How Installing UV Lights in Your HVAC System Kills Viruses

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

UVC light provides outstanding germicidal benefits. In reality, it has been used as a sterilization method for decades. As the highest energy portion of the UV radiation spectrum, UVC light helps break down microorganisms such as bacteria, algae and fungi within 10 seconds of contact. When installed in your HVAC system, germicidal UV lights may dramatically boost your indoor air quality.

How Do HVAC UV Lights Work?

Ultraviolet lamps are used within your ductwork, where they work continuously. Air moves past the lights when the furnace or air conditioner operates, and powerful UVC rays inactivate and kill nearly all viruses, bacteria or mold floating in the air. Inactivated microorganisms cannot reproduce and die briefly after UVC exposure.

5 Advantages of Installing UV Lights in Your HVAC System

With other forms of air cleaning possible, why should you think over installing a UV light in your HVAC system? Review these benefits:

1. Clean Coils

The evaporator coil in your HVAC system is frequently wet, particularly during warmer months. By constantly shining UVC light on the coil, mold and bacteria are unable to take hold.

2. Cleaner Indoor Air

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

3. Improved Efficiency

By providing adequate airflow and keeping the equipment as clean as possible, UV lights help your HVAC system operate more effectively. This, in turn, decreases your energy costs from month to month.

4. Extended HVAC Life Expectancy

Clean equipment operates more evenly and needs repairs less often. It could even run years longer.

5. Reduced 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 preventing organic growth at the beginning, UVC lights decrease the risk of water damage from an overflowing condensate drain pan.

Who Should Install Germicidal UV Lights?

When you weigh all the pluses they grant your HVAC system, UV lights could clearly prove helpful in any house. You are more apt to recognize having HVAC UV lights if you or anyone in your home has:

    • Allergies
    • Asthma
    • Any respiratory issue
    • Weakened immune system

If you’re considering installing germicidal UV lights, discuss it with Service Experts Heating, Air Conditioning & Plumbing. We can help you determine the perfect 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 could cause skin or eye injuries.
