How Having UV Lights in Your HVAC System Wipes Out Viruses

The sun emits three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are likely 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 creates them, but the earth’s ozone layer takes care of all UVC rays, so you don’t experience them in nature.

UVC light provides highly beneficial germicidal benefits. In reality, 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 within 10 seconds of contact. When placed in your HVAC system, germicidal UV lights may drastically enhance your indoor air quality.

How Do HVAC UV Lights Work?

Ultraviolet lamps are placed inside your ductwork, where they function around the clock. Air moves past the lights when the furnace or air conditioner runs, and intense UVC rays inactivate and destroy nearly all viruses, bacteria or mold floating in the air. Inactivated microorganisms won’t reproduce and die shortly after UVC exposure.

5 Advantages of Having UV Lights in Your HVAC System

With other methods of air cleaning possible, why should you consider putting a UV light in your HVAC system? Think about these advantages:

1. Sterilized Coils

The evaporator coil in your HVAC system is often damp, especially in the summer. By constantly shining UVC light on the coil, mold and bacteria will not take hold.

2. Healthier Indoor Air

Media air filters can trap the smaller bacteria and viruses. UV lights reduce the concentration of microorganisms in the air without reducing airflow.

3. Enhanced Efficiency

By providing normal airflow and keeping the equipment clean, UV lights help your HVAC system operate more effectively. This, in turn, reduces your energy costs each month.

4. Extended HVAC Life Expectancy

Clean equipment operates more steadily and needs repairs less regularly. It might even last years longer.

5. Less Chance of Condensate Drain Line Clogs

Air conditioners and high-efficiency furnaces generate condensate, which drains away into a nearby pipe. As time passes, algae can collect in the drain line. By preventing organic growth initially, UVC lights decrease the odds of water damage from an overflowing condensate drain pan.

Who Should Use Germicidal UV Lights?

When you consider all the advantages they grant your HVAC system, UV lights could easily prove useful in any house. You are more apt to recognize installing HVAC UV lights if you or anyone in your home has:

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