Heat pump repair in Los Altos: what we fix

Heat pumps have a few components that ordinary air conditioners do not: a reversing valve, a defrost board and sensor, and on newer units an inverter compressor and electronic expansion valve. We carry diagnostic tools for all of them. Common repairs include reversing valve solenoids, defrost sensors, contactors and capacitors, refrigerant leak repair, outdoor fan motors and inverter boards.

They sealed and repaired our attic ducts and the back bedrooms are finally the same temperature as the rest of the house. Should have done this years ago.

Called at 10 pm on a Saturday with no heat and someone actually answered. The furnace was running again before midnight. Cannot recommend them enough for anyone in Los Altos.

Heat Pump Repair in Los Altos: frequently asked questions

Why is my heat pump blowing cold air in winter?

It may be in a normal defrost cycle for a few minutes. If it continues, the reversing valve, refrigerant charge or defrost control needs attention.

Do you repair ductless mini split heat pumps?

Yes. We repair Mitsubishi, Daikin, Fujitsu, LG, Gree and other ductless heat pumps throughout Los Altos.

Is it normal for a heat pump to run all the time?

On very cold or very hot days, longer run times are normal for inverter systems. Constant running with the house never comfortable is not, and it is worth a service call.
