Is Your HVAC UV Light Compatible with Your System?

Learn how to check if your HVAC system is compatible with UV light purifiers and how to install them for maximum effectiveness.

Is Your HVAC UV Light Compatible with Your System?

Are you considering installing ultraviolet (UV) lights inside your heating, ventilation and air conditioning (HVAC) system? UV light purifiers are an excellent addition to your air conditioning system because they offer many benefits of clean air in your home. With the right conditions and proper installation, UV lights can be very effective in killing viruses, mold, and bacteria. To determine if your HVAC UV light is compatible with your existing system, you should inspect the ducts around the light for small seams or openings. Additionally, if the bulb has been out for a while, you may notice biological growth on the inner coil, which is a sign that it needs to be replaced.

If you ask your HVAC technician how to check the UV bulb during the installation or maintenance appointment, they will provide instructions tailored to your application. Many UV lights for air conditioning systems come with a 110 V plug and some have a magnetic mounting bracket for easy installation. The process requires accessing the coil cabinet or duct network, installing a lamp that does not have a magnetic holder, and plugging it in. The Centers for Disease Control and Prevention (CDC) warns that the effectiveness of the lights depends on the intensity of the UV rays and the amount of time the contaminated surface is exposed to light.

If you don't replace a burned-out UV bulb, you won't be able to take advantage of its benefits. UV lights that are installed in air conditioning systems are ultraviolet germicidal irradiation lights, which are used to eliminate COVID-19 in tests that are being carried out. To check if the bulb is still working, simply look at the duct area where it is located. The specific lifespan of a UV bulb will depend on the type of system and manufacturer's recommendations.

Research indicates that 99.9% of viruses and bacteria found in air ducts can be destroyed using ultraviolet light technology to improve air quality. If you and your family members don't have respiratory problems or allergies, and if you don't have higher-than-normal rates of colds and other viruses, you probably won't need germicidal UV lamps in your air conditioning system.
