Benefits of UV Lights for HVAC Systems

Published by Webmaster

Recently, there’s been a lot of buzz about using UV light for HVAC systems. Does it really live up to the hype? Here at WeatherWise Heating & Cooling in Crystal Lake, IL, we’ve experienced firsthand how beneficial UV lights can be. If you’re concerned about indoor air quality and your family’s health, it’s time to give UV lighting careful consideration. Used as a sterilizing agent for hundreds of years, UV light is an effective way to disinfect air and reduce the spread of germs.

Let’s explore the benefits of HVAC UV lighting more in detail:

UV Light Kills Bacteria, Viruses and Germs

Your HVAC system can be a blessing or a curse when it comes to infection control. For instance, if there’s mold or bacteria present in the system, air circulation can quickly spread it throughout the home. Studies by ASHRAE (The American Society of Heating, Refrigerating and Air-Conditioning Engineers) show the transmission of infectious airborne diseases like influenza and the common cold can be accelerated or controlled by a building’s HVAC equipment.

HVAC UV light disinfects the air by reducing and preventing microorganisms from circulating in the ductwork. Reduced microorganisms mean less transferred illnesses. UV lights focus on the coils in your HVAC unit, preventing the growth of fungi, mold, bacteria and pollutants like dust and soot. Without the UV light, these coils can become built up with contaminants. It’s easy to see why HVAC UV lights are adopted in hospitals and healthcare facilities.

HVAC UV Light Controls Mold and Other Allergens

In the same way UV light kills bacteria and viruses, it also eliminates allergens. If you suffer from allergies or asthma, you know just how important a home with clean, allergen-free air can be. With the right UV light in the right place, dust, mold and mildew can be eliminated. Say goodbye to HVAC fungal contamination. The cleaner the air, the less allergy-related symptoms like coughing, wheezing and sneezing.

HVAC UV Light Reduces Smells and Odors

No one likes a stinky home or workplace, but there may be something more dangerous lurking beneath an unpleasant odor. Some airborne contaminants are hazardous, containing over two to five times more contaminants than outdoor air.

VOCs (Volatile Organic Compounds) are odor causing chemicals like those from tobacco products, perfume, hair spray, paint, glue and cleaning supplies. According to the EPA (Environmental Protection Agency,) VOCs contribute to health problems like headaches, nausea and sinus irritation. Using a UV light in your HVAC system is a simple way to remove VOCs and clean your air.

I've been using WeatherWise for years and always happy with the service.

They are always on time and best of all, reasonably priced. It's hard to find a company in that industry that you can trust. They have been there when I needed them. I trust WeatherWise and have recommended their service for my neighbors who are also very happy. I recently had them install a new furnace and air conditioner and was surprised that both were installed in less than a day. Keep up the good work!

I had weather wise come out to my home to put on a new humidifier.

They completed the job quickly, professionally, and explained how everything worked to me and my husband. When the crew was finished, they left our basement neat, clean and tidy. For the price, you really can't beat their great service!

Weatherwise is amazing.

I can tell you that these guys really know what they are doing, they are priced very fair, and treat you like friends and family. Of all the service companies I have dealt with in my time they are by far the best. Frank, on behalf of my family and my self we thank you from the bottom of our hearts for your service. A new furnace 2 days before -25 degree temps is a huge relief. Thanks again and we will see you next fall for service.
