Brittany B.
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.
