2nd call today, "not cooling well" at an eye doctors place.
Climb up on the roof and see a whole row of these dinosaurs. The water is from me cleaning the condensor coil on the one I'm working on.
Looks like its on at least its 2nd compressor. Bubba didn't bother to line up the mounts with the studs sticking up out of the bottom of the unit. The "new" compressor has been going strong for at least 20 years though...
The run cap bandit has been here, well, maybe his father anyway. That thing has been hanging there taped to the wires for a long LONG time. They just don't make good duct tape like that anymore!
Something they don't prepair the kids for in tech school. Systems that normally operate at condensing temperatures 45º-50º above ambient.
Once I cleaned the condensor coils the head pressure dropped from around 450 psig to something more consistant with operation at 90º outdoor and 75º indoor temperatures.
Ok, well lets just say that "normal" is a relative thing. In this case, 330 psig is "normal" on a 90 degree day for one of these 43 year old dinosaurs.
This is a brand I hadn't seen before. It is the 2nd newest unit on the roof, I assume it is from sometime in the late 60's to early 70's.
Who made "Twin-Air" brand equipment?
I didn't take a picture, but the newest unit on the roof is a POS Carrier that was installed about 2 years ago. I would be willing to bet that it will die before the last of the 1962 vintage Fedders units dies.
