Found unit compressor locked out on thermal lock out due to start capacitor failing and run capacitor starting to go out of range. Recommend replacing both at same time. System compressor needs to cool, will return tomorrow to complete repair and test system. Pulled unit outdoor disconnect to allow system to cool. Replaced run capacitor, start capacitor, and potential relay. Checked compressor operation by manually pushing contactor in. System will work now with a call for coolung.

Found system thermostat programming caused thermostat not to recognize outdoor unit. Reprogrammed thermostat and then cycled system to check operation. Everything came on normally and is working within manufacturer's specifications.

Tried to find the clunking sound when the system turns off, we cycled the system on and off 10 times. Found sound not coming from air handler. It sounds like it’s coming from the heat pump section possibly the refrigerant equalizing. Not much we can do about that.

Performed cooling tune ups on all 3 systems checking all electrical components, refrigerant balance, unit start up, operation, shutdown, cleaning of indoor and outdoor units and treatment of drains. Customer complaint of high power bills in winter. Checked systems in both heating and cooling and found system draws about 30-40% more power in the heating mode. 2006 r-22 downstairs unit is doing the most of the electrical draw in heating mode at 8.8 amps @ 70° outdoor temperature. Replacement of downstairs system could see a reduction in power consumption.

Found no low voltage. When tstat was replaced the transformer shorted because the air handler has no fuse Replaced transformer tested system from thermostat. Something was shorted out in the thermostat not allowing the heat pump to come on. Replaced it with a Honeywell T6 thermostat. Tested operation no other issues found.

Found noise happens when system shift into defrost. Goes away after a minute when refrigerant is moving in opposite direction noise also happens when shifts back. Nothing can be done as this system didn’t have quite shift option Checked capacitor while I was in the electrical compartment

Noise may have been when it was in defrost. I didn’t hear anything when the unit was running. All I did was listen so I’m not gonna charge for this.

123 Kent street Tested r22 refrigerant charge. Tested heat strip. Heat pump operation checked electrical connections and tstat. Compressor is drawing 7.2 A condenser fan is drawing .8 A Heat pump had a 25° temperature difference Heat strip had a 18° temperature difference 64/262. Suction line temp. 148°. Outdoor temperature 47° Everything seems to be running as designed. I can’t find anything wrong. Not sure what would be causing a high electric bill. Besides the ductwork being poorly designed.

Added SS to safety condensate switch. Mark BTUs on air handler door and also Mark data plate for the heat strip and marked KW‘s on the air handler door.

Mark KW‘s on the door marked data plate on air handler and wrote 1800 BTUs on air handler. Added SS2 condensate float switch. Put light fixture back on screw.
