Air Supply of Wilmington Heating and Cooling - Wilmington's Certified HVAC Repair

Yes, this is a very common issue in our coastal climate. The AC capacitor, which helps start the compressor and fan motors, can fail due to heat, humidity, and age. A failed capacitor is a frequent cause of a system that hums but won't start or has weak airflow. Our technicians can quickly diagnose and replace a faulty capacitor to get your cool air flowing again, often the same day.

If your system is over 10-15 years old, requires frequent repairs (like repeated capacitor or fan motor issues), has rising energy bills, or struggles to maintain consistent comfort in our humidity, replacement is often more cost-effective. We can assess your current system's efficiency and provide a new, reliable installation tailored to your home's size and our local weather, improving comfort and lowering monthly costs.

Absolutely. A grinding noise often indicates a failing blower fan motor or bearings in the air handler. This is a critical component that circulates air throughout your home. Ignoring it can lead to a complete system shutdown, especially during peak summer heat. We recommend scheduling a repair promptly. Our team can replace the motor or related parts to prevent a breakdown and ensure your system operates quietly and efficiently.
