Winston-Salem HVAC Repair | Heat Pump & Thermostat Experts | Chappell Heating & Air

This is often a sign of a failing reversing valve, a very common issue with our local heat pumps. The valve controls the refrigerant flow to change modes. Our humidity and temperature swings can cause it to stick or fail. A Chappell technician can diagnose the valve, perform a repair if possible, or recommend a replacement to restore your system's full functionality.

Absolutely. Thermostat malfunctions are a frequent culprit for uneven temperatures in Winston-Salem homes. The issue could be incorrect calibration, a bad sensor, wiring problems, or simply an old unit that can't communicate properly with your HVAC system. We'll test your thermostat's accuracy and connection to diagnose the real problem, ensuring it correctly manages your heating and air conditioning for consistent comfort.

Proactive, bi-annual maintenance is key. For heat pumps, a spring and fall tune-up allows our technicians to check the reversing valve's operation, clean coils, test refrigerant levels, and calibrate your thermostat under real-world conditions. This service catches small issues—like a sticky valve or a drifting thermostat sensor—before they lead to a complete breakdown, saving you money and discomfort, especially during our peak seasons.
