Yes, a refrigerant leak is a common cause of poor cooling. Beyond making your system inefficient, it can damage the compressor and is harmful to the environment. Our Malden-based technicians can safely locate the leak, repair it, and recharge your system to the manufacturer's specifications, restoring both performance and efficiency to your home's AC.

The best protection is annual professional furnace maintenance. Our technicians perform a comprehensive safety check, inspecting the heat exchanger for cracks, ensuring proper venting, and checking for any combustion issues that could lead to CO production. We also strongly recommend installing CO detectors on every level of your home. This proactive approach is crucial for safety in our local community.

Our preventative maintenance tune-up is designed to catch small issues before they become big, expensive problems. We clean critical components, check refrigerant levels and pressures, inspect electrical connections, test safety controls (including those that prevent CO risks), lubricate moving parts, and ensure your system is operating at peak efficiency for the New England seasons ahead.
