Heating, ventilation, and air conditioning (HVAC) systems are essential in Canada's climate. Whether your furnace is failing, your central air is aging, or you want to switch to a more energy-efficient heat pump, understanding replacement costs helps you plan and budget — and take advantage of significant government incentives available in 2025.

Average HVAC replacement costs in Canada 2025:
Gas furnace (installed): $3,000–$7,000
Central air conditioner (installed): $3,000–$6,000
Furnace + AC combo: $6,000–$12,000
Air-source heat pump (installed): $5,000–$14,000
Ground-source (geothermal) heat pump: $20,000–$40,000+
Ductless mini-split (per zone): $2,500–$5,000

Gas Furnace Replacement

The gas furnace remains the most common heating system in Canada. A mid-efficiency furnace (800% AFUE) costs $2,000–$4,000 for equipment; a high-efficiency model (96–98% AFUE) costs $3,000–$5,500. Installation adds $1,000–$2,000 typically, bringing total installed cost to $3,000–$7,500.

High-efficiency furnaces cost more upfront but reduce your heating bill by 15–25% compared to an 800% furnace. In cold Canadian climates where heating costs are significant, the payback period is typically 3–6 years.

When to Replace Your Furnace

Central Air Conditioner Replacement

A central AC unit (paired with an existing forced-air furnace) typically costs $3,000–$6,000 installed. Size is measured in tons of cooling capacity — a typical Canadian home needs 2–3.5 tons. Look for a SEER2 rating of 14.3 or higher for good efficiency. Higher SEER2 (18–22) costs more upfront but reduces cooling bills.

Heat Pumps: The Growing Choice in Canada

Heat pumps have become increasingly popular due to their high efficiency and significant government rebates. A heat pump moves heat rather than generating it — making it 2–4x more energy-efficient than electric resistance heating and competitive with gas in mild climates.

Air-Source Heat Pump (ASHP)

Modern cold-climate ASHPs (e.g., Mitsubishi Zuba-Central, Bosch IDS) operate effectively down to -25°C to -300°C, making them viable across most of Canada. Installed cost: $5,000–$14,000 depending on capacity and brand. They provide both heating and cooling from a single unit.

Ground-Source (Geothermal) Heat Pump

Geothermal systems are the most efficient HVAC option available but require significant upfront investment for drilling or trenching. Total installed cost: $20,000–$40,000+. The Canada Greener Homes Grant provides up to $5,000 for ground-source heat pumps, and provincial programs may add further rebates.

Ductless Mini-Split

Mini-splits are ideal for homes without ductwork, for additions, or for zone-specific heating/cooling. Each indoor unit (zone) costs $2,500–$5,000 installed. A whole-home multi-zone system (4–6 zones) can cost $12,000–$25,000.

Canada Greener Homes Grant for HVAC

The federal Canada Greener Homes Grant offers significant rebates for heat pump installations:

To access these grants, you must complete a pre-retrofit EnerGuide evaluation before installation and a post-retrofit evaluation after. Provincial programs stack on top — in BC, the CleanBC Better Homes program offers an additional $1,000–$6,000 for heat pumps.

Financing Your HVAC Replacement

Several options exist for Canadians who need to replace HVAC systems:

Emergency replacement: If your furnace fails in winter, you may have limited time to shop around. Keep a list of two or three trusted HVAC companies in advance and know your system's age and model. An emergency call-out can add $200–$500 to the quoted installation cost.
