How Using UV Lights in Your HVAC System Kills Viruses
The sun releases three types of ultraviolet (UV) light: UVA, UVB and UVC. You are probably most familiar with UVA and UVB rays, which may produce sunburn unless you use 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 exceptional germicidal benefits. In reality, it has been used as a cleaning 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 under 10 seconds of contact. When used in your HVAC system, germicidal UV lights can seriously enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are used in your ductwork, where they function constantly. Air moves past the lights when the furnace or air conditioner operates, and powerful UVC rays inactivate and kill most viruses, bacteria or mold present in the air. Inactivated microorganisms won’t reproduce and die soon after UVC exposure.
5 Benefits of Having UV Lights in Your HVAC System
With other forms of air cleaning in use, why should you consider placing a UV light in your HVAC system? Review these advantages:
1. Cleaner Coils
The evaporator coil in your HVAC system is consistently moist, namely in the summer. By always shining UVC light on the coil, mold and bacteria are unable to flourish.
2. Healthier Indoor Air
Media air filters can trap the smaller bacteria and viruses. UV lights reduce the amount of microorganisms in the air without reducing airflow.
3. Improved Efficiency
By maintaining adequate airflow and keeping the equipment clean, UV lights help your HVAC system perform more easily. This, in turn, decreases your energy costs from month to month.
4. Longer HVAC Life Expectancy
Clean equipment operates more evenly and malfunctions less frequently. It could even work years longer.
5. Lower Chance of Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces generate condensate, which drains away into a nearby pipe. As the years go by, algae can clog the drain line. By halting organic growth at the beginning, UVC lights decrease the likelihood of water damage from a clogged condensate drain pan.
Who Should Have Germicidal UV Lights?
When you explore all the pluses they offer your HVAC system, UV lights could clearly prove worthwhile in any house. You are more likely to notice adding HVAC UV lights if you or anyone in your home has:
- Any respiratory condition
- Compromised immune system
If you’re considering installing germicidal UV lights, discuss it with Service Experts Heating, Air Conditioning & Plumbing. We can recommend the ideal 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 since UVC exposure may result in skin or eye injuries.
