Canada calculator
HVAC Replacement Cost Calculator
Estimate the cost to replace your home's heating and cooling system in Canada. Adjust the conditioned area, system type, efficiency tier, and whether you're replacing ductwork to see an itemised low–high range in Canadian dollars for your project.
How this calculator is built
Unit costs with sources
This model cites 3 sources across line-item unit costs, regional labor data, and tax references.
Regional labor adjustment
The province table applies local labor indexes only to labor-heavy line items.
Published methodology
The methodology page lists the formula, size drivers, labor model, and source links.

HVAC Replacement Cost by province: typical ranges
Each range applies that province's labor index to the labor-share line items of the default project; materials stay at national prices. Select a province for its full local breakdown and calculator.

Common questions
How much does it cost to replace an HVAC system in Canada?
HomeStars' 2026 guide puts a combined central furnace-and-AC system around $8,500–$20,000+ installed, so a mid-size home replacing both at high efficiency with the existing ducts reused lands near $14,250 before tax. A single unit, a ductless mini-split, or a standard-efficiency tier costs less. Use the calculator above for a range matched to your home size, system type, and efficiency. Prices shown are before GST/PST/HST, which is added per-province at billing.
Should I replace the furnace and AC at the same time?
If both units are near the end of their life, replacing them together is usually cheaper than two separate jobs — the crew shares one trip, one set of permits, and matched components run more efficiently. Choose 'Full system (furnace + AC)' to price both; pick a single component if only one unit has failed.
Which efficiency tier should I choose?
Standard efficiency is the budget choice; high-efficiency (higher SEER2/AFUE/HSPF2) is the durable mid-grade that lowers running costs in Canada's long heating season; premium variable-speed equipment sits at the top for comfort and the deepest energy savings. Pick the tier that matches your climate and budget — the calculator scales the estimate accordingly.
