For example, clean air can enter a building, but if a sick person is inside, UV systems for HVAC won't do much to prevent that person from spreading germs across surfaces and contact. A UV filtration system combines the power of UV lights to eliminate viruses and bacteria with a high MERV filter to trap other particles that can cause respiratory problems, such as pollen and dust. More recently, UV lights have gained popularity because they are said to be effective in eliminating the new coronavirus, COVID-19. The most common type of HVAC light is a duct light placed near the central air system fan. A final advantage of installing UV-C lamps in the air conditioning system is that they also destroy volatile organic compounds (VOCs), which cause unpleasant odors reminiscent of tobacco smoke. Once installed, UV lights require very little maintenance and only need attention when they need to be cleaned or replaced.
Once every three months, turn off the air conditioning system, remove the lamp and clean the UV bulb with a soft cloth. Spiral disinfectant lights are installed so that they work constantly and are placed in the areas most sensitive to microbial growth. In the long term, installing UV lighting in your HVAC system can save you money, as UV systems allow HVAC units to operate with up to 35% efficiency older. Most importantly, the UV lights that most HVAC technicians try to sell you aren't powerful enough to kill even a substantial amount of mold spores, bacteria, and viruses circulating through your system.
However, these lights are designed to work constantly, which means they will consume more energy than lights that disinfect the air. UV lights in HVAC systems work by eliminating bacteria, microorganisms, and mold to keep the air inside the house clean and safe. Be sure to check and recheck the instructions that come with the UV light before starting to pierce. A more complicated system with lights mounted on all ducts will be better for keeping the system clean, but installing them is more difficult and expensive.
This means that UV lights are also a great way to limit your future repair needs and, potentially, extend the life of your air conditioning system.
