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 know that another kind of ultraviolet light can be used to keep your home’s air clean?

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

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

GV Heating & Air uses this light in some of our products to improve air filtration in Crystal and Twin Cities residences.

How Ultraviolet Light is Used

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

This makes UVC light a powerful substitute to chemical disinfection. Germicidal light is applied in many disinfection applications, like medical laboratories and hospitals. It’s also used to purify drinking water and other liquids made in food processing.

It’s growing in popularity to freshen air in homes in Crystal and Twin Cities. That’s because it can also eradicate frequent indoor contaminants including mold, mildew and bacteria. This is an additional advantage if someone in your household has seasonal allergies or asthma.

Having Germicidal UV Light in Your Home

We install a germicidal UV light in your HVAC system’s ductwork. Because the light is put within the ductwork, it makes it compatible with many heating and cooling units. This also keeps its rays securely restricted while providing strong disinfection for your house’s air.

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

This whole-house product is superior to a portable air purifier, which is restricted to cleaning the air in a single area. Portable air purifiers also can’t purify your ductwork or the interior of your HVAC equipment. A clean HVAC system is often a more efficient one that could even last longer. And, some portable air purifiers are notorious for producing ozone.

When thinking over getting a germicidal lamp for your residence, it’s critical to select one that doesn’t produce ozone. While ozone is fantastic at eradicating odors and chemicals, it can also irritate your lungs and create other respiratory problems.
