An ultraviolet (UV) lamp can be added to your existing HVAC system and is installed on the evaporator coil or in the ducts near the coil. It helps keep the system clean by eliminating bacteria, mold and mildew so they don't pass through the air and circulate throughout the house. Studies on UV lights in heating, ventilation and air conditioning systems have also yielded significant results. A study found that UV lights could reduce the amount of mold and bacteria in a test home by 97%.
Another study showed that air purifiers with ultraviolet light could reduce the amount of flu virus in the air by 90%. In fact, the Nobel Prize in Medicine was awarded to Niels Ryberg Finsen in 1903 for his work using ultraviolet light radiation to cure skin infections. UV lights for air conditioning systems complement your air filtration system and provide an additional layer of protection. Since you spend up to 90% of your time indoors, it's important to consider the impact that contaminants can have on your long-term health and how UV lights in your air conditioning system can help.
By installing UV lights on your HVAC system to disinfect vulnerable edges and grooves, you can help prevent contaminants from circulating throughout the house. You can place a spiral sterilization lamp inside your HVAC system, or you can install an air sterilization light in the ducts. If you're concerned about indoor air quality, upgrading to a UV lighting system will improve the energy efficiency of your air conditioning system while reducing your energy costs. The cost of an HVAC UV lighting system will depend on the size of your system and the type of UV light that choose.
If you're interested in installing UV lights in your home, let Jacobs heating and air conditioning experts guide you. For example, it is recommended to replace a Carrier UV coil lamp every 9000 hours of operation or every year. As air circulates around the house, it carries with it germs and allergens that, over time, pass through ultraviolet light, which disinfects the air as it recirculates around the house. A study conducted in a commercial office building showed that the use of ultraviolet light can significantly reduce fungal levels.
UV lights also protect walls, ceilings, floors and furniture by preventing unsightly stains caused by microorganisms. UV lights are not a new technology and have been used for nearly a century to treat problems such as tuberculosis in hospitals. In addition to air purifiers, another way to improve indoor air quality is to install UV lights on the air conditioning system.
