How Installing UV Lights in Your HVAC System Wipes Out Viruses

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

UVC light provides useful germicidal benefits. In reality, it has been used as a purification method for decades. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms like bacteria, algae and fungi in under 10 seconds of contact. When installed in your HVAC system, germicidal UV lights can seriously boost your indoor air quality.

How Do HVAC UV Lights Work?

Ultraviolet lamps are installed within your ductwork, where they operate continuously. Air blows past the lights when the furnace or air conditioner operates, and strong UVC rays inactivate and destroy most viruses, bacteria or mold present in the air. Inactivated microorganisms can’t reproduce and die shortly after UVC exposure.

5 Benefits of Using UV Lights in Your HVAC System

With other kinds of air cleaning available, why should you think about placing a UV light in your HVAC system? Consider these benefits:

1. Cleaner Coils

The evaporator coil in your HVAC system is routinely moist, namely in the summer. By continuously shining UVC light on the coil, mold and bacteria cannot flourish.

2. Cleaner Indoor Air

Media air filters can catch the smaller bacteria and viruses. UV lights lower the concentration of microorganisms in the air without restricting airflow.

3. Better Efficiency

By providing enough airflow and keeping the equipment as clean as possible, UV lights help your HVAC system work more effectively. This, in turn, lowers your energy costs every month.

4. Extended HVAC Lifetime

Clean equipment performs more smoothly and malfunctions less often. It might even last years longer.

5. Reduced Condensate Drain Line Clogs

Air conditioners and high-efficiency furnaces generate condensate, which drains away through a nearby pipe. As the years go by, algae can block the drain line. By halting organic growth initially, UVC lights decrease the odds of water damage from a blocked condensate drain pan.

Who Should Use Germicidal UV Lights?

When you consider all the pluses they grant your HVAC system, UV lights could clearly prove valuable in any house. You are most likely to notice adding HVAC UV lights if you or anyone in your family has:

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

If you’re considering adding germicidal UV lights, discuss it with Climate Control Service Experts. We can help you determine the best system based on your HVAC equipment and indoor air quality needs. It’s wise to leave UV light installation and maintenance to a trained technician since UVC exposure can lead to skin or eye injuries.
