[PRESS RELEASE] Ultraviolet-C Light in Heating & Air Conditioning Systems Helps Kill Flu Viruses, Bacteria and Fungus


Trusted Heating and Cooling Company Offers Product Solution to Prevent the Spread of Viruses in Homes

Columbus, Ohio • March 13, 2020 – Dor-Mar Columbus Heating and Air today announced a solution that can help homeowners reduce the spread of viruses in their homes: Ultraviolet-C (UV-C) light units.

UV-C light systems have been around for years, according to Steven Brewer, third-generation owner of the family-run business. “These UV-C units are required in medical facilities around the country to prevent the spread of airborne viruses and bacteria through the ventilation system,” he said. “And they are 99% effective, according to our data.”

One of the problems with heating and cooling systems is that they recycle the same air throughout the home continuously, he said, so once bacteria or mold grows inside the ductwork or HVAC system, it pretty much stays there until it’s eradicated. And UV-C light is one of the best ways to do that.

UV-C light units are typically installed in the ductwork of a home’s HVAC system, in the plenum just above the evaporator coil on a typical gas furnace/central air unit. UV-C light impedes the growth of fungus and mold in the coil, kills bacteria, viruses and other microbial organic growth in the airstream by disrupting the DNA of the organism, preventing it from reproducing and attaching to healthy tissue.

In addition to viruses, bacteria and mold, UV-C light also works to eliminate volatile organic compounds (VOCs), potentially toxic chemicals created as a by-product of construction of the home. They also help to eliminate cooking and pet odors in the home.

Ultraviolet-C light systems can help keep your household and family safer by preventing the spread of flu, rhinovirus and coronavirus through the home’s heating and ventilation system. Coronavirus is a family of viruses that tend to spread quickly, and can be transmitted through the air.

The recent outbreak of COVID-C coronavirus worldwide has brought the family of viruses to light. Neither the Centers for Disease Control nor the World Health Organization has explicitly recommended UV-C light systems to specifically prevent the spread of the COVID-C virus, its widespread use in medical facilities throughout North America should lend credence to its effectiveness.

UV-C lights are a great start, but homeowners may want to also consider the following strategies:

  • Clean and seal ductwork to prevent recirculation of attic or crawlspace air within the HVAC system.
  • Frequently change your HVAC system’s air filters (i.e. monthly)
  • Control humidity with a whole-house dehumidifier or a variable-speed HVAC equipment

Why are these other items important? Leaky ductwork, high levels of unwanted air infiltration, or higher-than-wanted indoor humidity levels can cause air quality problems independent of what’s going on inside your HVAC equipment.

Mr. Brewer says he heartily endorses installing UV-C light systems to reduce the chance of spreading influenza, rhinovirus and coronavirus in a home or business. To determine if installing an affordable Ultraviolet-C lighting system is right for you, contact Dor-Mar’s friendly customer service team and we’ll arrange for a free evaluation and price quote.
