Hello all of our friendly North Carolina residents who are reading our HVAC tips and tricks! We are here to share an idea that many families in the area have taken advantage of, and we want to share it with you as well. Ultraviolet light has been proven to kill airborne pathogens and remove unwanted viruses from your home, by placing these UV lights in your air ducts you are killing these germs as they are circulated through your home.

Is it worth it?

Please remember these lights are not a 100% cure for Coronavirus in your home, they ARE however a great safeguard for your family that anyone could justify.

 

UV lights are effective, but they work in a specific range. They’ll kill organic growths, such as mold or bacteria, but they have no effect on dust, pet dander or other allergens. In most residential cases, an HVAC company will install the UV light near the coils to prevent mold or bacteria growth as air passes through. Since all of the air passes through the coils, this also kills growths in the air. UV lights are particularly effective in humid climates, where evaporator coils can easily get wet.

Does UV Light work to combat COVID-19?

UV works! Ultraviolet lights were shown to kill mold, viruses and bacteria more than 100 years ago. In fact, in 1903, Niels Finsen was given the Noble Prize in Medicine for using UV to effectively treat patients with skin infections.

Today, UV lights are used for germicidal use in hospitals, restaurants and grocery stores. And they have been shown effective in killing sterilizing an HVAC system. Here are two examples:

1). In 2012, a study at Duke University Medical Center showed that UV lights killed 97% of bacteria that were resistant to antibiotics, the so-called superbug bacteria that are the toughest to kill.

2). The Journal of Applied and Environmental Biology reported in 2001 that germicidal UV radiation significantly reduces airborne fungi in air handling units.

UV Light Options for your HVAC System

Two types of UV lights are made for sanitizing your heating and air conditioning system. They have various names including purifying lights, germicidal lights, sanitizing lights and sterilization lights.

Coil Sanitizing Lights:

If you have central air conditioning, then you have an indoor coil. It is a prime location for the development of mold and bacteria. Why?

Because the coil is used to condense moisture from the air to dehumidify your home during AC cycles. As air passes over the coil, dirt, pet dander and other debris stick to its wet surface. The combination creates an ideal setting for the growth of mold and bacteria that can be spread through your home in the passing air.

Coil UV lights are the most common HVAC sterilizing lights. Single-lamp and dual-lamp models are produced. Coil sterilization lights are installed where they can shine directly onto the surface of the coil, and they are left on continuously.
