Henry Sapa founded Air Balance Group Inc. in 1992 in response to the needs of a rapidly developing city of Toronto. Bringing his own exceptional expertise in the areas of fluid dynamics and aerodynamics as they are applied in HVAC systems, Henry assembled a vibrant and diligent team of engineers and technicians, each of whom contributes a unique set of skills and experience.

Air Balance Group specializes in the testing, adjusting, and balancing of heating, ventilating, and air-conditioning systems (HVAC). While the company operates mainly in Southern Ontario, it has completed projects in more remote regions of the province as well, and, in fact, has traveled as far as Quebec, Newfoundland, Manitoba, and the Bahamas in order to take on challenging assignments in those locations.

With over 20 years of experience, Air Balance Group has completed more than 12,000 projects, and served over 500 clients. Dedicated to ensuring customer satisfaction, this team works to exacting standards on every project it undertakes.
