The sun releases three varieties 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 use a broad-spectrum sunscreen. UVC rays are different. The sun still releases them, but the earth’s ozone layer takes care of all UVC rays, so you aren’t exposed to them in nature.
UVC light offers outstanding 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 eradicate microorganisms such as bacteria, algae and fungi in under 10 seconds of contact. When used in your HVAC system, germicidal UV lights could seriously enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are used inside your ductwork, where they run constantly. Air moves past the lights when the furnace or air conditioner operates, 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 Pluses of Having UV Lights in Your HVAC System
With other types of air cleaning on the market, why should you think about placing a UV light in your HVAC system? Review these pluses:
1. Clean Coils
The evaporator coil in your HVAC system is routinely moist, particularly when it’s hot. By constantly shining UVC light on the coil, mold and bacteria will struggle to flourish.
2. Fresher Indoor Air
Media air filters can be effective at catching dust, pollen, dander and other bigger contaminants, but only the highest-rated HEPA filters can catch the smaller bacteria and viruses. UV lights lower the amount of microorganisms in the air without restricting airflow.
3. Enhanced Efficiency
By providing enough airflow and keeping the equipment clean, UV lights help your HVAC system operate more efficiently. This, in turn, reduces your energy costs every month.
4. Extended HVAC Life Span
Clean equipment operates more smoothly and needs repairs less regularly. It can even work years longer.
5. Reduced Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces produce condensate, which flows away through a nearby pipe. As time passes, algae can fill up the drain line. By preventing organic growth in the first place, UVC lights decrease the likelihood of water damage from a clogged condensate drain pan.
Who Should Install Germicidal UV Lights?
When you consider all the perks they provide your HVAC system, UV lights could quickly prove helpful in any residence. You are most likely to recognize adding HVAC UV lights if you or anyone in your family has:
- Any respiratory ailment
- Compromised immune system
