I’m 20. And I went from residential installs, to commercial hvac/r service. It’s a whole new ballgame. Miss residential but I took the commercial step to get a deeper grip on hvac and refrigeration.
My Votech instructor when I was in school was and still is a engineer for York. He gave us a 50 ton package unit wiring diagram and told us if you can read and understand this, everything else you'll see will be easy.
One tip i think can help anyone starting out. Cycle the equipment 2 or 3 times after a repair. even better to test it more than once during a service call if you arrived and the system worked just fine.
Regarding drain lines, I’m in Raleigh,NC. On a maintenance I bring a gallon of water to the attic with me as well as about a 1 inch piece of silver Solder. I always run a brush down the trap yens into a pan fitting and if there’s not a clean out I will often install PVC unions(sometimes at a cost with their permission). I physically test the drain with the full gallon of water and I leave silver in the trap. Visually inspecting pitch cannot be overstated. I think drains should be number one!
As a service technician in the Chicago area I would say that this very well can be applied to heating. Our drain lines would be condensate traps and tubing for 90+ furnaces. Check gas pressures, make sure the equipment achieves second stage if applicable and make sure it doesn’t go off on limit. But other than that this would be a few differences for heating! Wonderful video!
Speaking of drain lines; a good idea when doing pm, put in a few of those drain pan tablets to help reduce sludge build up in the drain pan. That’s a must in high Rh areas. It’s cheap insurance.
I have something to add. Don't open a sealed system to atmosphere when the surface tempature (line set, coil, ect) is below dew point. One example is pulling a coil to clean it. Pump the system down and wait for the lines and coil to warm up before opening the system. If it's below dew point, it will form condensation inside.
Not HVAC but I recently spent half a day tearing a brand new jet pump apart to try to find what was hanging up the impeller. The problem wound up being the voltage jumper was set to 110 not 220... I’ve put in dozens of them that were all factory set for 220... but not this one. Felt mighty stupid.
Lol when I read the title I thought it was a list on things to do to earn at least a 100k lol....Guess every individuals list would be much different for that topic.
Good list. I'm guilty of forgetting to make sure it's draining after I blow it out and clean it. "Running AND DRAINING" is what I'll be saying to myself.
We did troubleshooting and reading schematics using a book called UGLIEY'S by brown publishing. I don't know if this book is available anymore. It's been a long time since I was in college.
The way I understood it, think of a highway with tolls, even though your 4 lane highway might come down to 2 lanes for a toll, it still doesn’t slow the travel between the tolls.
@@davidmarsh7396 yes it does. when 4 lanes are busy and you need to merge all the trafic to 2 lanes u saying it doesn't slow? something is wrong with your calculation. privious reviewer right. it doesn't matter how much bigger the hoses are, the work of flow is limited to 3/8 Schrader valve.
I think its just plain marketing at its best to trick ppl into buying something they may not need. ? JB website for there vac hoses says hose diameter won't make a difference.
Different mfgs. have different methods of printing schematics & sometimes you need a factory tech rep to explain certain things about a certain type of diagrams. Schematics are not always intuitive.
Also not Equipment, related... don’t take anything personally. It’s not personal. The wire didn’t internally short because it wanted to add to your bad day.
DRAIN LINE CLEANING, BEST PRACTICE: After flowing clean water through, then BLOW A Dual-PIG though it!!!! (A balled up wad of zero sized steel wool "PIG", followed with a BALL of spongy foam PIG behind it. Then rinse. VOILA! SCRAPED OUT CONDENSATE PIPE!! COOL PIG BLOW VID: czcams.com/video/6sBO0lO7AFk/video.html
Guys not knowing the difference between series and parallel is one of the biggest things I see. If you can differentiate that then youre good with electrical
Anyone else feel disheartened when they watch these? I feel like I’m doing alright and getting decent work done and then Orr comes along talking about checking VFD’s, verifying multistage operation and checking static on all systems etc, and I get sad again like I don’t know what the hell im doing out here. Some of this stuff y’all talk about just leaves me scratching my head. Where do y’all come up with the time to do half this stuff on a job? I feel like I’m kicking my butt to death trying to do four to five maintenance visits a day, and there’s always stuff I simply can’t do because of time.
Don't feel bad, I have been doing HVAC for 30 years. I started at 15 years old and am now 58. I have done everything from residential installs, residential service, commercial hvac, and now industiral hvac and trust me this field is so vast no one can know it all. I know like 20 percent of what I should know. We are thrown to the wolfs everyday and expect to know it all. Unlike other fields who specialize in what they do (doctors, lawyers, accountant, engineers) we are expected to be experts in it all. There is no way. Trust me if you did what these guys are talking about you would be a a call all day and possibly get run off the call by customer and eventually be fired for being unproductive. Employers don't want experts , they want the blow and go guys. Those that can do 5 to 6 calls a day . Get it done mentality, not those that fine tune a system to the inth degree. I work for a company who has a task list on equipment that is several inches thick and the stuff they want you to check is rediculus because they paid some engineering consulting company to tell them that this is what is to be checked. These guys have never done a service call in their life. I myself only check amps and temps like delt T on systems and get a good feel of how well a hvac equipment is doing. Checking static pressures superheat and subcooling is not needed on every call. But if you don;t have that written down on tasking your called out for it. Sorry for the rant. This field is frustrating, made harder by cubical rats thinking up ways to make themself look good and you look bad.

