The sun emits three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are probably most familiar with UVA and UVB rays, which may result in sunburn unless you use a broad-spectrum sunscreen. UVC rays are separate. The sun still creates them, but the earth’s ozone layer absorbs all UVC rays, so you don’t experience them in nature.
UVC light provides incredible germicidal benefits. In fact, it has been used as a cleaning method for decades. As the highest energy portion of the UV radiation spectrum, UVC light helps eradicate microorganisms such as bacteria, algae and fungi in just 10 seconds of contact. When installed in your HVAC system, germicidal UV lights could seriously boost your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are placed in your ductwork, where they work constantly. Air blows past the lights when the furnace or air conditioner runs, and strong UVC rays inactivate and neutralize most viruses, bacteria or mold present in the air. Inactivated microorganisms don’t reproduce and die soon after UVC exposure.
5 Benefits of Using UV Lights in Your HVAC System
With other forms of air cleaning in use, why should you think over placing a UV light in your HVAC system? Review these advantages:
1. Cleaner Coils
The evaporator coil in your HVAC system is often damp, especially during warmer months. By constantly shining UVC light on the coil, mold and bacteria will not flourish.
2. Healthier Indoor Air
Media air filters might be effective at grabbing dust, pollen, dander and other bigger particles, but only the highest-rated HEPA filters can trap tiny bacteria and viruses. UV lights reduce the concentration of microorganisms in the air without restricting airflow.
3. Improved Efficiency
By maintaining normal airflow and keeping the equipment as clean as possible, UV lights help your HVAC system run more effectively. This, in turn, lowers your energy costs every month.
4. Longer HVAC Life Expectancy
Clean equipment works more steadily and breaks down less often. It may even last years longer.
5. Reduced Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces generate condensate, which flows away through a nearby pipe. Over time, algae can clog the drain line. By halting organic growth at the beginning, UVC lights lower the risk of water damage from an overflowing condensate drain pan.
Who Should Have Germicidal UV Lights?
When you think about all the benefits they provide your HVAC system, UV lights could quickly prove useful in any house. You are most likely to appreciate adding HVAC UV lights if you or anyone in your household has:
- Any respiratory ailment
- Compromised immune system
