How Having UV Lights in Your HVAC System Kills Viruses

The sun releases three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are probably most familiar with UVA and UVB rays, which may result in sunburn unless you use a broad-spectrum sunscreen. UVC rays are separate. The sun still creates them, but the earth’s ozone layer absorbs all UVC rays, so you don’t come across them in nature.

UVC light offers incredible 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 destroy microorganisms including bacteria, algae and fungi within 10 seconds of contact. When installed in your HVAC system, germicidal UV lights may dramatically enhance your indoor air quality.

How Do HVAC UV Lights Work?

Ultraviolet lamps are used within your ductwork, where they work around the clock. Air flows past the lights when the furnace or air conditioner runs, and intense UVC rays inactivate and kill nearly all viruses, bacteria or mold found in the air. Inactivated microorganisms won’t reproduce and die briefly after UVC exposure.

5 Benefits of Using UV Lights in Your HVAC System

With other types of air cleaning in use, why should you consider installing a UV light in your HVAC system? Review these advantages:

1. Cleaner Coils

The evaporator coil in your HVAC system is frequently damp, namely during warmer months. By always shining UVC light on the coil, mold and bacteria are unable to grow.

2. Healthier Indoor Air

Media air filters can latch onto the smaller bacteria and viruses. UV lights reduce the amount of microorganisms in the air without affecting airflow.

3. Enhanced Efficiency

By maintaining adequate airflow and keeping the equipment cleaner, UV lights help your HVAC system work more easily. This, in turn, decreases your energy costs from month to month.

4. Greater HVAC Life Expectancy

Clean equipment works more evenly and breaks down less often. It can even last years longer.

5. Reduced Condensate Drain Line Clogs

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

Who Should Use Germicidal UV Lights?

When you weigh all the pluses they grant your HVAC system, UV lights could clearly prove useful in any residence. You are more apt to appreciate having HVAC UV lights if you or anyone in your household has:

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

If you’re looking into adding germicidal UV lights, speak with Service Experts Heating, Air Conditioning & Plumbing. We can suggest the perfect 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 could cause skin or eye injuries.
