In 1903, Niels Finsen won the Nobel Prize in Medicine for his use of ultraviolet light in the treatment of tuberculosis.
Since then, ultraviolet lights have been widely adapted for all kinds of uses: sterilizing hospitals,
sterilizing water,
germicidal lamps in food establishments, and even curing nail polish faster. If UV light is so effective, how can it be applied to
improving indoor air quality for residential HVAC systems? Will it kill mold and bacteria in HVAC systems? Yes,
but you need to understand the priorities of indoor air quality and the types of UV lights available for residential HVAC systems.

About 2 years ago, we installed a 19 SEER Lennox XC 21 air conditioner. During our most recent AC service, the technician also
installed a FREE COOL HVAC UV light inside the air handler, which remains turned on 24/7. According to the technician,
HVAC UV lights are very effective at controlling mold inside the air handler. All mold in line-of-sight of the UV bulb will be killed,
keeping the coil mold-free. He also mentioned that several clients with respiratory problems are even able to tell if the UV bulb has
burned-out due to reduced air quality. I’ll let you know if I am able to tell.
