Frequently asked questions about heating & cooling in Montréal
- How much does a heat pump cost in Montréal, QC after rebates?
- Before rebates, $12,158 to $16,448 for a 3-ton cold-climate ducted system in Montréal, QC. Rebates vary by province and income: Ontario up to $7,500 for non-gas homes, BC up to $16,000 income-tested, Québec about $120 per 1,000 BTU/h, Manitoba $2,000. Net cost is commonly $7,000 to $14,000.
- Is a furnace and AC combo cheaper than buying separately?
- Usually by about $1,000, because the crew, permit and shared components are done once. Published Ontario ranges put a furnace plus AC combo at $9,000 to $13,000 for an average home.
- How big a heat pump do I need?
- It depends on the home's heat loss, not its square footage alone. Roughly 2 tons for a small bungalow, 3 tons for a 1,800 to 2,400 sq ft two-storey, 4 tons or more for larger or leaky homes. Ask for the calculation.
- Ductless or ducted heat pump?
- Ducted if you already have good ductwork from a furnace; it heats the whole house evenly. Ductless is cheaper per zone and suits homes without ducts, additions, or targeted rooms. Multi-zone ductless can cost as much as a ducted system.
- Do HVAC prices vary by province?
- Yes. BC tends to be highest for furnace installs, Ontario high for AC, Québec and the Prairies lower, and Atlantic Canada has the cheapest ductless installs at high volumes.
