What Types of HVAC UV Lights are Effective?

There are two main types of HVAC UV lights that are used to improve indoor air quality.

One type is called an In-Duct UVC system. With these types of UV lights, the air is disinfected as it cycles through the return air ducts. Because of the reflective properties of the interior of ductwork, the UV lights are maximized. Coil sterilization UV lights are installed inside your unit at the cooling coils, condensation pan, or filters, which helps target areas that are prone to collecting contaminants, yet are difficult to reach. Both types are very effective.
