How Installing UV Lights in Your HVAC System Wipes Out Viruses

The sun releases three types of ultraviolet (UV) light: UVA, UVB and UVC. You are probably most familiar with UVA and UVB rays, which might produce sunburn unless you wear 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 don’t come across them in nature.

UVC light comes with highly beneficial germicidal benefits. In fact, 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 including bacteria, algae and fungi within 10 seconds of contact. When placed in your HVAC system, germicidal UV lights could seriously enhance your indoor air quality.

How Do HVAC UV Lights Work?

Ultraviolet lamps are used inside your ductwork, where they run constantly. Air moves past the lights when the furnace or air conditioner operates, and strong UVC rays inactivate and kill most viruses, bacteria or mold found in the air. Inactivated microorganisms cannot reproduce and die shortly after UVC exposure.

5 Benefits of Using UV Lights in Your HVAC System

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

1. Sterilized Coils

The evaporator coil in your HVAC system is consistently damp, particularly 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 can trap the smaller bacteria and viruses. UV lights lower the concentration of microorganisms in the air without restricting airflow.

3. Improved Efficiency

By sustaining adequate airflow and keeping the equipment cleaner, UV lights help your HVAC system perform more effectively. This, in turn, reduces your energy costs every month.

4. Extended HVAC Lifetime

Clean equipment operates more smoothly and breaks down less frequently. It could even last years longer.

5. Less Chance of Condensate Drain Line Clogs

Air conditioners and high-efficiency furnaces generate condensate, which travels away through a nearby pipe. As time passes, algae can fill up the drain line. By halting organic growth in the first place, UVC lights reduce the likelihood of water damage from a blocked condensate drain pan.

Who Should Use Germicidal UV Lights?

When you consider all the benefits they provide your HVAC system, UV lights could clearly prove valuable in any home. You are more apt to appreciate adding HVAC UV lights if you or anyone in your family has:

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