HVAC Repair Chattanooga TN | Call Apex Heating & Air Conditioning

This is often caused by a faulty reversing valve, a common issue with our local climate's demands. The valve directs refrigerant flow for heating or cooling mode. When it sticks or fails, your system can't change functions properly. Apex's technicians specialize in diagnosing and repairing or replacing these valves to restore your heat pump's full functionality.

Key signs include reduced cooling or heating output, longer system run times, ice on coils, and a noticeable hissing sound. In Chattanooga's humidity, a leak also makes it harder for your system to dehumidify. If you suspect a leak, call Apex promptly. We'll locate the leak, repair it, and safely recharge your system to the manufacturer's specification.

Our local climate puts extra strain on systems. Regular professional maintenance from Apex includes checking refrigerant levels, testing the reversing valve operation, cleaning coils, and ensuring all electrical components are secure. This proactive care catches small issues—like a sticky valve or a slow leak—before they become major, costly repairs, keeping your system efficient and reliable.
