Worked Quotes and Choosing a System
Financing a heat pump or furnace in Canada: loans, payment plans and on-bill options
Compare contractor payment plans, personal loans, lines of credit, municipal retrofit loans and mortgage options for HVAC in Canada, with worked costs and the traps to read for.
The cheapest way to pay for a new heat pump or furnace is usually cash or the lowest-rate secured borrowing you already have, such as a home equity line of credit, followed by a low-rate personal loan or a municipal retrofit loan if one exists where you live. Contractor and manufacturer payment plans can be competitive, especially promotional 0% offers, but they often hide admin fees, deferred interest or rates that jump after a promotion. A rental or lease is not financing at all: you pay for as long as the contract runs and you do not own the equipment. Before you sign, compare every option on the total amount you will pay, not the monthly figure.
This guide is part of how to compare HVAC quotes. The federal Canada Greener Homes Loan, which offered interest-free retrofit loans, is closed to new applications, according to Natural Resources Canada. Rates in the examples are illustrative.
The main options compared
| Option | How it works | Good for | Watch out for |
|---|---|---|---|
| Home equity line of credit | Secured, variable rate, borrow and repay freely | Lowest rate for many owners | Variable rate; interest-only minimums can stretch repayment |
| Unsecured personal loan | Fixed term and payment | Predictable payoff | Rate depends on credit; fees |
| Contractor or manufacturer plan | Arranged by the installer through a lender | Convenience, promotions | Admin fees, deferred interest, high post-promo rates, credit checks done at your door |
| Credit card | Revolving credit | Only for small amounts paid quickly | High rates |
| Municipal or local retrofit loan (PACE-style) | Repaid through property tax in some municipalities | Long terms tied to the property | Availability varies; may need to be repaid on sale; lender consent |
| Mortgage refinance or add-on at renewal | Adds to the mortgage balance | Low rate for large projects | Costs of refinancing; you pay interest for many years |
| Rental or lease | Monthly fee, provider owns equipment | Spreading cost with repairs included | Never-ending payments, buy-out formulas, removal fees; not ownership |
Worked example: four ways to pay $14,000
Illustrative only, using the HVAC financing calculator method.
| Option | Rate and term | Monthly | Total interest and fees | Total paid |
|---|---|---|---|---|
| Line of credit repaid over 5 years | 7.2%, 5 years | ≈ $279 | ≈ $2,710 | ≈ $16,710 |
| Personal loan | 8.99%, 7 years | ≈ $225 | ≈ $4,920 | ≈ $18,920 |
| Contractor plan, 0% for 12 months, then paid off | 0%, $395 fee | ≈ $1,167 for 12 months | $395 | $14,395 |
| Contractor plan, long term | 14.99%, 10 years | ≈ $226 | ≈ $13,090 | ≈ $27,090 |
The personal loan and the 10-year plan have almost the same monthly payment, yet the long plan costs about $8,170 more. The 0% plan is the cheapest if, and only if, you can pay about $1,167 a month and the contract does not charge deferred interest on the whole balance when a single payment is missed.
Waiting for a rebate
Most rebates are paid after the installation and paperwork, often weeks or months later. If you plan to use the rebate to pay down a loan, check whether the loan allows prepayment without penalty, and do not count on the rebate until it is approved. See the 2026 program guide.
Comparing financing with a rental
A rental may be offered at, for example, $120 a month for a heat pump or furnace with maintenance included. Over 15 years that is $120 × 180 = $21,600 before tax, plus any annual increases, and you still do not own the unit. If the same equipment costs $14,000 to buy and finance at 8.99% over 7 years, the total is about $18,920, after which you own it and pay nothing. The comparison is laid out in the rental contracts guide; also check whether the provider would register a security interest, covered in notices of security interest.
What to read in any financing contract
- The annual interest rate and the cost of borrowing in dollars. Provincial consumer protection laws require credit agreements to disclose these.
- Whether a promotional rate becomes a higher rate later, and whether deferred interest applies.
- Admin, setup or "processing" fees.
- Prepayment rights: can you pay off early without a penalty?
- Whether the loan is secured on the equipment or the house.
- Who the lender is. Contractor plans are usually provided by a separate finance company, and your rights and complaints go through that company.
Interest rate limits
Canada's Criminal Code sets a criminal interest rate. Since 1 January 2025 the limit is a 35% annual percentage rate for most consumer loans. Some provinces also regulate high-cost credit. Legitimate HVAC financing should be far below that limit; if a plan comes near it, walk away.
Mistakes to avoid
- Signing financing at the door before checking the price elsewhere. In Ontario, credit agreements tied to a prohibited door-to-door furnace or water heater contract are void; see door-to-door rules.
- Comparing monthly payments instead of total cost.
- Financing a heat pump with a payback longer than the loan term without knowing it. Check with the payback calculator.
- Forgetting tax: finance the after-tax total.
- Borrowing for a system that does not fit the house. Settle the size with the heat loss sizing guide and check the expected saving in the running-cost comparison before choosing how much to borrow.
FAQ
Is there still a federal interest-free loan for heat pumps?
No new Canada Greener Homes Loans are being approved. Check your province, municipality or utility for local financing.
Can I finance through my utility bill?
Some Canadian utilities and municipalities have offered on-bill or property-tax financing at times. Availability is local; ask your utility and city.
Does financing affect my rebate?
Usually not, as long as the equipment and paperwork meet the program rules. The program may require the invoice to show you as the purchaser.
