The sun emits three varieties of ultraviolet (UV) light: UVA, UVB and UVC. You are often most familiar with UVA and UVB rays, which can result in sunburn unless you wear a broad-spectrum sunscreen. UVC rays are separate. The sun still creates them, but the earth’s ozone layer soaks up all UVC rays, so you don’t come across them in nature.
UVC light offers exceptional germicidal benefits. In fact, it has been used as a purification method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms such as bacteria, algae and fungi in just 10 seconds of contact. When used in your HVAC system, germicidal UV lights may drastically boost your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are installed in your ductwork, where they run continuously. Air flows past the lights when the furnace or air conditioner runs, and intense UVC rays inactivate and neutralize the majority of viruses, bacteria or mold floating in the air. Inactivated microorganisms won’t reproduce and die briefly after UVC exposure.
5 Advantages of Using UV Lights in Your HVAC System
With other types of air cleaning in use, why should you think over installing a UV light in your HVAC system? Review these perks:
1. Sterilized Coils
The evaporator coil in your HVAC system is frequently wet, particularly during warmer months. By constantly shining UVC light on the coil, mold and bacteria cannot flourish.
2. Cleaner Indoor Air
Media air filters can catch the smaller bacteria and viruses. UV lights decrease the number of microorganisms in the air without affecting airflow.
3. Enhanced Efficiency
By sustaining steady airflow and keeping the equipment clean, UV lights help your HVAC system run more efficiently. This, in turn, lowers your energy costs from month to month.
4. Greater HVAC Life Expectancy
Clean equipment performs more evenly and malfunctions less often. It can even work years longer.
5. Less Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces create condensate, which travels away through a nearby pipe. Over time, algae can collect in the drain line. By halting organic growth initially, UVC lights minimize the odds of water damage from an overflowing condensate drain pan.
Who Should Have Germicidal UV Lights?
When you weigh all the advantages they provide your HVAC system, UV lights could easily prove worthwhile in any home. You are most likely to notice installing HVAC UV lights if you or anyone in your household has:
- Any respiratory condition
- Weakened 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 trained technician because UVC exposure could result in skin or eye injuries.
