How UV Lights Improve Indoor Air Quality in Your HVAC System

Indoor air quality—or IAQ—plays a huge role in our comfort and health. If it’s poor, you could experience allergies, respiratory issues, and general discomfort. That’s why it’s important for homeowners and property owners to prioritize it for the sake of the occupants. An HVAC system has many components that contribute to said air quality, but UV lights are one of the major ones. Ultraviolet light can help with everything from eliminating mildew to destroying viruses, so let’s take a look at all the benefits they offer!

What Are UV Lights for HVAC Systems?

The particular type of UV light used in HVAC systems is UV-C light, which has an impressive ability to eliminate airborne contaminants. How does it do this? It destroys the DNA of things like mold, viruses, and bacteria, rendering them unable to reproduce and spread.

In heating and cooling systems, these lights are installed in one of two ways, which we’ll discuss here:

• Coil Sterilization: The light is placed close to the evaporator coil, which helps to prevent the coil’s surface from accumulating mold and bacteria.
• Air Sterilization: The light is installed inside the ductwork, eliminating airborne pathogens as they pass—which means they don’t get the chance to circulate throughout the building!

How UV Lights for HVAC Improve Air Quality

There are a variety of ways UV lights contribute to better air quality within your home or business…

Eliminating Mold and Mildew

Mold and mildew love moist, dark environments—such as ductwork. They’re able to thrive in these places, which makes eliminating them a priority. Ultraviolet light constantly disinfects the system, preventing microbial growth and contributing to fresh, clean air!

Destroying Airborne Bacteria and Viruses

Harmful pathogens that have made their way into your HVAC system are no match for UV lighting. It neutralizes these pathogens before they can reach the vents and spread in the populated areas of the building. This greatly reduces the risk of illness caused by such pathogens.

Reducing Allergens and Irritants

Dust mites and pet dander are experts at finding their way into every nook and cranny of a household, which could spell trouble for those with allergies to such particles. When they find their way into the vents and ducts, UV lights break these particles down. The result is a cleaner, healthier environment.

Minimizing Unpleasant Odors

We know things like killing viruses and allergens is a top priority when it comes to air quality, but minimizing odors is still important. Can you be truly comfortable when there’s a constant bad smell in the air? Probably not. The musty odors caused by things like bacteria, mold, and stagnant air will no longer torture you when you have an ultraviolet light installed in your system.

Additional Benefits of UV Lighting

We’re not finished with all the benefits this lighting can provide you! Here are a few more for your consideration:

• Improved Energy Efficiency: Clean coils mean improved airflow. Improved airflow means better system performance, resulting in the consumption of less energy. It’s good for the planet and your bank account!
• Extended HVAC Lifespan: With the prevention of microbial buildup, the major components of your system remain in optimal condition, which results in a longer lifespan for the equipment.
• Lower Maintenance Costs: Thanks to UV lighting, fewer contaminants are accumulating inside your system, and you won’t need to perform maintenance and repairs as frequently.

Are UV Lights Right for Your Home or Business?

UV lighting is great for air quality, but there are a few things to take into account before having one installed. Consider:

• The presence of mold, allergens, and respiratory concerns.
• The kind (and size) of HVAC system you have in your home or business.
• Your specific needs and sensitivities regarding indoor air quality. For example, what exactly are you allergic to?
