The sun emits three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are usually most familiar with UVA and UVB rays, which might cause sunburn unless you apply a broad-spectrum sunscreen. UVC rays are distinct. The sun still produces them, but the earth’s ozone layer absorbs all UVC rays, so you don’t experience them in nature.
UVC light provides exceptional germicidal benefits. In fact, it has been used as a purification method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps kill microorganisms such as bacteria, algae and fungi within 10 seconds of contact. When used in your HVAC system, germicidal UV lights may dramatically enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are used within your ductwork, where they function continuously. Air moves past the lights when the furnace or air conditioner heats or cools, and intense UVC rays inactivate and kill most 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 available, why should you think about putting a UV light in your HVAC system? Think about these advantages:
1. Sterilized Coils
The evaporator coil in your HVAC system is frequently wet, namely when it’s hot. By always shining UVC light on the coil, mold and bacteria will struggle to grow.
2. Healthier Indoor Air
Media air filters can catch the smaller bacteria and viruses. UV lights reduce the amount of microorganisms in the air without affecting airflow.
3. Enhanced Efficiency
By maintaining adequate airflow and keeping the equipment as clean as possible, UV lights help your HVAC system perform more easily. This, in turn, reduces your energy costs each month.
4. Greater HVAC Life Expectancy
Clean equipment operates more evenly and needs repairs 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. Over time, algae can clog the drain line. By halting organic growth in the first place, UVC lights lower the risk of water damage from a blocked condensate drain pan.
Who Should Install Germicidal UV Lights?
When you think about all the benefits they grant your HVAC system, UV lights could quickly prove useful in any residence. You are more apt to notice adding HVAC UV lights if you or anyone in your family has:
- Any respiratory issue
- Weakened immune system
If you’re looking into getting germicidal UV lights, speak with Boehmers/Cronin Emery Service Experts. We can recommend 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 professional since UVC exposure may cause skin or eye injuries.
