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 realize that another variety of ultraviolet light can be used to keep your house’s air clean?

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

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

PWA Heating & Cooling Inc uses this light in several of our solutions to better air filtration in Plainfield residences.

What is an Ultraviolet Light Used For?

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

This makes UVC light a potent alternative to chemical disinfection. Germicidal light is employed in lots of disinfection applications, including medical laboratories and hospitals. It’s also applied to sterilize drinking water and other liquids created in food processing.

It’s growing in popularity to disinfect air in homes in Plainfield. That’s since it can also eliminate frequent indoor contaminants like mold, mildew and bacteria. This is an added perk for loved ones who deal with seasonal allergies or asthma.

How to Use Germicidal UV Light in Your House

We place a germicidal UV light inside your HVAC system’s ductwork. Since the light is placed in the ductwork, it makes it compatible with most heating and cooling systems. This also keeps its rays carefully confined while delivering great purification for your home’s air.

Filthy air is freshened in a two-step process, first moving through your air filter and then the UV light prior to circulating throughout your residence. Even when your heat or air conditioning isn’t operating, these lights still run to keep your air, ductwork and home comfort unit clean.

This whole-house option is better than a portable air purifier, which is limited to cleaning the air in a single room. Portable air purifiers also can’t purify your ductwork or the innerworkings of your HVAC unit. A clean HVAC system is often a more efficient one that can even run longer. And, some portable air purifiers are notorious for making ozone.

When considering getting a germicidal lamp for your residence, it’s important to get one that doesn’t make ozone. While ozone is good at eliminating odors and chemicals, it could also irritate your lungs and create other respiratory issues.
