My air cond. make Trane is working on 85 psig in an ambient temp. of 29 degrees and the efficiency of both compressor and evaporator is not to the max.
SOURCE: I just installed a GSC140421 using a coil CAPF
hey there, the matching coil for your unit is a Model# CAPF4860C6A. The coil you have installed is a 13 seer where the condenser is a 14 seer. Myy guess at this point without being there is you have a hot house (80 psi suction) while eliminating more heat from the condenser (180 psi). I am also guessing you are using r-22? If you could post your super heat and subcool readings and if ou have a txv or fixed orifice (guessing txv?) I could help you pinpoint the problem.

Expansion valve on the condensor or possibly overcharged with refrigerant?
SOURCE: My heatpump keeps running, but only drops
You have a low refrigerant charge. Your low reading which coresponds to the temp at the coil 49psi is about 20 degrees fr. It should be closer to 70 psi depending on the ambient temp indoors. The coil has to be above freezing I usually shoot for 38 to 40. your sub cooling needs to be at least ten. And if you cant feel the heat leaving throuhg the condenser fan it aint moving it.

It sounds like you are low on charge. I think you have a thermostatic expansion valve and you need to check the subcooling, you should have 12 to 15 degrees at 95. At 95 degrees your head should be about 280# for a 12 or 13 SEER unit or higher depending on the effeciency. At 78 to 80 degrees indoor depending on the humidity, that is normal. The valve will open to try to fully feed your indoor coil and it sounds like your head pressure is to low to force enough refrigerant thru the coil.

Hello, what is your high side pressure? A bad compressor will show abnormally high low side pressure with abnormally low high side pressure. That 45 low side pressure is low And superheat high. If you high side pressure is normal toma little above normal but the low side remains low you have a restriction in the system, that might be why it's not taking in tne freon. Let me know you high side pressure
