover, fix the leak, vacuum, charge and fiddle around. the customer would say bye bye when they heard the bid and call the next company/guy to gas it it up. short of that they'll get the local handyman or friend to put in the "unknown gas" they bought off ebay/amazon.
Confused
Why didn't you leak check this???
No reason to leak search a system that needs to be replaced. This is second time it’s getting charged back up. Therefore fix and have them deal with sales. Yet if I don’t get the system running they will call someone else.
dude didnt you read my comment?
@@rendel2358
?
@@rendel2358 i don't read through the comments
@@thehvachacker
As an HVAC Tech isn't it your job to find the leak and repair it before charging it? Stop taking so many calls if you can't do your job correctly. Your fucking up the atmosphere, and you clearly didn't take an ODP Course or you would know this( You shouldn't be handling refrigerant). Obviously if it's low you have a leak and if you don't fix it, its going to leak again. The reason they are getting rid of R-22 is because it is so harmful to the atmosphere, yet here you are charging a leaking system with it, knowing its going to leak again....LOL? Guys am I wrong?
407C is quite a bit cheaper.
Yes but this system needs to be replaced. I don’t offer cheaper options of charging a leaker not worth repairing.
Relies to much on iPads and iPhones to do his job for him.
1:10 - I hope you put that dongle back on the peckerhead before you run water, or you'll need to dry the connections. 1:15 - Nope! But, if you take the dongle back off for a few minutes, the compressor looks like it is still hot enough to evaporate any water you've gotten into the peckerhead. 1:29 - Are you now going to shake the compressor to "dry off" the peckerhead? (I guess that would be a 'No".)
No leak check?
Why would I waste my time and customers money? I also never leak search an emergency service call. Only calls during regular business hours would I leak search. I had to turn down many service calls last weekend. A r22 needs to be replaced, 410a I have another cal set up during the work week for a leak search. Do you leak search every system that needs gas?
@@thehvachacker Basically what you're saying is fill it to get them cool now, because the system is obsolete, and wait for a callback to get it replaced when it fails again
It’s no callback. I tell them before I gas they have a leak. R22 I tell them they need to replace. Yet if I gas their is zero guarantee it will last a few day. Then it’s up to them. Yet all 410 leaks a leak search needs to be scheduled. On Sunday service calls were I am telling customers there is no time for them today. I can’t bog myself down performing leak search. Emergency service I get it running yet major repairs need to be rescheduled. I won’t even fix a leak nights and weekends unless I have time. I will reschedule to come back during regular business hours for big repair work. Let me ask you. On a Sunday and you have 12 calls after this and it’s 2 or 3 in afternoon. You leak searching?
@@thehvachacker I understand. No disrespect, i'm just a guy with a side hobby interest in HVAC.
Given your scenario the answer is a big fat No.
@@thehvachacker You already wasted their money. They could've put that $900 towards a new system. If the system is completely flat, obviously there's a leak. Now all that is going to leak out eventually and mess up the environment even more than it already is.
Where’s the leak ? I tell my Coworkers don’t waste your time topping off a R-22 system . There charging $85 a pound for R-22 , why? So it could leak out tomorrow or a few months from now and now you stressed out the compressor and overheated it .
Leak doesn’t matter. It’s leaking, it’s owners know, they added refrigerant 2019. They are getting a new unit mid June.
@@thehvachacker gotcha .Do you get a lot of customers who just prefer a top off vs replacing a unit ?
I get a lot of customers who want it charged up to give relief until a repair can be performed. This unit as I said already has a down payment for a new unit. Yet emergency calls on weekend is just bandaids to get it to operate. My company has 5k contract residential customers and only puts 3 guys on call for emergency service. And we all worked from 7am - midnight all weekend.
@@thehvachacker i see . Yea them are some long work hours . I live in Vegas do I know what you mean my doing bandaid repairs . HVAC is seasonal here i vegas . Make all that money while you can .
Careful not over charge
"HACKER" Fits the title perfect... What company do you work for????
This is so weird and time consuming from what I’ve seen and learned. You really don’t need to Meg a compressor to see if it’s working. Just hookup your gauges to see if it’s pumping and if it not take an amp draw to see if it’s pulling amperage and you can determine if the valves are bad
We should collab !!!
Bill hook me up with an HVAC job. I went to school @ The HVAC Hacker vocational school. Actually went to a 5 month vocational.
Even in emergencies I bring the customer a portable unit. there’s no excuse to kill our atmosphere at the expense of an uncomfortable person.
forest fires alone, have out-polluted anything mankind has done in many years. and not just because of the natural growth it burnt, now factor in all the man-made junk full of hazardous chemicals and pollutants that went up in smoke clouds and fires. tons of asbestos, mercury, lead and many more things all blasted into the atmosphere by fires.
not to mention radiation still from Japanese nuke plant meltdown, and fires in Russia stirring irradiated materials from Chernobyl still.

This was bad , for real man , you have all those nice tools but your work was full of no no , like a man who just bought a lambo but doesn’t know how to drive , I m just keeping 100% w u , first start w changing the name

