Do UV Lights in Your HVAC System Eradicate Viruses?

The sun produces three types of ultraviolet (UV) light: UVA, UVB and UVC. You are likely most familiar with UVA and UVB rays, which can cause sunburn unless you use a broad-spectrum sunscreen. UVC rays are separate. The sun still produces them, but the earth’s ozone layer absorbs all UVC rays, so you don’t experience them in nature.

UVC light provides exceptional 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 kill microorganisms such as bacteria, algae and fungi in under 10 seconds of contact. When used in your HVAC system, germicidal UV lights could seriously boost your indoor air quality.

How Do HVAC UV Lights Work?

Ultraviolet lamps are placed within your ductwork, where they work constantly. Air flows past the lights when the furnace or air conditioner heats or cools, and intense UVC rays inactivate and destroy the majority of viruses, bacteria or mold floating in the air. Inactivated microorganisms cannot reproduce and die shortly after UVC exposure.

5 Benefits of Having UV Lights in Your HVAC System

With other forms of air cleaning on the market, why should you think about installing a UV light in your HVAC system? Review these advantages:

1. Sterilized Coils

The evaporator coil in your HVAC system is routinely damp, especially in the summer. By constantly shining UVC light on the coil, mold and bacteria are unable to flourish.

2. Fresher Indoor Air

Media air filters can latch onto minuscule bacteria and viruses. UV lights lower the amount of microorganisms in the air without reducing airflow.

3. Enhanced Efficiency

By sustaining enough airflow and keeping the equipment cleaner, UV lights help your HVAC system operate more efficiently. This, in turn, decreases your energy costs each month.

4. Longer HVAC Life Expectancy

Clean equipment operates more steadily and needs repairs less frequently. It can even run years longer.

5. Reduced Condensate Drain Line Clogs

Air conditioners and high-efficiency furnaces generate condensate, which drains away into a nearby pipe. As time passes, algae can obstruct the drain line. By stopping organic growth at the beginning, UVC lights reduce the risk of water damage from a blocked condensate drain pan.

Who Should Have Germicidal UV Lights?

When you review all the perks they offer your HVAC system, UV lights could clearly prove valuable in any house. You are more apt to appreciate adding HVAC UV lights if you or anyone in your household has:

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

If you’re considering getting germicidal UV lights, chat with Service Experts Heating & Air Conditioning. 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 trained technician since UVC exposure may lead to skin or eye injuries.
