Companies Making HVAC Adjustments To Try To Reduce Spread of Novel Coronavirus

The COVID-19 data is on track for New York City to enter Phase 4 on Monday, but it will do so without reopening indoor spaces like malls and museums as was previously planned. Governor Andrew Cuomo made that announcement on Thursday and didn’t offer a new timeline. While it is likely a disappointment to many hoping to get back to business, it will give shopping centers some more time to meet the state’s new HVAC requirements.

Earlier this month, Cuomo said that malls would be required to have an air filtration system with MERV-13 rating or the highest rating the system will allow–no less than MERV-11. It is believed that the higher level of filtration will reduce the rate of transmission of the novel coronavirus.

Companies in New Jersey have been converting their air filters to MERV-13, according to Air Systems Maintenance, Inc. sales manager Mark Attias.

Attias said the number of requests created a back order and delay in getting the filters. It also doesn’t work for every system.

“You can’t always do that with smaller systems,” he said. “Residential can’t always do it, because it disrupts the air flow too much. It has to be specially designed.”

The other “large-selling” item, Attias said, is UV lights. The lights go into the duct work and kill viruses in the air flow. Delivery of the lights was backed up as well, because of the number of orders.

There are other HVAC modifications that may be helpful as well, including changing the air flow.

As public health officials learn more and state governments move to open more businesses, as well as schools, there will be more demand for HVAC companies and supplies for system modifications.

HVAC Companies Likely To Be in Higher Demand with COVID-19 Requirements, Reopenings

As the tri-state area begins reopening businesses and camp facilities, HVAC companies are likely to be in high demand.
Youth camps in New Jersey, which can open on July 6, must meet specific HVAC requirements to get approval from the state to reopen their indoor facilities.
According to the NJ Department of Health summer camp standards document, “Camps must ensure that their indoor facilities have adequate ventilation, including operational heating, ventilation and air conditioning (“HVAC”) systems where appropriate. i. Recirculated air must have a fresh air component ii. Open windows if A/C is not provided iii. Filter(s) for A/C units must be maintained and changed according to manufacturer recommendations.”
And it won’t just be camp facilities keeping HVAC companies busy as states transition to the reopening phases for businesses and, eventually, schools.
American Society of Heating, Refrigerating and Air-Conditioning Engineers’ (ASHRAE) Epidemic Task Force member M. Dennis Knight recommends buildings where HVAC systems haven’t been running–or have been running minimally–since pandemic closures should replicate the process of new construction with regards to inspection, start up, and testing a system. He also suggested building owners recommission or retrocommission their systems. COVID-19 is not the only concern for restarting systems that have been down. There are always concerns for the integrity of a system after it hasn’t been running consistently or had proper maintenance, Knight said.
ASHRAE has put out building safe readiness and reopening guidance, as well as offering information on filtration and disinfection.
