Benefits and Drawbacks to UVC HVAC

Pluses of UVC emitters: • Easy to install, maintain and operate. • Stop mold growth on coils and eliminates the spread of mold spores and mycotoxins in the occupied space by the air-handling system. • Clean coils by constantly killing mold; manual cleaning or chemical processing is only a temporary solution to mold growth on coils. • Does not produce ozone, and eliminates the need to use coil cleaning chemicals, which are released into the airstream. • Improves airflow, reducing energy costs via reduced fan energy. • Cleans coils so that they perform better, resulting in energy savings. • Coil cleaning is substantially reduced or eliminated saving labor and chemical costs. • Occupant health may improve resulting in less sick time and increased productivity. Minuses of UVC emitters: • There are many anecdotal stories supporting the use of UVC in mold prevention, but scientific cause and affect data has not been made available yet. • UVC users may not replace lamps at end-of-life resulting in loss of protection. • UVC emitters are not required by code or law.
