What Are UV Lights for HVAC?
Most often you’ll see ultraviolet light used in places like salons, spas and hospitals to kill bacteria and protect against mold growth. Installing UV lights in home HVAC units has the same effect.
Do HVAC UV Lights Really Work?
UV lights have been proven to kill mold. The lights are usually installed near the coils of the system to keep mold from growing there, ultimately improving airflow and efficiency. They can also reduce allergies and eliminate some odors. To ensure UV lights are effective you’ll still need to do routine maintenance to your HVAC system. Change your air filters every three months, or more often if you have pets.
UVC lights, which are the shortest wavelength UV lights, have been proven to prevent the spread of infectious diseases. Installing them in your HVAC units can mitigate the spread of pathogens through the air.
Are UV Lights Effective Against COVID-19?
According to the FDA, UVC light may be effective in inactivating the SARS-CoV-2 virus, which causes COVID-19. However, more research is needed to determine what level and duration of UVC light exposure is needed to fully inactivate the virus.
Types of UV Lights
Not all UV light systems are meant to prevent the spread of disease. It’s important to know the difference between the two types that can be installed in residential HVAC units:
This is the most common type. Coil systems are installed inside of your return air duct and are meant to keep mold from building up on the evaporator coil. The purpose of coil sterilization is to keep your coils clean to improve air quality and increase efficiency. Coil-sterilizing lights run 24/7.
This option is also installed in the return air duct and is meant to disinfect moving air while your heating or cooling system is running. This system uses UVC light to prevent the spread of pathogens. It can also prevent mold from building up on the coil.
