How Using UV Lights in Your HVAC System Eradicates Viruses

The sun emits three types of ultraviolet (UV) light: UVA, UVB and UVC. You are often most familiar with UVA and UVB rays, which can result in sunburn unless you apply a broad-spectrum sunscreen. UVC rays are distinct. 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 offers useful germicidal benefits. In fact, it has been used as a purification method for decades. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms like bacteria, algae and fungi within 10 seconds of contact. When installed in your HVAC system, germicidal UV lights could drastically improve your indoor air quality. 

How Do HVAC UV Lights Work? 

Ultraviolet lamps are placed in your ductwork, where they operate continuously. Air blows past the lights when the furnace or air conditioner operates, and strong UVC rays inactivate and kill nearly all viruses, bacteria or mold present in the air. Inactivated microorganisms won’t reproduce and die shortly after UVC exposure. 

5 Pluses of Having UV Lights in Your HVAC System 

With other methods of air cleaning possible, why should you consider installing a UV light in your HVAC system? Think about these perks: 

1. Cleaner Coils 

The evaporator coil in your HVAC system is often wet, namely when it’s hot. By constantly shining UVC light on the coil, mold and bacteria will not take hold. 

2. Fresher Indoor Air 

Media air filters can trap minuscule bacteria and viruses. UV lights decrease the concentration of microorganisms in the air without reducing airflow. 

3. Enhanced Efficiency 

By maintaining steady airflow and keeping the equipment cleaner, UV lights help your HVAC system work more effectively. This, in turn, lowers your energy costs each month. 

4. Longer HVAC Life Span 

Clean equipment functions more smoothly and needs repairs less frequently. It could even run years longer. 

5. Less Chance of Condensate Drain Line Clogs 

Air conditioners and high-efficiency furnaces produce condensate, which drains away through a nearby pipe. Over time, algae can clog the drain line. By halting organic growth at the beginning, UVC lights decrease the risk of water damage from a clogged condensate drain pan. 

Who Should Install Germicidal UV Lights? 

When you think about all the pluses they offer your HVAC system, UV lights could easily prove useful in any house. You are more likely to recognize installing HVAC UV lights if you or anyone in your home has: 

• Allergies 

• Asthma 
• Any respiratory issue 
• Weakened immune system 

If you’re looking into getting germicidal UV lights, discuss it with Service Experts Heating & Air Conditioning. We can suggest the ideal system based on your HVAC equipment and indoor air quality needs. It’s wise to leave UV light installation and maintenance to an expert as UVC exposure can cause skin or eye injuries.
