White's Heating And Air Service - Charlotte's Trusted HVAC Services

Common signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing sound, and a sudden spike in your energy bills. Refrigerant leaks reduce efficiency and can cause compressor failure. If you notice any of these issues, it's best to call us for a professional diagnosis and repair to protect your system.

This is often caused by a faulty reversing valve, a key component that switches your heat pump between heating and cooling modes. When it fails, your system gets stuck. Our technicians can test the valve's solenoid and check for electrical issues to determine if a repair or replacement is needed to restore proper function for our variable NC seasons.

We prioritize emergency calls, especially for issues like complete system failure or refrigerant leaks that leave you without heating or cooling. We offer same-day or next-day service for most urgent repairs in the Charlotte area. When you call, we'll assess the situation and provide you with a clear timeframe to get your comfort back on track.
