Performed air conditioner tune up on 15 year old Goodman unit. System was undersized for the home and was extremely noisy. Client had a dual zone system with a single stage 5 ton furnace and a 3.5 ton air conditioner. Ideally would have two stage equipment for better home comfort. Client would like to upgrade system and add solar to reduce energy bill of $300-$350 a month

Performed air conditioner tune up on 19 year old Carrier in Somerset Brentwood. System is working and in decent shape. It is however no longer as efficient as it once was. Client mentioned high energy bills, system is the likely cause. It is using more energy as it works harder the older it gets

Performed tune up on air conditioner, checked filter, cleaned outdoor unit. Checked capacitors, contactor, electrical connections, refrigerant levels and amperage draw on compressor, condenser fan motor and blower. Evaporator coil dirty, blower motor leaking oil, blower capacitor out of spec and motor at max allowed power usage. Dual run capacitor out of spec, contactor burnt and pitted, compressor uses higher than manufacturer allows power on start up. Outdoor coil starting to deteriorate causing massive decline in efficiency as well as added stress to compressor.

Performing precision tune up service on 2002 York condenser. System runs but struggles to keep home cool on hot days. Another company has been coming out to put refrigerant in over the years. Discovered that the evaporator coil was completely compacted with debris which was blocking the airflow and is likely the cause of the refrigerant leak. Client understands that R22 is going away and that replacement would be the safest option at this time. Cleaned coil, clients are now Certified members!
