Ontario HVAC Rebates 2026: Complete Guide to Heat Pump & Furnace Incentives

If you are a GTA homeowner thinking about a heat pump, furnace, or full HVAC upgrade in 2026, you are entering one of the most rebate-friendly windows Ontario has ever offered. Between the new Home Renovation Savings Program, the federal Greener Homes Loan, and Enbridge incentives, qualified upgrades can stack to over $12,000 in combined savings — but only if your installation is completed by a licensed contractor and registered correctly. This guide breaks down every active program, who qualifies, how much you can claim, and the deadlines you need to know.

Quick answer: the headline number for 2026 is up to $7,500 for cold-climate air-source heat pumps and up to $12,000 for ground-source (geothermal) heat pumps through Ontario's Home Renovation Savings Program. The program registration window closes May 31, 2026, after which no new applications are accepted for the season.

The 2026 Programs at a Glance

Home Renovation Savings Program (Ontario): up to $7,500 cold-climate ASHP, up to $12,000 GSHP, plus rebates on smart thermostats and other measures
Canada Greener Homes Loan: interest-free loans up to $40,000 for qualifying retrofits including heat pumps
Enbridge Home Efficiency Rebate Plus (HER+): legacy program — closed to new applicants Feb 5, 2024 (final post-retrofit assessments by Dec 1, 2025)
Oil-to-Heat-Pump Affordability Program (OHPA): up to $10,000 for homes converting from oil heating
Local utility rebates: smart thermostats, drain water heat recovery, and other measures from Alectra, Toronto Hydro, Enbridge, and others

Home Renovation Savings Program — The Headline Rebate

Launched in 2025 and running through November 2026, the Home Renovation Savings Program is a partnership between Save on Energy and Enbridge Gas, backed by the Ontario government. It replaced the old HER+ program for new applicants and pays directly for energy-efficient upgrades — most importantly heat pumps.

Heat pump rebate amounts depend on your existing heating fuel. Gas-heated homes receive $500 per ton; non-gas (electric, oil, propane, wood) homes receive $1,250 per ton. A typical 3-ton cold-climate ASHP in a Toronto home heated with electric baseboards could qualify for $3,750 — and stacking with the Greener Homes Loan keeps the upfront barrier minimal.

Eligibility Requirements (2026)

Be an Enbridge Gas residential customer with an active account heating with a natural gas furnace or boiler — OR be on the Ontario electricity grid heating with electricity, oil, propane, or wood
Live in a single detached, semi-detached, row house, townhome, or mobile home on a permanent foundation
Home must have been occupied for more than six months (new builds do not qualify)
Heat pump must appear on the Natural Resources Canada (NRCan) qualified products list
A pre-installation home energy assessment is NOT required if installing a heat pump as a single upgrade — a key simplification vs. older programs
Installation must be completed by a participating contractor

Stacking with the Greener Homes Loan

The Canada Greener Homes Grant closed to new applicants in 2024, but the interest-free Greener Homes Loan (up to $40,000, 10-year term) remains active and stacks with provincial rebates. For most GTA homeowners installing a heat pump in 2026, the practical playbook is: claim the Home Renovation Savings rebate to reduce the equipment cost, then finance the remaining balance with the Greener Homes Loan if needed. ZK Mechanical handles the rebate paperwork on your behalf as part of the install.

Hybrid Systems — Keep Your Furnace, Add a Heat Pump

You do NOT need to remove your gas furnace to qualify. Installing a hybrid system — a heat pump paired with your existing furnace — qualifies for the rebate while keeping gas backup for the coldest GTA nights when ASHP efficiency drops. This is often the best move for homes with a working but aging furnace: you get rebate dollars, lower carbon, and the comfort of dual-fuel resilience.

What About Furnaces, AC, and Water Heaters?

Direct rebates for traditional gas furnaces are limited in 2026 — the policy emphasis has shifted to electrification. However, the Home Renovation Savings Program does cover smart thermostats, attic insulation, and drain-water heat recovery alongside heat pump installs. Pairing a heat pump installation with these complementary upgrades stacks more rebate dollars in a single project. Replacing an old furnace with a high-efficiency model still pays back through energy savings even without a rebate — see our [furnace installation cost guide for the GTA](/blog/furnace-cost-gta-2026-complete-guide).

Critical 2026 Deadlines

Home Renovation Savings registration: closes May 31, 2026 — submit your project registration before then or no application will be accepted
Greener Homes Loan: open year-round (no current sunset), but program could change at any time
Enbridge HER+ (legacy): final post-retrofit assessments must be complete by Dec 1, 2025; final claims by Dec 31, 2025
Commercial/industrial Enbridge incentives (2026): equipment must be purchased between Jan 1 and Sept 30, 2026, and installed by Oct 31, 2026

How to Get the Most Out of Your Rebate

Use a participating licensed HVAC contractor — DIY installs do not qualify
Confirm the specific equipment model is on the NRCan qualified list before signing the contract
If you heat with electricity (no gas), prioritize cold-climate ASHP — your $/ton rebate is more than 2x what gas-heated homes receive
Get pre-approved for the Greener Homes Loan before equipment selection if you'll need financing
Stack: heat pump + smart thermostat + insulation in the same project to capture multiple rebate streams

Real-World GTA Example

A Mississauga homeowner with electric baseboard heat installs a 3-ton cold-climate ASHP through ZK Mechanical: equipment + install $14,500. Home Renovation Savings rebate (3 tons × $1,250 non-gas) = $3,750. Smart thermostat rebate adds another $75. Net out-of-pocket before financing: $10,675. Annual heating savings vs. baseboards: roughly $1,800. Effective payback under 6 years, with the unit covered for 10+ years on parts.

Common Mistakes That Disqualify Your Rebate

Buying equipment yourself and asking a contractor to install it — most rebates require contractor-supplied equipment
Installing a model not on the NRCan qualified list (especially imported brands)
Missing the project registration deadline (programs are first-come, first-served)
Combining incompatible programs in a way that breaks one of them — let your contractor structure the claim
Failing to keep itemized invoices — required for post-installation verification
