BlogHVAC NewsSeptember 30, 2021Can The Coronavirus Be Spread Through An Air Conditioning System?

The short answer is yes, says Alan Wilson, Millian Aire’s Vice President of Technology and Training, especially in a home HVAC system. HVAC systems are built to circulate the air, which can include unwanted elements, even the coronavirus virus and its variants.

“That’s because an HVAC system, particularly in a residential setting, is meant to be a closed system,” adds Michael Stein, Millian Aire’s Director of Marketing & Analytics, adding that with such a system, the same air is circulating over and over in your home.

The good news is that there are strategies the experts at Millian Aire can employ to mitigate the spread of unwanted particles and substances in the air (including viruses), both Alan and Michael agree.

Mitigation Strategies

Millian Aire’s HVAC technicians can be brought in to provide any of the following value-added procedures to HVAC systems to decrease the number of particles that will be circulated. Click the headers for more information:

  • UV Lights
    These are installed in an HVAC system to denature (or break down) the protein of the virus so that it can’t replicate.
  • Air Purification
    Oxygen is used to neutralize Volatile Organic Compounds (VOC’s) in the air.
  • Filtration
    The size of most viruses is so small that normal filters can’t capture them, so they continue to circulate. But air cleaners (both standard and electronic) facilitate the capture of smaller particles.
  • Duct Cleaning
    Whether from dirty filters, leaking ducts, or age, ductwork eventually gets a build-up of dust and/or organic materials. Duct cleaning is a good way to remove this build-up and increase air quality. Bioesque Duct Sanitation is a product used by Millian Aire to sanitize duct work. Bioesque is free of bleach and other harsh chemicals, making it an ideal option for hazard-conscious or environmentally sensitive settings.
  • Needlepoint Bipolar Ionization
    This is a newer technology that can be used in HVAC systems or portable air cleaners to generate positively and negatively charged particles to facilitate surface disinfection or potentially help remove viruses.
  • More ventilation
    One of the simplest methods that can help disperse particles in the air is to have more ventilation outlets. However, this isn’t typically practical in a residential system, says Alan.

Standard Mitigation Strategies Remain First Line of Defense

Alan and Michael concur that the initial line of defense to minimize the presence or impact in a residence or facility of the coronavirus, which causes the deadly COVID-19 disease, is to adhere to scientific guidance by the CDC and other healthcare authorities.

However, if more advanced strategies are needed or desired to help optimize safety in a home or facility regarding the Coronavirus, reach out to Millian Aire’s air quality experts. They will be happy to put their more than 25 years of experience to work for you.
