The sun produces three types of ultraviolet (UV) light: UVA, UVB and UVC. You are probably most familiar with UVA and UVB rays, which can result in sunburn unless you use a broad-spectrum sunscreen. UVC rays are different. 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 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 including bacteria, algae and fungi in just 10 seconds of contact. When installed in your HVAC system, germicidal UV lights may dramatically enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are placed within your ductwork, where they work continuously. Air blows past the lights when the furnace or air conditioner heats or cools, and powerful UVC rays inactivate and kill most viruses, bacteria or mold floating in the air. Inactivated microorganisms won’t reproduce and die shortly after UVC exposure.
5 Advantages of Installing UV Lights in Your HVAC System
With other types of air cleaning available, why should you consider placing a UV light in your HVAC system? Consider these pluses:
1. Sterilized Coils
The evaporator coil in your HVAC system is frequently damp, namely when it’s hot. By continuously shining UVC light on the coil, mold and bacteria will not take hold.
2. Fresher Indoor Air
Media air filters can be effective at trapping dust, pollen, dander and other bigger particles, but only the highest-rated HEPA filters can trap minuscule bacteria and viruses. UV lights reduce the concentration of microorganisms in the air without restricting airflow.
3. Improved Efficiency
By maintaining adequate airflow and keeping the equipment clean, UV lights help your HVAC system function more effectively. This, in turn, decreases your energy costs each month.
4. Extended HVAC Life Expectancy
Clean equipment operates more evenly and breaks down less regularly. It might even work years longer.
5. Reduced Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces generate condensate, which drains away into a nearby pipe. As time passes, algae can clog the drain line. By halting organic growth initially, UVC lights lower the risk of water damage from a clogged condensate drain pan.
Who Should Use Germicidal UV Lights?
When you weigh all the perks they grant your HVAC system, UV lights could easily prove useful in any house. You are more likely to benefit from adding HVAC UV lights if you or anyone in your household has:
- Any respiratory condition
- Weaker immune system
If you’re considering installing germicidal UV lights, talk with Service Experts Heating & Air Conditioning. We can suggest the best system based on your HVAC equipment and indoor air quality needs. It’s best to leave UV light installation and maintenance to a professional as UVC exposure may lead to skin or eye injuries.
