What a furnace rental usually includes
A rental is a long contract to use equipment you do not own unless you buy it out. The monthly rate usually covers the furnace and a standard installation, repairs and parts for the rented equipment, often an annual maintenance visit, and replacement if it fails beyond repair. It usually does not cover filters, work outside the standard installation such as ductwork changes, or equipment the contract does not name. Contracts can also be assigned, so the company collecting payments years from now may not be the one that installed the furnace.
Rent-to-own or ongoing rental? Some agreements hand you the furnace after the final payment; others keep billing as long as it stays in your home. That clause can change the 15-year math more than the monthly rate.
Questions that decide the real cost
Ask these before you sign a rental
- Can the monthly rate go up, by how much and how often? Get the figure in writing.
- Is this rent-to-own, or do payments continue after the term ends?
- Where is the buyout schedule, and what does each year's figure include?
- What exactly does the rate cover: repairs, parts, labour, maintenance, replacement?
- What happens if I sell the house, and will anything be registered against it?
- Is HST included in the quoted monthly rate?
How to read a buyout schedule
Most rental contracts include a schedule showing what it costs to buy the furnace, and end the contract, at each point in the term. The figure usually falls as the years pass. Three checks before you sign:
Compare the early years with a new furnace
A buyout near or above a new single-stage furnace at $4,000 to $6,500 installed means you are paying a premium for the financing built into the rental.
Check what the figure includes
Ask whether HST, administration or removal charges come on top.
Know what a buyout ends
Repairs and maintenance become yours. Ask what manufacturer warranty remains.
Selling a house with a rented furnace
A rental contract does not end when you sell. Usually the buyer takes it over, or you pay the buyout at closing. Buyers' lawyers ask about rented equipment, so tell your agent and lawyer early.
Notices on title
Some rental and financing companies used to register a notice of security interest (NOSI) on the title of homes with their equipment, and these surfaced when owners sold or refinanced. The Ontario government states that the Homeowner Protection Act, 2024 bans these notices for consumer goods such as furnaces, water heaters and air conditioners and treats existing ones as expired, while the contract itself still stands. It also warns about companies charging fees to remove notices that no longer have effect. Ask whether a company registers anything against your property, and check the current rules.

Door-to-door offers and your rights in Ontario
Since March 1, 2018, a business cannot sign you to a contract at home for a furnace, air conditioner, water heater, air cleaner or purifier, water treatment device or softener, or duct cleaning, unless you contacted it first and invited it over. That includes rentals and leases.
- A technician on a repair or maintenance call cannot sign you to a new contract for these products; they can only leave information.
- The province says a contract resulting from unsolicited door-to-door marketing is void, and you can keep the goods or services without obligation.
- Contracts signed at home carry a 10-day cooling-off period from when you receive a written copy; you can cancel without a reason. If installation happened in that window, rental payments or removal costs may still apply.
- Do not rely on a salesperson's word that your furnace or water heater is unsafe; a real hazard can be shown and documented.
Rules change, so confirm the current terms with Consumer Protection Ontario before you cancel or sign.

Financing: the third option
Financing, through an installer's lender, a line of credit or a personal loan, lets you own the furnace from day one without paying cash. The warranty and repairs are yours, and the payments end.
- Compare the interest rate and the total of all payments, not just the monthly figure.
- Read promotional offers closely: a low or deferred rate can jump if a balance remains when the promotion ends.
- Ask whether the lender takes security on the furnace and what happens if you sell early.
- The federal Canada Greener Homes Loan closed to new applications on October 1, 2025, so do not plan around it.
Replacing anyway? Price a cold-climate heat pump too. Eligible heat pumps can qualify for Ontario's Home Renovation Savings program with pre-approval before installation; a standalone gas furnace does not, and programs change. See Ontario HVAC rebates and furnace prices.

When renting can make sense
Renting can fit when
- You need heat now and have neither the cash nor the credit to buy.
- You value one fixed monthly cost with repairs covered over the lowest total.
- Maintenance and replacement are included, and any increases are small and written down.
Renting costs you when
- You stay for most of the term: the total usually passes the cost of buying.
- The rate rises every year, compounding over 10 to 15 years.
- You sell early and the buyer will not take over the contract.
- Billing continues after the term instead of handing you the furnace.
For owners who can pay cash or borrow at a reasonable rate, buying usually costs less over a full term. Renting is really a financing decision, so compare it with a loan. The furnace buying guide covers choosing the furnace itself.
Water heater rentals work the same way
Water heater rentals are common in Ontario and follow the same pattern: a monthly rate, a long term, a buyout schedule and a contract that follows the house. Buying a gas tank water heater typically costs $1,800 to $3,200 installed, and a tankless one $3,500 to $6,000, so run the same comparison before you renew. See water heater prices.
Questions people ask
How much does it cost to rent a furnace in Ontario?
Typically $40 to $80 a month before HST, on 10 to 15 year terms. The rate depends on the furnace, any bundled AC or water heater, and what the contract covers. Over a full term that is $4,800 to $14,400 before increases, so ask whether the rate can rise each year and by how much.
Is it cheaper to rent or buy a furnace?
Over a full term, buying usually costs less. A single-stage furnace costs $4,000 to $6,500 installed, and 15 years of tune-ups add $1,800 to $3,750. Fifteen years of rent at $40 to $80 a month is $7,200 to $14,400 before increases. Renting comes close only when the rate is low and fixed.
Can I get out of a furnace rental contract early?
Usually by paying the figure in the contract's buyout schedule, sometimes plus removal or administration charges. If you signed at home within the last 10 days, the cooling-off period may let you cancel. A contract that came from unsolicited door-to-door selling may be void; check with Consumer Protection Ontario.
What happens to a rented furnace when I sell my house?
The contract does not end with the sale. Usually the buyer agrees to assume it, or you pay the buyout at closing. Tell your agent and lawyer early, because rented equipment comes up in the buyer's due diligence, and ask the rental company whether anything was registered against the property.
Can a salesperson sign me up for a furnace rental at my door?
Not in Ontario unless you contacted the business first and invited it. Since March 1, 2018, businesses cannot enter contracts at your home for furnaces, air conditioners, water heaters and several related products without that invitation, and the province says contracts from unsolicited door-to-door marketing are void. You can ask the person to leave.
