The sun produces three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are usually most familiar with UVA and UVB rays, which might result in sunburn unless you use a broad-spectrum sunscreen. UVC rays are distinct. The sun still creates them, but the earth’s ozone layer soaks up all UVC rays, so you don’t come across them in nature.
UVC light offers useful germicidal benefits. In actuality, it has been used as a purification method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps destroy microorganisms like bacteria, algae and fungi within 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 installed in your ductwork, where they operate constantly. Air flows past the lights when the furnace or air conditioner operates, and strong UVC rays inactivate and kill most viruses, bacteria or mold found in the air. Inactivated microorganisms don’t reproduce and die briefly after UVC exposure.
5 Pluses of Using UV Lights in Your HVAC System
With other methods of air cleaning possible, why should you consider placing a UV light in your HVAC system? Think about these pluses:
1. Clean Coils
The evaporator coil in your HVAC system is frequently damp, namely during warmer months. By always shining UVC light on the coil, mold and bacteria are unable to flourish.
2. Cleaner Indoor Air
Media air filters might be effective at grabbing dust, pollen, dander and other larger contaminants, 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 affecting airflow.
3. Enhanced Efficiency
By sustaining steady airflow and keeping the equipment as clean as possible, UV lights help your HVAC system perform more easily. This, in turn, decreases your energy costs from month to month.
4. Extended HVAC Lifetime
Clean equipment works more steadily and needs repairs less frequently. It can even work years longer.
5. Reduced Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces create condensate, which flows away from a nearby pipe. As time passes, algae can block the drain line. By halting organic growth at the beginning, UVC lights decrease the likelihood of water damage from an overflowing condensate drain pan.
Who Should Use Germicidal UV Lights?
When you consider all the perks they grant your HVAC system, UV lights could clearly prove helpful in any residence. You are more likely to notice installing HVAC UV lights if you or anyone in your household has:
- Any respiratory condition
- Compromised immune system
If you’re thinking about installing germicidal UV lights, speak with Norrell Service Experts. We can help you determine the best system based on your HVAC equipment and indoor air quality needs. It’s best to leave UV light installation and maintenance to a professional because UVC exposure may cause skin or eye injuries.
