Ontario HVAC Rebates 2025: How London Homeowners Can Save Up to $10,600

With Ontario's Home Renovation Savings Program, the Oil to Heat Pump Affordability Program, and Enbridge's OHR+ all active in 2025, London homeowners can stack up to $10,600 in rebates on a single heat pump upgrade. Here is exactly how to claim every dollar.

If you have been putting off upgrading your furnace or air conditioner because of the upfront cost, 2025 may be the year to act. Ontario homeowners currently have access to the most generous stack of HVAC rebates in the province's history. Between provincial, federal, and utility programs, a London homeowner installing a cold-climate heat pump can receive up to $10,600 back before factoring in long-term energy savings. This article breaks down every active program, the exact amounts available, and how to claim them without leaving money on the table.

Program 1: Ontario Home Renovation Savings Program (Up to $7,500)

The Ontario Home Renovation Savings Program is the province's flagship energy efficiency rebate, launched in January 2025 under a 12-year, $10.9 billion framework. It is administered through Save on Energy and Enbridge Gas, and it is open to all Ontario homeowners regardless of income. No energy audit is required for a single upgrade.

Up to $7,500 for a cold-climate air-source heat pump
Up to $12,000 for a ground-source (geothermal) heat pump
$500 for a heat pump water heater
$75 for an ENERGY STAR smart thermostat
Up to $8,900 for insulation (combinable with heat pump rebate)
$600 for a home energy assessment (required only when bundling 2 or more upgrades)

Rebates are paid within 30 to 60 days of an approved application. Your HVAC contractor must be registered with the program to submit on your behalf. Always confirm your contractor's registration status before booking.

Program 2: Oil to Heat Pump Affordability Program (Up to $10,000)

If your London home is currently heated with oil, this federal program offers the single largest rebate available anywhere in Canada: up to $10,000 toward the installation of a cold-climate electric heat pump. No energy audit is required, and the program is specifically designed to be accessible for low to middle-income households. The application process is straightforward and can be completed by your licensed HVAC contractor.

Your home is currently heated by oil, propane, or wood
Your household income falls within the low to middle-income threshold (see program guidelines)
You are installing a qualifying cold-climate air-source or ground-source heat pump
The installation is performed by a licensed contractor

Program 3: Enbridge Home Efficiency Rebate Plus (Up to $10,000)

Enbridge Gas customers in London and across Ontario can access the Home Efficiency Rebate Plus program, which provides up to $10,000 in rebates toward eligible retrofits. The program covers heat pumps, insulation, windows and doors, and renewable energy systems. Because this program is separate from the provincial Home Renovation Savings Program, some upgrades can be claimed under both programs, effectively doubling the rebate on qualifying work.

To stack Enbridge OHR+ with the provincial Home Renovation Savings Program, you typically need a pre-retrofit EnerGuide energy audit. Corner Gas HVAC can connect you with a registered energy advisor in London to get this done quickly.

Program 4: Canada Greener Homes Loan (Up to $40,000 Interest-Free)

While the Canada Greener Homes Grant closed to new applicants in 2024, the Canada Greener Homes Loan remains active in 2025. This federal program offers interest-free loans from $5,000 to $40,000 repayable over 10 years to help cover the upfront cost of major energy retrofits. Because it is a loan rather than a grant, it does not reduce the rebate amounts you can claim from other programs. It simply removes the barrier of having to pay the full installation cost out of pocket before receiving your rebates.

Program 5: Energy Affordability Program (Free Upgrades for Qualifying Households)

Income-eligible London households may qualify for entirely free HVAC-related upgrades through the IESO Energy Affordability Program. Qualifying homes can receive free smart thermostats, insulation, appliances, and in some cases a free cold-climate heat pump installation. There is no application fee and no repayment required. Eligibility is based on household income thresholds published by the IESO.

How to Stack Rebates: A London Homeowner Example

Here is a realistic example of how a London homeowner switching from a gas furnace to a cold-climate heat pump could combine programs in 2025. Assume a total installation cost of approximately $18,000 for a high-efficiency cold-climate air-source heat pump with installation.

Ontario Home Renovation Savings Program: up to $7,500
Enbridge Home Efficiency Rebate Plus: up to $3,100 (heat pump component)
Smart thermostat rebate: $75
Total potential rebates: up to $10,600
Net cost after rebates: approximately $7,400 on an $18,000 installation
Plus: long-term energy savings of $800 to $1,500 per year depending on your current fuel costs

Rebate programs change frequently. The amounts listed above reflect the programs as of April 2025. Always confirm current amounts directly with your contractor or the program administrator before making a purchase decision.
