STONE'S HEATING AND AIR - Chattanooga's Professional HVAC Services

The most telltale sign is your AC running constantly but not cooling your home effectively, especially during our humid summers. You might also notice ice forming on the refrigerant lines or coils, or a noticeable hissing sound from the unit. Since refrigerant leaks are a frequent issue here, it's best to call for professional diagnosis and repair promptly to prevent further damage and restore efficiency.

Regular professional maintenance is key to fighting high energy costs in Chattanooga. Our tune-up includes cleaning coils, checking refrigerant levels, calibrating thermostats, and ensuring all components are working in harmony. A dirty or slightly misadjusted system can work 10-20% harder, directly increasing your bills. We help your system run at peak efficiency, so it uses less energy to keep you comfortable.

It depends on the age and condition of your system. A sudden spike often points to a specific, repairable issue like a failing component or a refrigerant leak—common problems we see locally. For systems over 10-15 years old, however, newer, high-efficiency models can offer such significant savings that replacement becomes the more cost-effective long-term solution. We provide honest assessments to help you make the best financial decision for your home.
