How Installing UV Lights in Your HVAC System Kills Viruses

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

UVC light offers exceptional germicidal benefits. In fact, it has been used as a cleaning method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps kill microorganisms such as bacteria, algae and fungi in under 10 seconds of contact. When placed in your HVAC system, germicidal UV lights could seriously boost your indoor air quality

How Do HVAC UV Lights Work? 

Ultraviolet lamps are used within your ductwork, where they run around the clock. Air blows past the lights when the furnace or air conditioner runs, and intense UVC rays inactivate and destroy nearly all viruses, bacteria or mold found in the air. Inactivated microorganisms cannot reproduce and die briefly after UVC exposure. 

5 Benefits of Having UV Lights in Your HVAC System 

With other methods of air cleaning on the market, why should you think about installing a UV light in your HVAC system? Review these advantages: 

1. Clean Coils 

The evaporator coil in your HVAC system is consistently moist, particularly in the summer. By constantly shining UVC light on the coil, mold and bacteria will not grow. 

2. Fresher Indoor Air 

Media air filters can latch onto minuscule bacteria and viruses. UV lights decrease the number of microorganisms in the air without reducing airflow. 

3. Better Efficiency 

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

4. Longer HVAC Lifetime 

Clean equipment operates more evenly and malfunctions less often. It could even work years longer. 

5. Less Chance of Condensate Drain Line Clogs 

Air conditioners and high-efficiency furnaces create condensate, which drains away into a nearby pipe. As the years go by, algae can clog the drain line. By preventing organic growth at the beginning, UVC lights lower the chance of water damage from an overflowing condensate drain pan. 

Who Should Have Germicidal UV Lights? 

When you review all the advantages they provide your HVAC system, UV lights could quickly prove useful in any house. You are most likely to recognize adding HVAC UV lights if you or anyone in your household has: 

  • Allergies 
  • Asthma 
  • Any respiratory ailment 
  • Weaker immune system
