The sun releases 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 wear a broad-spectrum sunscreen. UVC rays are different. The sun still creates them, but the earth’s ozone layer absorbs all UVC rays, so you don’t come across them in nature.
UVC light comes with useful 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 just 10 seconds of contact. When placed in your HVAC system, germicidal UV lights can seriously enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are installed within your ductwork, where they operate continuously. Air moves past the lights when the furnace or air conditioner operates, and intense UVC rays inactivate and destroy most viruses, bacteria or mold found in the air. Inactivated microorganisms won’t reproduce and die soon after UVC exposure.
5 Advantages of Using UV Lights in Your HVAC System
With other types of air cleaning on the market, why should you think about putting a UV light in your HVAC system? Think about these perks:
1. Cleaner Coils
The evaporator coil in your HVAC system is frequently wet, namely when it’s hot. By constantly shining UVC light on the coil, mold and bacteria will struggle to grow.
2. Healthier Indoor Air
Media air filters can trap tiny bacteria and viruses. UV lights lower the concentration of microorganisms in the air without reducing airflow.
3. Better Efficiency
By providing enough airflow and keeping the equipment as clean as possible, UV lights help your HVAC system perform more easily. This, in turn, lowers your energy costs each month.
4. Extended HVAC Life Span
Clean equipment performs more steadily and malfunctions less frequently. It could even last years longer.
5. Lower Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces create condensate, which travels away into a nearby pipe. As time passes, algae can obstruct the drain line. By halting organic growth in the first place, UVC lights lower the risk of water damage from an overflowing condensate drain pan.
Who Should Install Germicidal UV Lights?
When you think about all the perks they provide your HVAC system, UV lights could quickly prove worthwhile in any home. You are more likely to benefit from installing HVAC UV lights if you or anyone in your home has:
- Allergies
- Asthma
- Any respiratory condition
- Weakened immune system
