MISSISSAUGA, Ontario - The Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) knows a thing or two about mechanical ventilation. Stringent building codes in Canada prompted the organization to develop its SkillTech Academy Residential Mechanical Ventilation Training program in 1983.
Since then, HRAI has trained and certified over 8,000 contractors, homebuilders, and building inspectors on the proper installation of ventilation systems.
