Protech Hvac Services | Top-Rated HVAC Repair in Chicago, IL

Yes, refrigerant leaks are a common issue in our Chicago climate, especially with older AC units. Our technicians use electronic leak detectors to precisely locate the source. We then repair the leak, evacuate the system to remove moisture and air, and recharge it with the exact amount of refrigerant specified by the manufacturer. This restores efficient cooling and prevents further damage to your compressor.

Absolutely. Many Chicago homes, especially in historic neighborhoods, have ductwork that has settled, become disconnected, or developed gaps over time. We perform a thorough duct inspection and use specialized sealants and tapes to seal leaks at joints and seams. Properly sealing your ducts can significantly improve comfort, reduce dust, and lower those high heating and cooling bills you're experiencing.

Our comprehensive maintenance visit is designed to catch issues like small refrigerant leaks and early signs of duct problems before they become major. We check refrigerant levels and pressure, inspect the coil and drain line, examine accessible ductwork for leaks or damage, clean critical components, and ensure your system is running at peak efficiency to handle Chicago's hot summers and cold winters.
