Yo brother, I’m the service manager for the company that’s on the sticker of those units. I cross referenced the dates the contactors were replaced and I can tell you it definitely was not us. Can you blur our name out of the video. I don’t want us being assumed we were the previous contractor. I did some heavy research using the background of your video. It looks like you are on top of a mattress firm in north Olmsted. Could see the “W” apartments in the background with an Ashely outlet. We’ve never serviced them and I can’t find out who previously was in that building
Let me see what I can do about that, I’d have to remove the video, edit and then put it up again as another video. There may be a way to blur it using UA-cam editor. I pinned your comment to the top so it will be the first to show up.
So you speak like a street kid, you’re also trying to say you’ve never service those units but your stickers are magically on them! It’s simple ask the customer what company was there!
@@andrewgilbreath1331a comment on UA-cam proves nothing! How in any way shape or form has this person proven they’re a service manager much less from that company he claims! How did he prove it wasn’t them! I’ve never met a service manager who would speak and being a conversation with YO, highly unprofessional! Stating they’ve never serviced those units, so their stickers magically applied them self’s!
For a quick test next time tonsee if the ecnonis calling. Just take the jumper off y2 and if the compressor for y1 shuts off you know its calling for economizer. Can always just pull a wire off the enthalpy sensor too.
Not an HVAC guy but I know a little bit. You must be one of the rare ones, out of the 5 different channels yt recommended me today you're the only 1 that knew what to even do. Thanks for knowing your stuff
Exelent job sir! The SH is probably not accurate. I had some time to play so I did some testing on a York adding liquid line ports. Liquid line ports were 30 psi lower than the discharge ports. I had heard it could be anywhere from 0 ~ 35 psi, there's nothing like actually seeing it. I don't know why manufacturers are so determined to put ports on the discharge line. The only way to check charge is to weigh out and in, a time consuming process. Oil on the condenser maybe from brazing in the filter-drier.
Man what a dumpster fire, so bad that a previous company service manager saw their sticker on the unit and did the research to make sure they weren't responsible, lmao bro well done with the big picture diag, I love to see other techs/companies that still give a darn about our industry.
I guess I would just write it up as a recommendation to the customer explaining the reasoning and then let them decide. If they decide not to replace the motors just have them initial that you brought it to their attention so you can reference it in the future if you have to come back.
Appreciate your meticulous testing👍 Obviously, the previous tech was lacking in the theory-of-operation of these Carrier units. However, routing the thermostat wire through the economizer tells me that previous tech probably shouldn’t even be in the HVAC field at all. All those loose terminal screws on the contactors was definitely a fire hazard as you pointed out.
Awesome comment!! It's a solid 5 on the 'Yabba dabba do' scale. Us lesser beings who are more on the residential side of things, see this with a mis-wired capacitor. Condenser fan motor going in reverse. It 'kinda sorta' works...or not
@@Mike-xe4fk war ha smokin Bro ?? At least tell me what & how, driving me nuts. Had one's case blow apart on me once, but reversing directions is interesting
He couldve just factory charged through the liquid line them fired up after without even checking pressures to see that his blower was going backwards smh 😅
Nice video. I've only worked on 3-4 units that run on 3 phase. Love how fast u were able to swap and fix it. But an in depth explanation (like what you did with the loose wires) would be greatly appreciated
Cool, thanks. I believe the loose wires you’re talking about may have been the spares in that multi voltage transformer. I didn’t do anything with them
@@HughesManHVAC no I meant like you explained why the wires need to be tight. I’m curious how you knew what to reverse when the motor was running backwards
@@DCHVAC it very simple All 3 phase motors the rotation set by swaping 2 phases. On singke phase I have fix rotation by taking the motor apart and flip the stator over and put motor back together.
@@HughesManHVACAnd add to that, you have no idea what all the previous tech did, only what you can deduce from your inspection, and for all you know they could have recharged the unit if they found it was low on refrigerant.
First 2 digits on that Copland compressor will tell you its dates. If it’s newer than the unit dates maybe carrier invented time travel when they manufactured that rooftop
Why do you did you put back that cleaning drain pipe you should have let it drain down to the roof it'll get dirty if it's straight up pipe for the drainage
Buenas tardes Chris, la onestidad es un gran trampolín en conjunto con los excelentes trabajos que realizas eres único en el ramo, te confieso una cosa. Ya empecé a soldar con equipo autogena pues viendo cómo lo haces en tus videos me di valor para hacerlo, claro que con las debidas precauciones pero ya lo hice y eso fue gracias a ti. Saludos desde Coacalco Edo de México. Gracias Chris. 🙂
My central air unit quit working. Replaced the two fuses and it worked again. Now it’s not working again. It 26 years old and getting replaced in 5 days. I’m heading out to buy some more fuses. Am I wasting money? Just trying to keep the family cool.
I only recommended it, it was in fact phased improperly and if you have ever dealt with facilities companies it’s best practice to at least note and or recommend an issue just to cover your ass, if that motor fails after I make my recommendation they will consider it a call back and we will eat the cost. So I note and recommend anything that I consider a potential issue, so it is documented. Facilities companies will approve or deny any repairs they don’t want to pay for. Is that motor bad? No… was that motor phased improperly by another company? Yes. Did I recommend replacing it? Yes. Will the facilities company approve it? Not sure. Did I cover my ass…. Yes
I wouldn't always blame the last contractor up there, as it could very well be an compound issue involving the power co. or electrician that flip-flopped it anywhere along the line doing repairs. that is eaxctly what you get with bad labeling/phase tagging. seen it before plenty of times and heard nightmare stories far beyond. you just never know anymore.

Pulley sets the speed at which the wheel spins. The outer sheave can be turned to spread them further apart or closer together.

I agree replaced that motor. adjust tension on it means you'll just be back to replace the motor a little bit later than now.

Thanks!
Possibly when drier was removed the line still had some vapor and oil in it and coated the coil. The oil stain is right where the drier is .
Possibly but that’s a double coil and it would have had to penetrate through both, its probably a tiny leak that has been there a while

Love how the tech…. Not sure but going to recommend this and that.. what’s a couple hundred dollars if it’s not yours.
Facilities companies approve what they want, so I recommend repairs. How would you do it buddy

Wonder if it's the same company that likes to bypass limit switches?

5:25 - Better get that fan belt package out of there so it does not get sucked into the blower!
Yeah I saw it jumping around in there 🤣
Oil might be when they replaced the Filter.
I don’t think so, I’ve worked on a ton of these and have never had oul just spray out all over the coil when I removed it.

How can I be a service tech like you man my company doesn’t teach me anything
Invest in yourself and take the time to learn on your own, it will pay off!
I keep those plugs too lol
Hell yeah, bypass plug gang
That’s how Hughes do it
Love that! Thanks for watching!
Instead of removing the covers, use your voltmeter and check for voltage or continuity? Lol
Yeah, I agree on that!
How you make bypass flug . Or how I can buy it Sir?
Carrier usually has one in the unit.
Changed a compressor because it wouldn’t come on. lol😂

Something is blowing those fuses, they rarely just go bad, compressor, motor, wiring….something is wrong.

Possibly bad Capacitor (Easy & cheap fix), Everything else would require more work & cost $$$

that is eaxctly what you get with bad labeling/phase tagging. seen it before plenty of times and heard nightmare stories far beyond. you just never know anymore.
Someone replaced the contactor 2 days before I was there and it wasn’t phased correctly at the blower contactor.

Vapor saturation temperature for sure but I find it hard to believe that high head pressure doesn’t concern you.
