The purpose of germicidal UV lamps is to eliminate microorganisms, including bacteria, fungi, viruses, and others, that may thrive within your HVAC system.

Microorganisms tend to thrive in damp and dark environments, which makes areas like the condensate drain pan and cool evaporator coil in your HVAC system particularly susceptible to their growth.

Through the emission of UV-C light rays, the UV lamps effectively neutralize microorganisms, either by rendering them inactive or by killing them outright. This prevents them from multiplying and causing problems within your HVAC system.

There are two types of germicidal UV lamps to choose from: return duct germicidal air purifiers and coil mounted sterilizers. Both products serve the same purpose of eliminating microbial activity in your HVAC system, but they have different functions:

• Germicidal UV air purifiers: These units are positioned inside your return air duct to sterilize contaminants before they are circulated throughout your HVAC system. For optimal air filtration, we suggest pairing a UV air purifier with a media filter. (While UV lamps sterilize microorganisms, they do not remove them from the air in your home.)
• Coil mounted UV sterilizers: These units are placed near your evaporator coil in the supply duct, where they subject the cooling coil to UV light. This process prevents microbial growth and eliminates contaminants after they have passed through your HVAC system.

An HVAC UV light may be beneficial for your air conditioner if:

• Someone in your household has respiratory issues or allergies. Mold spores and other pathogens can exacerbate allergy and asthma symptoms. By incorporating proper filtration, the UV light will sterilize microorganisms, which can then be captured by your system's air filter.
• You live in a warm and humid climate. In places like Sarasota, air conditioners are used for most months each year, which means the system is frequently cold and damp. This makes it more susceptible to mold growth than cooler regions that don't require as much air conditioning.
• A mold specialist has identified mold growth inside your HVAC system. In this case, you will need to have the mold removed by a mold remediation specialist. Afterward, installing a germicidal UV light will help to prevent future mold growth in your HVAC system. We also recommend scheduling regular HVAC tune-ups to allow technicians to inspect your system for microbial growth and address any problems before they worsen.
