The sun emits three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are often most familiar with UVA and UVB rays, which may produce sunburn unless you use a broad-spectrum sunscreen. UVC rays are distinct. 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 offers 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 destroy microorganisms like bacteria, algae and fungi within 10 seconds of contact. When placed in your HVAC system, germicidal UV lights may dramatically improve your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are used in your ductwork, where they work constantly. Air moves past the lights when the furnace or air conditioner operates, and powerful UVC rays inactivate and kill the majority of viruses, bacteria or mold present in the air. Inactivated microorganisms can’t reproduce and die briefly after UVC exposure.
5 Pluses of Having UV Lights in Your HVAC System
With other kinds of air cleaning on the market, why should you consider placing a UV light in your HVAC system? Review these advantages:
1. Clean Coils
The evaporator coil in your HVAC system is consistently moist, especially when it’s hot. By continuously shining UVC light on the coil, mold and bacteria will not grow.
2. Fresher Indoor Air
Media air filters might be effective at trapping dust, pollen, dander and other big pollutants, but only the highest-rated HEPA filters can catch the smaller bacteria and viruses. UV lights reduce the amount of microorganisms in the air without reducing airflow.
3. Better Efficiency
By providing adequate airflow and keeping the equipment clean, UV lights help your HVAC system perform more efficiently. This, in turn, decreases your energy costs each month.
4. Longer HVAC Life Expectancy
Clean equipment functions more evenly and malfunctions less frequently. It can even last years longer.
5. Reduced Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces produce condensate, which drains away into a nearby pipe. As time passes, algae can collect in the drain line. By stopping organic growth initially, UVC lights minimize the likelihood of water damage from an overflowing condensate drain pan.
Who Should Use Germicidal UV Lights?
When you review all the perks they offer your HVAC system, UV lights could clearly prove helpful in any house. You are more likely to benefit from having HVAC UV lights if you or anyone in your home has:
- Any respiratory issue
- Weakened immune system
If you’re looking into adding germicidal UV lights, talk with Air Engineers 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 an expert since UVC exposure can lead to skin or eye injuries.
