Ultraviolet (UV) light systems are becoming increasingly popular for improving indoor air quality. Installing a UV light system is a cost-effective solution for improving the air quality in your home, as it requires minimal maintenance and energy. The process of installing a UV light system involves accessing the coil cabinet or duct network, installing a lamp that does not have a magnetic holder, and plugging it in. There are two types of UV light installations for HVAC: coil sterilization and air sterilization.
With coil sterilization, UV-C lamps are installed to treat sensitive and problem prone components, such as cooling coils, condensing trays, and filters. Air sterilization is also called the UVC inlet system and, with this method, the UV-C light disinfects the air as it passes through the return ducts. Mounting UV lights to all ducts in the system will require more work and is not recommended. Installing the light as close to the center of the duct as possible will ensure that as much air as possible comes into contact with the UV light when the air conditioner or boiler is on.
UV bulbs should be replaced every 9 to 12 months to ensure they are operating at maximum capacity. The CDC warns that the lights are more or less effective depending on the intensity of the UV rays and the time the contaminated surface is exposed to light. UV lights can improve your home's air quality by eliminating bacteria, viruses, and other microorganisms that can cause respiratory problems, allergies, and other health problems. Remember to choose the UV light system that best fits your home's needs, and consider hiring a professional if you're not comfortable with installing it yourself.
With proper installation, maintenance, and safety precautions, UV lights can provide significant benefits to your home and health.
