Direct exposure to UVC lights can be hazardous to the skin and eyes, although, with the right type of germicidal lamps and proper installation, there is proven evidence of high germicidal UV light in HVAC effectiveness.
How Do UV Lights in HVAC Systems Work?
UVC lights are designed to emit particular wavelengths in the range of 254 nanometers (nm), which is effective at penetrating the DNA of microorganisms. The UV radiation is absorbed by the cells’ DNA which renders them unable to produce the needed proteins to survive or replicate. UV light does not immediately kill the germs, although it shortens their life span, and nullifies their ability to replicate and cause harm.
UVC light can penetrate the cells of viruses, bacteria, mold spores, fungi, and various germs when they pass through a heating, ventilation, and cooling (HVAC) system. Strategically installing germicidal UVC lamps in HVAC units helps to purify the air and disinfect HVAC equipment for longer, more efficient use. UV light in HVAC effectiveness is proven to improve indoor air quality for a healthier indoor environment.
UV Light in HVAC Effectiveness
There are several studies that evaluate UV light in HVAC effectiveness with promising results for UV light in HVAC systems in hospitals, offices, and schools. According to a study conducted by American Society of Heating, Refrigerating and Air-Conditioning Engineers, ASHRAE, and Penn State University, ultraviolet germicidal irradiation (UVGI) showed successful results for reducing the amount of fungi in air handling units and cited improvements in children with mold-induced asthma when installed in schools.
UV light has been used in hospitals and endorsed by the Centers for Disease Control and Prevention, CDC, for controlling the spread of tuberculosis in hospitals and healthcare facilities. UVC radiation is known to kill harmful microorganisms even antibiotic-resistant “superbugs” like MRSA, SARS and is even proven to be effective at killing the SARS-CoV-2 virus that causes the novel COVID-19.
How are UV Lights Installed in HVAC Systems?
Treating the volume of air in your home or office is immense, and only possible when installed properly in air handling units or HVAC systems since humans cannot be exposed to UVC light. Since the HVAC system draws air into the evaporator unit, forcing it out through air vents and registers throughout the home, UV light installed in the evaporator unit disinfects the air as it circulates.
Only a professional HVAC technician should install UV lights in HVAC systems for germicidal effectiveness. The lights must be installed in the right area with the right angle of exposure to disinfect the air as it passes through. The HVAC technician will clean the air handler system thoroughly prior to installing UV lights and should inspect all ductwork for leaks. With the right installation by a certified technician, UV lights in HVAC effectiveness will be at maximum levels to prevent airborne infection.
