Is there a way that one (homeowner or HVAC Professional) could determine if one's AC Compressor is working correctly (outside unit). I just had an HVAC contractor replace my Evaporative Coil inside the Air Handler (inside Unit). He pressure tested it for leaks with nitrogen, filled the system with brand new R-22 Freon and then tested the AC. Though there is colder air (65 degree F) coming out of the registers, the suction line does not get cold (to the touch). My other AC unit's (which works really well) suction line gets really cold, and even sweats since it is so cold. The contractor mentioned that the compressor or pump may not be operating properly. He told me to shut off the AC for a few hours and turn it on again. I did that. The suction line is still not cold. Is there a definitive way that a homeowner or HVAC Professional can determine if the compressor/pump is working properly?
