Quick Answer
A cold-climate heat pump in Ontario typically costs $6,000–$16,000 installed before rebates, depending on system size, whether it's ducted or ductless, and whether it replaces or works alongside your furnace. Rebates and low-interest loans through the Home Efficiency Rebate Plus and Canada Greener Homes Loan can cut thousands off that price, and lower running costs versus gas heating help recover the rest over time.
Heat pumps are the fastest-growing heating choice in Ontario because they heat and cool with one electric system and qualify for some of the largest rebates available. But the price range is wide — a basic single-zone ductless unit and a whole-home ducted cold-climate system are very different purchases. Here's what GTA homeowners actually pay and what moves the number.
Typical installed price ranges
- Cold-climate air-source heat pump (whole home, ducted): roughly $6,000–$16,000 installed before rebates, depending on capacity, brand tier, and electrical work needed
- Single-zone ductless mini-split: at the lower end of that range, often suitable for an addition, condo, or supplementing existing heat
- Dual-fuel (hybrid) setup — heat pump paired with a backup furnace: adds the furnace cost ($3,500–$7,500) on top, but gives you gas backup on the coldest nights
What drives the price
- System size — sized by a proper heat-load calculation, not square footage alone; oversizing wastes money and short-cycles
- Ducted vs. ductless — reusing existing ductwork is cheaper than running line sets to multiple indoor heads
- Cold-climate rating — true cold-climate units that heat efficiently at -25°C cost more than mild-climate models but are what Ontario winters require; see our cold-climate heat pump guide
- Electrical upgrades — some older homes need a panel upgrade to add a heat pump, which adds cost
- Backup heat — keeping your furnace as backup vs. going fully electric changes the equipment list
Rebates and loans that lower the cost
Heat pumps are eligible for the strongest incentives in HVAC. The Home Efficiency Rebate Plus offers rebates for qualifying cold-climate heat pumps when installed by a registered contractor after a home energy audit, and the Canada Greener Homes Loan provides interest-free financing to spread the remaining cost. Program rules and amounts change, so confirm current eligibility — our Ontario HVAC rebates guide tracks what's active.
Running-cost savings vs. a furnace
Because a heat pump moves heat instead of burning fuel, it can deliver two to three units of heat per unit of electricity, often making it cheaper to run than a gas furnace through much of the GTA's shoulder seasons — and it replaces your air conditioner, so you're buying heating and cooling at once. Whether the lifetime savings beat a furnace depends on your gas and electricity rates; we walk through the math in is a heat pump worth it for Toronto winters.
