In Livermore at Mr. Gu’s house to provide an estimate for upgrading his standard single stage equipment to a hybrid dual fuel heat pump system. I explained how the equipment operates and discussed the various options for his house.

Performing precision tune up service on 1996 Payne Condenser. System is running but not cooling properly. Diagnosed low refrigerant and possibly failing metering device which is not allowing the refrigerant to move properly at this time. Added 2 lbs of R22 refrigerant to Balance, system is cooling but still showing signs that the metering device is sticking. Made recommendations for further repairs and went over options for replacement.

Performed air conditioner tune up on a 4 year old Carrier. System had no issues other than being over charged. Balanced to the appropriate levels, increasing efficiency. Performed duct inspection and found that the one vent needed to be repaired.

Performed tune up on air conditioner, system operating upon arrival. Checked capacitors, contactor, electrical connections, refrigerant levels and amperage draw on compressor, condenser fan motor and blower. Heat exchanger has thermal stress marks, Evaporator coil rusty with possible crack in pan. Blower motor has been replaced but amperage is still at max. Blower capacitor has been replaced and is within spec, and control board has been replaced. No fused safety switch only light switch. Primary drain does not have a trap or breather. No safety float switch. Condenser leaning to one side because back side has sunk. Compressor amperage very high, condenser fan motor pulling high amps and rusty and noisy. Due to age, efficiency and condition recommend upgrading system. Operating properly upon completion
