Average HVAC System Cost

While the average homeowner pays $5,000 to $15,000 on a new HVAC system, each system and home come with their own cost factors that shift the final price. We’ll go into more detail on each system further down, but the table below gives a snapshot of typical installed costs by system type.

System Type	Typical Installed Cost
Central forced-air system: furnace and central AC	$8,000 to $15,000
Air-source heat pump: ducted system	$4,500 to $12,000
Single-zone ductless mini-split	$3,000 to $7,000
Multi-zone ductless system: 2 to 4 zones	$8,000 to $20,000
Gas furnace replacement only	$3,500 to $8,000
Central air conditioner replacement only	$3,000 to $7,500
Geothermal HVAC system	$20,000 to $40,000

These figures cover both equipment and labour. Equipment-only pricing runs roughly 40% to 60% lower, but labour, materials, and permits make up the difference on most jobs.

Cost Breakdown for a New HVAC System

Several distinct cost components make up the total for a new HVAC installation. Understanding each one separately makes it easier to evaluate quotes and identify where there may be room to adjust the scope.

Labour

HVAC technicians in Canada typically charge $85 to $150 per hour. A standard replacement of an existing central system takes 8 to 16 hours of labour, putting the labour portion of the quote at roughly $800 to $2,500 for a straightforward swap. A full new installation including ductwork runs $4,000 to $8,000 in labour alone, sometimes more in dense urban areas where access and logistics add time to the job.

Equipment

The main unit is the largest single line item in most new HVAC system cost quotes. A mid-range gas furnace costs $1,500 to $4,000 before installation. A central air conditioner runs $1,200 to $4,500. Higher-efficiency models cost more upfront but attract utility rebates in many provinces and reduce monthly operating costs. For a full breakdown of furnace costs specifically, see our furnace installation cost guide.

Cost of materials

Beyond the main unit, a complete installation typically requires several supporting components:

• Refrigerant lines: required for central AC and heat pump systems
• Ductwork: new sections or modifications where the existing layout doesn't suit the new unit
• Electrical connections: wiring, disconnect boxes, and sometimes a panel upgrade
• Flue pipe or condensate lines: depending on the system type
• Thermostat: programmable or smart models are often included in quotes, though costs vary

Materials outside the main unit typically add $300 to $1,500 to the total, depending on what needs replacing or extending.

Existing Ductwork

Whether a home already has ductwork in place is one of the most significant variables in total HVAC system cost. A home with existing, well-maintained ductwork can accept a furnace or air conditioner replacement with minimal additional work, keeping costs at the lower end of the ranges above. A home without ductwork, or one where ducts need significant modification, adds $2,000 to $8,000 to the project, covering materials and labour for new duct runs, plenums, and registers. Ductless mini-split systems are often the most cost-effective route in homes where adding ductwork is impractical or expensive.

Size of Home

HVAC systems are sized in BTUs (British Thermal Units) or tonnes of cooling capacity. A commonly used starting point for Canadian homes is approximately 20 BTUs per square foot, adjusted for insulation quality, ceiling height, and window area. A 1,500 sq ft home typically needs a 2 to 3 tonne system, while a 3,000 sq ft home generally requires 4 to 5 tonnes. Each additional tonne adds roughly $500 to $1,000 to equipment cost. A qualified contractor should perform a Manual J load calculation to confirm the right size for your specific home rather than estimating from square footage alone.

Permits

Most Canadian provinces require a mechanical permit for HVAC installation or replacement. Permit fees range from $100 to $500 depending on the municipality, and some jurisdictions require an inspection before the system is commissioned. Ask any contractor specifically whether the permit is included in their quote and who is responsible for arranging the inspection.

Location

Labour rates vary across Canada. In major urban centres like Toronto and Vancouver, expect to pay 10% to 25% more for the same job compared to mid-sized cities like Calgary or Ottawa. Equipment pricing is largely consistent nationally, but shipping costs for specialty systems, particularly geothermal, can add to the total in remote areas. In remote communities where contractor availability is limited, many HVAC pros charge a travel fee on top of their standard labour rate, either as a flat fee of $100 to $300 or by billing travel time at their hourly rate from their base location.

