How much does hvac cost in Markham?
Most Canadian homeowners spend $4,000-$7,000 to replace one major HVAC system - a high-efficiency gas furnace or a central air conditioner, installed. A simple like-for-like swap can start near $3,000, while premium modulating equipment or a large home pushes past $9,000. Whole-home cold-climate heat pumps and combined furnace-plus-AC projects run $8,000-$16,000 or more before rebates, and repairs, tune-ups and service calls are far cheaper at roughly $150-$1,500.
In Markham, ON, typical quotes tend to come in above the Canadian average, so the table below nudges these national figures up by roughly 15% at the low end of each range and up to 30% at the top end.
What moves the price: The low end is a tune-up, service call or simple like-for-like swap; the top end is premium equipment, new ductwork, or a whole-home cold-climate heat pump.
| Project | Typical cost in Markham |
|---|---|
| High-efficiency gas furnace replacement (installed) | $4,900-$8,500 $3,400 to $11,500+ per project |
| Central air conditioner installation (replacement) | $4,900-$8,500 $4,000 to $12,500+ per project |

| Whole-home cold-climate air-source heat pump (ducted or multi-zone) | $10,000-$19,500 $7,000 to $28,500 per project (before rebates) |
| New or full-replacement ductwork (whole home) | $5,500-$9,000 $2,900 to $15,500 per project |

What changes the price of hvac in Markham
- System size (BTUs / tonnage) - bigger homes need more heating and cooling capacity, so a 4-5 ton AC or large furnace costs more than a 2-ton or small unit.
- Labour and install complexity - labour is 40-60% of a typical install; tight access, long refrigerant line sets, electrical upgrades, or converting from one fuel type to another all push the price up.
- Whether the infrastructure already exists - adding AC or a furnace where there was none (new wiring, refrigerant lines, or ductwork) costs thousands more than a straight like-for-like swap.
- Ductwork condition - old, leaky, or undersized ducts may need sealing, resizing, or replacement, which adds to the total.
- Location, season, and rebates - big cities and remote/rural areas both raise prices, and peak summer (AC) or deep winter (furnace) demand lifts quotes; on the flip side, federal and provincial rebates - especially for heat pumps - can cut net cost significantly.
- Equipment efficiency and tier - a basic single-stage furnace or AC costs far less than a high-efficiency modulating or variable-speed model; stepping up to a premium unit can add $1,000-$3,000.
How hvac prices vary across Canada
Expensive metros cost more, and the difference is driven mostly by labour - HVAC labour is 40-60% of an install and runs about $80-$150/hr, at the top end in Toronto and Vancouver. A furnace tune-up that is roughly $120 in a mid-size Prairie city is $180-$220 for the same scope in Toronto or Vancouver. Big-city equipment prices are actually competitive because there are lots of contractors bidding; it is the labour-heavy portion of the bill that inflates.

Should I replace my furnace and AC at the same time?
If both are near the end of their life (usually 15-20 years), doing them together often saves on labour since the installer is already on site and the two systems share components. A combined furnace-plus-AC replacement typically runs about $8,000-$14,000 installed.
How much does it cost to replace a furnace in Canada?
Most homeowners pay about $4,000-$7,000 installed for a high-efficiency gas furnace. Simple like-for-like swaps can be closer to $3,000, while large homes, premium modulating models, or fuel conversions can push the total past $9,000.
Is a heat pump worth it, and what does it cost?
A ductless single-zone heat pump runs roughly $3,000-$6,000 installed, and a whole-home cold-climate system is typically $8,000-$16,000 or more. Federal and provincial rebates can offset thousands - sometimes cutting the net cost close to half - and because a heat pump both heats and cools, it can lower your year-round energy bills.
