The sun emits three types of ultraviolet (UV) light: UVA, UVB and UVC. You are usually most familiar with UVA and UVB rays, which can produce sunburn unless you wear a broad-spectrum sunscreen. UVC rays are distinct. The sun still emits them, but the earth’s ozone layer soaks up all UVC rays, so you don’t experience them in nature.
UVC light provides exceptional germicidal benefits. In reality, 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 installed in your HVAC system, germicidal UV lights could dramatically enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are used inside your ductwork, where they work around the clock. Air flows past the lights when the furnace or air conditioner heats or cools, and powerful UVC rays inactivate and kill most viruses, bacteria or mold present in the air. Inactivated microorganisms don’t reproduce and die soon after UVC exposure.
5 Pluses of Installing UV Lights in Your HVAC System
With other types of air cleaning in use, why should you think about placing a UV light in your HVAC system? Think about these benefits:
1. Sterilized Coils
The evaporator coil in your HVAC system is routinely moist, particularly during warmer months. By continuously shining UVC light on the coil, mold and bacteria will not take hold.
2. Cleaner Indoor Air
Media air filters can latch onto minuscule bacteria and viruses. UV lights reduce the concentration of microorganisms in the air without reducing airflow.
3. Improved Efficiency
By providing adequate airflow and keeping the equipment as clean as possible, UV lights help your HVAC system operate more efficiently. This, in turn, decreases your energy costs from month to month.
4. Extended HVAC Life Span
Clean equipment performs more evenly and malfunctions less often. It could even last years longer.
5. Lower Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces produce condensate, which travels away through a nearby pipe. Over time, algae can obstruct the drain line. By halting organic growth initially, UVC lights lower the likelihood of water damage from a clogged condensate drain pan.
Who Should Install Germicidal UV Lights?
When you explore all the perks they provide your HVAC system, UV lights could quickly prove useful in any house. You are most likely to notice installing HVAC UV lights if you or anyone in your family has:
- Any respiratory issue
- Weakened immune system
If you’re looking into adding germicidal UV lights, talk with Niagara Home Services by Enercare. We can suggest the best system based on your HVAC equipment and indoor air quality needs. It’s important to leave UV light installation and maintenance to a trained technician because UVC exposure can lead to skin or eye injuries.
