How Having UV Lights in Your HVAC System Kills Viruses

The sun releases three types of ultraviolet (UV) light: UVA, UVB and UVC. You are probably most familiar with UVA and UVB rays, which may produce sunburn unless you use a broad-spectrum sunscreen. UVC rays are separate. The sun still creates them, but the earth’s ozone layer soaks up all UVC rays, so you aren’t exposed to them in nature. 

UVC light comes with highly beneficial germicidal benefits. In actuality, 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 kill microorganisms like bacteria, algae and fungi in under 10 seconds of contact. When installed in your HVAC system, germicidal UV lights may dramatically improve your indoor air quality

How Do HVAC UV Lights Work? 

Ultraviolet lamps are installed inside your ductwork, where they function continuously. Air moves past the lights when the furnace or air conditioner runs, and strong UVC rays inactivate and neutralize most viruses, bacteria or mold floating in the air. Inactivated microorganisms don’t reproduce and die soon after UVC exposure. 

5 Pluses of Installing UV Lights in Your HVAC System 

With other kinds of air cleaning on the market, why should you think over placing a UV light in your HVAC system? Consider these advantages: 

1. Cleaner Coils 

The evaporator coil in your HVAC system is routinely damp, particularly during warmer months. By continuously shining UVC light on the coil, mold and bacteria are unable to flourish. 

2. Cleaner Indoor Air 

Media air filters can catch the smaller bacteria and viruses. UV lights decrease the number of microorganisms in the air without reducing airflow. 

3. Better Efficiency 

By sustaining normal airflow and keeping the equipment cleaner, UV lights help your HVAC system operate more effectively. This, in turn, decreases your energy costs each month. 

4. Longer HVAC Lifetime 

Clean equipment functions more smoothly and needs repairs less often. It can even last years longer. 

5. Lower Chance of Condensate Drain Line Clogs 

Air conditioners and high-efficiency furnaces produce condensate, which drains away from a nearby pipe. As time passes, algae can obstruct the drain line. By stopping organic growth at the beginning, UVC lights minimize the chance of water damage from an overflowing condensate drain pan. 

Who Should Install Germicidal UV Lights? 

When you review all the pluses they provide your HVAC system, UV lights could easily prove valuable in any home. You are more likely to notice installing HVAC UV lights if you or anyone in your family has: 

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