Heat Pump Repair & Replacement

A heat pump fails differently than a standard AC, and the fix depends on which mode broke. If your system cools fine but blows cold in winter, the reversing valve or its solenoid is a common suspect. If it stopped cooling entirely mid-July, we check the compressor, the run capacitor, and refrigerant level first — the parts that give out fastest under sustained Phoenix load. We diagnose before we quote so you know whether you're looking at a part swap or a bigger decision.

Repair usually wins when the unit is under about 10 years old, the compressor is healthy, and the failed part is a capacitor, contactor, motor, or valve. Replacement makes more sense when the compressor has failed on an older unit, the system uses discontinued R-22 refrigerant, or repair costs approach half the price of new equipment. We lay out both numbers so you can choose — we don't push a replacement to skip a repair we can actually make.

Desert conditions shape what we find. Attic and rooftop units in Maryvale and Laveen take direct sun and heat-soak that accelerate capacitor and contactor wear. Older homes in Willo Historic District, Encanto-Palmcroft, and Coronado often have undersized returns or aging line sets that affect how a heat pump performs — worth checking before you assume the compressor is the problem. Homes near South Mountain in Ahwatukee and up toward North Mountain and Sunnyslope see enough winter heating demand that a bad reversing valve gets noticed fast when mornings turn cold.

We service heat pumps across Arcadia, Desert Ridge, and the rest of Maricopa County, whether it's a single failed part or a full changeout. When your house is climbing past 90 inside on a 110°F day, that's an emergency, and we treat it like one. AC out? We're on the way — call (602) 774-2910.
