Gotta say, as a person coming new into the trade, I watch a lot of other channels on YT for HVACR but yours are probably the easiest to follow and most informative/enjoyable to watch. Keep it up!
@11:35. when I closed my eyes for a couple seconds (watching this way too early in the morning haha), the sound of the machine instantly took me back to being a teenager working with my father during the summer on his HVAC jobs while he's doing residential and commercial services. I never got in to the industry myself, but that love of diagnosing a system, looking for the big picture, finding the thing that someone else overlooked has never left me, and I do technical support today. You get that tingle in your brain, you know? Found this channel from Technology Connections recommendation. Thank you, sir. Keep up the good work, in-field and on YT!
I just saw like 3 videos and I love the content what company do you work for or own, seems like you're a good and honest technician you earn another loyal fan of yours, probably I will meet you around since I live in Indio it's close, and when I drive I see a lot of Van's from different companies, in case the AC in my home breaks now I know who to call..
Had the same issue that you had on the smaller carrier, except my issue was a cracked motor mount assembly raising all kind of hell when I first got to it. Didn't wear down the blower motor pulley, but it did on that plastic blower wheel pulley, and the belt looked just like yours. Good job with the leak check. I prefer big blue.
thanks for watching, I am going live a little early today 12/24/18 at 12:00pm pacific standard time come on over if you can and check it out ua-cam.com/video/rDd469JwYww/v-deo.html
Great tip on the soap bubbles, everyone I've worked with uses the fan spray and it is harder to see since you have bubbles forming right away. I'll be doing it your way from now on. I would have never thought it would leak through to the connections. I will be checking those now also. Great videos.
Gas flow inside electrical wire jackets. This phenomenon is actually used by automotive oxygen sensors to provide a stream of fresh air to the sensor. "The sensor receives the reference air through the connection cable. This means that the connector must be clean and dry. Contact spray, and anti-corrosion agents etc. are forbidden. The connection cable must not be soldered. It must only be crimped, clamped, or secured by screws. " source: luniks.net/lambda/sheets/sensors_oxygenlsm11.pdf
Those condenser coils look like they could use a cleaning, don't forget, a falsely elevated head pressure (due to dirty condensers) will elevate the suction too, in other words, after the condenser is cleaned you may realize now that you're slightly low on refrigerant.
Amazing the climate differences. March 13th I definitely was on a no heating call probably resetting the high pressure switch on a weil mclain boiler for the 30th time
This is typical of what we find very often! We find copper that has been bent during installation or repair as the source of most leaks! Of course Schrader valves leak but i suspect the stress of the bend causes more leaks than people realize!
I'm a little surprised you guys (as in americans) still measures AC:s and heat pumps and sometimes even direct acting electric heaters in BTU/h or even Tons. I mean, they're not unusable units, they're just not easy to compare to something else. I mean, if a heatpump uses 1 kW of electricity and produces 5 kW of heat, the COP is 5, nice and easy. But if it uses 1 kW of electricity and produces 17000 BTU/h of heat, it's a bit tricker to do the math, for no real reason other than being stubborn..
Wao good job brother I watching all you video because I star working again on commercial units like package unit daking, trane and do PM all that thanks for all you videos 🎼🎶🎺🌅🇵🇷I’m from Orlando Florida 👍
@@HVACRVIDEOS I actually do a different type of service work which lends it's hands to troubleshooting all the time but the way you tackle things in an established manner is what keeps me watching
Go for it, my friend!!!! It is an awesome trade to get into. It also will pay the bills, without worry! The demand for good HVAC/R Techs will only increase, as time goes by. There are also, a lot of "work-while-learning" programs out there. If you put the time in, that time is going to reward you, immensely! Good luck, my friend!
@@leostechnikkanal I am not sure about yours; Leos, but I was able to take 2 years of HVAC, my Sophomore and Senior year of High school. But like I said, I am not sure if you have a Vocational School, where you live? If so, definitely sign up for it and just keep on furthering your education.
The pointed out pulley was actually the sheave. A adjustable sheave from the looks, anytime I replace a sheave I also replace the pulley because if the belt mirrored the sheave then it's common it weared the concave of the pulley also. And I would have liked to see exactly how it is you would check the electrical for a leak. Does wiring really hold pressure?
No the wiring doesn't hold pressure but the pressure control is encapsulated and the wires are sealed in it. So if it fails and starts to leak internally sometimes the refrigerant will find it's way out of the plastic jacket around the wire.
Kind of...? I know exactly what he’s talking about because it happens in telecom, sort of. Not so much anymore, but what we used to do (as I’m in telecom, not refrig. I just find this channel interesting) is that there would be massive fuck-off air pumps blasting down into the cable sheath. This was done because it drove out moisture and made things corrode a bit less. This is slightly before my time, so I don’t really know how effective this was, but with massive trunk lines where you would have your bundle inside another sheath acting as a pressure vessel, apparently it worked well enough that it wasn’t a complete waste of time. They do this for offshore power and I think (not sure though) fibre cables that run on the ocean floor, because even if the traffic across that line is all fibre, you still need power along that cable for repeaters, as you can’t blast light down a single stretch of fibre forever. So those cables still carry power and diagnostics for the cable itself. This is also useful for electrocuting (as in killing) sharks, because they will bite into the power lines which run on the outside of the armour, where the multiple fibres live, and kills them. No kidding, this is actually designed into the cable. There’s various theories as to why sharks attack undersea cables but it is absolutely a thing, and the cables have defence measures against that. One of the reasons Hurricane Sandy was so destructive to the telecom network is because it took out these pumps, and the airtight cable pits started to flood. Once water gets in, it never gets out again. Which is kind of the point of making sure it doesn’t enter in the first place. Hope this clears things up, because the same thing will be happening here - just you don’t want it to happen here, whereas for old telecom trunks that aren’t just fibre now (which is what replaced all the infrastructure in New York), you *want* to force air down the cable duct. One more use is to find potential breaks of cable damage. Because the volume of air going in versus coming out is a fairly well known quantity, if you’re pumping too much air, that can assist in finding cable damage So yeah, we use this in telecom a lot!
Don’t add the dye it is a contaminant. Oil and refrigerant is all their should be in a system. I’ve found the dye to clog cap tubes and pistons. I use an ultrasonic leak detector. It was expensive but I find leaks others techs could not find.
the pulley was worn too bad. If the belt get so deep it gets stuck inside, the flanks are no smooth V anymore but more U like, if you tighten the pulley up to get the belt riding on the correct diameter it will wear down fast due to the contactarea not fitting to the shape of the pulley.

I’m in school for HVAC, when you added more refrigerant then found out the system is leaking, did you vacuum it out? Or did you leave it in there to leak?
Ricky32908 if the unit holds less than 50lbs you can recharge it. If it holds more than 50 then you have to keep records of the loss. Eventually the unit or system will have to be replaced just from the expense of the refrigerant.
Hey man, found this channel not so long ago and I’m very interested! Especially considering I’m not a fridgie, haha. I can’t help asking though - are automotive air conditioning systems much different than powered ones, apart from what drives the compressor itself? Would many of the hints and how to’s you do apply in automotive parlance, and vice versa? Cheers, from Australia!
Yeah when encapsulated pressure controls leak often times it will leak out of the jacket of the wire on the other end. It will blow your mind when you see it for the first time

Why not adjust the pulley instead of replacing it?
