The sun emits three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are often most familiar with UVA and UVB rays, which may result in sunburn unless you use 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 come across them in nature.
UVC light provides outstanding germicidal benefits. In reality, it has been used as a purification method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps eradicate microorganisms such as bacteria, algae and fungi in under 10 seconds of contact. When placed in your HVAC system, germicidal UV lights could drastically enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are installed inside your ductwork, where they function constantly. Air moves past the lights when the furnace or air conditioner heats or cools, and powerful UVC rays inactivate and kill nearly all viruses, bacteria or mold floating in the air. Inactivated microorganisms don’t reproduce and die soon after UVC exposure.
5 Pluses of Using UV Lights in Your HVAC System
With other forms of air cleaning on the market, why should you think over placing a UV light in your HVAC system? Review these advantages:
1. Cleaner Coils
The evaporator coil in your HVAC system is routinely moist, namely during warmer months. By continuously shining UVC light on the coil, mold and bacteria will not flourish.
2. Healthier Indoor Air
Media air filters might be effective at grabbing dust, pollen, dander and other big pollutants, but only the highest-rated HEPA filters can catch minuscule bacteria and viruses. UV lights decrease the number of microorganisms in the air without restricting airflow.
3. Better Efficiency
By sustaining adequate airflow and keeping the equipment as clean as possible, UV lights help your HVAC system work more efficiently. This, in turn, reduces your energy costs each month.
4. Extended HVAC Life Span
Clean equipment performs more evenly and malfunctions less frequently. It may even last years longer.
5. Lower Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces create condensate, which drains away through a nearby pipe. As the years go by, algae can obstruct the drain line. By halting organic growth initially, UVC lights decrease the likelihood of water damage from a clogged condensate drain pan.
Who Should Install Germicidal UV Lights?
When you explore all the benefits they grant your HVAC system, UV lights could quickly prove worthwhile in any house. You are more apt to notice adding HVAC UV lights if you or anyone in your home has:
- Any respiratory issue
- Compromised immune system
If you’re looking into adding germicidal UV lights, discuss it with Service Experts Heating & Air Conditioning. We can suggest the best system based on your HVAC equipment and indoor air quality needs. It’s wise to leave UV light installation and maintenance to a professional since UVC exposure can lead to skin or eye injuries.
