The sun emits 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 apply a broad-spectrum sunscreen. UVC rays are separate. 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 exceptional germicidal benefits. In fact, 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 within 10 seconds of contact. When placed in your HVAC system, germicidal UV lights could seriously improve your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are placed inside your ductwork, where they function continuously. Air blows past the lights when the furnace or air conditioner runs, and strong UVC rays inactivate and kill drastically viruses, bacteria or mold found in the air. Inactivated microorganisms can't reproduce and die briefly after UVC exposure.
5 Advantages of Having UV Lights in Your HVAC System
With other kinds of air cleaning on the market, why should you think about placing a UV light in your HVAC system? Think about these perks:
1. Clean Coils
The evaporator coil in your HVAC system is consistently wet, especially in the summer. By constantly shining UVC light on the coil, mold and bacteria cannot take hold.
2. Fresher Indoor Air
Media air filters can latch onto minuscule bacteria and viruses. UV lights lower the concentration of microorganisms in the air without restricting airflow.
3. Better Efficiency
By sustaining enough airflow and keeping the equipment clean, UV lights help your HVAC system run more efficiently. This, in turn, decreases your energy costs every month.
4. Longer HVAC Lifetime
Clean equipment functions more smoothly and malfunctions less often. It may even work years longer.
5. Lower Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces produce condensate, which travels away through a nearby pipe. As time passes, algae can obstruct the drain line. By preventing organic growth initially, UVC lights lower the risk of water damage from a blocked condensate drain pan.
Who Should Install Germicidal UV Lights?
When you explore all the perks they provide your HVAC system, UV lights could clearly prove useful in any home. You are more apt to appreciate adding HVAC UV lights if you or anyone in your family has:
- Allergies
- Asthma
- Any respiratory condition
- Compromised immune system
