Professional Practice Advice on HVAC Modifications

Posted on August 4, 2020

Engineers and Geoscientists BC has updated its COVID-19 Practice Advice FAQ to include guidance on modifying heating, ventilating, and air conditioning (HVAC) equipment.

Appropriately designed and operated HVAC systems may reduce the airborne concentration of pathogens and microorganisms, and therefore lower the risk of transmission through the air. While research is ongoing, there is uncertainty about how COVID-19 is transmitted. The BC Centre for Disease Control should be consulted for up to date statements and guidance from health experts.

HVAC systems are technical and custom-designed for the building and spaces that they serve; any system modifications done by a person who does not understand the system and how it affects other building systems could end up doing more harm than good. HVAC systems should not be modified without assessment and involvement by an appropriately qualified and experienced engineering professional.

ASHRAE provides guidance on the design, operation, and maintenance of HVAC systems to help reduce the dangers of pathogen transmission through the air. Engineering professionals should consult the latest guidance from ASHRAE regarding COVID-19.
