Will a UV Light Eliminate Mould in your Air Conditioning System?

Did you know that more than one in four Canadians have some form of diagnosed allergy? Many of these folks experience allergic reactions when exposed to moulds.

The thing is, mould is everywhere, including homes. Experts have identified over 270 mould species in Canadian homes.

Fortunately, ultraviolet (UV) germicidal lights for air conditioner coils can help reduce indoor mould. This guide will explain how a UV light for AC units work, so be sure to read on.

What Are Ultraviolet Germicidal Lights?

Ultraviolet germicidal lights are devices that use UVC radiation, a well-known disinfectant. These lamps can reduce the spread of pathogens, such as bacteria and viruses. For this reason, Canadian hospitals have been using them for almost a decade now.

UV germicidal lights work by emitting short-wavelength light, also known as “radiation.” In doing so, they can damage the genetic structures of microorganisms.

Aside from bacteria and viruses, UVC lights can also inactivate or kill the cells of moulds. UV lamps can also make moulds and other germs unable to reproduce.

According to studies, UV lights can reduce moulds and bacteria on surfaces by up to 99%.

How Does a UV Light for A/C Systems Work?

UV lights for ducted A/C duct systems can disinfect the air that flows through the ducts. As the air passes through the A/C, the light can kill the microorganisms it carries. This is one way UV lights work as effective air cleaners.

Moreover, HVAC technicians can also install UV light for A/C system coils and drain pans. In doing so, the lamp can help stop the growth of bacteria and mould on these often-damp surfaces. By retarding mould growth, UV lamps can render moulds unable to release more spores into the air.

Always keep in mind that moulds can grow and spread within 48 hours under humid and moist conditions. The thing is, A/C coils and drain pans are always damp when the AC is in operation due to condensation. From there, the moulds can spew out their spores and particles into the air.

So with a UV light for your HVAC system, you can stop moulds from spreading into your home.

As a bonus, UV lamps can also help keep your air conditioning system efficient. They can do so by preventing moulds from reproducing enough to cover A/C coils. Clean, well-maintained air conditioner coils perform better and are more energy-efficient.

Who Can Install UV Lights for Air Conditioners?

As beneficial as UV germicidal lamps are, mishandling them can result in safety risks. Their placement within the AC or the air ducts also influences their effectiveness. For this reason, it’s best to hire a licensed HVAC contractor to install UV lights in your A/C.

UV Lights for Healthier Indoor Air

As you can see, a UV light for A/C systems can help reduce moulds and germs in the air, the ducts, and the equipment itself. With these lamps in your HVAC system, you can be on your way to breathing healthier, safer indoor air.
