Can HVAC Maintenance Reduce COVID Risk?

Tragically, we have all been affected by this awful virus. It has changed our regular routines, in-home and in the office. For many, unfortunately, the very state of their being. Numerous states continue to work diligently to create plans to mitigate the spread and continue to find it challenging to do so securely without infringing on the rights of the people.

Recognizing the infection’s transmission is airborne, HVAC Unit upkeep is arguably more important than ever before, as it can help lessen the chances of further spread. The thinking behind this gains support by the fact that liquid and bacteria released into a unit go through a filtration process.

A recently published study from South Korea has dug deeper into the subject of Long-Distance Droplet Transmission of SARS-CoV-2. Finding that, under certain conditions, a droplet can be large enough to carry a viral load and small enough to travel 20 feet through the air. 

In other words, the more modest particles, which sometimes get referred to as bead cores, can stay suspended. You can read more about the study here.

Central air units that are well maintained gracefully clean the air, redirect polluted air and fumes it outside, replacing the air within with cleaner air from outside. 

What The Experts Are Saying:

Ventilation and filtration provided by heating, ventilating, and air-conditioning systems can reduce the airborne concentration of SARS-CoV-2 and thus the risk of transmission through the air.” 

  • The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) 

 

“SARS-CoV-2 viral particles spread between people more readily indoors than outdoors. When outdoors, the concentration of viral particles rapidly reduces with the wind, even a very light wind. When indoors, ventilation mitigation strategies help to offset the absence of natural wind and reduce the concentration of viral particles in the indoor air.”

  • The Centers for Disease Control and Prevention (CDC)

How This Info Can Help You: 

Introducing ventilation mitigation strategies help address a vulnerability commonly underestimated by many. 

Maintaining your system with approved filters can ensure occupant safety without compromising ventilation. The Minimum Efficiency Reporting Value rating, also known as the MERV rating, can be referenced to confirm compatibility with your unit. Also, to make sure you are getting the highest quality filters available other than HEPA filters. For the ultimate protection against dust, pollen, mold, bacteria, viruses, and the smaller airborne particles, a filter with a MERV rating of MERV 13-16 is what we recommend.

As we continue to learn new information about the novel virus and the long-term effects on patients who’ve recovered, the responsibility to take all essential safeguards lies with us. If you haven’t had an HVAC tech visit recently for scheduled maintenance, we strongly recommend that you make an appointment. Hopefully, sooner rather than later.
