Heat Pump Rebate: Check Model Numbers Before a Substitution
A different heat pump model needs a fresh eligibility check. Use Hudson’s equipment record to compare the quote, proposed substitute and final installation.

If the heat pump on your installation proposal changes, check the replacement model before authorizing it. A familiar brand, the same advertised size or a similar-looking outdoor unit does not establish that the proposed system meets a particular rebate program’s requirements.
For homeowners preparing for Canada’s new $2 billion National Heat Pump Rebate, this is a useful habit to build now: keep one equipment record that follows the project from the original quote through any revisions to the final installation. Ask the contractor to explain every difference while there is still time to resolve it.
This guide focuses on that handoff. It includes a blank comparison worksheet, questions to ask about a substitution and a short message you can send to an installer. It does not verify any particular heat pump model or homeowner’s eligibility.
Where the new federal rebate stands
The October 8 federal backgrounder announces a $2 billion program for eligible electric cold-climate air-source heat pumps and says qualifying equipment must appear on an Eligible Products List.
An October 16 federal release identifies 2027 as the launch year, without specifying an opening day. The official campaign page still describes the rebate as upcoming and offers updates signup.
These announcements do not approve a specific system for your home. Do not treat a current Ontario product listing, an older federal grant table or a contractor’s estimate as confirmation under the forthcoming national program. Our federal-versus-Ontario guide explains the distinction.
Four different things an equipment document can tell you
When someone says a heat pump is “approved,” ask what has actually been checked. These are different questions:
| Question | Evidence to request |
|---|---|
| What equipment is being proposed? | Full model identifiers for the outdoor unit and relevant indoor components |
| Is this a certified equipment combination? | The applicable AHRI reference and certificate, with any exception explained |
| Does it meet this rebate program’s equipment rules? | A dated check against that program’s current requirements and product list |
| Has this project received the required approval? | The program’s application decision and any conditions that apply |
A fifth question remains for the contractor: whether the design suits your home. A product-list search cannot replace a site assessment or explain why that equipment was selected for your heating needs.
Use the word proposed until a decision is actually confirmed. This small distinction helps prevent a sales estimate from being mistaken for an approval notice.
Record the combination, not just the outdoor unit
For split systems, AHRI explains that certification covers the matched system. Its directory identifies the indoor/outdoor combination under a Certified Reference Number, and the corresponding certificate records the system’s ratings. It is therefore reasonable to ask for the combination behind the proposal, rather than accepting an outdoor-unit brochure alone. AHRI’s explanation of certified matched systems.
NRCan’s searchable heat pump list asks homeowners to obtain the brand, indoor and outdoor model numbers, AHRI number and furnace model where applicable. That is a useful identification checklist. However, this page retains Canada Greener Homes Grant wording: its historical grant amounts and process instructions are not the new national rebate’s rules.
Ask your contractor to put the complete identifiers into the proposal. If it says only “cold-climate heat pump” or gives a product family, request the missing details. If the final selection is still provisional, have that stated clearly and agree on when you will receive the completed schedule.
Keep model identifiers separate from serial numbers. The model identifies the product; the serial number identifies the particular unit delivered. Both can be useful in the final service record, but a serial number does not replace the model information needed to compare proposals.
Ontario example: a current list still has conditions
Ontario’s Home Renovation Savings heat pump page currently requires an active NRCan-listed model for a cold-climate air-source heat pump. It also requires a participating contractor and pre-installation approval. Those are Ontario program requirements, not confirmation of future federal eligibility.
The HRS program requirements PDF, marked May 2025 and still linked from the program’s terms page when checked, requires compatible components under the same AHRI number, subject to a “Coils Only” exception. That exception has conditions concerning the existing furnace and compatibility. Ask the participating contractor to document the applicable configuration; do not assume every existing furnace must appear on the certificate or that any furnace can be retained.
The HRS participant agreement also makes the application important: measures absent from it are ineligible, and a rebate is not guaranteed until written post-installation approval. Our practical recommendation: when equipment changes, ask how the application and approval need to be handled before work proceeds. Do not assume an automatic amendment process.
When the installer proposes a substitution
Consider this hypothetical situation: your quote lists one outdoor and indoor combination, but before installation you are offered a different indoor unit because of availability. The installer says it is equivalent.
