How Having UV Lights in Your HVAC System Eradicates Viruses

The sun emits three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are often most familiar with UVA and UVB rays, which might cause sunburn unless you wear a broad-spectrum sunscreen. UVC rays are different. The sun still emits them, but the earth’s ozone layer absorbs all UVC rays, so you don’t come across them in nature. 

UVC light comes with highly beneficial germicidal benefits. In reality, it has been used as a sterilization method for a long time. As the highest energy portion of the UV radiation spectrum, UVC light helps eradicate microorganisms including bacteria, algae and fungi within 10 seconds of contact. When placed in your HVAC system, germicidal UV lights may seriously enhance your indoor air quality

How Do HVAC UV Lights Work? 

Ultraviolet lamps are used within your ductwork, where they work continuously. Air moves past the lights when the furnace or air conditioner runs, and powerful UVC rays inactivate and destroy nearly all viruses, bacteria or mold floating in the air. Inactivated microorganisms can’t reproduce and die soon after UVC exposure. 

5 Pluses of Using UV Lights in Your HVAC System 

With other types of air cleaning in use, why should you consider putting a UV light in your HVAC system? Review these advantages: 

1. Sterilized Coils 

The evaporator coil in your HVAC system is routinely wet, especially during warmer months. By continuously shining UVC light on the coil, mold and bacteria will struggle to grow. 

2. Fresher Indoor Air 

Media air filters can catch the smaller bacteria and viruses. UV lights reduce the amount of microorganisms in the air without affecting airflow. 

3. Enhanced Efficiency 

By maintaining adequate airflow and keeping the equipment cleaner, UV lights help your HVAC system function more easily. This, in turn, lowers your energy costs each month. 

4. Extended HVAC Life Expectancy 

Clean equipment performs more steadily and malfunctions less often. It might even work years longer. 

5. Reduced Condensate Drain Line Clogs 

Air conditioners and high-efficiency furnaces create condensate, which travels away through a nearby pipe. As the years go by, algae can clog the drain line. By stopping organic growth in the first place, UVC lights reduce the odds of water damage from an overflowing condensate drain pan. 

Who Should Install Germicidal UV Lights? 

When you review all the pluses they offer your HVAC system, UV lights could quickly prove worthwhile in any house. You are more likely to benefit from adding HVAC UV lights if you or anyone in your family has: 

  • Allergies 
  • Asthma 
  • Any respiratory issue 
  • Weakened immune system
