Spotlight on UVC in HVAC

Ultraviolet light C band (UVC) devices installed in the AC system are being used increasingly to eradicate surface and airborne mold, as well as viruses and bacteria. The devices eliminate the odors associated with mold, mildew and VOCs by cleaning the AC coils where they are installed. On existing systems, the best results are obtained when UVC light is located downstream of and facing the cooling coil. It’s important to avoid installing devices in the return air ducts.
