Performed furnace tuneup on three-year-old Trane high efficiency system. The unit was in good shape with no dust buildup. Cleaned out sensors and tightened all wire connections. Client purchased a lifetime washable filter so that he would not have to buy them regularly. He also joined our maintenance program to have his unit looked at twice a year to guarantee peak performance

Performed air-conditioning tuneup on 11-year-old carrier. The unit was noisy on start up, and customer had concerns with unit keeping up with calling the house. Found that the unit had too much refrigerant, removed excess which should help with insufficiency. Also added a hard start kit and reduced starting amps by 66 Amps, helping systems start more easily while saving some energy. Replaced blower capacitor to prevent premature motor failure. Joined maintenance program to ensure system reliability