Ongoing Maintenance

A new HVAC system needs annual professional servicing to stay under warranty and perform efficiently. Costs hover around $95 to $180 per visit, and what’s included depends on the system:

• Gas furnace: combustion analysis, heat exchanger inspection, and filter replacement.
• Central air conditioner or heat pump: refrigerant level check, coil cleaning, and electrical inspection on a similar schedule.

On top of annual service, filters should be replaced or cleaned every one to three months depending on the filter type and household conditions. Over a 15-year lifespan, routine maintenance adds $1,500 to $3,000 to the total cost of ownership, but skipping it is one of the most common reasons systems fail ahead of their expected lifespan.

Costs for Different HVAC Systems

The system type is the single biggest driver of total HVAC system cost. The four main options available to Canadian homeowners differ significantly in upfront price, operating cost, and suitability for different home types and climates.

Ductless HVAC System Cost

A ductless mini-split system pairs an outdoor compressor with one or more indoor air handlers mounted on walls or ceilings, providing both heating and cooling without any ductwork. It is a strong option for homes without existing ducts, as well as additions, finished basements, or properties where extending ductwork is impractical. The ductless HVAC system cost for a single zone runs $3,000 to $7,000 installed, covering the outdoor unit, one indoor head, refrigerant lines, and labour. Multi-zone systems with two to four indoor heads typically run $8,000 to $20,000 depending on the number of zones and the efficiency rating of the equipment.

Modern high-efficiency ductless systems operate at SEER2 ratings of 18 or higher and qualify for rebates through many provincial utility programs.

Geothermal HVAC Cost

Geothermal systems use the stable temperature of the ground to heat and cool the home, making them the most energy-efficient residential HVAC option currently available. The geothermal HVAC cost in Canada typically ranges from $20,000 to $40,000, with the variation driven primarily by the type of ground loop used.

A ground loop is a network of pipes buried underground that draws heat from the earth. The type used depends on your property:

• Horizontal loops are laid out across a wide area in shallow trenches and cost less to install, but require significant outdoor space.
• Vertical systems are drilled straight down and suit smaller lots, but the drilling adds to the cost.

Most urban and suburban homeowners end up with vertical systems for that reason, which puts total installation at the higher end of the $20,000 to $40,000 range.

Despite the high upfront cost, geothermal systems can reduce heating and cooling operating costs by 40% to 70% compared to conventional systems. In provinces with long heating seasons and rising energy prices, payback periods under 12 years are realistic for many homeowners.

Air-Source Heat Pump

An air-source heat pump transfers heat between indoor and outdoor air, providing both heating and cooling from a single unit. Modern cold-climate models operate efficiently at temperatures as low as -25°C, making them suitable as a primary heating source across most of Canada. Installed cost for a central ducted heat pump runs $4,500 to $12,000. A ductless heat pump costs $3,000 to $7,000 for a single zone.

For a full breakdown of what the installation involves and which rebates currently apply by province, see our heat pump installation cost guide.

Traditional Central System: Furnace and Central AC

The most common setup in Canadian homes is a gas furnace paired with a central air conditioner, both connected through a shared duct system. A mid-range installation of both units together typically runs $8,000 to $15,000. Replacing only the furnace costs $3,500 to $8,000, and replacing only the air conditioner costs $3,000 to $7,500.

High-efficiency models cost $500 to $2,000 more upfront but qualify for utility rebates and reduce annual operating costs. AFUE ratings of 95% or higher are considered high-efficiency for furnaces, while SEER2 ratings of 16 or higher apply to central air conditioners. For a detailed breakdown of central AC costs, see our central air conditioner cost guide.

When to Replace vs. Repair Your HVAC System

The decision to repair or replace directly affects total HVAC system cost, and getting it wrong in either direction is expensive. A few indicators that point toward replacement rather than repair:

• Age of the system: furnaces typically last 15 to 25 years, central air conditioners 10 to 20 years. A system approaching the end of that range is often better replaced than repaired
• Repair cost relative to replacement cost: if a repair quote exceeds 50% of the cost of a new system, replacement usually makes more financial sense, especially on older equipment
• Refrigerant type: systems using R-22 refrigerant have been phased out in Canada, and replacement parts are increasingly scarce and expensive
• Rising utility bills: if heating or cooling costs have increased steadily without a change in usage patterns, the system's efficiency has likely declined

If the system is under 10 years old and the repair is straightforward, repair typically makes more financial sense. A reputable HVAC contractor will give you an honest assessment of both options before recommending a direction.