As I’m in school, these tips are like cheat sheets, thanks so much

How long did you do residential
Same question..how long did you do resi til you said okay time for another step
I haven't heard anything about Andrew in a long time. It was nice to hear him again.
He's with navac now 😉

Do you still happen to have the wiring diagram?
@@hvac_audaz_firme you still on the roof waiting for his reply?
I'll be adding this to the playlist I send to newer technicians and the playlist I listen to while going between calls.
This grizzled vet stays on top of the game thanks to you guys. Newbies beware the bad habits are easy traps to fall into. Thanks for all you do!

Congrats mate, this channel has thought me a lot of tricks that school isn't teaching me.

What's the silver solder for? Why do you leave silver in the trap?

Who downvoted this? Every tech should know all of these.
Lots of shady techs don't like people sharing knowledge.

Awesome video, I’ll be utilizing these tips in the trade. Appreciate how thorough you explained everything! 👍
I’ve had to use a contactor to trouble shoot control voltage before; when my tools got stolen out of the van lol
Read the manual?!!
I thought they were knee pads!!!🤔
Great tips here, 20 year tech still reading the knee pads!!!
by far the best youtuber to learn from in HVAC
Congratulations on 100K!
Congratulations on 100k.
Top notch content and format with other pros! Eye opener for this rookie. Thx!
Another winner, great video! Keep it up.
thanks for the videos.i got epa 608 universal following your videos ty brenaman and same others johnstone supply and other
I'm still learning.
And I'll always being
Congratulation.! Great knowledge and advice for troubleshooting.
Thanks for sharing
I don’t normally subscribe but when I do i do and I have. Thanks.
I agree to many time I've came to a service call and the air handler didn't have a proper pitch
Lol when I read the title I thought it was a list on things to do to earn at least a 100k lol....Guess every individuals list would be much different for that topic.
Awesome episode. The best of the best techs
Great tips 👍
Big Tip guys. GO FOR WHATS EASY FIRST
Congrats 🎉
“The best way to learn how to learn to read schematics is to read schematics”. Yes that is how I did it.
🤣
Good list. I'm guilty of forgetting to make sure it's draining after I blow it out and clean it. "Running AND DRAINING" is what I'll be saying to myself.
If you put 2 fans in the middle, would they be exhaust or intake?
Is that as good as putting them at the beginning and end of the system?
How about venting the condensate between the evap and the trap instead of after the trap. I see that a lot

Costgard condensate drain seal
I don't understand the larger hoses. You still have to go through the 3/8 ID Schrader valve area.
The way I understood it, think of a highway with tolls, even though your 4 lane highway might come down to 2 lanes for a toll, it still doesn’t slow the travel between the tolls.
@@davidmarsh7396 I do understand it, but I'm not so sure I believe it until I see an exact comparison of the same setup, just different ID hoses
@@davidmarsh7396
yes it does. when 4 lanes are busy and you need to merge all the trafic to 2 lanes u saying it doesn't slow?
something is wrong with your calculation.
privious reviewer right. it doesn't matter how much bigger the hoses are, the work of flow is limited to 3/8 Schrader valve.
I think its just plain marketing at its best to trick ppl into buying something they may not need. ? JB website for there vac hoses says hose diameter won't make a difference.
It's about the pressure drop. Same way why length and diameter matter for a cap tube.

I got idea master.
In god will.im going to Canada to be HVAC tech...
Hey is there a way i can contact personally so i can run simething by you about a package unit
Nice tips
👍
I thought you ment 100k$😂😂
Here a tip don’t give two f about the job after the day is finished 😐
I'm still working on this one. Would definitely sleep better.

Just be a Tinner...
Hi
Schematic is like a house plan .
If you know the sequence of operation for the equipment it’s much easier to read schematic
Great videos past not to complain... This not good, the apprentices that i work with got nothing
Joins commercial business who explains nothing to the owner when there is a problem but gets paid. Step 1 and that's for free
Not Good... edit out the drinking...
