Why Using UV Lights in Your HVAC System Can Kill Viruses and Make Your Residences Air Cleaner

The sun releases 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 wear a broad-spectrum sunscreen. UVC rays are different. The sun still releases them, but the earth’s ozone layer soaks up all UVC rays, so you don’t experience them in nature.

UVC light provides useful germicidal benefits. In fact, 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 such as bacteria, algae and fungi in under 10 seconds of contact. When placed 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 operate continuously. 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 don’t reproduce and die soon after UVC exposure.

5 Pluses of Having UV Lights in Your HVAC System

With other kinds of air cleaning on the market, why should you consider placing a UV light in your HVAC system? Review these advantages:

1. Cleaner Coils

The evaporator coil in your HVAC system is often wet, especially when it’s hot. By constantly shining UVC light on the coil, mold and bacteria are unable to take hold.

2. Fresher Indoor Air

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

3. Improved Efficiency

By maintaining normal airflow and keeping the equipment cleaner, UV lights help your HVAC system perform more easily. This, in turn, decreases your energy costs every month.

4. Extended HVAC Lifetime

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

5. Less Chance of Condensate Drain Line Clogs

Air conditioners and high-efficiency furnaces produce condensate, which travels away from a nearby pipe. As the years go by, algae can clog the drain line. By preventing organic growth in the first place, UVC lights decrease the risk of water damage from an overflowing condensate drain pan.

Who Should Install Germicidal UV Lights?

When you consider all the benefits they grant your HVAC system, UV lights could easily prove helpful in any residence. You are more likely to appreciate adding HVAC UV lights if you or anyone in your household has:

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

If you’re thinking about adding germicidal UV lights, discuss it with Strand Brothers Service Experts. We can recommend the ideal system based on your HVAC equipment and indoor air quality needs. It’s best to leave UV light installation and maintenance to a professional as UVC exposure might result in skin or eye injuries.
