Ontario Heat Pump Rebates & Incentives (2026)

Switching to a heat pump in Ontario can qualify for significant rebates on top of the savings our calculators show you:
Home Renovation Savings Program
Ontario’s current rebate program, delivered by Enbridge Gas and Save on Energy. A cold-climate air-source heat pump qualifies for up to $7,500, with no home energy assessment required for heat pump upgrades. Combined with other eligible upgrades (insulation, windows, solar), total household rebates can reach up to $12,000.
Note: the Canada Greener Homes Grant closed to new applications on October 1, 2025, and Enbridge’s earlier Home Efficiency Rebate+ program has also closed. Homeowners should apply through the Home Renovation Savings Program above instead it replaced both.
Rebate amounts and eligibility criteria change always confirm current details on the official program site before purchasing.

FAQ: AC and Heat Pump Calculators

How accurate are these AC and heat pump cost estimates?

Our calculators use current Ontario HVAC pricing data and are updated regularly. Estimates are intended as planning benchmarks actual contractor quotes may vary by 10–20% depending on your home conditions, local labour rates, and brand preferences.

Yes. Every calculator on this page factors in Ontario-specific inputs local hydro rates by utility provider, Ontario climate zones, and installation pricing from contractors serving Burlington, Hamilton, Oakville, Milton, Kitchener, Cambridge, and Brantford.

A traditional central AC only cools your home. A heat pump can both cool in summer and heat in winter, making it a more versatile, year-round option particularly popular in milder Canadian climates like BC and southern Ontario. Try our Heat Pump Size & BTU Calculator to see what fits your home.

It depends on your climate zone, existing heating system, and budget. Use our Heat Pump Recommendation Wizard or our “Is a Heat Pump Worth It?” quiz to get a personalized answer in under 2 minutes.

As a general rule, if your AC is over 10 years old and the repair cost exceeds 50% of the cost of a new unit, replacement is usually the better investment. Use our Repair Cost Calculator alongside the AC Cost Calculator to compare options.

In Ontario, a new central AC installation typically runs $3,500–$7,500 installed, while a heat pump installation typically runs $5,000–$12,000 depending on size and efficiency rating. Use the AC Cost Calculator or Heat Pump Cost Calculator above for a number specific to your home size and city.

Most Ontario homes spend $100–$250 per month running central air during peak summer usage, depending on your system’s SEER rating, home size,
and local hydro rate. Use the AC Operating Cost Calculator above to enter your own SEER rating and utility rate for a precise number.

We don’t have a dedicated ductwork calculator yet ductwork installation cost is factored into the estimate on our AC Cost Calculator, which accounts for whether your home needs new or modified ductwork as part of the AC installation.
