Do UV Lights in Your HVAC System Eliminate Viruses?

The sun releases three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are usually most familiar with UVA and UVB rays, which may result in sunburn unless you wear a broad-spectrum sunscreen. UVC rays are distinct. The sun still releases them, but the earth’s ozone layer takes care of all UVC rays, so you aren’t exposed to them in nature.

UVC light grants fantastic germicidal benefits. In reality, it has been used as a cleaning method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms including bacteria, algae and fungi in just 10 seconds of contact. When used in your HVAC system, germicidal UV lights may drastically improve your indoor air quality.

How Do HVAC UV Lights Work?

Ultraviolet lamps are installed in your ductwork, where they work around the clock. Air moves past the lights when the furnace or air conditioner operates, and powerful UVC rays inactivate and destroy nearly all viruses, bacteria or mold floating 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 consider installing a UV light in your HVAC system? Think about these pluses:

1. Sterilized Coils

The evaporator coil in your HVAC system is consistently damp, especially during warmer months. By always shining UVC light on the coil, mold and bacteria will not take hold.

2. Cleaner Indoor Air

Media air filters might be effective at collecting dust, pollen, dander and other large particles, but only the highest-rated HEPA filters can catch minuscule bacteria and viruses. UV lights reduce the amount of microorganisms in the air without restricting airflow.

3. Improved Efficiency

By providing normal airflow and keeping the equipment clean, UV lights help your HVAC system perform more efficiently. This, in turn, reduces your energy costs from month to month.

4. Longer HVAC Life Expectancy

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

5. Lower Chance of Condensate Drain Line Clogs

Air conditioners and high-efficiency furnaces generate condensate, which flows away through a nearby pipe. Over time, algae can clog the drain line. By preventing organic growth at the beginning, UVC lights lower the risk of water damage from a blocked condensate drain pan.

Who Should Use Germicidal UV Lights?

When you weigh all the pluses they offer your HVAC system, UV lights could clearly prove valuable in any residence. You are more likely to notice adding HVAC UV lights if you or anyone in your household has:

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

If you’re considering installing germicidal UV lights, speak with Service Experts Heating & Air Conditioning. We can suggest the perfect system based on your HVAC equipment and indoor air quality needs. It’s important to leave UV light installation and maintenance to a professional as UVC exposure could result in skin or eye injuries.
