Do UV Lights in Your HVAC System Kill Viruses?

The sun emits three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are probably most familiar with UVA and UVB rays, which might result in sunburn unless you apply a broad-spectrum sunscreen. UVC rays are separate. The sun still produces them, but the earth’s ozone layer absorbs all UVC rays, so you aren’t exposed to them in nature.

UVC light grants outstanding germicidal benefits. In fact, 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 like bacteria, algae and fungi in just 10 seconds of contact. When installed in your HVAC system, germicidal UV lights could drastically improve your indoor air quality.

How Do HVAC UV Lights Work?

Ultraviolet lamps are placed inside your ductwork, where they operate constantly. Air moves past the lights when the furnace or air conditioner heats or cools, and intense UVC rays inactivate and destroy nearly all viruses, bacteria or mold found in the air. Inactivated microorganisms don’t reproduce and die soon after UVC exposure.

5 Advantages of Using UV Lights in Your HVAC System

With other forms of air cleaning in use, why should you think over putting a UV light in your HVAC system? Review these perks:

1. Clean Coils

The evaporator coil in your HVAC system is frequently moist, especially when it’s hot. By always shining UVC light on the coil, mold and bacteria are unable to flourish.

2. Cleaner Indoor Air

Media air filters might be effective at trapping dust, pollen, dander and other big contaminants, but only the highest-rated HEPA filters can latch onto minuscule bacteria and viruses. UV lights reduce the number of microorganisms in the air without restricting airflow.

3. Enhanced Efficiency

By sustaining normal airflow and keeping the equipment cleaner, UV lights help your HVAC system run more easily. This, in turn, reduces your energy costs from month to month.

4. Longer HVAC Life Expectancy

Clean equipment functions more evenly and malfunctions less regularly. It can even last years longer.

5. Lower Chance of Condensate Drain Line Clogs

Air conditioners and high-efficiency furnaces produce condensate, which travels away into a nearby pipe. As the years go by, algae can obstruct the drain line. By stopping organic growth initially, UVC lights reduce the odds of water damage from a blocked condensate drain pan.

Who Should Install Germicidal UV Lights?

When you think about all the advantages they provide your HVAC system, UV lights could quickly prove useful in any house. You are more apt to appreciate having HVAC UV lights if you or anyone in your household has:

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

If you’re thinking about getting germicidal UV lights, talk with Service Experts Heating & Air Conditioning. We can recommend the perfect system based on your HVAC equipment and indoor air quality needs. It’s best to leave UV light installation and maintenance to a trained technician as UVC exposure can cause skin or eye injuries.
