The sun produces three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are likely most familiar with UVA and UVB rays, which can produce sunburn unless you apply a broad-spectrum sunscreen. UVC rays are different. The sun still produces them, but the earth’s ozone layer takes care of all UVC rays, so you aren’t exposed to them in nature.
UVC light comes with exceptional germicidal benefits. In actuality, it has been used as a sterilization method for a long time. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms including bacteria, algae and fungi in just 10 seconds of contact. When used in your HVAC system, germicidal UV lights may dramatically improve your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are placed inside your ductwork, where they work constantly. Air moves past the lights when the furnace or air conditioner operates, and powerful UVC rays inactivate and kill the majority of viruses, bacteria or mold present in the air. Inactivated microorganisms cannot reproduce and die shortly after UVC exposure.
5 Benefits of Using UV Lights in Your HVAC System
With other kinds of air cleaning on the market, why should you think about installing a UV light in your HVAC system? Review these pluses:
1. Cleaner Coils
The evaporator coil in your HVAC system is routinely damp, especially when it’s hot. By continuously shining UVC light on the coil, mold and bacteria are unable to flourish.
2. Healthier Indoor Air
Media air filters can be effective at catching dust, pollen, dander and other big contaminants, but only the highest-rated HEPA filters can trap the smaller bacteria and viruses. UV lights lower the number of microorganisms in the air without reducing airflow.
3. Enhanced Efficiency
By providing adequate airflow and keeping the equipment as clean as possible, UV lights help your HVAC system operate more easily. This, in turn, reduces your energy costs every month.
4. Longer HVAC Life Span
Clean equipment functions more evenly and needs repairs less frequently. It can even run years longer.
5. Less Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces create condensate, which flows away into a nearby pipe. Over time, algae can obstruct the drain line. By halting organic growth at the beginning, UVC lights minimize the chance of water damage from a blocked condensate drain pan.
Who Should Install Germicidal UV Lights?
When you consider all the perks they grant your HVAC system, UV lights could clearly prove valuable in any house. You are more apt to notice installing HVAC UV lights if you or anyone in your home has:
- Any respiratory condition
- Weaker immune system
If you’re considering getting germicidal UV lights, speak with Midland Air Service Experts. We can recommend the best system based on your HVAC equipment and indoor air quality needs. It’s best to leave UV light installation and maintenance to an expert because UVC exposure may cause skin or eye injuries.
