Is UV Light for My AC or Furnace Worth It?

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) is to blame for your painful sunburn. But did you know that another variety of ultraviolet light can be installed to keep your residence’s air clean?

The sun gives off two types of harmful UV rays, UVA and UVB. These harmful rays can cause sunburn, skin cancer, wrinkles and other types of premature aging.

There’s another variety of UV light, called UVC. While full exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be used to purify air, water and some surfaces.

Colvin's Heating and Cooling uses this light in a few of our solutions to enhance air filtration in Excelsior Springs houses.

Applications for Ultraviolet Light

This distinct wavelength is referred to as “germicidal” as it destroys the DNA of bacteria and viruses. When pathogens move through this light, they eventually die as they can’t spread.

This makes UVC light a powerful substitute to chemical disinfection. Germicidal light is used in many disinfection procedures, such as medical laboratories and hospitals. It’s also employed to purify drinking water and other liquids created in food processing.

It’s becoming a popular choice to freshen air in houses in Excelsior Springs. That’s because it can also eliminate typical indoor contaminants including mold, mildew and bacteria. This is an added benefit for loved ones who deal with seasonal allergies or asthma.

Installing Germicidal UV Light in Your House

We put a germicidal UV light within your HVAC system’s ductwork. Because the light is set within the ductwork, it makes it compatible with most heating and cooling equipment. This also keeps its rays safely housed while delivering powerful disinfection for your home’s air.

Dirty air is freshened in a two-step process, first moving through your air filter and then the UV light in advance of circulating across your home. Even when your heat or air conditioning isn’t on, these lights still run to keep your air, ductwork and home comfort equipment clean.

This whole-house solution is superior to a portable air purifier, which is limited to cleaning the air in a single space. Portable air purifiers also can’t freshen your ductwork or the innerworkings of your HVAC unit. A clean HVAC system is usually a more efficient one that could even run for a longer life span. And, many portable air purifiers are notorious for making ozone.

When thinking about buying a germicidal lamp for your house, it’s important to choose one that doesn’t make ozone. While ozone is good at eradicating odors and chemicals, it can also irritate your lungs and create other respiratory symptoms.
