The use of UV light in HVAC systems is becoming increasingly popular as a way to improve indoor air quality and system performance. 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 a UV light system designed to disinfect air in the return air duct of the air conditioner is a great way to keep your home's air clean and healthy. UV light has germicidal properties, making it ideal for disinfecting air passing through the HVAC system.
The lights are placed on the supply vents, which are part of the ducts of the central air conditioning system. They are also good for limiting mold growth throughout the HVAC system and preventing certain respiratory diseases. 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 don't need germicidal UV lights in your HVAC system. However, if you do suffer from allergies or respiratory issues, installing a spiral UV lamp is recommended, as the coil is the main place for the growth of fungi and bacteria.
Filters need to be replaced more frequently than bulbs in a UV lighting system, making them difficult to maintain and reducing their effectiveness if you forget to change them. Installing the lamp as close to the center of the duct as possible will ensure that the UV light absorbs as much air as possible when the air conditioner or boiler is turned on. By placing UV lights on systems, air conditioning condenser coils or main ducts, you can kill microorganisms in a clean and efficient way to purify the air in your home. UV lighting devices, such as the 24 V RGF REME HVAC HALO air purification system lamp, attempt to counteract these contaminants.
Be sure to check and recheck the instructions that come with the UV lamp before you start drilling. Once every three months, turn off the air conditioning system, remove the lamp and clean the UV bulb with a soft cloth.
