Performed diagnostic on 12 year old Carrier air conditioner. Not blowing air inside. Outdoor unit was running. Not cooling the home. Blower motor has seized due to heavy debris build up in the system from not changing filters. Cleaned system, replaced blower motor and a few smaller parts on the AC. Unit is running well now. Client joined maintenance program.

Performed tune up on air conditioner, checked filter and cleaned outdoor unit. Checked capacitors, contactor, electrical connections, refrigerant levels and amperage draw on compressor, condenser fan motor and blower. Added two pounds R22 per tune up special, refrigerant levels were at 175 and 25 at 85 degrees outside. Metering device installed improperly causing system to not operate correctly. Also found dual run capacitor below manufacturer specifications and contactor burnt and pitted. Blower motor at max allowed amperage draw and blower capacitor below spec. System operating upon completion but not well, clients looking at repair vs replacement options

Performing AC tune up service on 2000 York condenser, system runs but has been tripping the breaker and not keeping up with the heat when it hits 90+ degrees. Diagnosed failing blower capacitor and overamping compressor motor. Replaced capacitor and cleaned up furnace, added a hard start kit to lower compressor amperage and balanced refrigerant as part of the tune up service. Noticeable difference in cooling and noise level. System is running much better now!
