Average HVAC Installation Costs in Canada

The HVAC system that will work best in your home will not work as well in another. The right setup will depend on factors like home layout and local climate. As such, pricing will vary across configurations.

The table below covers typical installed costs for the most common residential HVAC configurations in Canada. All figures include equipment and labour for a straightforward installation on a home with usable existing ductwork, except where noted.

System Configuration	Typical Installed Cost
Gas furnace only	$3,500 to $7,000
Central air conditioner only	$3,200 to $8,500
Gas furnace + central AC: existing ductwork	$6,500 to $12,500
Ductless mini-split: single zone	$2,000 to $5,000
Air-source heat pump: ducted, existing ducts	$4,500 to $10,000
Ducted HVAC system with full new ductwork	$10,000 to $20,000
Geothermal heat pump system	$20,000 to $40,000

One of the most common setups in Canada is a gas furnace paired with a central AC system. See our guides to furnace installation costs and central air conditioner costs for more details on both.

What Affects Your HVAC Installation Cost

System costs vary based on equipment choice, home conditions, and installation requirements. These are the main factors that influence pricing.

System type and efficiency rating

A standard gas furnace with central AC typically costs $6,500 to $12,500 installed. Upgrading to a two-stage or variable-speed system adds $1,500 to $3,000, but improves comfort and noise levels. Higher efficiency ratings increase upfront cost but lower energy bills over time.

Home size and load calculation

Correct sizing should be based on a Manual J calculation that considers insulation, windows, and layout. Relying on square footage alone often leads to oversized systems that short-cycle, increasing wear and reducing comfort.

Labour cost of installation

Labour represents 50% to 70% of total installation cost. Rates usually range from $75 to $150 per hour, with higher pricing in larger cities. More complex installs, such as tight spaces or older homes, increase labour time.

Ductwork condition and compatibility

Existing ductwork may need adjustments before new equipment is installed. Minor repairs cost $500 to $3,000, while full replacement can reach $5,000 to $12,000 depending on home size.

Permits and inspections

Most HVAC installations require permits, especially when gas, electrical, or refrigerant work is involved. Fees typically range from $100 to $500, and may or may not be included in the quote.

Rebates and incentives

Rebates can reduce installation cost, particularly for heat pumps. Some homeowners can benefit from the Oil to Heat Pump Affordability Program (OHPA), which offers up to $10,000 to switch from oil heating to electric heat pumps.

Provincial programs vary by region, so confirm current availability before planning around any specific figure.

HVAC System Types and What They Cost

Gas furnaces

A gas furnace is the most common heating system in Canadian homes. AFUE, or Annual Fuel Utilization Efficiency, measures what percentage of gas is converted to heat: an 80% AFUE furnace turns 80 cents of every dollar of gas into usable heat. Installed costs for a mid-efficiency gas furnace (AFUE 80%) typically run $3,500 to $5,500. High-efficiency models (AFUE 95% to 98%) run $4,500 to $7,000 installed.

Good to know: The higher upfront cost of a high-efficiency unit often pays back within five to eight years through reduced gas bills, depending on your province's gas rates.

Central air conditioners

Central AC units are the standard cooling solution in homes that already have a furnace. A 13 SEER2 central AC on a 1,500 to 2,000 sq ft home costs $3,200 to $6,000 installed. For homes in the 2,000 to 3,000 sq ft range, expect $5,000 to $8,500 installed for a properly sized unit.

Good to know: Similar to gas furnaces, high-efficiency models cost more upfront, but reduce cooling costs especially in regions with hot summers. Efficiency is measured using SEER2, or the Seasonal Energy Efficiency Ratio, a measure of how efficiently an AC unit cools over a full season: higher numbers (18+) mean lower operating costs.

Ductless mini-splits

Ductless mini-splits are the standard solution for homes without existing ductwork, additions, or rooms that a central system does not reach effectively.

• Single-zone system: $2,000 to $5,000 installed for one room.
• Two-zone system: $4,500 to $8,000 with two indoor units and one outdoor unit.
• Multi-zone system: $8,000 to $15,000 depending on number of zones and equipment quality.

Mini-splits avoid ductwork costs entirely, but the per-zone cost is higher than central systems at equivalent capacity.

Air-source heat pumps

Heat pumps provide both heating and cooling from a single system, making them increasingly common across Canada. Cold-climate heat pumps rated to -25 degrees Celsius or below are now available at price points that work for most Canadian homes.

An air-source heat pump on a home with existing ductwork costs $4,500 to $10,000 installed, depending on capacity and efficiency. In homes without ductwork, total costs can reach into the $10,000 to $20,000 range. See our heat pump installation cost guide for a full breakdown by system type.

Heat pump efficiency is measured using HSPF2 (Heating Seasonal Performance Factor 2): higher numbers mean lower operating costs.

Geothermal heat pumps

Geothermal systems use ground-source heat, which stays at a stable temperature year-round, making them highly efficient but significantly more expensive to install.

Total costs run $20,000 to $40,000 for a residential installation, with the ground loop accounting for the majority of that figure. Federal and provincial incentives can offset part of the cost, and payback periods typically fall in the 10- to 15-year range depending on local energy rates.

Geothermal is worth considering on new builds or major renovations where the ground loop can be installed before the landscaping is in place.

