Is UV Light for My AC or Furnace Worth It?

September 08, 2020

You likely are aware that the sun’s ultraviolet light (UV) is to blame for your painful sunburn. But did you realize that another kind of ultraviolet light can be useful for keeping your house’s air clean?

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

There’s another variety of UV light, called UVC. While unprotected exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be used to purify air, water and some surfaces.

Custom Air Systems Inc uses this light in some of our products to boost air filtration in Port St. Lucie residences.

How Ultraviolet Light is Used

This precise wavelength is referred to as “germicidal” because it destroys the DNA of bacteria and viruses. When pathogens move through this light, they eventually cease to exist as they can’t multiply.

This makes UVC light a strong replacement to chemical disinfection. Germicidal light is used in lots of disinfection procedures, including medical laboratories and hospitals. It’s also used to sterilize drinking water and other liquids made in food processing.

It’s becoming more popular to freshen air in residences in Port St. Lucie. That’s since it can also eradicate frequent indoor contaminants such as mold, mildew and bacteria. This is an extra advantage for loved ones who deal with seasonal allergies or asthma.

Uses for Germicidal UV Light in Your House

We install a germicidal UV light in your HVAC system’s ductwork. As the light is installed inside the ductwork, it makes it compatible with many heating and cooling equipment. This also keeps its light safely contained while providing strong disinfection for your residence’s air.

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

This whole-house solution is superior to a portable air purifier, which can only clean the air in a single area. Portable air purifiers also can’t clean your ductwork or the inside of your HVAC unit. A clean HVAC system is often a more efficient one that could even operate for a longer life span. And, some portable air purifiers are notorious for creating ozone.

When considering adding a germicidal lamp to your house, it’s essential to select one that doesn’t create ozone. While ozone is fantastic at eliminating odors and chemicals, it might also irritate your lungs and create other respiratory symptoms.
