Most germicidal UV-C HVAC purification units can be mounted on the return side of the supply of HVAC ducts, but depending on your needs and the system you choose, you can install the UV lights directly on the air controller, in the air return system, or in strategic areas along the ducts. For optimal performance, UV lights should be placed around reflective surfaces and in conjunction with high-efficiency filters. This is because they disinfect air as it circulates through ducts, eliminating harmful bacteria, mold, and other pollutants from the air. If you're looking to improve indoor air quality, installing an ultraviolet (UV) light in your air conditioning system is a great option.
The first step in installing a UV oven lamp is to determine the best location in your oven or air controller. Generally, it is recommended to install an A-shaped UV lamp above, in the center, and downstream of the coil. However, if mold has already grown in your heating, ventilation and air conditioning system and there is a specific corner or area of the air purifier prone to mold formation, then you should install the UV light so that it shines more brightly on the mold problem area. Once you've identified the ideal spot for your UV light, connect it to a nearby electrical outlet with an appropriately rated extension cord.
You can also carefully insert the UV bulb where it will be installed to get an idea that it will fit properly. Aside from that option, using a drill saw to cut holes is probably the most difficult aspect of installing a UV lamp. High-frequency UV light has enough energy to destroy the DNA of bacteria and other microorganisms, killing them and disinfecting the air. HVAC UV lights are also effective at limiting mold growth throughout the HVAC system and preventing certain respiratory diseases.
If you feel like the air purifier isn't getting enough UV light, you can always install an additional UV lamp in a different location or on the other side of the coil.
