Published prices for an installed heat pump in Ontario run from $5,500–$14,000 for a standard ducted air-source system and $6,500–$20,000 for a cold-climate one, before rebates. A single ductless zone is $3,500–$8,500, and a hybrid with a gas furnace backup $11,000–$22,000.
These figures come from Ontario HVAC contractors’ own price guides, one of them in Hamilton. They’re ranges, not quotes: the size of the house, the ductwork and the electrical panel move the price.
Ducted heat pumps
A ducted heat pump replaces or sits beside your furnace and uses the existing ducts. Cold-climate models keep heating at lower outdoor temperatures and are the ones the rebate program covers.

Geothermal and the electrical panel
Ground-source systems cost the most because of the loop field. Older houses on 60 or 100 amp service sometimes need a panel upgrade for an all-electric heat pump.

Heat pump rebates
Ontario’s Home Renovation Savings Program pays for qualifying cold-climate air-source heat pumps by capacity. If you heat with electricity, oil, propane or wood it’s $1,250 per ton, up to $7,500; on Enbridge natural gas it’s $500 per ton, up to $2,000. A 3-ton system works out to $3,750 or $1,500. Ground-source systems get up to $12,000 ($3,000 on gas).
The unit must be on Natural Resources Canada’s qualified list, a participating contractor applies for you, and pre-approval is required: an install done before approval isn’t eligible.
Will it cost less to run?
It depends on what you heat with now and what you pay for it. Against propane, oil or electric baseboard a heat pump usually saves money; against natural gas at 2026 prices it usually costs more to run. Put your own bills into the heat pump vs gas calculator.
