The sun emits three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are often most familiar with UVA and UVB rays, which might produce sunburn unless you wear a broad-spectrum sunscreen. UVC rays are separate. The sun still emits them, but the earth’s ozone layer soaks up all UVC rays, so you aren’t exposed to them in nature.
UVC light offers fantastic 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 including bacteria, algae and fungi in just 10 seconds of contact. When installed in your HVAC system, germicidal UV lights may drastically enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are used in your ductwork, where they function constantly. Air flows past the lights when the furnace or air conditioner runs, and powerful UVC rays inactivate and kill the majority of viruses, bacteria or mold floating in the air. Inactivated microorganisms won’t reproduce and die shortly after UVC exposure.
5 Benefits of Installing UV Lights in Your HVAC System
With other methods of air cleaning possible, why should you think about installing a UV light in your HVAC system? Think about these advantages:
1. Clean Coils
The evaporator coil in your HVAC system is frequently moist, especially during warmer months. By continuously shining UVC light on the coil, mold and bacteria are unable to flourish.
2. Healthier Indoor Air
Media air filters can trap tiny bacteria and viruses. UV lights decrease the number of microorganisms in the air without affecting airflow.
3. Improved Efficiency
By sustaining adequate airflow and keeping the equipment as clean as possible, UV lights help your HVAC system work more effectively. This, in turn, reduces your energy costs from month to month.
4. Greater HVAC Life Expectancy
Clean equipment works more smoothly and malfunctions less frequently. It can even last years longer.
5. Less Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces generate condensate, which drains away from a nearby pipe. As the years go by, algae can block the drain line. By halting organic growth initially, UVC lights minimize the likelihood of water damage from a clogged condensate drain pan.
Who Should Use Germicidal UV Lights?
When you think about all the benefits they provide your HVAC system, UV lights could easily prove worthwhile in any home. You are more apt to benefit from adding HVAC UV lights if you or anyone in your home has:
- Any respiratory issue
- Weakened immune system
