Yes, this is often a sign of a failing reversing valve, a common issue with our local heat pump systems due to year-round use. The valve is what switches your unit between heating and cooling modes. Our technicians can diagnose this quickly and perform the precise repair to restore full functionality to your system.

Absolutely. For Martinsville homeowners, seasonal maintenance is key. A professional tune-up cleans critical components, checks refrigerant levels, and ensures your system operates at peak efficiency. A neglected system can use 10-25% more energy. Our maintenance service helps catch small issues before they become major problems that spike your utility costs.

For our climate with both hot summers and cold winters, we recommend setting your thermostat to a consistent, moderate temperature (like 78°F in summer, 68°F in winter) and using programmable settings. Also, ensure your air filters are changed monthly during peak seasons and that your outdoor unit is kept clear of debris. Proper insulation and sealing duct leaks are other local fixes we often recommend to prevent wasted energy.
