The sun releases 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 separate. The sun still produces them, but the earth’s ozone layer absorbs all UVC rays, so you aren’t exposed to them in nature.
UVC light offers incredible germicidal benefits. In actuality, it has been used as a cleaning method for a long time. As the highest energy portion of the UV radiation spectrum, UVC light helps kill microorganisms like bacteria, algae and fungi within 10 seconds of contact. When installed in your HVAC system, germicidal UV lights could dramatically boost your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are placed in your ductwork, where they operate continuously. Air flows past the lights when the furnace or air conditioner heats or cools, and strong UVC rays inactivate and kill most viruses, bacteria or mold found in the air. Inactivated microorganisms won’t reproduce and die soon after UVC exposure.
5 Benefits of Installing UV Lights in Your HVAC System
With other methods of air cleaning on the market, why should you think over placing a UV light in your HVAC system? Think about these advantages:
1. Cleaner Coils
The evaporator coil in your HVAC system is routinely moist, namely in the summer. By continuously shining UVC light on the coil, mold and bacteria are unable to take hold.
2. Cleaner Indoor Air
Media air filters can be effective at trapping dust, pollen, dander and other large particles, but only the highest-rated HEPA filters can latch onto minuscule bacteria and viruses. UV lights lower the number of microorganisms in the air without reducing airflow.
3. Improved Efficiency
By maintaining normal airflow and keeping the equipment clean, UV lights help your HVAC system operate more effectively. This, in turn, lowers your energy costs each month.
4. Extended HVAC Lifetime
Clean equipment works more smoothly and breaks down less often. It can even last years longer.
5. Lower Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces create condensate, which drains away from a nearby pipe. As time passes, algae can fill up the drain line. By stopping organic growth initially, UVC lights lower the risk of water damage from an overflowing condensate drain pan.
Who Should Use Germicidal UV Lights?
When you think about all the advantages they offer your HVAC system, UV lights could easily prove valuable in any home. You are more apt to appreciate having HVAC UV lights if you or anyone in your home has:
- Any respiratory ailment
- Compromised immune system
If you’re thinking about getting germicidal UV lights, talk with D.A. Bennett Service Experts. We can suggest 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 professional since UVC exposure may lead to skin or eye injuries.
