A good air wand and a compressor work quite well too! Not to mention theres no issues with wet or muddy feet during the process

another clown type video

Ive used 3m window weld myself, but ive had good luck with liquid urethane too

Once again. Where do all of these experts in the comments come from ?

Come on dude why you lying to people? I can hear it in your voice you're way more talented than that and you shouldn't be lying to people. You just making people f*** that s*** up. Why would you do that. You are the classification of a bad CZcams mechanic. You should turn your CZcams mechanic degree back into CZcams!!

Two stories: I work for a company (refrigeration mostly, but also HVAC) that constantly deals with this recurring issue of condensing units tripping on high head pressures every summer. This has been getting worse with each subsequent heat wave, to the point where the company started subcontracting a third-party condenser cleaning guy because it was getting to be too much for the limited number of technicians we have. So, I was on a service call a couple years ago where the condenser was clearly plugged, and it happened to be that the condenser cleaning guy was also going to stop by while I was onsite. I decided to test this out and hooked up my gauges to see what the before and after pressures would look like. The guy set up his pressure washer and started spraying water at the condenser in skillful fashion, and I made sure to notice he wasn’t bending any of the fins. As expected, when I started up the condensing unit, the pressures had dropped and we were happy with the results. What I did not expect, however, was that 10 minutes after he had packed up and left, the pressures rose back to where they were previously after the condenser had some time for the water to dry out. I was still new to the company at this point, so I just let it pass, and set up a sprinkler to water the condensers, as we normally do, to keep those head pressures down throughout the summer. Second story: Just last week, I had a fellow technician show me his method of cleaning condensers, knowing he’s had quite a bit of success with his calls. What did he do? He removed the fan, and used compressed nitrogen and a small fitting to spray a focused stream of nitrogen at the condenser from the inside-out. This pushed out A LOT of dense fluff that had been packed in between the fins from years of washing out the condenser with water. Granted, this was a messier and dustier procedure, but the head pressure came down and stayed down (no drying time in this scenario, obviously, because no water was involved). By the way, this technician is young. He has been in trade for only about 6 years, but I was willing to learn from him. Just because someone touts that he’s been doing the same thing for decades doesn’t mean it is the best and only way. I think the point of the video is to give an option to homeowners who like to take matters into their own hands. I get it. I see the sentiment in the comments that no one likes to break the bank to have a technician come and do what you could have done yourself. But I wanted to share my experiences in hopes that those who call themselves experts in this field can learn also a few things, so that homeowners can find better value in paying for good quality service than in looking for the next clever hack floating around on the internet.

Oh man, I am not an expert, but I can see these coils completely corroded. These fins are falling apart.

Flick the breaker and perform an inside/outside inspection for loose wires.

The sensor I guess that’s what I will ask for at the parts store,a sensor.

Great video in getting someone injured!!!! Electrocution if wires are old and becoming comprised. Had a client end up in the hospital......

First off cut the disconnect then wash at not so high pressure and especially sideways always rinse up and down it will for sure bend the coil fins resulting in airflow restriction if theres alot of build up then use the viper solution and if you want to clean it professionally it is essential to remove the fan to rinse any wet thick dirt and vacuum any leaves with a wet vac i learned all that in trade school and working in the residential and commercial field here in South Texas were always doing coil cleansing especially on the rooftop units of inns/suites commercial businesses and of course your local residences so props for making this video but its slightly incorrect man but if you want a full condenser coil cleaning that's the way to do much love bud and yes my channel is flowmaster records i also own and run a record label on my spare time was signed to warner music group in my prime when i was around 19 im 31 now but HVAC-R is my preferred profession if you need tips on how to do it properly im sure there are youtube videos on it but as a universal certified technician that's the proper way to do it. It will take a little time to disassemble the fan all you have to do is just unscrew the fan panel and gently lift it to hang on the side to not mess up the fan motor wiring but other than that its easy as 123 hope this helps you in the future

If you found this video and you want to avoid this, it's super easy. Oil cooler, 180 thermostat. Thats it. And if you have a pre-eagle 5.7, get eagle heads put on it. You will never have a premature lifter failure. It's a lot more rare than people like to think. Also they will sound similar to this on cold start due to header-head leaks. Very often, the header studs stretch or crack on these engine which will make this noise. Typically, once it warms up, it will go away if it is the exhaust making the noise

its a good idea to turn the unit off may damage the condenser fan bro.

