R E Heat And Cooling: Qualified HVAC Services Serving Fairfield, AL 35064

This is a very common issue in our area. Often, the problem isn't with the thermostat itself but with incorrect wiring during installation or a compatibility issue with your existing HVAC system. Our technicians will first verify the wiring at your furnace or air handler, ensure the correct 'C' wire is providing constant power, and then check your system's compatibility with the smart thermostat model. We get you reconnected and in control quickly.

If your heat pump is blowing cool air when set to 'heat' or warm air when set to 'cool,' a faulty reversing valve is a likely culprit. You might also hear a hissing noise from the outdoor unit. This valve is critical for switching between heating and cooling modes. Our experts can perform a diagnostic test to check the valve's solenoid coil and internal mechanism to determine if a repair or replacement is needed to restore proper function.

A stuck reversing valve forces your heat pump to run in the wrong mode, putting immense strain on the entire system. This not only leaves your home uncomfortable but can also lead to compressor failure—the most expensive part to replace. Addressing it quickly with our repair service prevents further damage, saves on energy bills from an inefficient system, and protects your investment in your home's comfort.
