The sun releases three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are probably most familiar with UVA and UVB rays, which can result in 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 provides incredible germicidal benefits. In fact, it has been used as a purification method for decades. As the highest energy portion of the UV radiation spectrum, UVC light helps destroy microorganisms such as bacteria, algae and fungi in under 10 seconds of contact. When placed in your HVAC system, germicidal UV lights could seriously boost your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are installed in your ductwork, where they function constantly. Air blows past the lights when the furnace or air conditioner heats or cools, and strong UVC rays inactivate and kill the majority of viruses, bacteria or mold present in the air. Inactivated microorganisms don’t reproduce and die soon after UVC exposure.
5 Advantages of Using UV Lights in Your HVAC System
With other types of air cleaning possible, why should you think about installing a UV light in your HVAC system? Consider these benefits:
1. Cleaner Coils
The evaporator coil in your HVAC system is frequently moist, particularly during warmer months. By always shining UVC light on the coil, mold and bacteria will not take hold.
2. Cleaner Indoor Air
Media air filters can be effective at grabbing dust, pollen, dander and other big pollutants, but only the highest-rated HEPA filters can trap minuscule bacteria and viruses. UV lights decrease the number of microorganisms in the air without restricting airflow.
3. Better Efficiency
By maintaining steady airflow and keeping the equipment clean, UV lights help your HVAC system perform more easily. This, in turn, decreases your energy costs every month.
4. Extended HVAC Life Span
Clean equipment operates more evenly and malfunctions less frequently. It could even last years longer.
5. Lower Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces generate condensate, which flows away into a nearby pipe. Over time, algae can clog the drain line. By stopping organic growth at the beginning, UVC lights lower the chance of water damage from a clogged condensate drain pan.
Who Should Use Germicidal UV Lights?
When you weigh all the advantages they provide your HVAC system, UV lights could clearly prove worthwhile in any house. You are more likely to appreciate having HVAC UV lights if you or anyone in your home has:
- Any respiratory ailment
- Compromised immune system
