AC Heat Pump Repair in Des Plaines, IL

What Heat Pump Repair Involves

Heat pumps are complex systems that switch between heating and cooling, so accurate diagnosis matters more than ever. Our technicians are trained specifically on heat pump operation — we test the reversing valve, defrost controls, refrigerant charge, and auxiliary heat to find the true cause of the problem, whether your system won't switch to heating, blows cold air in winter, runs constantly, or has stopped altogether.

We service all major heat pump brands and configurations, including air-source and hybrid systems. Once we've identified the issue, we explain your options clearly and perform the repair with quality parts — whether it's a failed compressor, a faulty reversing valve, a refrigerant leak, an electrical failure, or a defrost board issue. You'll always know the cost upfront, and we'll never recommend a repair you don't need.
