Multiple NO A/C Service Calls!!!

A few service calls and ended the day with a very odd compressor replacement. I couldn't for the life of me understand why I was getting what I was getting....unit seemed to be operating well but my pressures would tell me something else. Let me know if you think I made the wrong call on adding more refrigerant of if I should've added more than I did!!

I love the approach to troubleshooting and getting the apprentice to develop good work habits. NO BAGS ON THE CONDENSER!!!

Love your videos, guys. The one thing I noticed is that don't forget to change filter drier when open to environment. But great content, bud

first one, The empty house. I think a check on the condenser would be necessary second one with the Rheem, Looks like low charge. subcooling is usually around 10 degrees and that one was at 2 third one the Goodman. I think The Filter drier is clogged. The goodman filter drier is inside the condenser. Are you sure it has a piston? probably a txv. thanks for the videos.

Changed a compressor but not filter drier then has issues….hmmm I think I change out filter drier to not have that as another restriction

put a 3/4 hose cap on your pump discharge to prevent it from spilling in your truck

HEY man dont sweat forgetting the 24v and possible tripping/blowin a fuse... shit happens, its alot going on. one time i discharged a cap and forgot to turn the power off on this Bryant rtu

No new filter drier on a burn out compressor replacement? You will probably be back to replace a plugged drier

If the coil is under positive pressure a trap is not needed(blower pushing are through evaporator coil) if the coil is under negative pressure(blower is pulling through air through coil) like most downflow units and air handlers than a trap is needed if not the blower will pull air through the condensate pipe outside and air lock the drain pan. Causing water to overflow in the evaporator drain pan. From my knowledge thats what I’ve always been told

@AB_HVAC 28 күн бұрын

That's what I've been told too, but in rare instances, I've found a few upflow positive pressure drains needed a P-Trap. Not sure if it was a static pressure issue, but I know once that P Trap was on it the system began draining

@numchux2 2 ай бұрын

Looks like someone mixed R22/410A on that last system...the R22 doesn't evaporate at the higher suction pressure and it causes this. I could be wrong, but makes sense.

@AB_HVAC 2 ай бұрын

I've never come across something like that before. For more context, the air handler is in spacious closet, sitting on a return plenum with a "grille" opening of about 16x16, the closet also has louvers. So I was under the assumption it needed a bigger return. My boss would say it's been working all this time but in my head, I wonder if that's what helped kill this prematurely. House is also zoned for upstairs and downstairs

@AB_HVAC well compressors are slowly dying the day you start using them tbf...the windings are literally trying to burst away from eachother each startup 😆

@redneckways1617 2 ай бұрын

I’m guessing the trap is on the outside on that first unit?… If so then both of those lines have to be capped for the negative pressure drain to drain properly

@AB_HVAC 2 ай бұрын

You'd be correct about the negative if that WASNT a split gas furnace. The drain is under positive pressure on that first one, and to my knowledge, not all positive drains need a trap.

Seems like an obvious restriction. And my guess would be the filter drier. Did you replace it? Did you check it? Video is edited so not all steps are on camera.

@AB_HVAC 2 ай бұрын

No I was instructed not to because it originally didn't pose any issues (yes I understand it's best practice but im not gonna buy something for the job my boss says to not get). In my experience, a restriction pulls down on the suction pressure and increases the head pressure. My best guess was I should've pulled a deeper vacuum maybe. And that's not to say that the filter dryer couldn't be an issue, I just didn't think that from my readings at the time

@Mo4Honesty 2 ай бұрын

@@AB_HVACincreased head pressure is another name for stacking refrigerant on the condensing unit. Adding refrigerant charge to reduce the superheat will INCREASE the evap pressure, which implies you think it was too low before. That's exactly how you just described a restriction. You already have plenty of refrigerant based on SC but it's not all getting through. OR.... maybe the piston is the wrong size or has crud in it?

@AB_HVAC 2 ай бұрын

Yeah I get that, guess what I mean to say is I've always seen a restriction steadily drop suction pressure while increasing head. Where as at the end of the video had fairly high head, and a suction pressure that wasn't dropping. Could that still be a restriction?

@Mo4Honesty 2 ай бұрын

@@AB_HVAC yes, it could. Think of a water pipe with a slight blockage vs severe blockage. If you flood the opening with water, both cases will back up eventually, but the partial one will not be as noticeable. Or an air filter. Do you think a clean filter, half dirty filter and totally caked filter all have the same static pressure?
