HVAC Estimating Softwarefor Montreal Contractors
If you're bidding hvac in Montreal, the gap between a job that nets margin and one that doesn't usually comes down to undersizing equipment for actual load — and how you handle heavy snowfall requires robust snow removal planning. Drop a plan set in, walk away for 15 minutes, come back to a priced bid you can defend.
What Montreal does to a hvac bid
Cold winters with heavy snow, warm humid summers. Toronto, Montreal, Ottawa region.. Temperatures swing -15°C to 30°C (5°F to 86°F), rainfall runs 800-1000mm (31-39 inches), and inspectors here are working off OBC/NBCC Part 9. None of that shows up on a plan symbol legend — but it changes your fastener schedule, your waste factor, and whether the building department signs off on the rough.
Local Weather Challenges
- Heavy snowfall requires robust snow removal planning
- Freeze-thaw cycles damage foundations and driveways
- Ice storms can halt construction for days
- Short construction season (May-October)
Building Requirements
- Ontario/Quebec Building Code compliance
- Minimum R-60 attic insulation for new builds
- Foundation footings below frost line (1.2-1.8m)
- Triple-pane windows increasingly standard

Things that bite Montreal hvac contractors on the rough
Field-level notes for hvac work in Continental (Canada) conditions — anchored to OBC/NBCC Part 9.
Watch-out specific to this market
Undersizing equipment for actual load. In Montreal that gets worse because heavy snowfall requires robust snow removal planning, and OBC/NBCC Part 9 (frost line 1.2–1.8 m, R-60 attic, EnerGuide labelling, ice-and-water at eaves) won't let you patch around it after the fact. Catch it at takeoff or eat it on the punch list.
Forced air gas furnace most common. Cold climate heat pumps growing rapidly. HRV/ERV required in tight homes. Radiant floor heating popular in high-end builds.
High heating costs drive insulation upgrades
Heat pumps effective down to -25°C with modern units
Natural gas primary heating fuel
Net Zero Ready homes gaining popularity

Stuff Montreal hvac contractors ask before they sign up
Does this respect QC code, or do I have to re-cut every quantity?
Counts assume OBC/NBCC Part 9 (frost line 1.2–1.8 m, R-60 attic, EnerGuide labelling, ice-and-water at eaves). QC doesn't license hvac at the state level, so the variability comes from local amendments. Quantities are correct; you adjust crew rates and local permit assumptions in the bid summary.
How do you handle manual load calculations take forever?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For transit work in Montreal, the typical correction is one or two assemblies — not redoing the whole thing.
What about heavy snowfall requires robust snow removal planning?
Forced air gas furnace most common. Cold climate heat pumps growing rapidly. HRV/ERV required in tight homes. Radiant floor heating popular in high-end builds.
How much does a permit add to a hvac job around here?
