The sun produces three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are often most familiar with UVA and UVB rays, which can result in sunburn unless you wear a broad-spectrum sunscreen. UVC rays are different. The sun still emits them, but the earth’s ozone layer takes care of 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 a long time. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms like bacteria, algae and fungi in just 10 seconds of contact. When used in your HVAC system, germicidal UV lights could dramatically improve your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are placed within your ductwork, where they work constantly. Air flows past the lights when the furnace or air conditioner runs, and intense UVC rays inactivate and destroy the majority of viruses, bacteria or mold present in the air. Inactivated microorganisms can’t reproduce and die soon after UVC exposure.
5 Pluses of Having UV Lights in Your HVAC System
With other methods of air cleaning in use, why should you think about installing a UV light in your HVAC system? Consider these advantages:
1. Sterilized Coils
The evaporator coil in your HVAC system is consistently wet, particularly when it’s hot. By constantly shining UVC light on the coil, mold and bacteria are unable to grow.
2. Cleaner Indoor Air
Media air filters may be effective at trapping dust, pollen, dander and other large particles, but only the highest-rated HEPA filters can trap the smaller bacteria and viruses. UV lights lower the concentration of microorganisms in the air without restricting airflow.
3. Improved Efficiency
By providing enough airflow and keeping the equipment as clean as possible, UV lights help your HVAC system work more easily. This, in turn, decreases your energy costs every month.
4. Greater HVAC Life Expectancy
Clean equipment functions more evenly and breaks down less regularly. It could even work years longer.
5. Lower Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces create condensate, which flows away into a nearby pipe. As time passes, algae can fill up the drain line. By halting organic growth at the beginning, UVC lights lower the odds of water damage from a blocked condensate drain pan.
Who Should Use Germicidal UV Lights?
When you consider all the pluses they provide your HVAC system, UV lights could easily prove worthwhile in any home. You are more likely to appreciate installing HVAC UV lights if you or anyone in your home has:
- Any respiratory condition
- Weakened immune system
If you’re thinking about getting germicidal UV lights, discuss it with Abbey Air Service Experts. We can recommend the perfect system based on your HVAC equipment and indoor air quality needs. It’s important to leave UV light installation and maintenance to an expert as UVC exposure could result in skin or eye injuries.
