Gamma AC & Heating - San Antonio's Best HVAC Services

Yes, a stuck or failed reversing valve is a common culprit for a heat pump blowing cold air when it should be heating. Our San Antonio technicians are experts in diagnosing this specific issue. We'll test the valve's electrical solenoid and check refrigerant pressures. If a repair is possible, we'll perform it on the spot. If replacement is needed, we use high-quality OEM parts to ensure your system operates efficiently through our variable Texas winters.

Uneven cooling in multi-story homes is very common in our San Antonio climate, often caused by ductwork design, insufficient insulation, or an undersized AC unit. Gamma AC & Heating performs a detailed comfort analysis. We check airflow in every register, assess your duct system for leaks or restrictions, and evaluate your system's capacity. Solutions may include duct sealing, adding a zoning system, or adjusting fan speeds to balance temperatures between floors effectively.

We inspect electrical components, clean coils, check refrigerant levels, calibrate your thermostat, and test safety controls.
