Agreed, working in IT for the last 15 years I'd love to do something different. I mean I've always had an interest in Agriculture, I did that for a summer and loved it but there are not many jobs available in the UK for someone with not a great deal of experience, not many people are willing to train someone with limited knowledge since it may not be a stable investment.

Dirty coils lead to high discharge pressure leads to high temperatures leads to oil breaking down leads to plugged driers and metering devices.

[@HighestRank]

Rewired(eliminated) variable demand exhaust leads to exhaust drives rewired for full speed motors and insufficient(nonexistent) make-up air unit leads to 100% open package unit dampers and open economizers which leads to excess air flow over condensers plus lack of increased pm is what leads to dirty condensers.

[@wonderhomie2011]

Exactly my thoughts. High temp and preasure breaking down the oil. May want to do an oil change cause if its on the TXV and plugged the drier, the sump of the compressor is full of it. He may wait till the compressor fails.

I've done a lot in automotive AC, done a lot of reading. What I find over and over again when I watch your videos, almost no one in Automotive really understands how AC systems work. I have learned more from watching your videos meant for other HVAC techs who already know the basics than I have from schooling, ASE Master techs, ASE AC books, and ASE master trainers. What I have learned from watching your videos has cut down AC diagnostics times and wrong parts replacements substantially. A job that normally takes me 3 hours to diagnose is done in 20 minutes sometimes because you have taught me about temperature and pressure differentials without having test ports all over the place and just going by line temps. In a couple of your videos you covered operational theory of some of the more complex components, which perfectly covers the simplified versions used in automotive. If you ever get sick of restaurant HVAC work, you might try your hand at automotive AC, you'd likely be better than 95% of the guys out there doing AC on them. You'll just have to learn to fight around interior panels. Awesome videos!

[@gadgetroyster]

Did you smell the refrigerant for burnt oil? Or test for acid? (Pretty acrid / nasty smell) Sometimes the burnt oil is what causes sludge, and you know that dirty condensers cause overheating which in turn can cause the silica gel to break down. Another unorthodox test I used to do was put some silica gel beads into my hand and add a few drops of water. If it did not get hot then there was water in the freon which also caused the gel to break down as gel beads plus water gets quite hot and turn to powder. I never did figure out how the water got into the system other than an incompetent mechanic.

[@jake2213b]

I was told years ago when they started to recoup freon that it would be clean and used again. You are the first one to see cleaning R22. What my job do is we would clean and reuse oil. It is tested for acid and it is filter and dried out from moisture.

Clogged drier is interesting. We have an account where return air is typically high 80’s to mid 90’s. Since your unit is pulling in 100% outside air I imagine it is similar heat load, since I am in East Alabama and have super high humidity all year. Those units had issues with filter driers due to high superheat from heavy load on evap leading to poor compressor cooling. Oil breakdown and premature wear to compressor. We put in 30 cubic inch driers and still change half a dozen each year.

The rest of the system was spotlessly clean. Can't complain after 25 years of use

As a former carpenter and current HVAC technician can I offer some advice. Drills are for twist drills to bore holes in things. An IMPACT is for sinking and removing screws (fastening device). That being said you are correct about it being about trigger control.🇺🇸

I have tremors that affect even trigger pulls, so I just drive everything by hand. Slower, but a lot fewer stripped screws.

[@nerdywolfi]

there's a place for impact drivers - people just going crazy with them where it's not appropriate is not one of them :D My small 12V DeWalt impact driver is pretty nice to handle and if you are careful with the trigger, you can use it without stripping out all the screws every time. Using a proper drill with torque settings is still preferred for tightening bolts and screws cause that way you get it right every time without having to think. You can also get "torque sticks" for big-boy-impacts to limit the maximum torque you can tighten up a bolt. As for loosening bolts and srews, I prefer using the small impact, but if you happen to come upon a badly rusted screw, you can easily rip the screw head off (but that probably would've also ripped off using any other drill as well).

That intro was the best... When i was an instructor i would teach that to all my students based on my years of experience with striped screws especially on carrier units. Simple yet , most do not care... I have bought thicker screws and replaced thousands of stripped screws over the years...Mechanics 101.