Hey my brother you going to get all types of comments but in the field it's a different story I don't see nothing wrong especially when they are going to buy a new unit why search for something that's 1st of all out of warranty and second R22 is done so that unit is a goner time for a new one these newbies don't know shyt I've been doing this for years and worked for top companies.. if we even get a R22 .. time for a new unit .. it's part of the business ask any real tech that works in the field ..
No that’s why bad tech scam people do your job right that’s people money you get away with it because some people don’t know better. He’s just as bad as you change your way of thinking and do it right there is enough corruption.
And then he says I’m gonna check the filters bro that’s the 1st thing you gotta check also evacuate and pressure check the system before you go and charge people. Famous words we can’t guarantee it will last long of course not if it’s a small leak it might last threw summer but come next year it’s empty again.
Absolutely I agree
"if we even get a R22 .. time for a new unit .. it's part of the business ask any real tech that works in the field" ... I have thankfully avoided people like you for over 20 years. I'm still using my R22 Goodman unit from 1998. Replacing parts like run capacitors, contactors, fans, and even the compressor along the way for far more cheaply than spending 10K or more to install a brand new unit which of course needs a matching indoor air handler, and a cascade of parts and labor they will try to sell you, like new linesets, new ductwork, new thermostat, etc, etc. Remember, units that were manufactured in the 70s and 80s typically ran for DECADES with hardly any service calls. Now, when they install your brand new system, you'll often hear that it *might* be good for about 5 years (I head that with my Goodman at the same time I purchased my brand new house in 1998) and they keep switching out the preferred freon. It's a racket. Thank God for CZcams and the DIY community. We can not stop perpetuating these upsell scams.
seems alot of these " HVAC techs" in the comments are slow during the hot parts of the season lmfao. The customer was probably hotter than hell and wanted cooling that day until further diagnoses can take place / replacing the system. Alot of the times the customer would rather you come back during business hours to perform the leak search cause it saves them tons in over time charge , or maybe they are already replacing the system and just want cooling until the new unit comes in.
yeah because being busy is an excuse for doing a shitty job.....
A system that's 5 pounds low wont last a weekend without leaking out again.
Love when "Techs" don't fix the problem and just add more atmokill. What a hack. Oh wait...
Problem was resolved for my client. Problem client was hot and very uncomfortable. Therefore I helped my client become comfortable. Then to prevent my client in the future from being uncomfortable. I had them sold on a new system. Which is going in around the 15th. I may be a hack yet I address all my clients/ bosses problems. We work for our clients. Keep them happy and always have work. Don't keep them comfortable and they hire someone else.
@@thehvachacker So it's about the money and not the job is exactly what you just told me.

Pressure test,find the leak ,evac, charge with rs44 save your r-22 and the customer money... 🤦🏼♂️
Why do all that on a system headed to scrap yard? This was a Sunday call on first 90+ degree weekend. I had many more still lined up after this one. Labor for what your talking about would be more than just charging up system with 22. First find leak. Most leaks are on the coil. Which this one was written up
Early 2019. Customer paid for new system a day after I was their. I don’t sell so I had a salesman go to site. Why I am always repairing old systems. I am service tech so I have to fix whatever I can.
@@thehvachacker yeah i guess i own a business diff strokes for diff folks. I do it right or don't it at all just my my way of doing things. But what your doing is WRONG!!! Stopping showing this hack stuff to kids trying to learn....
I can tell you haven’t watched any of my videos. Nothing hackery about my work. I provide top of the line service. This is not a standard service call. This is emergency service on a Sunday which I worked that day from 7am till sometime after midnight. No time for all the work you mentioned. One day you will be out of school and actually doing real world hvac work. The job is to provide comfort for your customers. My customer chose they wanted a new system. They also wanted to get temporary cooling. Therefore I have to charge system up with 22. No time to find leak which I already know is on evap coil. A coworker found a bad evap coil 2019. We also don’t use any drop in replacements of 22. Lost too many large trane compressors due to poor oil return.
Brother don’t stress it own my own hvac company best solution is to get them some ac it’s a Sunday, add some Freon and in the meantime search for a leak and have them pay for the Freon odds are is going to lead to a install so doing what the gentleman man mentioned is the correct way of doing it but it’s a Sunday man apparently this guy hardly works out on the field to understand that. Keep grinding brother you did good.
@@Matts_Crafty don’t be dumb and ignorant dude my man is doing great!
I have learned nothing from it
Sorry but I am going to unsubscribe from your channel. Seems to me like you are more of a salesperson than a tech. Either your being pressured by your company to push for sales or like the commission. Even on emergency calls you leak test. It can be as simple as a leaky shredder valve, txv, cracked line, etc. But will never know. We don't go around replacing a units just because it leaks especially a big like like that that's easy to find.
You must be slow on the first hot weekend of the year to have time for a leak search. I ran 40 service calls last Friday, Saturday, and Sunday. Emergency calls are not regular service calls. They come in through the on call service. nights and weekends. I don’t have other coworkers on the road to pick up some of the calls. These calls are to get the system to operate. Then a follow up for a leak search or major repair takes place. I don’t have time to waste looking for a leak on these kind of calls. If it’s a service call dispatched from my office. Then I have time, and if 410a will repair if possible. Many videos of me fixing coils, mostly evaps some condenser coils. Out of those 40 calls this was the only one that went to sales. A few I had to order specific parts for, don’t carry old r-22 carrier unit condenser fan motor 825rpm. If I put a universal rescue motor in then overheat and don’t last. That 25 year old system will keep running once the new motor goes in. Yet r22 systems that already been leak searched and documented, which owner wanted to replace, and still wanted it recharged for this weekend since 90 degree weather is here. It’s funny I get bashed here for most my videos fixing and repairing units many would condemn and replace. The one system that I fix and recommend replacing makes me a salesman. Yet I don’t do anything with sales. You should unsubscribe from my channel. You think I am a salesman when usually I only condemn 1-4 units a year out of 1000’s I work on.
Doing a leak search on an old R-22 unit at the end of its life is a waste of customers money.
Putting a little buuble solution on the pipe connections, ok thats fine.
But doing 1 or more full leak searches?
Why? 99.9% of the time its on the coil and not repairable. And even if it is on an area that could be repaired, sinking a lot of money into a repair on a system that old is a bad idea. Because its days are numbered anyways and the unit will need to be replaced soon regardless.
At that point your customer will be asking why they sunk alot of money into a system that needed to be replaced anyway.
