What are the Benefits of UV Lights in HVAC Systems

Do ultraviolet lights get the green light?

You may have heard of using ultraviolet (UV) light in your HVAC system, but is it even effective? The short answer is yes. The primary purpose of UV lights is to prevent mold and mildew from thriving in your vents. In this article, we’ll take a look at how UV lights work, as well as the advantages of installing UV lights into your HVAC system.

How do HVACs use UV light?

There are two ways that UV lights work when installed in HVACs. The first is called coil sterilization. This is when two rods (think lightsabers) are installed inside the air duct to sterilize the coil. Over time, coils inside the HVAC will accumulate dust and dirt. As a result, this will prevent the air conditioner from cooling properly. When this happens, you’ll usually notice a musty smell. By installing a UV light inside the air conditioning unit, you can combat the buildup around the coils.

The second way that UV lights work is called air sterilization. As the name suggests, UV sterilizes the air as it flows through the vents. This eliminates bacteria, pathogens, and other harmful organisms in the air.

What are the benefits of UV lights in HVACs?

Thinking of telling your HVAC technician to upgrade your HVAC system with UV lights? Here are some reasons to do so:

#1 Prevent Mold and Mildew

Mold is one of the most common issues that homeowners have to deal with. Since mold and mildew thrive in moist environments, it makes sense that your HVAC unit would become their breeding ground. UV light works by eliminating the mold inside your air conditioning unit. This is because UV light is germicidal, meaning it can get rid of germs at a short wavelength.

#2 Improved Indoor Air Quality

Does someone in your household have allergies? UV lights improve indoor air quality by getting rid of airborne fungi. In fact, studies have shown that UV lights can combat MRSA bacteria at a narrow wavelength.

#3 Improved Indoor Air Flow

Your home should never be excessively humid, or else it can turn into a breeding ground for bacteria. By using UV lights, you can enhance the flow of air inside your home. Plus, UV lights reduce odors inside your home so you can finally breathe comfortably.

#4 Prevents Disease

You don’t have to freak out when it’s flu season. Usually, when someone is sick, their viruses circulate in the air, causing others to catch their illness. With UV light, you can rest assured that it will effectively eliminate the microorganisms that would otherwise infect other members of your family.
