Ultraviolet (UV) light has been scientifically proven to be an effective way to reduce microbial growth in air conditioning systems. Niels Ryberg Finsen was even awarded the Nobel Prize in Medicine in 1903 for his work on using UV light radiation to treat skin infections. Installing UV lights is one of the best improvements you can make to your home's air conditioning system. They are cost-effective, efficient, and easy to maintain, making them a great choice for anyone with an HVAC system. UV lights are great for eliminating bacteria and mold, but they won't do anything to get rid of dandruff or dust.
If allergies are caused by these factors, you may want to consider other HVAC system upgrades, such as installing an air purifier. UV lights are also beneficial for limiting mold growth throughout the HVAC system and preventing certain respiratory diseases. Having a UV light unit installed in your air conditioning system can also help reduce the chances of clogged drain pipes, which is one of the most common HVAC problems. A more complex system with lights mounted in all ducts will be more effective at keeping the system clean, but it is also more expensive and difficult to install. Even if your air conditioning system has a high-quality air filter, adding a UV light will help eliminate microorganisms and bacteria that may be too small to be caught by the filter.
UV lights sterilize viruses and bacteria before they can return to your home, helping to reduce airborne germs that can infect healthy family members or people with weaker immune systems. The cost of installing UV lights in an HVAC system depends on the type of lights you choose and whether or not an HVAC professional installs them. It is important to note that UV air purifiers are only effective if microorganisms pass through the UV-C light inside the air conditioning system. If there are any damaged or leaking ducts in the system, they can create a vacuum that attracts new contaminants (such as dust and debris) from attics and narrow spaces that don't pass through UV light and, therefore, are not sterilized. In areas that are particularly prone to the growth of mold and bacteria, such as areas with high humidity, UV light units are a great option for your air conditioning system. Most homeowners in Atlanta combine germicidal UV lights with an air filter that has a high MERV (minimum efficiency values) rating.
If you only feel like you're sneezing but have no other symptoms, dust or dandruff could be the real cause of your problem, and unfortunately, UV lights can't fix those problems. HVAC UV lights are worth it if you or your family suffer from allergies or illnesses caused by germs or particles that no other tool can remedy. The most common type of HVAC light is an entrance light that is placed near the central air system fan. These lights disinfect air as it circulates through ducts and remove harmful bacteria, mold, and other airborne contaminants.
