Ultraviolet (UV) lighting systems are one of the most cost-effective ways to improve the air quality in your home. These systems use a special type of UV light, known as UV-C, to destroy the nucleic acids that make up the DNA of harmful airborne bacteria and to disinfect the air as it passes through the system. A UV filtration system combines the virus-killing power of UV lights with a filter high in MerV to trap other particles that can cause respiratory distress, such as pollen and dust. For optimal effectiveness, UV lights should be directed to the condenser, coils, and other areas where moisture accumulates and light shines continuously. Installing a UV light system is more complex than just mounting it inside the air controller.
It requires drilling and careful positioning of the light to ensure that it is effective. If not installed correctly, it can damage your air conditioning system or not work properly. Additionally, filters must be changed more frequently than bulbs in a UV light system, making them difficult to maintain and reducing their effectiveness if you forget to change the filter. To get the most out of your UV light system, it should be installed as close to the center of the duct as possible. UV lights disinfect air as it circulates through the ducts and remove harmful bacteria, mold, and other contaminants from the air.
The cost of installing a UV light system varies depending on factors such as size, complexity, and location. Generally speaking, however, you can expect to pay anywhere from $200 to $1,000 for installation. It is important to note that while DIY installation may seem like a good way to save money, mistakes made during the process can make them ineffective, making any savings irrelevant.
