David was honest, knowledgeable and technically sound.
Performed AC diagnostic on 1989 condensing unit. Upon my diagnostic I found that the condenser fan motor was running although compressor was not and then proceeded to open up the service panel and found that the battery cap hermetic side terminal was blown. Replaced battery cap And Compressor became Energized. Measured refrigerant pressures although system did contain our 22 band Freon pressures were adequate with 59Â° supply temp when indoor temperature was 87. Recommended that compressor Is replaced if they want to stop experiencing intermittent behavior because once I was done and the new battery cap was in the compressor did fail on thermal overload. This compressor is a failing compressor and will completely not work soon. Also recommend a compressor starter kit to reduce lock rotor amps on start up and then high-voltage relays replaced due to high amounts of pitting on contact point. Upon departure system was running although itâ€™s going to be intermittent due to the windings on
Upon arrival performed maintenance. Hooked up refrigerant gauges to system, noticing system was low on refrigerant, system was at -7 subcooling, looked inside of system for any oil traces. Added 4lbs of r-410a refrigerant w/ leak dye & seal. System is now at a 6 subcooling with a 20 degree temp split, air coming out at 51 degrees. Secondary motor control good. Motor good. Opened up system and washed coils with water. System was reset tested and fully functional upon departure. Scheduling return visit to look for Leak.
