Heat pump repair in Diamond Bar: 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.

Furnace kept shutting off every few minutes. They found a dirty flame sensor and a clogged filter, cleaned both, and it has run perfectly since. Quick and affordable heat pump repair.

Two other companies told me I needed a whole new system. These guys found a refrigerant leak, repaired it and my 8-year-old unit is cooling like new. Honest people.

Heat Pump Repair in Diamond Bar: 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 Diamond Bar.

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.