[@HappilyHomicidalHooligan]

Yup! If you're going to use a screw-gun to install machine screws, either: 1) Get REALLY good with trigger-control (not recommended)... 2) Use the screw-guns clutch properly (semi-recommended due to people getting lazy or forgetting to set the bloody clutch)... Or 3) Use the screw-gun to drive the screw in almost all the way and use a screw driver to snug it up (also semi-recommended due to people getting lazy and not stopping before they've snugged the screw down with the screw-gun and stripped the threads)... When I was in Electrical Trade School, if an Instructor (didn't have to be your Instructor) saw you use a screw-gun to install a switch or receptacle into a device box, you automatically fail that Practical Exercise right then and there...the School reused the switches, receptacles and device boxes for as long as possible to save on costs and they were replacing too many boxes due to stripped screw holes due to screw-guns being used on them so they implemented the Screw-gun=Auto Fail policy... It worked, the number of stripped screw holes dropped immediately after the students got it through their heads that the Instructors/School were NOT kidding about it...

I WILL NOT throw my impact in the trash! 😂😂😂 in the 3 years that I’ve owned the thing, I’ve never stripped anything out with it. It’s just like a pneumatic impact wrench that you use to work on your car (I have one of those also), which works basically the same way, you gotta know how to modulate the trigger. The trigger on mine has a variable speed. I did break a couple of lag bolts when I first got the thing, since I still haven’t quite figured it out yet. I will say though, impact drivers make terrible drills.

Unless you are doing woodwork and trying to drive 2+in screws, then impact drills are very nice and prevent stripped heads and beat out drills every time. Other than that, their whole deal is really putting a lot of equivalent torque on a fastener.

Go back and do an acid test on#2 and if it tests positive for acid add some acid away to the system and you could avoid having a burnout! If all of this pans out let the customer know that you went the extra mile to save the compressor and you hopefully will have a customer for life! The others who were looking at the system before you damaged the condenser coils and most likely didn't purge the air out of their hoses and allowed air to get in the system so acid is likely in the system now and is causing the sludge that clogged your filter dryer!

I’ve actually seen where a drier failed and put those beads through a system. It was on a truck that had a failed compressor, didn’t have a drier in stock and the driver didn’t want to wait. Took a gamble and sent it without a new one, it failed week later and ended up needing all line and coils, it was a sleeper too so it had two exap coils.

[@silasmarner7586]

We have air dryers to lower the dewpoint on some low temp probers and the dryer has two reservoirs of those beads of death with a switch than passes air thru one, then the other while the first one purges and re-dries, and eventually they disintegrate. Then the powdered desiccant gets into the terminal air filter inside the dry chamber, getting blocked, slowing airflow, causing condensation, and freezing up the prober system.

what neat toys you have! i remember my electrician helping the MMs carry in 5 gal buckets full of hoses and gauges. something that size would have taken a week at least to troubleshoot. bluetooth. amazing.

Best intro ever, way too many do not seem to understand that!

Love your videos I fix computers and reflow mother boards and solder all day.

impacts are great, the knowledge of how to get the tool to do the job intended is priceless..the newer milwaukee impact i own has the option to cut off holding on the first hammer strike or even set the torque very low and is the appropriate tool on fasteners instead of using a drill made to drill holes mutch like using duct tape to seal ductwork...

I’m not an AC tech, but I really enjoy your videos!!!!

Great video! I agree with your diagnosis. Dirty condenser, and evap running far warmer than normal due to 100% outside air, must have had compressor discharge temps going sky high. With mineral oil, that's gonna cook it, and it then leaves wax deposits everywhere, especially in any already occurring reduction in the system, such as the TXV orifice and the multiple passages in the drier. You're fortunate that Lennox didn't use a multi-orifice metering manifold like some Trane Voyagers do...those are a nightmare with a similar poor operating condition (high head pressure; high superheat/poor compressor cooling) when those orifices plug up with overheated oil wax.

a loose belt would wear down the pulley faster because it is more prone to slippage, which causes ablation. a correctly tensioned belt does not slip on the pulley as it has a friction that prevents it from doing so, indicative of efficient energy transfer.

I’ve always said a sheave is on the motor and a pulley is on the blower.

They're one in the same.
