A new furnace is a major purchase, so it helps to know the numbers before you shop. In Mississauga, the price mostly comes down to the furnace’s efficiency and stage type, its size, and the brand you choose. This guide breaks down the real 2026 costs, what drives them, and whether it is smarter to buy, finance, or rent. Our furnace installation team quotes these systems across Peel Region every week.
The short answer: the new furnace cost in Mississauga is about $3,500 to $8,500 CAD installed in 2026, and most homeowners pay between $4,500 and $6,500 CAD for a mid-range high-efficiency unit. An entry-level single-stage furnace starts around $3,500 CAD, while a premium modulating model can reach $8,500 CAD or more. Your final price depends on efficiency, the size your home needs, the brand, and any ductwork changes.

New furnace cost by type
Ontario requires new gas furnaces to be high-efficiency, at least 95 percent AFUE, so the choice is mainly about stage type, which affects both comfort and price. Here are the typical installed ranges for a Mississauga home, verified July 2026.
| Furnace type | Efficiency | Best for | Typical installed cost |
|---|---|---|---|
| Single-stage | 95% AFUE | Tight budget, standard home | $3,500 to $5,000 CAD |
| Two-stage (most popular) | 96% AFUE | Quieter, more even heat | $4,500 to $6,500 CAD |
| Modulating (premium) | 98% AFUE | Steadiest heat, lowest bills | $5,500 to $8,500 CAD |
These ranges for the new furnace cost in Mississauga include standard installation and vary with brand, home size, and ductwork. Verified July 2026.
What affects the price
Several things move your quote up or down. Efficiency and stage type are the biggest, with modulating units costing more than single-stage. Size matters too, measured in BTU and set by a Manual J load calculation; an oversized furnace wastes fuel, so bigger is not better. Brand tier creates a real price swing between value and premium lines. Installation complexity adds cost when ductwork, venting, or an electrical change is needed, and replacing in the middle of a cold snap can add a seasonal premium. A proper in-home assessment is the only way to price your exact home accurately.
Costs beyond the furnace itself
A quote should be all-inclusive, but it helps to know what goes into it. Labour and installation typically make up 25 to 35 percent of the total, usually a one-day job of four to eight hours. Removal and disposal of the old unit, a permit where required, and basic venting are normally included in a reputable quote. Optional add-ons such as a new smart thermostat, a humidifier, or ductwork modifications add to the price. If you are replacing your air conditioner too, doing both at once saves on labour, permits, and disposal compared with separate visits.
Rent, buy, or finance?
You have three ways to pay, and the right one depends on your budget and how long you plan to stay. Buying outright is the lowest total cost over the furnace’s life and means you own the equipment. Financing spreads the cost into monthly payments while you still own the unit, which suits many homeowners. Renting has a low or zero upfront cost but the monthly fees, often 40 to 140 dollars depending on the unit, add up to more over 10 to 15 years, and rental contracts can complicate a future home sale. For most owners who plan to stay, buying or financing is the better value, though renting can make sense if you want the lowest upfront cost with maintenance included. We can walk you through all three with real numbers for your home.
Rebates and savings in 2026
Dedicated furnace rebates in Ontario ended in 2025, so there is no direct rebate on a standard high-efficiency furnace this year. However, if you are open to a heat pump, a cold-climate air-source model can qualify for up to 2,000 dollars or more through Ontario’s Home Renovation Savings program, plus interest-free federal financing, which is worth comparing at replacement time. A high-efficiency furnace also saves on its own: upgrading from an old 80 percent unit to a 96 percent model can cut gas costs by roughly 300 to 500 dollars a year, paying back part of the investment over time. Ask us about current offers and financing when you book.
How to get an accurate quote
The only way to know your real price is an in-home assessment. We measure your home, run a Manual J load calculation to size the furnace correctly, review your ductwork and venting, and then give you a written, all-inclusive quote with no hidden fees. We will present a couple of efficiency options so you can weigh upfront cost against long-term savings, and we can quote a heat pump alongside it if you want to compare. The decision always stays yours.

What is the most popular furnace for Ontario homes?
A two-stage 96 percent AFUE furnace is the most popular choice, costing about $4,500 to $6,500 installed. It offers quieter, more even heat and better fuel economy than single-stage, without the premium price of a modulating unit.
Are there rebates for a new furnace in Ontario in 2026?

Is it better to rent or buy a furnace?
For most homeowners who plan to stay, buying or financing costs less over the furnace’s life and means you own the unit. Renting has a low upfront cost with maintenance included, but the monthly fees add up over 10 to 15 years and can complicate a home sale.
