Adding UV lights to your home's HVAC system is one of the simplest ways to improve your home's indoor air quality. Ultraviolet light (UV) is the spectrum of sunshine that sanitizes the air. When invisible organic matter passes by the light, its genetic makeup alters, making it impossible for it to reproduce.
The lights will kill bacteria, viruses and mold spores as the air blows through your ducts. It's a completely silent and hidden way to reduce the amount of airborne pathogens inside your home. Hospitals, commercial kitchens and pharmacies have used these lights to sanitize the air for a long time. Only recently has this technology been available for home use.
When used inside your HVAC system, UV lights are typically placed inside or near the furnace and pointed toward the evaporator or cooling coil, where they'll reduce the risk of mold and bacteria growing over the coil.
When your air conditioner runs, it condenses water from your home's air. If it doesn't completely drain and dry on the coils or in the drain pan beneath the blower, mold and bacteria can grow. They may eventually cover the evaporator coil, and you lose substantial cooling efficiency. A film that's just 0.002 inches thick can cut your cooling efficiency by 9 percent, so the UV lights not only keep you healthier, they reduce energy consumption.
The fall and winter are cold and flu season because the air dries out and creates the perfect environment for fast transmission of viruses and bacteria. While mold is less of a problem during the winter, if you have any in your home that started growing in the summer, the lights will help stop its proliferation.
If you don't have a central air conditioner, the lights can be placed inside the ducts in a convenient place. The only maintenance associated with the lights is to have your professional HVAC contractor check them at them periodically to see that they're running and gently remove any dust that collects on them. Depending upon the quality of the unit and the run time, the light usually last 2-3 years before they need to be replaced.
