The sun releases three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are usually most familiar with UVA and UVB rays, which may produce sunburn unless you wear 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 come across them in nature.
UVC light provides highly beneficial germicidal benefits. In fact, it has been used as a purification method for decades. 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 used in your HVAC system, germicidal UV lights could dramatically enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are placed in your ductwork, where they work around the clock. Air moves past the lights when the furnace or air conditioner runs, and powerful UVC rays inactivate and neutralize the majority of viruses, bacteria or mold found in the air. Inactivated microorganisms don’t reproduce and die soon after UVC exposure.
5 Benefits of Having UV Lights in Your HVAC System
With other kinds of air cleaning possible, why should you think over putting a UV light in your HVAC system? Review these benefits:
1. Clean Coils
The evaporator coil in your HVAC system is frequently wet, particularly when it’s hot. By always shining UVC light on the coil, mold and bacteria will not flourish.
2. Fresher Indoor Air
Media air filters can latch onto tiny bacteria and viruses. UV lights decrease the amount of microorganisms in the air without restricting airflow.
3. Better Efficiency
By providing adequate airflow and keeping the equipment as clean as possible, UV lights help your HVAC system function more efficiently. This, in turn, lowers your energy costs from month to month.
4. Extended HVAC Life Span
Clean equipment works more smoothly and malfunctions less frequently. It could even last years longer.
5. Less Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces generate condensate, which travels away from a nearby pipe. As the years go by, algae can clog the drain line. By stopping organic growth at the beginning, UVC lights minimize the odds of water damage from an overflowing condensate drain pan.
Who Should Install Germicidal UV Lights?
When you explore all the pluses they provide your HVAC system, UV lights could easily prove valuable in any house. You are more likely to benefit from installing HVAC UV lights if you or anyone in your household has:
- Any respiratory condition
- Compromised immune system
If you’re considering installing germicidal UV lights, speak with Stallion Heating Plumbing Air Conditioning. We can recommend the ideal system based on your HVAC equipment and indoor air quality needs. It’s wise to leave UV light installation and maintenance to an expert as UVC exposure could result in skin or eye injuries.
