HVAC Design Services in Oakville, Ontario

Ontario HVAC Design is headquartered in Oakville — our office is at 2275 Upper Middle Rd E, Suite 101, placing us directly in the community we serve most frequently. We work with Oakville builders, architects, and homeowners daily, and our drawings are accepted by Halton Region Building Services, which administers building permits for Oakville.

Oakville's residential market is dominated by high-value custom homes and executive subdivisions — particularly in North Oakville communities like Joshua Creek, Preserve, and Rural Oakville. These projects routinely require the full mechanical package: CSA F280-12 heat loss and gain calculations, fully ducted HRV design, and often SB-12 energy modelling for homes with extensive glazing. Many Oakville custom homes also include in-floor radiant heating and snow melt systems for driveways and front walks — services we provide as coordinated packages.

Oakville falls within CSA F280 Design Zone 6 (approximately 4,800 HDD), which sets the design outdoor temperature for heat loss calculations at -19°C for most of the town. Properties in the Escarpment area may warrant slightly more conservative assumptions. We apply the correct climate data for each specific project location.

Halton Region Building Services is generally well-organized and expects complete drawing packages. Our submissions routinely include stamped mechanical drawings, CSA F280 calculation reports, HRV design summaries, and Schedule 1 equipment documentation — everything required for a complete mechanical permit package without back-and-forth. We address any city comments and required revisions at no additional cost.

For commercial projects in Oakville, we handle HVAC design for medical offices, dental clinics, retail fit-outs, and small restaurant spaces. ASHRAE 62.1 ventilation compliance and OBC Part 6 requirements are standard for these projects, and we coordinate with architectural, structural, and electrical consultants as needed.
