UV Lights

UV & Me

The Carrier Ultraviolet Germicidal Lights (UV Light) are installed in close proximity to your indoor evaporator coil and destroy microbial growth on the coil. They are installed either in your plenum or coil case, directly above your evaporator coil, or mounted in your air handler, directly above your evaporator coil. This is where fungus and microbes commonly grow inside of an air conditioning system.

The UV Light works to clean the coil and prevent the growth of fungus on and around the coil by destroying the DNA of the fungus to kill or deactivate it. It is actually quite surprising to see the difference between a system without UV lights compared to a system with UV lights installed. In days past, we were accustomed to seeing mold and fungus growth on a coil, and eliminating the growths was done by either manually cleaning these surfaces or treating them with chlorine treatments.

Typical prices for UV Germicidal Lamps installed range from $500 to $950. UV bulbs require periodic replacement for maximum performance. The system includes either one or two bulbs, each costing approximately $90.

UV lights are not for all systems, as the UV can adversely affect the plastic drain pans of some condenser coils. All new Carrier evaporator coil drain pans are UV resistant and are constructed with the possibility of a UV light installation taken into account.