Heat recovery and energy recovery ventilators (HRVs and ERVs)

An HRV recovers heat from outgoing stale air and transfers it to incoming fresh air. An ERV does the same but also transfers moisture, which suits very tight homes that need to retain humidity in winter. HRVs and ERVs are now required in new residential construction across most Canadian provinces under current building codes. Installed cost typically runs $1,500 to $3,500, depending on capacity and whether existing ductwork can be used. If your HVAC quote does not mention ventilation, ask whether a unit is included or needs to be scoped separately.

Cost to Install an HVAC System with Ductwork

Installing a ducted HVAC system in a home without existing ductwork involves both mechanical installation and building modifications. Costs vary mainly based on home layout, accessibility, and the level of finishing required.

What ductwork installation involves

Ductwork installation includes designing and installing supply ducts, return ducts, and room vents, along with setting up the mechanical room for the furnace or air handler. In finished homes, it often requires opening walls or ceilings and completing repairs after installation. Proper load calculations are used to size the system to avoid noise, inefficiency, and uneven airflow.

Ductwork cost breakdown

Ductwork pricing varies primarily by installation difficulty and whether the home is already finished.

• New build or unfinished basement: $2,000 to $5,000 for a typical 1,500 to 2,000 sq ft home
• Partial retrofit in finished home: $5,000 to $9,000 when some access is available through basements, attics, or drop ceilings, reducing wall and ceiling work
• Full retrofit in finished home: $9,000 to $12,000+ when walls and ceilings must be opened, duct routes are complex, and full restoration is required

Installation cost increases primarily with the amount of demolition and reconstruction required, rather than the duct materials themselves.

Total installed cost with ductwork

When adding ductwork to a home currently without it, total costs vary considerably by system type and how much of the home is finished.

Scenario	Typical total cost
Gas furnace + ductwork (unfinished basement)	$7,000 to $12,000
Central AC + ductwork (existing furnace, no ducts)	$6,000 to $11,000
Furnace + AC + full new ductwork (finished home)	$14,000 to $22,000
Heat pump + full new ductwork (finished home)	$15,000 to $25,000

Overall cost is driven more by installation difficulty and home layout than by equipment alone. Homes that allow direct duct access remain significantly less expensive to convert than fully finished spaces requiring reconstruction.

Getting direct quotes from HVAC contractors who will inspect the home in person is the only reliable way to estimate these costs accurately, since no two homes present the same routing challenges.

HVAC Replacement Cost vs. New Installation

What a replacement typically includes

An HVAC replacement on a home with functional existing ductwork is significantly simpler than a new installation. Equipment disposal adds $300 to $600 to the total, depending on the equipment type and local disposal requirements. The ductwork is usually left in place unless inspection reveals damage or incompatibility with the new system's airflow requirements.

When replacement costs more than a direct swap-out

A straightforward furnace replacement runs $4,000 to $7,500 on a home where the existing ductwork is in good condition. Costs increase when:

• System size mismatch: the new unit is significantly larger or smaller, requiring duct modifications that add $500 to $3,000.
• High-efficiency flue conversion: switching from a mid-efficiency to a condensing furnace means replacing the chimney flue with PVC venting, adding $400 to $1,200.
• Electrical panel upgrade: older panels sometimes cannot support a heat pump or electric furnace without upgrading, adding $1,500 to $4,000. Read more on electrical panel upgrade costs.
• Refrigerant line replacement: older R-22 lines cannot be reused with modern R-410A or R-32 systems, adding $500 to $1,500 to the total.

For more detail on furnace-specific costs, see our furnace replacement cost guide.

Repair vs. replacement

A useful rule of thumb: if the repair cost exceeds 50% of what a new system would cost, and the equipment is more than 10 years old, replacement is generally the better financial decision. A furnace near the end of its 20-year lifespan that needs a heat exchanger replacement ($1,500 to $2,500) is worth replacing rather than repairing in most cases. Annual maintenance on a newer system typically runs $150 to $350, which is a reasonable ongoing cost to protect the investment.

FAQs: Your Questions About HVAC Installation Costs Answered

How long does HVAC installation take?

A standard furnace replacement where the existing ductwork is staying in place typically takes one technician four to eight hours, often completed in a single day. A combined furnace and central AC installation on the same home takes a two-person crew six to ten hours. Installing a full ductwork system in a finished home alongside the equipment typically takes two to three days, and finishing trades such as drywall patching may add additional time depending on how much was opened up during duct installation. Your pro should give you a timeline estimate at the quote stage.

Can an HVAC professional help choose the right system size?

Yes. An HVAC contractor will perform a load calculation and recommend a system size based on the home’s layout, insulation, and usage needs. This helps avoid oversizing or undersizing issues that affect performance and comfort. Pros on HomeStars can work with you on deciding what system is best for your layout, budget, and comfort.

Does HVAC installation include thermostat replacement?

In many cases, a new thermostat is included with a full system replacement, especially when upgrading to programmable or smart controls. However, some basic replacements reuse the existing thermostat if it is compatible. You can clarify with the pro you connect with on HomeStars if a replacement is included.

What warranty coverage comes with a new HVAC system?

New HVAC systems typically include manufacturer warranties that cover major components such as the furnace, air conditioner, or heat pump for a set period, often ranging from 5 to 10 years depending on the brand and model. Some contractors also provide separate labour warranties that cover installation work for a shorter period. Coverage details vary, so it is important to confirm both parts and labour terms before installation.