How to Save on HVAC System Costs

While a new HVAC system is a significant cost for many homeowners, with a little planning, it’s possible to save money in the long run without sacrificing on quality of work. Here are a few ways to do so:

• Get at least three quotes: HVAC pricing varies significantly between contractors, and quotes on the same scope can differ by $2,000 or more
• Check provincial and utility rebates before signing: programs like Ontario's Home Efficiency Rebate Plus, BC Hydro's heat pump incentive, FortisBC rebates, and Hydro-Québec's LogisVert program can offset a significant portion of the cost for eligible high-efficiency systems, but most require pre-approval before work begins
• Consider a heat pump: in many Canadian provinces, cold-climate heat pumps qualify for substantial rebates that can bring the net cost below that of a traditional gas system
• Bundle the furnace and AC replacement: replacing both units at the same time typically costs less than replacing them separately, since the contractor mobilizes once and the ductwork connections are completed in a single job
• Time the installation off-season: spring and fall installations often attract lower labour rates than emergency replacements during peak summer or winter demand

HVAC System Cost: Frequently Asked Questions

How long does an HVAC system installation take?

A standard furnace or air conditioner replacement in a home with existing ductwork typically takes 4 to 8 hours. A full system installation including new ductwork can take one to three days depending on the complexity of the layout and the size of the home. Ductless mini-split installations run 4 to 6 hours for a single zone and 6 to 12 hours for a multi-zone system. Permits can sometimes extend the overall project timeline if an inspection is required before the system is commissioned.

Post your job on HomeStars to connect with HVAC pros near you who can give you a realistic timeline alongside their quote.

How long does an HVAC system last in Canada?

Gas furnaces typically last 15 to 25 years with regular maintenance. Central air conditioners average 10 to 20 years. Heat pumps fall in a similar range of 10 to 20 years depending on usage and climate. Geothermal systems’ ground loop component is rated for 25 to 50 years, while the heat pump unit itself has a lifespan comparable to conventional equipment.

Annual maintenance extends the life of any system, and a missed filter change or refrigerant leak left unaddressed shortens it.

What is the difference between AFUE and SEER2 ratings?

AFUE (Annual Fuel Utilization Efficiency) measures heating efficiency for gas furnaces and boilers. An AFUE of 80% means 80 cents of every dollar spent on gas goes toward heating the home. High-efficiency furnaces reach AFUE 95% to 98%.

SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling efficiency for air conditioners and heat pumps: a higher SEER2 rating means lower operating costs per hour of cooling. Current minimum SEER2 standards in Canada sit at approximately 13.4, while high-efficiency units reach SEER2 18 to 22.

Both ratings directly affect your utility bills and rebate eligibility.

Can I replace just the furnace or AC, or do I need to replace both at the same time?

You can replace either unit independently, and doing so is often the right call if one system is still well within its expected lifespan. That said, replacing both at the same time reduces overall labour cost since the contractor is already on-site and the shared ductwork is already open. It also avoids the scenario where a new, high-efficiency furnace is paired with an aging air conditioner that may need replacement within a few years.

A qualified HVAC pro can assess the condition and age of each unit and give you an honest read on whether replacing both together makes sense for your situation. Find pros near you on HomeStars to compare opinions and quotes before committing.

Can an HVAC system be financed?

Many HVAC contractors and manufacturers offer financing options, including zero-interest periods of 12 to 24 months on qualifying equipment. Some provincial programs also offer low-interest loans for eligible energy efficiency upgrades. If you are comparing quotes, ask each contractor what financing options they offer alongside their pricing, and factor in the total cost including any interest when comparing. Financing terms can vary considerably between providers, so it is worth reviewing them alongside the equipment and installation quote rather than treating them separately.
