BORROWED TIME IS AN UNDERSTATEMENT

[@timbrown9305]

Anyone who has to be told that a tripped breaker needs to be turned to off first does NOT need to be putting their hands into a machine of any kind especially a monster with 3 compressors. Really enjoy your videos.

[@jonarmedpiandsecurityoffic9051]

If you haven't already, make a flyer of the teardown photos on systems like these and put in explanation "this is what happens when you don't perform preventative maintenance " and put price averages of replacement costs vs preventative cost

[@MFCSTUDIOS]

the thing is for these bigger company's is its all a Write off. they don't care as much as some people whould about just replaceing or major repairs as they just write it off there taxes each year

[@Zonkotron]

@@MFCSTUDIOS Which means to me, that much like equipment inventory should not count towards taxes (to deincentivize demolition and scrapping and general deindustrialization of non fully utilized equipment just to save some taxes) that maintenance should be a "better" tax deductible than replacement (to incentivize economical and efficient buisiness).

Chris, Platinum video and discription of RTU history and follow up of both customer mentality from 1st compressor burn out and and eventual path of destruction to the rest of the unit.

[@ShukenFlash]

You keep saying how you're just an average technician but in my experience, just trying your best, actually putting in the effort and really trying, makes you better than a lot of techs, mechanics, people in general. It can be frustratingly hard to find people who'll just be honest and actually give it their best effort. Eric O from South Main Auto always says the same thing, but half the reason people love and respect you guys is that you're actually putting in your best effort every time and not half-assing it. I wish more people still felt that way, a lot of times it feels like those of us who do actually feel like that's just the right way to do things, to always give the best effort we can, are in the minority. You folks are a reminder that there are still people like that out there.

You gotta stop calling it "preventive maintenance"...we aren't preventing anything...and the courts have ruled against us Mechanical companies for calling it such. Call it "planned service" instead.

[@walkingfreak]

That 2nd compressor that died you could tell right away that it was hardcore cooked and far more cooked than the first one that died. That was a hell of a repair and probably brutal in the cost just to replace it in 2-3 months.

[@Lembemupixo]

I know nothing about this trade but was wondering, how much can this repair cost in total in comparison to the whole replacement cost?

[@walkingfreak]

@@Lembemupixo this repair is probably 4 to 5 grand at least. A new unit is probably about 20 to 25 grand after labor.

I have a feeling that after that outlay of cash, they're probably going to wait until the third stage goes out. lol

Man I really appreciate you taking your time to go step-by-step thoroughly giving an in-depth description of what the proper procedure is to diagnose, treat, repair, and maintain these machines. Your knowledge & experience is very well versed and appreciated! Thank you for the compressor autopsy portion to allow us to discover what failures are evident. I do wonder if you may have a way to show what an actual working compressor is supposed to look like internally. Now I realize you couldn't take a brand new one apart, but perhaps one that was working that maybe had a minor defect that we could compare to to have a deeper understanding of what we are learning. I completely respect the fact that your time is valuable and humbly ask simply for the sake of educating those who seek a better set of knowledge. Really appreciate and enjoy seeing how you've evolved your business throughout these years and to see you thrive is an inspiration! Thank you, Chris!

I would've thought the no 3 compressor would've failed by now, I'd have been wrong! I wonder how much longer it will last and if the different filter dryer made the difference!

unless it's a small txv and doesn't have the option, I always just replace the guts and powerhead, the body is just that, a brass body, so no need to braze in new TXV's, a couple wrenches and you're done. I also always add an acid neutralizer to the new crankcase if I suspect acid, along with an HH drier, better to be safe than sorry. Just my 2 cents though, great work as always Chris!

Its works perfect to clean d system n very quick dry too. Its kind a nasty when using this method, but believe me, the result is super impressive. Im not saying that blowing n2 alone is not efficient. But sometimes in few cases it need to be done with this degreaser. Im learn a lot through ur impressive breakdown call video n u amazed me.

[@gibbsmeedat3954]

From what I saw in that video, the store manager doesn't seem to have knowledgeable support from a good maintenance crew. Or maybe its their own fault from cheaping out and having a "handy man" do the filters, coils and roofing. either way, I would fully expect that a manager who has their quote on a new unit denied would be frustrated and tell their "handyman" to get up there and seal anything with a crack or seam.

As an owner of some roof mounted units, what/how would I know what the correct preventative maintenance is for these machines? I'd love to prevent full equipment failure as much as I can but I'm not sure what maintenance I should be doing.

[@TheMustang781]

You should not be doing it if you don't know what maintenance you should be doing. Hire professionals

[@Brisket9392]

Periodic cleaning of the coils with water and appropriate chemical. Changing the air filters. Inspect and replace contactors as needed. Verify fan motors running correctly. Free spin to make sure no failing bearings and replace if going bad. Inspect and replace belts. Clean condensate pans and drain lines. Check wires for rubouts or secure potential rubouts where wires are contacting any metal. You can also do amp reads if you really want to be thorough. (Fans/Blower/Compressors) - Touch test the refrigerant lines.

[@2xKTfc]

If you don't wanna stick your hands into the unit (there's line voltage potentially (heh) everywhere, even where none should be) - listening to it run will give you a good idea. If it sounds funny, loopy, squeaky, wobbly, clunky, generally out of whack it might appreciate a little love. You want monotonous humming, or droning when it runs, and brief (and "clean") clicking/buzzing/thumping/clunking when it starts or stops. Much like a car - it makes all sorts of constant and transient sounds, and there's no need to freak out about it. But if it's shaking itself apart or some gears are chewing up their own guts... you'll know it when you hear it. Beyond that, your friendly contractor of choice will schedule regular maintenance and then tell you what, if anything, else they notice on and recommend for the units.

What kind of preventive maintenance can one do on a hermetically sealed unit? Dirty (from outside) condenser or evaporator would cause abnormal conditions in the system and make various sensors to trip the compressors.

Whenever you see silvery sheen on oil, it means mechanically your looking at the compressor eating the metal off different parts, or metal bearing failure. Never a good sign. Too bad compressors are not user serviceable.
