The sun produces three types of ultraviolet (UV) light: UVA, UVB and UVC. You are likely most familiar with UVA and UVB rays, which might result in sunburn unless you wear 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 provides exceptional germicidal benefits. In actuality, it has been used as a purification method for decades. As the highest energy portion of the UV radiation spectrum, UVC light helps kill microorganisms like bacteria, algae and fungi in just 10 seconds of contact. When placed in your HVAC system, germicidal UV lights could drastically enhance your indoor air quality.
How Do HVAC UV Lights Work?
Ultraviolet lamps are used within your ductwork, where they operate continuously. Air flows past the lights when the furnace or air conditioner operates, and powerful UVC rays inactivate and neutralize 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 forms of air cleaning possible, why should you think about placing a UV light in your HVAC system? Think about these pluses:
1. Sterilized Coils
The evaporator coil in your HVAC system is frequently damp, particularly when it’s hot. By constantly shining UVC light on the coil, mold and bacteria are unable to grow.
2. Healthier Indoor Air
Media air filters can latch onto tiny bacteria and viruses. UV lights lower the concentration of microorganisms in the air without reducing airflow.
3. Improved Efficiency
By sustaining normal airflow and keeping the equipment as clean as possible, UV lights help your HVAC system function more easily. This, in turn, lowers your energy costs each month.
4. Longer HVAC Life Span
Clean equipment operates more smoothly and needs repairs less regularly. It could even last years longer.
5. Reduced Condensate Drain Line Clogs
Air conditioners and high-efficiency furnaces generate condensate, which drains away through a nearby pipe. Over time, algae can clog the drain line. By halting organic growth in the first place, UVC lights minimize the chance of water damage from a clogged condensate drain pan.
Who Should Use Germicidal UV Lights?
When you review all the benefits they offer your HVAC system, UV lights could quickly prove useful in any house. You are most likely to recognize installing HVAC UV lights if you or anyone in your home has:
- Any respiratory issue
- Weakened immune system
If you’re thinking about installing germicidal UV lights, discuss it with Service Experts Heating & Air Conditioning. We can help you determine the ideal system based on your HVAC equipment and indoor air quality needs. It’s best to leave UV light installation and maintenance to an expert because UVC exposure can result in skin or eye injuries.
