Do UV Lights in Your HVAC System Eliminate Viruses?

The sun produces three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are usually 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 provides outstanding germicidal benefits. In actuality, it has been used as a purification method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps destroy microorganisms such as bacteria, algae and fungi within 10 seconds of contact. When used in your HVAC system, germicidal UV lights may dramatically boost your indoor air quality.

How Do HVAC UV Lights Work?

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

5 Pluses of Using UV Lights in Your HVAC System

With other kinds of air cleaning available, why should you consider installing a UV light in your HVAC system? Think about these perks:

1. Sterilized Coils

The evaporator coil in your HVAC system is routinely damp, particularly in the summer. By constantly shining UVC light on the coil, mold and bacteria cannot flourish.

2. Healthier Indoor Air

Media air filters may be effective at grabbing dust, pollen, dander and other big contaminants, but only the highest-rated HEPA filters can latch onto tiny bacteria and viruses. UV lights lower the amount of microorganisms in the air without reducing airflow.

3. Enhanced Efficiency

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

4. Extended HVAC Lifetime

Clean equipment functions more evenly and breaks down less often. It could even work years longer.

5. Reduced Condensate Drain Line Clogs

Air conditioners and high-efficiency furnaces create condensate, which flows away through a nearby pipe. Over time, algae can block the drain line. By stopping organic growth in the first place, UVC lights lower the chance of water damage from an overflowing condensate drain pan.

Who Should Have Germicidal UV Lights?

When you think about all the advantages they grant your HVAC system, UV lights could clearly prove helpful in any home. You are most likely to benefit from installing HVAC UV lights if you or anyone in your home has:

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

If you’re considering adding germicidal UV lights, talk with Knochelmann Service Experts. We can suggest the best system based on your HVAC equipment and indoor air quality needs. It’s important to leave UV light installation and maintenance to an expert because UVC exposure might cause skin or eye injuries.
