Do UV Lights in Your HVAC System Kill Viruses?

The sun emits three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are probably most familiar with UVA and UVB rays, which might produce sunburn unless you use a broad-spectrum sunscreen. UVC rays are distinct. The sun still produces them, but the earth’s ozone layer takes care of all UVC rays, so you don’t come across them in nature.

UVC light provides incredible germicidal benefits. In reality, it has been used as a sterilization method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps destroy microorganisms like bacteria, algae and fungi in just 10 seconds of contact. When installed in your HVAC system, germicidal UV lights could dramatically enhance your indoor air quality.

How Do HVAC UV Lights Work?

Ultraviolet lamps are placed within your ductwork, where they function around the clock. Air moves past the lights when the furnace or air conditioner heats or cools, and strong UVC rays inactivate and destroy the majority of viruses, bacteria or mold present in the air. Inactivated microorganisms can’t reproduce and die briefly after UVC exposure.

5 Advantages of Using UV Lights in Your HVAC System

With other forms of air cleaning in use, why should you think about putting a UV light in your HVAC system? Consider these benefits:

1. Clean Coils

The evaporator coil in your HVAC system is often moist, especially in the summer. By always shining UVC light on the coil, mold and bacteria are unable to take hold.

2. Healthier Indoor Air

Media air filters can be effective at grabbing dust, pollen, dander and other large pollutants, but only the highest-rated HEPA filters can latch onto tiny bacteria and viruses. UV lights reduce the number of microorganisms in the air without restricting airflow.

3. Better Efficiency

By maintaining steady airflow and keeping the equipment clean, UV lights help your HVAC system function more efficiently. This, in turn, reduces your energy costs every month.

4. Extended HVAC Life Expectancy

Clean equipment works more evenly and malfunctions less frequently. It might even run years longer.

5. Lower Chance of Condensate Drain Line Clogs

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

Who Should Install Germicidal UV Lights?

When you think about all the perks they grant your HVAC system, UV lights could quickly prove helpful in any residence. You are more apt to benefit from installing HVAC UV lights if you or anyone in your family has:

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

If you’re looking into adding germicidal UV lights, chat with McKinley Heating Service Experts. We can recommend the ideal system based on your HVAC equipment and indoor air quality needs. It’s wise to leave UV light installation and maintenance to a professional because UVC exposure may lead to skin or eye injuries.
