The sun releases three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are likely 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 takes care of all UVC rays, so you aren’t exposed to them in nature.
UVC light comes with useful 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 eradicate microorganisms including bacteria, algae and fungi in just 10 seconds of contact. When installed in your HVAC system, germicidal UV lights can drastically improve your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are used in your ductwork, where they function around the clock. Air moves past the lights when the furnace or air conditioner operates, and strong UVC rays inactivate and destroy the majority of viruses, bacteria or mold found in the air. Inactivated microorganisms won’t reproduce and die shortly after UVC exposure.
5 Pluses of Installing UV Lights in Your HVAC System
With other forms of air cleaning possible, why should you consider putting a UV light in your HVAC system? Consider these perks:
1. Clean Coils
The evaporator coil in your HVAC system is often moist, especially in the summer. By continuously shining UVC light on the coil, mold and bacteria cannot grow.
2. Healthier Indoor Air
Media air filters might be effective at collecting dust, pollen, dander and other big contaminants, but only the highest-rated HEPA filters can trap minuscule bacteria and viruses. UV lights lower the amount of microorganisms in the air without restricting airflow.
3. Enhanced Efficiency
By maintaining enough airflow and keeping the equipment as clean as possible, UV lights help your HVAC system work more easily. This, in turn, decreases your energy costs from month to month.
4. Greater HVAC Lifetime
Clean equipment works more smoothly and breaks down less regularly. It can even work years longer.
5. Less Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces produce condensate, which drains away from a nearby pipe. As the years go by, algae can obstruct the drain line. By halting organic growth in the first place, UVC lights reduce the likelihood of water damage from a clogged condensate drain pan.
Who Should Install Germicidal UV Lights?
When you explore all the perks they grant your HVAC system, UV lights could clearly prove valuable in any residence. You are most likely to notice having HVAC UV lights if you or anyone in your home has:
- Any respiratory ailment
- Compromised immune system
If you’re considering getting germicidal UV lights, speak with Bob Brown Service Experts. We can suggest the perfect 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 may lead to skin or eye injuries.
