Is UV Light for My AC or Furnace Worth It?

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) causes painful sunburn. But were you aware that a different type of ultraviolet light can be useful for keeping your home’s air clean?

The sun emits two types of dangerous UV rays, UVA and UVB. These harmful rays can lead to sunburn, skin cancer, wrinkles and other signs of premature aging.

There’s another concentration of UV light, known as UVC. While unprotected exposure to this ultraviolet light is bad for your skin or eyes, it can safely be used to purify air, water and various surfaces.

KDM Service Corporation uses this light in a few of our products to better air filtration in Tuscaloosa houses.

How Ultraviolet Light is Used

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

This makes UVC light a potent replacement to chemical disinfection. Germicidal light is employed in lots of disinfection applications, such as medical laboratories and hospitals. It’s also applied to clean drinking water and other liquids made in food processing.

It’s becoming more popular to freshen air in houses in Tuscaloosa. That’s because it can also eradicate typical indoor contaminants including mold, mildew and bacteria. This is an additional perk for loved ones who deal with seasonal allergies or asthma.

Having Germicidal UV Light in Your House

We install a germicidal UV light inside your HVAC system’s ductwork. As the light is placed in the ductwork, it makes it compatible with many heating and cooling equipment. This also keeps its light safely housed while providing great purification for your house’s air.

Dirty air is freshened in a two-step process, first flowing through your air filter and then the UV light before flowing across your residence. Even when your heat or air conditioning isn’t operating, these lights still operate to keep your air, ductwork and home comfort system clean.

This whole-house solution is better than a portable air purifier, which is limited to cleaning the air in one room. Portable air purifiers also can’t purify your ductwork or the interior of your HVAC unit. A clean HVAC system is typically a more efficient one that may even work for a longer life span. And, many portable air purifiers have a bad reputation for creating ozone.

When thinking about adding a germicidal lamp to your house, it’s critical to get one that doesn’t make ozone. While ozone is fantastic at eliminating odors and chemicals, it might also irritate your lungs and create other respiratory issues.
