Industry Credentials 


Design HVAC Experts live up their name with more certifications and projects delivered than any other Eastern Ontario HVAC Design Firm. Applying the theory and principals driven by HRAI (Heating, Refrigeration and Air Conditioning Institute of Canada) and ASHRAE (American Society of Heating Refrigeration Air Conditioning Engineers) our design services deliver ‘good engineering practices only’ without compromise. Building Code Compliance is mandatory but does not ensure comfort or energy efficiency. Our design services exceed building code without exceeding your budget.
