Heat pumps are an efficient year-round solution for both heating and cooling, but they require specialized knowledge to repair correctly. At RB HVAC INC., our technicians are trained in diagnosing and fixing all types of heat pump problems — from reversing valve failures and refrigerant issues to compressor malfunctions and airflow restrictions. We also perform seasonal maintenance that includes checking defrost cycles, testing thermostat calibration, cleaning coils, and ensuring proper refrigerant charge. If your heat pump is short-cycling, running constantly, or blowing cold air in heating mode, we can identify the root cause and offer a lasting repair. For older units that are losing efficiency, we can guide you toward a high-performance replacement that saves you money on utility bills. Serving homeowners and businesses across Stockton, we take pride in restoring comfort quickly and affordably.
