How Having UV Lights in Your HVAC System Wipes Out Viruses

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

UVC light comes with outstanding germicidal benefits. In fact, it has been used as a sterilization method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps kill microorganisms including bacteria, algae and fungi within 10 seconds of contact. When used in your HVAC system, germicidal UV lights may seriously boost your indoor air quality

How Do HVAC UV Lights Work? 

Ultraviolet lamps are used in your ductwork, where they function continuously. Air blows past the lights when the furnace or air conditioner heats or cools, and intense UVC rays inactivate and kill the majority of viruses, bacteria or mold floating in the air. Inactivated microorganisms don’t reproduce and die shortly after UVC exposure. 

5 Benefits of Having UV Lights in Your HVAC System 

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

1. Clean Coils 

The evaporator coil in your HVAC system is frequently wet, especially in the summer. By constantly shining UVC light on the coil, mold and bacteria are unable to take hold. 

2. Fresher Indoor Air 

Media air filters can latch onto the smaller bacteria and viruses. UV lights reduce the amount of microorganisms in the air without reducing airflow. 

3. Better Efficiency 

By providing steady airflow and keeping the equipment as clean as possible, UV lights help your HVAC system run more easily. This, in turn, lowers your energy costs from month to month. 

4. Longer HVAC Lifetime 

Clean equipment operates more smoothly and breaks down less often. It might even last years longer. 

5. Reduced Condensate Drain Line Clogs 

Air conditioners and high-efficiency furnaces generate condensate, which travels away from a nearby pipe. As the years go by, algae can fill up the drain line. By preventing organic growth initially, UVC lights reduce the risk of water damage from an overflowing condensate drain pan. 

Who Should Have Germicidal UV Lights? 

When you weigh all the perks they offer your HVAC system, UV lights could quickly prove useful in any home. You are more likely to appreciate installing HVAC UV lights if you or anyone in your home has: 

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