How Having UV Lights in Your HVAC System Kills Viruses

The sun emits three kinds of ultraviolet (UV) light: UVA, UVB and UVC. You are usually most familiar with UVA and UVB rays, which may cause sunburn unless you use a broad-spectrum sunscreen. UVC rays are distinct. The sun still produces them, but the earth’s ozone layer absorbs all UVC rays, so you don’t come across them in nature. 

UVC light provides fantastic germicidal benefits. In reality, it has been used as a purification method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps destroy 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 installed in your ductwork, where they operate continuously. Air flows past the lights when the furnace or air conditioner heats or cools, and intense UVC rays inactivate and destroy the majority of viruses, bacteria or mold found in the air. Inactivated microorganisms cannot reproduce and die soon after UVC exposure. 

5 Advantages of Installing UV Lights in Your HVAC System 

With other kinds of air cleaning possible, why should you think over installing a UV light in your HVAC system? Think about these advantages: 

1. Clean Coils 

The evaporator coil in your HVAC system is routinely damp, particularly when it’s hot. By constantly shining UVC light on the coil, mold and bacteria will struggle to take hold. 

2. Fresher Indoor Air 

Media air filters can trap tiny bacteria and viruses. UV lights lower the amount of microorganisms in the air without restricting airflow. 

3. Better Efficiency 

By sustaining steady airflow and keeping the equipment cleaner, UV lights help your HVAC system perform more efficiently. This, in turn, reduces your energy costs each month. 

4. Greater HVAC Life Span 

Clean equipment functions more smoothly and needs repairs less often. It could even work years longer. 

5. Lower 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 block the drain line. By stopping organic growth at the beginning, UVC lights lower the risk of water damage from an overflowing condensate drain pan. 

Who Should Use Germicidal UV Lights? 

When you think about all the advantages they grant your HVAC system, UV lights could easily prove useful in any house. You are more likely to benefit from installing HVAC UV lights if you or anyone in your household has: 

  • Allergies 
  • Asthma 
  • Any respiratory ailment 
  • Weaker immune system
