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
Performed AC diagnostic on 13 year old Carrier. Unit had a failed dual capacitor. Replaced and ran tested system. Everything else checks out well
Performing annual maintenance on 1985 Day & Night condenser, system runs but has been popping the breaker on hot days. Discovered the compressor motor to be overamping and made recommendations for repairs. Checked refrigerant levels and cleared out a very dirty drain line. System is running. Providing estimates to replace the system and ductwork, possibly also adding solar panels. Client has awesome kids that are super cute and very eager to share toys. Definitely enjoyed this call, thank you!
Performing AC diagnostic service on 2011 Goodman condenser, system runs but is not able to cool the home at this time. Looks like previous owner replaced condenser and left 1988 furnace and coil. Hooked up refrigerant gauges and discovered that system has major leak, all refrigerant has leaked out (R22). Clients decided to move forward with system replacement and we will be installing a brand new system very soon, we look forward to keeping clients comfortable for many years to come!
