UV lights for furnaces are germicidal lamps installed within ductwork or near the evaporator coil to help eliminate mold, bacteria, and viruses circulating through your HVAC system. By preventing microbial buildup on coils and internal components, UV lighting improves indoor air quality, enhances system efficiency, and supports long-term HVAC performance. Professional installation is required, and UV bulbs typically need replacement every one to two years to ensure continued effectiveness.
