I am an auto mechanic and work on a/c all the time. I own a

Hello, I am an auto mechanic and work on a/c all the time. I own a True Manufacturing double door cooler model GDM-35. It's an older unit and we've had to ad Freon to it every few years. It's that time again and it's been so long I've forgotten which of the lines is hi side and which is low side. I've pulled the compressor rack out of the unit so I can easily get to both hi and low sides. I need to know a few things. Remind me which is the low side? Is it the line that comes directly out of the top of the compressor or the line that is down stream of the condenser? I know enough to add the R-134a to the low side but do I hook up to the low side with the compressor running or turned off? Also when disconnecting my gauges from the low side hook up should the compressor be running or off? Also the sticker on the inside of the unit says low side pressure 140. Is this psi? This sounds like a very high pressure for the low side? Thanks for any help you can provide. Jack

ICP PHD460000KTP0D1 issue (you helped me 2 years ago). After

ICP PHD460000KTP0D1 issue (you helped me 2 years ago). After not using the system all winter, the ac / blower would not turn on. I suspected a wiring issue due to critters, so I moved the tstat outside and spliced it in. Blower works, but I am not getting cold air - only hot (again)! This is strange because nothing has changed (or maybe I screwed up something). Also - It seems I am getting COLD refrigerant into the condensor coils above, but HOT going to the evaporator coils underneath? Is there a valve that is stuck? :-| Anyhow - I have a CAT5 cable for the tstat and I'd like to hook up the wiring so all the functions are available as you suggested 2 years ago.

I just had a York evaporator coil replaced. The AC unit is less than 2 years old. The people told me that the part was covered, but labor wasn't. I was just charged $1900 to replace a warrantied part, and that seems extremely excessiveJA: Did you double-check the thermostat? And what about the unit's filters?Customer: all the filters are replaced every 3 months. The technicians checked all of that and did a leak test on a previous visit, where they discovered the leakJA: Do you plan on doing the work yourself?Customer: nopeJA: Anything else we should know to help you best?Customer: I don't think so

I have an old Rheem 36,000 btu Central A/C system Model

I have an old Rheem 36,000 btu Central A/C system Model RACC-036JAS built in 1990, it has always worked flawlessly and turns our 1,800sf single-level home into a refrigerator...my wife says we should replace it as it could die any time, we live in Portland, OR, so it gets used like 90-120 days a year? How long can this thing last, I have it serviced every year? I find the new systems may be more efficient, but these old systems seem to last forever? What's your take?
