The sun releases three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are likely most familiar with UVA and UVB rays, which might result in sunburn unless you use a broad-spectrum sunscreen. UVC rays are distinct. The sun still creates 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 reality, it has been used as a purification method for decades. As the highest energy portion of the UV radiation spectrum, UVC light helps kill microorganisms such as bacteria, algae and fungi in just 10 seconds of contact. When installed in your HVAC system, germicidal UV lights can drastically enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are used inside your ductwork, where they function continuously. Air blows past the lights when the furnace or air conditioner heats or cools, and strong UVC rays inactivate and destroy most viruses, bacteria or mold found in the air. Inactivated microorganisms cannot reproduce and die briefly after UVC exposure.
5 Pluses of Installing UV Lights in Your HVAC System
With other types of air cleaning available, why should you think about putting a UV light in your HVAC system? Review these advantages:
1. Clean Coils
The evaporator coil in your HVAC system is frequently wet, especially when it’s hot. By constantly shining UVC light on the coil, mold and bacteria cannot flourish.
2. Healthier Indoor Air
Media air filters may be effective at grabbing dust, pollen, dander and other larger contaminants, but only the highest-rated HEPA filters can catch the smaller bacteria and viruses. UV lights decrease the concentration of microorganisms in the air without restricting airflow.
3. Enhanced Efficiency
By maintaining enough airflow and keeping the equipment clean, UV lights help your HVAC system perform more efficiently. This, in turn, lowers your energy costs every month.
4. Extended HVAC Life Span
Clean equipment works more smoothly and needs repairs less frequently. It can even work years longer.
5. Less Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces produce condensate, which flows away into a nearby pipe. As the years go by, algae can obstruct the drain line. By halting organic growth in the first place, UVC lights minimize the chance of water damage from a clogged condensate drain pan.
Who Should Install Germicidal UV Lights?
When you explore all the benefits they provide your HVAC system, UV lights could clearly prove helpful in any residence. You are more apt to notice installing HVAC UV lights if you or anyone in your home has:
- Any respiratory condition
- Compromised immune system
If you’re considering getting germicidal UV lights, discuss it with Golden Seal Service Experts. We can help you determine the perfect system based on your HVAC equipment and indoor air quality needs. It’s wise to leave UV light installation and maintenance to a professional as UVC exposure may result in skin or eye injuries.
