The sun emits three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are usually most familiar with UVA and UVB rays, which may produce sunburn unless you apply a broad-spectrum sunscreen. UVC rays are different. The sun still emits them, but the earth’s ozone layer soaks up all UVC rays, so you don’t experience them in nature.
UVC light offers fantastic germicidal benefits. In fact, it has been used as a cleaning method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms such as bacteria, algae and fungi in under 10 seconds of contact. When installed in your HVAC system, germicidal UV lights may seriously enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are installed inside your ductwork, where they run continuously. Air flows past the lights when the furnace or air conditioner operates, and powerful UVC rays inactivate and neutralize the majority of viruses, bacteria or mold present in the air. Inactivated microorganisms don’t reproduce and die shortly after UVC exposure.
5 Advantages of Having UV Lights in Your HVAC System
With other methods of air cleaning available, why should you think over installing a UV light in your HVAC system? Consider these advantages:
1. Clean Coils
The evaporator coil in your HVAC system is frequently wet, especially in the summer. By constantly shining UVC light on the coil, mold and bacteria cannot grow.
2. Healthier Indoor Air
Media air filters might be effective at trapping dust, pollen, dander and other larger particles, but only the highest-rated HEPA filters can catch tiny bacteria and viruses. UV lights lower the amount of microorganisms in the air without reducing airflow.
3. Improved Efficiency
By maintaining adequate airflow and keeping the equipment cleaner, UV lights help your HVAC system function more effectively. This, in turn, reduces your energy costs each month.
4. Greater HVAC Life Span
Clean equipment functions more steadily and needs repairs less often. It may even work years longer.
5. Less Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces create condensate, which flows away from a nearby pipe. Over time, algae can clog the drain line. By stopping organic growth in the first place, UVC lights minimize the likelihood of water damage from a blocked condensate drain pan.
Who Should Use Germicidal UV Lights?
When you review all the benefits they grant your HVAC system, UV lights could clearly prove useful in any residence. You are more likely to appreciate having HVAC UV lights if you or anyone in your household has:
- Any respiratory ailment
- Weaker immune system
If you’re thinking about adding germicidal UV lights, talk with Bryant Heating & Cooling Service Experts. We can recommend the best system based on your HVAC equipment and indoor air quality needs. It’s best to leave UV light installation and maintenance to an expert since UVC exposure might cause skin or eye injuries.
