In Springfield, WV, we installed a whole-home UV light air purifier, specifically the APCO-X by Fresh-Aire UV, in an existing HVAC system. This unit was mounted in the ductwork near the evaporator coil to maximize microbial disinfection. We connected the purifier to the system’s electrical panel using a dedicated 120V circuit and tested it to ensure proper operation. The UV light helps reduce airborne pathogens, improving indoor air quality and system efficiency. This installation provides a cleaner, healthier home environment.
