Big D’s Heating and A/C | Licensed HVAC Repair in Marion, IN

This is often a sign of a faulty reversing valve, a common issue we see in Marion due to system strain and normal wear. The valve directs refrigerant flow to change modes. If it's stuck, your system can't heat or cool properly. Our technicians can test the valve's solenoid and pressure, performing a precise repair or replacement to restore your heat pump's full functionality.

Air handler fan failures are frequent in our area, often caused by a bad capacitor, a worn-out motor, or a tripped safety switch from overheating. Don't ignore it—a non-functioning fan stops all heating or cooling. Big D's will safely diagnose the root cause, whether it's a simple capacitor swap or a motor replacement, getting your air flowing again quickly and efficiently.

Proactive, seasonal maintenance is key. Our local tune-up includes cleaning coils and checking electrical components to prevent overheating that leads to fan failure. We also inspect refrigerant charge and test the reversing valve operation to catch small issues before they leave you without heat or AC. Regular service from a local expert like Big D's extends your system's life and improves reliability.
