UV Lights and Your Air Conditioning System

One of the important services that we provide for homes in Springfield and the surrounding areas is the installation of UV germicidal lights into the HVAC system. This is the most effective way to eliminate harmful biological pollutants from moving through the air of your home. The ultraviolet radiation from these lights destroys bacteria, mold spores, viruses, and various other unhealthy microorganisms. This is particularly helpful during the hot and humid weather that we experience here, which encourages the development of mold.

However, there is another important job that UV germicidal lights perform—and it has to do with your air conditioner.

The Moldy Air Conditioner Problem

If you ever notice a peculiar “moldy” smell coming from the vents of your home when the AC is running, or a smell like dirty socks, then your air conditioner has probably developed mold across its evaporator coil. Appropriately, this is often called “dirty sock syndrome.”

It’s no surprise that mold can start to develop here. Water condenses across the coil as it absorbs heat from the air. Most of the water drips off into a pan below, but in humid weather too much can accumulate and make it easy for mold to grow. Not only does this create an unpleasant smell and release spores into the air, but it also makes it harder for the AC to work efficiently.

How the UV Lights Figure Into This

When UV germicidal lights are integrated into an HVAC system, they are set so they shine directly onto the air conditioner’s evaporator coils. This kills off any mold, and prevents mold from developing in the future. So if you are encountering trouble with a moldy air conditioning and “dirty sock syndrome,” call up indoor air quality and HVAC specialists to have UV lights installed.
