Ultraviolet (UV) lighting is a powerful tool for preventing the build-up of microbes on air filters, cooling coils, drain trays, and duct surfaces. Studies have shown that UV lights can reduce the amount of mold and bacteria in a home by up to 97%, as well as reduce the amount of airborne flu virus by 90%. Installing an HVAC UV lamp can eliminate mold and mildew, kill viruses and bacteria, and reduce odors, all of which will improve indoor air quality. However, purifying your home air with UV lights isn't as straightforward as some manufacturers might make it seem.
To work its magic, UV light has to be correctly installed in the air conditioning system (and UV lights can damage your eyes if you're not careful). Between the two models of UV light for air conditioning, the “best option” depends on the system and the needs. When a UV light is configured to illuminate the condenser coil and drain pan, it can be highly effective in preventing mold and bacteria from accumulating in these parts of the system. As air circulates around the house, it carries germs and allergens with it, which eventually pass through ultraviolet light, which disinfects the air as it recirculates around the house. If you're considering installing an HVAC UV lamp, it's best to consult a heating and cooling technician first. It's true that the idea of eliminating germs from your home just by shining a light in the air ducts sounds too good to be true, but UV HVAC lights can really improve your home's air quality.
Your entire air conditioning system will operate smoothly all year round. UV lighting reduces the buildup of contaminants in your system ducts; therefore, heat exchange and air flow improve dramatically. You can add a super powerful UV light to your air conditioning system, but that's probably an exaggeration and it costs you thousands and thousands of dollars. Finally, some sales HVAC technicians opt for UV light treatment in their system because it can kill bacteria. In fact, Niels Ryberg Finsen received the Nobel Prize in Medicine in 1903 for his work on the use of UV radiation to cure skin infections. In conclusion, installing an HVAC UV lamp is an effective way to improve indoor air quality by eliminating mold and mildew, killing viruses and bacteria, and reducing odors.
However, it's important to consult a heating and cooling technician before installing a UV light in your air conditioning system. The right model of UV light for your system will depend on your needs and budget. With proper installation and maintenance, you can enjoy improved air quality in your home.
