Facts About HVAC UV Lights

Having an optimally functioning HVAC system in your home or office is essential for comfort and success. One option you may be asked to consider is if you would like to have HVAC UV lights installed inside your system.  

The reason some people choose to install UV lights is that they work to either prevent or reduce the circulation of microorganisms in the home or office’s ductwork. There are a number of potential benefits provided by HVAC UV lights, which make them an important consideration for the overall functioning and performance of your HVAC system.

Why you might want UV lights in your HVAC system

Viruses and bacteria can grow inside of your HVAC system, contaminating the air in your home or office. Air contamination can cause a number of health issues, such as bacterial infections, asthma, allergies, and hypersensitivity pneumonitis. 

However, there are certain UV lights that can be used to purify the air. Ultraviolet Germicidal Light, also known as UVGI, is able to eliminate some viruses and bacteria. With proper installation, as well as the right spectrum of UV light, an HVAC UV light can help to increase the quality of air in your home or office. 


Keep in mind that there must be certain conditions met during installation in order for the UV light to be effective. This means that a professional and experienced HVAC technician is needed to complete your installation. 

With an HVAC UV light system, you may also want to utilize a HEPA filter, which is used to trap large particulates that have the potential to shield microorganisms from the UV light. The microorganisms keep the UV light from working efficiently, by essentially protecting those harmful bacteria and not cleaning the air, thus a HEPA filter is a great choice for supporting the work of the UVGI light.

HVAC UV Light Systems

If you decide to have a UV light installed, you will have two types of HVAC UV light installations to choose from; air sterilization and coil sterilization. 

Air sterilization

Also known as an In-Duct UVC system, air sterilization causes the UV-C light to disinfect the air while it cycles through the return ducts. This enables efficiency through the maximization of the UV-C light by causing the reflective surface within the particular ductwork section to be enhanced. 

Coil sterilization

When coil sterilization is chosen, there are UV-C lamps installed that are able to discover problem areas and other sensitive components which can include cooling coils, filters, and condensation pans. This type of installation can enable microbial growth in difficult areas to be found. 

Installing an HVAC UV-C Light

A household’s HVAC system is important, however if filled with microorganisms that cause viruses and bacteria, it can be harmful. It’s essential to have an effective way to filter out the negative and unhealthy components so that your HVAC system works optimally and provides top-notch air quality to your home or office.

By hiring an expert HVAC technician, you can have a UV light installed in your HVAC system to rid your air of the molds, viruses, and bacteria that can cause you harm.
