How Having UV Lights in Your HVAC System Kills Viruses

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

UVC light offers incredible germicidal benefits. In actuality, it has been used as a purification method for a long time. 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 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 inside your ductwork, where they operate constantly. Air moves past the lights when the furnace or air conditioner heats or cools, and strong UVC rays inactivate and destroy nearly all viruses, bacteria or mold floating in the air. Inactivated microorganisms won’t reproduce and die shortly after UVC exposure.

5 Benefits of Having UV Lights in Your HVAC System

With other types of air cleaning available, why should you think over placing a UV light in your HVAC system? Think about these advantages:

1. Clean Coils

The evaporator coil in your HVAC system is frequently damp, particularly when it’s hot. By always shining UVC light on the coil, mold and bacteria will struggle to flourish.

2. Fresher Indoor Air

Media air filters can catch minuscule bacteria and viruses. UV lights decrease the concentration of microorganisms in the air without affecting airflow.

3. Better Efficiency

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

4. Longer HVAC Lifetime

Clean equipment works more steadily and needs repairs less frequently. It might even run years longer.

5. Less 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 fill up the drain line. By halting organic growth at the beginning, UVC lights decrease the odds of water damage from an overflowing condensate drain pan.

Who Should Have Germicidal UV Lights?

When you explore all the benefits they provide your HVAC system, UV lights could clearly prove worthwhile in any residence. You are most likely to benefit from having HVAC UV lights if you or anyone in your family has:

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

If you’re thinking about installing germicidal UV lights, speak with Service Experts Heating & Air Conditioning. 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 trained technician because UVC exposure can cause skin or eye injuries.
