Achieving maximum comfort isn't just about controlling temperature—it's also about controlling other factors that can undercut that comfort, including air pollution. UV germicidal lights are a common HVAC system add-on that offer a broad range of benefits for your HVAC equipment as well as your home. The following offers three good reasons to include UV lights as a part of your HVAC system.
They Prevent Mold Buildup Inside Your HVAC Unit
The dark and damp confines of your indoor HVAC unit are the ideal place for mold and mildew to flourish. Unchecked mold growth can cause a number of issues for your HVAC system. For instance, mold on the evaporator coil can block air from reaching the coil, resulting in reduced performance and ice buildup on the coil itself.
Installing a series of UV lights near the evaporator coil can help prevent mold and mildew from growing on the coil and other areas with direct exposure to UV light. The UV-C radiation emitted by these lights undoes the DNA bonds of mold and other microorganisms, making survival and reproduction nearly impossible.
They Improve Your Home's Indoor Air Quality
Recent research has shown that the average home's indoor air is significantly more polluted than the air outside. Indoor air pollution can come from a wide variety of sources, from building materials and ordinary household products to biological pollutants and irritants including mold, mildew, and pollen. These and other pollutants can contribute to "sick building syndrome" and other health issues.
By neutralizing a wide variety of biological pollutants, including mold and bacteria, UV lights can significantly improve your home's indoor air quality. UV lights are also able to reduce or even eliminate volatile organic compounds (VOCs) from indoor air through photocatalytic oxidation. When used in conjunction with air purifiers and higher-quality air filters, UV lights can help keep the air in your home cleaner and healthier.
They Can Help Combat the Flu Virus
It's not just mold spores and dust that passes through the average HVAC system. The bacteria responsible for the common cold and flu virus can also circulate through your HVAC unit, resulting in the spread of millions of flu particles throughout your home.
Fortunately, UV lights are capable of neutralizing cold and flu bacteria within your HVAC system before they have a chance to spread elsewhere. Keep in mind that UV lights are only a part of the flu prevention picture. It's also important to keep surfaces throughout your home disinfected and to maintain optimal relative humidity levels to prevent virus survival.
