DeHart Air Conditioning: Local HVAC Services Serving Duncan, OK 73533

This is a common issue in our area. It could be a faulty thermostat sensor, wiring problems, or incorrect calibration. Our technicians will diagnose the specific cause—whether it's a simple battery replacement, a recalibration, or a more complex electrical issue—and provide a clear, upfront solution to restore precise temperature control in your home.

First, check your circuit breaker and air filter, as a clogged filter can cause the system to overheat and shut down. If those aren't the issue, the problem could be a failed capacitor, a faulty motor, or a relay switch. Don't delay—a non-functioning fan can lead to further system damage. Call us for a prompt diagnosis and expert repair to get your air flowing again safely.

Regular maintenance is key. We recommend bi-annual tune-ups (spring and fall) to clean components, check refrigerant levels, inspect electrical connections, and ensure your thermostat is calibrated. This proactive service helps catch small issues—like a weakening capacitor or a dirty sensor—before they turn into major repairs, saving you money and preventing unexpected breakdowns during extreme weather.
