Ultraviolet germicidal irradiation (UVGI) is a proven technology that uses short-wavelength UV-C light to destroy mold, bacteria, viruses, and other biological contaminants in your HVAC system. These harmful microorganisms thrive in the dark, moist environment inside your ductwork and on your evaporator coil, and they're constantly circulated throughout your home every time your system runs. Mark's Heating & Air Conditioning installs professional-grade UV light systems in homes across Sparta, TN and the surrounding Upper Cumberland communities.

UV lights are typically installed inside your air handler near the evaporator coil, where they work continuously to sterilize the air passing through your system. This not only improves your indoor air quality but also keeps your evaporator coil clean, which improves system efficiency and reduces the need for coil cleaning. Some homeowners also choose to install UV lights in their return ductwork for additional air purification.

If you're concerned about mold growth in your HVAC system, suffer from allergies or respiratory issues, or simply want the cleanest possible air in your home, UV light treatment is an effective and affordable solution. Our technicians can install a UV light system during a routine maintenance visit, and the bulbs typically only need to be replaced once a year.
