I performed a single system cooling maintenance on on a gas heating system. I checked amps, capacitors, filter, electrical, safeties, cleanliness, refrigerant temperature, and temperature differential. I found the compressor capacitor was reading .2/50. This indicates that the compressor has been start and running with the hard start kit. This is extremely bad for the compressor. I found the blower wheel to be filthy and the capacitor for the blower motor to be worn. The capacitor is reading 9/10. This is out of manufacture specifications. I replaced the 50mfd capacitor, provided pricing for blower cleaning/capacitor, and pricing for a new 4 ton American standard gas complete 14 seer.
