Home Furnace Fuel Type Price Comparison in Canada

If you’re shopping for a new furnace, one of the first questions you’ll face is: what type of fuel should it use?

The answer matters a lot—both for the upfront cost of the furnace and the long-term price of keeping your home warm. In Canada, the most common furnace fuels are natural gas, propane, electricity, and oil. Each has its pros, cons, and very different price points.

This guide breaks down the typical furnace prices, fuel costs, and the advantages and disadvantages of each type so you can make the best decision for your home.

Understanding Furnace Prices in Canada

The cost of a new furnace, including installation, usually falls between $4,000 and $6,500. Installation alone can account for over $1,000 of that total.

But keep in mind:

• The fuel type plays a big role in the final price.
• Your ongoing heating costs depend almost entirely on the fuel you choose.

It’s not always easy to compare fuel costs, since they’re measured in different ways—cubic meters for natural gas, litres for oil and propane, kilowatt-hours for electricity. Still, we can look at averages across Canada to give you a clear idea of what to expect.

What Affects Furnace Prices?

Several factors influence how much you’ll pay for a furnace in Canada:

• Brand and model
• Efficiency rating (AFUE or HSPF/SEER for heat pumps)
• BTU output (size of the furnace)
• Type of fuel (gas, propane, electric, or oil)
• Advanced features like variable-speed blowers or smart thermostats
• Installation and labour (prices are often lower in competitive markets like Toronto, Ottawa, Hamilton, and Kitchener-Waterloo)

Comparing Fuel Types for Furnaces

Here’s a breakdown of the pros and cons of each fuel type:

🔹 Natural Gas Furnaces

Pros:

• Cheapest fuel option in most parts of Canada
• Widely available in cities and towns
• Lower emissions compared to oil or coal
• No need for on-site storage

Cons:

• Not available in many rural areas
• Still produces greenhouse gases
• Requires professional hookup
• Small risk of carbon monoxide or gas leaks

---

🔹 Propane Furnaces

Pros:

• Cleaner-burning than oil and natural gas
• Ideal in areas without natural gas pipelines
• Efficient fuel that can also power other appliances

Cons:

• More expensive than natural gas
• Requires an on-site storage tank with regular refills
• Delivery and inspection add to costs

---

🔹 Oil Furnaces

Pros:

• Produces a large amount of heat (high BTUs)
• Works in areas without natural gas or propane service
• Long-lasting furnace units

Cons:

• High emissions and environmental impact
• Expensive fuel compared to gas and propane
• Requires a storage tank that can leak or corrode
• Fewer dealers and service providers compared to gas

---

🔹 Electric Furnaces

Pros:

• Nearly 100% efficient at converting electricity to heat
• Widely available everywhere in Canada
• Easier and often cheaper installation
• Lower maintenance needs
• Cleaner if electricity comes from renewable sources

Cons:

• Higher monthly heating bills in most provinces
• Doesn’t provide as much heating power as fossil fuels
• Can lead to uneven heat in very cold climates

Average Furnace Prices & Annual Heating Costs by Fuel

Natural Gas Furnaces

• Price: $4,000 – $8,000 (installed)
• Annual fuel cost: $1,155 – $1,680 (about $5.50 – $8.00/day in winter)

Propane Furnaces

• Price: $4,000 – $7,500
• Annual fuel cost: $2,000 – $3,000
• Best suited for rural areas without natural gas service.

Electric Furnaces

• Price: $2,000 – $7,000
• Annual fuel cost: $290 – $1,450 per month, depending on electricity rates
• More common in milder climates or as backup heating.

Oil Furnaces

• Price: $3,000 – $4,500+ (installed)
• Annual fuel cost: $2,000 – $5,500
• Still used in some regions, but less common today due to high operating costs.

---

Alternative: Wood-Burning Furnaces

Some rural homeowners opt for wood furnaces, especially if they have easy access to firewood.

• Price: $1,500 – $4,500
• Annual fuel cost: $800 – $3,200 (depending on supply and usage)

While they can be cheaper if wood is readily available, wood furnaces require more effort, regular maintenance, and don’t match the convenience or efficiency of modern gas or electric furnaces.

Key Takeaway

When comparing furnaces, don’t just look at the upfront price tag—think long term. A cheaper unit might end up costing thousands more each year in fuel bills.

• Best for affordability: Natural gas
• Best for rural homes: Propane
• Best for green energy users: Electricity
• Best heat output but costly: Oil