That anybody can do. except 99% of liberals who own nothing, but "have a guy" (that takes care of them)

Make sure you put the long screws into the coil

That’s a $3-400 3/8 snap on socket set ! Wow I am looking for one and you found it haha lucky man

Should i spray the relays as well? They are dirty too?

If all AC units had this type of coil protection that would work. With my lennox AC, I would just have wet but still dirty coils.

Try that with a train unit 😂

How do you get the leaves out of it.

No way I'd do that. It's better to push the dirt back out from the inside with much lower water pressure. Clean the drains and under the compressor while you're in there

Use propane to get her to fire off put your torch tip into carburetor same place you poured your hot sauce don't light torch just turn on sticky in pull cord it will bust off

Was always wondering what the hell that beat ass looking hand grenade outside the unit was. Good to know.

Old, simple, tough, and no safety features. That's how I like my equipment. Don't tell anyone, I still use my dad's metal gas can with a metal spout.

That's the real deal

I never mix electric with water, unless you love living on the edge, always kill the main power and let unit drip dry for a few mins before restarting

Not the way I do it. Cut the power, remove the top and spray from the inside out. Otherwise you might be pushing the dirt further into the coil.

My grandfather had a little lawn business when I was in junior high he had about four or five yards he did and he had a mower somewhat like that and I was 5 ft nothing -100 lb😂 arms the size of toothpicks and that was the mower I used well it was a little bit of a newer one but almost the same design

Looks like the old Yazoo mowers. That was a beast as well.

The way I clean mines , first i blow it with your leaves blower and then used the hose going up and down not too much pressure with the fan off

transmission. Chevy truck. Needs to be hauled to the. Scrapyard. and not do any work on it.

Complete bs, my unit has a different plate with no easy access to the coils.

Could you imagine all the warning labels that would come on that thing if it was built today

Crack house had the stove going out back

A warning here from an actual incident. 2 or 3 months ago I pulled the disconnect and washed my ac unit out. Last week it stopped running and I pulled the top and investigated. (I have a degree in electronic engineering and 40 years experience troubleshooting electronic/mechanical equipment.) I found the source of the problem, the wiring to the compressor motor passed through a hole in the sheetmetal between the control circuitry and the compressor. This hole didn't have any bushing in it (like that from the factory), and the wire had been vibrating against the edge of the metal until it rubbed the insulation off. The wire was shorting to the metal frame of the unit and from the looks of the burnt out metal for quite some time. If I had not disconnected power when I washed it out earlier, at a minimum, I would've had fireworks or worse killed by electric shock. So please don't wash out your coils with power applied to unit, it might take your life!

This just came across my feed. DO NOT DO THIS WITH THE UNIT RUNNING. Not cause of any electrical hazard - you risk damaging your compressor. That unit is the heat rejector it’s supposed to be blowing warm air - and when you’re spraying COLD water on the coils it’s going to drop your head pressure significantly, lower your compression ratio and overheat the compressor.

I hate dog hair

How are they gonna recover before “calling the ac guy” your a dipshit in all ways

Can i use my pressure washer or not ? And my second question would be, Do i have to stop or wait until the ac stops?

Cool!

It's amazing what the markup is on AC systems from the first wholesaler to the public end user

This reminds me of them stand behind mowers just a really old one that u walk behind instead

Nah, I'll never own a home, but you back flush coils, and that requires removing the fan, and blowing the opposite direction of the airflow

That front wheel is IT man😅😅😅😅

Very cool! I am interested to see one working!

That is so cool. What year were these made?

Stop taking off the cover and don’t disconnect the power. What else do I need to do wrong?

That should have a p-trap on it. It’ll hold water in the pan while the blower is on without one.

Can we get a better look at your hose adapter? That looks useful for aure.

Only good on single row coils...
