Alaskan Air Conditioning & Heating

What this contractor is listed for

Control boards manage low-voltage circuits that signal contactors, compressors, and blowers to operate in sequence. A wire connection had loosened on the relay terminal, breaking the signal path to the outdoor unit. The system powered on and ran the blower, but the compressor never received its start signal. Our technician traced each wire from the thermostat through the board, located the loose terminal, and secured it properly. The outdoor unit fired up immediately after reconnection. This Phoenix homeowner now has full cooling restored. Give us a call if your system runs but doesn't cool the house.
