HVAC Repair Cornelius NC | Call Davidson Air Conditioning Co

This is a classic sign of a failed AC capacitor, a very common issue in our area due to frequent power fluctuations and high summer demand. The capacitor is like a battery that helps your outdoor unit's motors start. We can quickly diagnose and replace it to restore your cool air promptly.

This often points to a problem with the heat pump's reversing valve, a key component that switches the system between heating and cooling modes. When it gets stuck or fails—a frequent issue here—your system can't produce heat. Our technicians are experts at testing and repairing or replacing reversing valves to get your warmth back.

Proactive, bi-annual maintenance is the best defense. Our tune-ups include checking capacitors for bulging or weakness, testing the reversing valve operation, cleaning coils impacted by local pollen, and ensuring proper electrical connections. This care helps catch small issues before they lead to a breakdown during our hot summers or chilly winters.
