BEC HVAC Design has been serving Ontario homeowners since 1989. The company was founded and built over 20 years by a dedicated team that became synonymous with quality, precision, and genuine care for every client.
Today, BEC is proudly led by Diego — a BCIN-qualified HVAC designer and the new owner who took the reins from his mother, carrying forward everything she built. Diego works alongside the same trusted team that has been in the trade since day one, bringing decades of combined experience to every project.
What hasn't changed is what matters most: the same small team, the same commitment to quality, and the same genuine compassion for every homeowner we work with.
"We treat every home like it's our own. The same care and precision my mother brought to this work for 20 years is what we bring to every project today."
Established in 1989, we've designed HVAC systems for hundreds of GTA homes — from small additions to large custom builds.
Every design package meets Ontario Building Code requirements and is stamped for permit submission — no revisions, no delays.
We prefer meeting homeowners directly during the design process to ensure your comfort needs — not just code minimums — are the priority.
