What a heat pump costs in Ontario (2026)

Typical installed prices in the Hamilton area in 2026: a single-zone ductless mini-split $3,500 to $5,500; a cold-climate heat pump added to an existing gas furnace as a hybrid system $7,000 to $12,000; a whole-home ducted cold-climate heat pump with a new air handler, replacing the furnace, $9,000 to $16,000. Multi-zone ductless systems with three or four indoor heads run $9,000 to $15,000. Rebates, where you qualify, come off those figures afterwards.

What moves the price

• Capacity. Heat pumps are sized in tons or BTU; a 2 ton unit heats and cools a smaller or well-insulated house, 3 tons is common for a typical two-storey, 4 tons for a large or drafty one. Bigger costs more, and oversized is worse than right-sized because it short-cycles and dehumidifies poorly in summer.
• Cold-climate rating. A unit rated to keep its capacity at minus 15 costs more than a standard heat pump that fades at minus 5. In Hamilton the cold-climate unit is the one to buy; the cheaper one leans on electric backup and the bill shows it.
• Electrical. A heat pump needs its own 240-volt circuit, typically 30 to 50 amps. If the panel is full or is 100 amps with an electric range and a car charger, a panel upgrade is a separate job of $2,000 to $4,000.
• Line set and mounting. The insulated refrigerant lines run from the outdoor unit to the indoor coil; a long run or one through finished space costs more. The outdoor unit sits on a pad or a wall bracket above the snow line.
• The indoor side. A hybrid uses your existing furnace as the air handler and adds a coil on top. A furnace replacement at the same time, or a new air handler for an all-electric system, is the larger figure.
• Ductwork. A heat pump moves more air at a lower temperature than a furnace; ducts that were marginal for the furnace may need sealing or a larger return.

How much is a heat pump for a 2,000 square foot house?

A typical 2,000 square foot two-storey in the Hamilton area with average insulation needs a 2.5 to 3 ton cold-climate heat pump. As a hybrid on an existing furnace, expect $8,000 to $11,000 installed; as a whole-home ducted system replacing the furnace, $11,000 to $14,000. A heat-loss calculation, not the square footage, settles the size: two houses of the same area can differ by a ton depending on windows, insulation and exposure.

Who is eligible for the Ontario heat pump rebate in 2026?

Programs change, so confirm on the program site, but the pattern holds: you need an energy assessment booked before any work starts, a unit on the program list of qualifying cold-climate models, installation by a registered contractor, and a claim submitted within the deadline with the invoice and model numbers. Some programs are open to any homeowner; the larger amounts are reserved for lower-income households or for homes switching off oil or propane. Enbridge gas customers have had a separate route through the utility program. The current list is in the rebates guide, and we sequence the installation so the claim is valid.

What heat pump brands are being avoided in Canada?

The useful question is not which badge to avoid but which specification. Avoid any unit that is not rated for cold-climate operation, any unit without a published capacity at minus 15, any brand without a parts depot and service network in Ontario, and any quote that does not include the electrical work and the inspection. The major brands all make cold-climate models now; the cheap imports sold online without a local installer are the ones that end up on the repair truck. We install models we can get parts for the same week.

What is the downside to a heat pump system?

The purchase price above a furnace alone; air from the registers that is warm rather than hot; a higher electricity bill in a deep freeze if the system has no gas backup; and a lifespan of 12 to 15 years rather than the 15 to 20 of a furnace, because it runs all year. The hybrid answers the first three and the rebate softens the first.

How much should a heat pump installation cost, and how to compare quotes

Compare on the same basis: model number, rated capacity at minus 15, SEER2 and HSPF2 ratings, whether the electrical circuit and any panel work is included, the line-set run, the thermostat, the warranty on parts and on labour, and the permit and inspection. Three quotes for the same specification should land within a couple of thousand dollars of each other; one far below usually means a standard rather than cold-climate unit or electrical work left out.

For a written installed price for your house, sized from a heat-loss calculation, ask for a heat pump quote. The running-cost comparison against gas is in heat pump vs furnace in Ontario.
