Do your air ducts contain mold? Do you or your family suffer from serious allergies? Are there indoor air quality issues in your home?
If so, installing an ultraviolet light in your HVAC air handler to kill microbes as they pass through the system may be the solution you are looking for.
An HVAC UV light appears as a small external box attached to your air handler or ductwork. UV lights can help prevent allergens in your HVAC system

How HVAC UV lights work
UV lights are effective, but they work in a specific range. They’ll kill organic growths, such as mold or bacteria, but they have no effect on dust, pet dander or other allergens. In most residential cases, an HVAC company will install the UV light near the coils to prevent mold or bacteria growth as air passes through. Since all of the air passes through the coils, this also kills growths in the air. UV lights are particularly effective in humid climates, where evaporator coils can easily get wet.
