Sexton Heating & Air Conditioning | HVAC Repair & Service in Colfax, NC

This is a common issue in our area, often caused by a failing AC capacitor. The capacitor provides the initial jolt of energy to start your compressor and fan motors. Over time, especially with our summer heat, capacitors can weaken and fail, causing your system to draw too much power and trip the breaker. Our technicians can quickly test and replace a faulty capacitor to restore safe, reliable cooling to your home.

If your heat pump is stuck in cooling mode, the most probable culprit is a malfunctioning reversing valve. This valve is essential for switching your system between heating and cooling cycles. Issues like electrical failure, mechanical sticking, or refrigerant problems can prevent it from shifting. Our experts specialize in diagnosing and repairing reversing valve problems, a frequent repair need for Colfax heat pumps, to restore proper heating function.

Certain problems require prompt attention to prevent further damage or a complete breakdown. You should call for immediate repair if you hear loud grinding or banging noises, smell burning from the unit, see ice on coils, have no airflow, or if the system is constantly cycling on and off. For more subtle issues like a gradual decline in efficiency or a minor change in sound, scheduling a maintenance visit is appropriate. When in doubt, give us a call—we'll help you determine the best course of action.
