Nearly two years into the global Covid-19 pandemic and there is no end in sight.

Countries that were once free of the disease are locking down again as new strains take root. Some leaders are even saying we’ll have to get used to living with Covid, just like the common cold.

Until we squash this disease fully, it’s important everyone does their best to keep themselves safe. From gyms and swimming pools to home and the workplace.

HVAC and Covid

According to the U.S. Environmental Protection Agency, Covid can spread through droplets expressed while speaking, coughing, or sneezing. When this happens indoors, anyone in a six-foot radius may be at risk.

The particles also linger in the air longer than outside.

That means HVAC systems may prove key to stopping the spread of the disease.

ASHRAE Guidelines

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recently released guidelines to address HVAC and Covid.

These are important to keep in mind, whether you are an HVAC professional or looking to do work on existing units.

  • First and foremost, follow all public health and regulatory requirements. These are there for your safety.


  • When it comes to ventilation, outdoor airflow is key. Increasing the amount of external air brought in, versus just recirculating stale indoor air, helps keep the air clean. ASHRAE recommends also using a combination of high-quality filters and air cleaners. All of this should be done without increasing direct airflow onto any person.


  • For systems themselves, cleanliness and proper maintenance must be kept up. Temperature, humidity, and occupancy standards should be maintained as well. You should also be extra vigilant in ensuring systems are functioning as they are supposed to.