That may be a workable alternative, but “equivalent” needs an explanation. Ask which characteristics are equivalent, which model identifiers change and whether the revised combination has been checked for the named program. You are asking the contractor to substantiate the change, not trying to redesign the system yourself.
Resolve these five points in writing:
- What changes? Identify every affected component, including equipment that stays in place.
- Why is it changing? Record the reason and any effect on price, timing or warranty.
- What is the revised design? Ask the contractor to explain any change to the proposed performance, controls or installation work.
- What supports rebate eligibility? Request the current program-specific check for the revised combination.
- What happens to the paperwork? Confirm who will update the proposal, application and final equipment record, where required.
A different model is not automatically a bad choice. The problem is accepting a change without knowing what it means. Avoid approving a substitution solely to keep an installation date if the incentive is essential to your decision and its status remains unresolved.
Use this equipment change record
Copy the table into an email or document and ask the contractor to complete the applicable rows. This is Hudson’s planning worksheet, not an official application or a list of confirmed federal document requirements.
| Record | Original proposal | Proposed revision | Final installation |
|---|---|---|---|
| Proposal date or revision | |||
| Outdoor unit: brand and full model | |||
| Indoor unit or units: full models | |||
| Furnace or air handler, if applicable | |||
| AHRI reference or documented exception | |||
| Program name and product-check date | |||
| Application reference and decision status | |||
| Price, timing or warranty changes | |||
| Person confirming the information |
Leave unresolved entries visibly unresolved. An empty model field should prompt a follow-up; it should not silently become the homeowner’s responsibility to guess.
Keep the original proposal and the revision instead of replacing one with the other. A dated sequence makes it easier to establish what was proposed, what you accepted and what arrived. For the wider price and scope comparison, use our heat pump quote worksheet.
Check the handoff before closing the file
Ask the contractor to walk you through the installed equipment schedule and point out the accessible identification labels. Request readable label photos for your records; leave access to electrical compartments and other technical checks to the installer.
Compare that schedule with the final accepted proposal. If an identifier differs, ask for an explanation and corrected records before treating the documentation as complete. A typo and a physical equipment substitution require different follow-up, so first establish which occurred.
For Ontario HRS, the program’s explanatory sample invoice calls for information including equipment make and model, AHRI number, capacity, itemized costs and payment status. Use the current program documents with your contractor to confirm the actual submission requirements.
For your own file, keep a final invoice, equipment schedule, warranty information and any program correspondence together. This also gives the next service technician a clearer starting point than a photo of the outdoor unit alone. Do not assume a final invoice, by itself, confirms a rebate award.
A message you can send before approving a change
Before I approve the proposed equipment substitution, please send the full revised indoor and outdoor model numbers, any relevant furnace or air-handler details, and the applicable AHRI reference. Please identify the rebate program you checked, the date of that check, and how the change affects any application or approval. Please also confirm changes to price, installation scope, timing or warranty, and provide the revised proposal for my records.
Adapt that request to your project. It is a practical information request, not a replacement for the terms of your agreement or the program administrator’s decision.

For updates on the forthcoming national program, join Hudson’s Heat Pump Rebate Interest List. It provides updates and guidance, not a government application, equipment approval or funding reservation. You can also follow the official federal campaign page for application announcements.
Frequently asked questions
Does an AHRI number guarantee a heat pump rebate?
No. AHRI certification identifies a certified equipment combination and its ratings. A rebate program has separate product, household, application and installation requirements. Ask for evidence for the specific program you intend to use.
What should I do if my contractor proposes a different heat pump model?
Request the complete revised equipment list, the reason for the change, a fresh program-specific eligibility check and written confirmation of how any application or approval is affected. Resolve those questions before authorizing the substitution.
Does Ontario eligibility prove eligibility for the new federal rebate?
No. Ontario’s Home Renovation Savings program and the forthcoming National Heat Pump Rebate have separate requirements. A product accepted under Ontario’s current rules should not be assumed eligible for the new federal program.
Can Hudson’s interest list approve my equipment or reserve a rebate?
No. Hudson’s interest list provides updates and guidance. It is not a government application, product approval or funding reservation. Equipment and project eligibility must be checked against the applicable program’s official rules.
