How Using UV Lights in Your HVAC System Eliminates Viruses

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

UVC light grants incredible germicidal benefits. In actuality, it has been used as a sterilization method for many years. As the highest energy portion of the UV radiation spectrum, UVC light helps destroy microorganisms such as bacteria, algae and fungi in under 10 seconds of contact. When placed in your HVAC system, germicidal UV lights may dramatically enhance your indoor air quality. 

How Do HVAC UV Lights Work? 

Ultraviolet lamps are placed in your ductwork, where they work around the clock. Air blows past the lights when the furnace or air conditioner runs, and intense UVC rays inactivate and neutralize the majority of viruses, bacteria or mold floating in the air. Inactivated microorganisms don’t reproduce and die soon after UVC exposure. 

5 Benefits of Installing UV Lights in Your HVAC System 

With other forms of air cleaning in use, why should you think about putting a UV light in your HVAC system? Think about these advantages: 

1. Sterilized Coils 

The evaporator coil in your HVAC system is routinely wet, especially when it’s hot. By continuously shining UVC light on the coil, mold and bacteria cannot grow. 

2. Cleaner Indoor Air 

Media air filters can latch onto the smaller bacteria and viruses. UV lights decrease the amount of microorganisms in the air without affecting airflow. 

3. Better Efficiency 

By sustaining normal airflow and keeping the equipment as clean as possible, UV lights help your HVAC system run more easily. This, in turn, decreases your energy costs from month to month. 

4. Extended HVAC Lifetime 

Clean equipment works more steadily and breaks down less frequently. It can even last years longer. 

5. Less Chance of Condensate Drain Line Clogs 

Air conditioners and high-efficiency furnaces produce condensate, which flows away from a nearby pipe. Over time, algae can block the drain line. By preventing organic growth in the first place, UVC lights lower the odds of water damage from a blocked condensate drain pan. 

Who Should Install Germicidal UV Lights? 

When you think about all the pluses they provide your HVAC system, UV lights could easily prove helpful in any home. You are more apt to notice installing HVAC UV lights if you or anyone in your household has: 

• Allergies 

• Asthma 
• Any respiratory issue 
• Weakened immune system 

If you’re considering installing germicidal UV lights, chat with Bryant Heating & Cooling Service Experts. We can recommend the best system based on your HVAC equipment and indoor air quality needs. It’s important to leave UV light installation and maintenance to an expert because UVC exposure could lead to skin or eye injuries.
