The sun produces three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are likely most familiar with UVA and UVB rays, which might 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 offers highly beneficial germicidal benefits. In actuality, it has been used as a sterilization method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms like bacteria, algae and fungi in under 10 seconds of contact. When used in your HVAC system, germicidal UV lights could drastically improve your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are installed within your ductwork, where they work continuously. Air blows past the lights when the furnace or air conditioner operates, and intense UVC rays inactivate and kill nearly all viruses, bacteria or mold floating in the air. Inactivated microorganisms cannot reproduce and die soon after UVC exposure.
5 Advantages of Using UV Lights in Your HVAC System
With other types of air cleaning available, why should you consider installing a UV light in your HVAC system? Think about these benefits:
1. Cleaner Coils
The evaporator coil in your HVAC system is often wet, namely in the summer. By continuously shining UVC light on the coil, mold and bacteria will not flourish.
2. Healthier Indoor Air
Media air filters might be effective at catching dust, pollen, dander and other big pollutants, but only the highest-rated HEPA filters can latch onto the smaller bacteria and viruses. UV lights lower the concentration of microorganisms in the air without restricting airflow.
3. Better Efficiency
By providing adequate airflow and keeping the equipment cleaner, UV lights help your HVAC system perform more effectively. This, in turn, decreases your energy costs each month.
4. Longer HVAC Life Span
Clean equipment performs more steadily and breaks down less often. It can even work 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. As the years go by, algae can block the drain line. By halting organic growth in the first place, UVC lights reduce the odds of water damage from an overflowing condensate drain pan.
Who Should Have Germicidal UV Lights?
When you explore all the perks they provide your HVAC system, UV lights could easily prove helpful in any residence. You are more likely to notice having HVAC UV lights if you or anyone in your family has:
- Any respiratory condition
- Weaker immune system
If you’re looking into adding germicidal UV lights, talk with Service Experts Commercial HVAC. We can help you determine the ideal system based on your HVAC equipment and indoor air quality needs. It’s important to leave UV light installation and maintenance to an expert as UVC exposure might result in skin or eye injuries.
