Renting a Furnace in Ontario: The 15 Year Rental Bill Beside the Purchase Price

Billing & budgets · Published 2026-11-10 · Last updated 2026-11-10

General information only, not financial advice. Prices were checked on the date shown, are starting prices, and change by equipment, home, and promotion. Rental terms differ by provider and by contract. Read your own agreement, especially its buyout schedule and rate increase clauses, before signing, buying out, or selling your home.

$12,060 is the number that never appears in a furnace rental pitch. It is simple multiplication on the provider's own published figures, checked 2026-11-10: Enercare lists furnace rental in Ontario starting from $67 per month, and states that a rental lasts the life of the equipment, typically 15 years (s1). Sixty-seven dollars times 180 monthly payments is $12,060, before any rate increase. On the same page, the same company lists buying the furnace starting from $3,995, including standard installation and a one year warranty (s1). Both figures are starting prices, and both will move with the home and the equipment chosen. Held side by side, they are still the honest starting point the decision deserves.

The two offers, from one page

Read the table the way a salesperson would prefer you did not: the rental column is genuinely strong on service and genuinely open ended on cost. Both halves are true at once, and the sections below price each half separately.

The long run, flat, with its limits stated

The run below holds the $67 starting rate flat for the whole term. That is a labelled simplification, and it favours the rental: Ontario HVAC explainers note that rental rates typically increase year after year (s4), so a real agreement with annual increases totals more than the flat figure. Owner maintenance and repair costs on the purchase side are real too, and they are not in the $3,995; the table prices only the two published starting figures so the comparison stays traceable.

Two readings follow. First, cumulative rent passes the purchase starting price early: $3,995 divided by $67 is about 60 payments, so somewhere around year five the household renting at the starting rate has paid the purchase starting price in full, and keeps paying for roughly another decade. Second, the 15 year gap is about $8,065 at the starting figures, and that gap is the budget the purchase side has for maintenance, repairs, and even a mid life control board or blower motor before buying stops being the cheaper route. The rental's included maintenance, every two years on the Enercare terms (s1), is worth real money against that gap. It is not worth $8,065 of it on any ordinary reading, and a household should ask a quoting provider to price the included services explicitly if that claim is made.

What the rental genuinely buys

Renting is not a scam product; it is an expensive convenience product, and for some households the convenience is the point. The real benefits, on the published terms: no upfront payment when a furnace dies in January and the savings account is thin (s1), installation included (s1), maintenance included (s1), and repairs covered for the life of the equipment instead of arriving as surprise bills (s1). If rental equipment cannot be repaired, Enercare states it will replace the equipment under a new agreement at no cost under the current agreement, with terms and exceptions applying (s1). A household that values one phone number and zero repair risk, and that may move within a few years, is buying something real. The sections after this one are about making sure the price of that convenience is known before it is signed for, not about pretending the convenience is worthless.

The fine print that decides real cases

• The buyout is the exit price, and it is set by the agreement. Enercare's own answer on buying out mid agreement is to refer to the buyout terms in the rental agreement (s1). A Toronto guide verified November 4, 2026 reports Reliance's position that the buyout amount is based on the age of the unit, and advises getting a buyout quote before firming up any decision (s3). Ontario HVAC explainers put it more bluntly: buyout fees are often thousands of dollars, even on older equipment (s4).
• The monthly rate is a starting rate. Rental rates for heating equipment typically increase over time while the equipment itself is rarely upgraded (s4). Every increase widens the gap in the long run table above.
• Coverage has edges. Venting, piping, and system related repairs are usually not covered by rental agreements (s4), and providers rarely upgrade equipment unless it fails completely (s4). Included repairs means the repairs the agreement lists.
• A new agreement can restart the clock. Replacement of unrepairable rental equipment happens under a new agreement on the published terms (s1). Read any replacement offer as a fresh commitment, because that is what it is.

Before you sign: five checks

1. Get the full agreement, not the brochure. The company, the monthly charge, the start date, the term, what is covered, and how the buyout is calculated should all be on paper in your hands (s3).
2. Multiply the payment across the full term yourself. Monthly rate times twelve times the stated equipment life. Success looks like a total you have seen and accepted, not a monthly figure you have only heard.
3. Find the rate increase clause. If the agreement allows annual increases, rerun the total with one increase year included to see the direction, and ask what the last increase was.
4. Ask the year five and year ten buyout figures now. Buyout amounts are based on the age of the unit (s3), so a schedule exists. Success looks like two numbers in writing before the equipment is installed, not a phone quote years later.
5. Use the cooling off window if pressure got you here. The protections in the next section exist for exactly this situation.

What success looks like: a signed agreement whose full term total, buyout schedule, and increase clause you can each point to on the page, beside a purchase quote for the same home that you compared them against.

Buying or selling a home with a rental furnace

A rental contract does not disappear when a home is sold. Either the buyer takes the contract over, or the seller pays it out before closing, and the choice belongs in writing in the agreement of purchase and sale, with a copy of the actual contract obtained (s3). The transfer mechanics matter: on the Reliance handling the guide reports, the seller stays responsible for the agreement until it transfers, and once the buyer pays a first bill, the buyer has legally assumed the rental; for a furnace or air conditioner, the real estate lawyer helps the buyer sign an Assumption Agreement (s3). A buyer who inherits a rental without reading it inherits the remaining term, the current rate, and the buyout schedule together.

One 2024 change helps, within limits. On June 6, 2024, Ontario's Homeowner Protection Act banned registering a Notice of Security Interest, a NOSI, for consumer goods such as a furnace on a home's land title, and deemed existing consumer NOSIs expired (s2). An expired NOSI can still appear on title documents, but the land is not affected by it (s2). The limit is the sentence Ontario prints beside the ban: the ban does not cancel an existing contract (s2). The lien is gone; the payments, the term, and the buyout are not. Anyone who treats the NOSI ban as an exit from a rental agreement will learn otherwise at the buyout desk.

The protections that still apply after you sign

Ontario bars the pitch that starts at your door. Businesses cannot sell furnaces or water heaters door to door unless the consumer invited them; the ban on unsolicited door to door contracts took effect in March 2018 (s3). For contracts that do start at home, a 10 day cooling off period applies to door to door contracts (s3). Neither protection helps a household that never learns of them, which is why they sit in a money guide and not only in legal ones: a contract signed under pressure this week may still be a contract that can be cancelled this week.

Who should still rent, and who should buy

Rent when the furnace has failed, the money for a purchase genuinely is not there, and the alternative is financing at a worse rate or a winter without heat. Rent when a move within a few years is likely and the contract transfer is understood going in. Rent when one predictable payment with repairs included is worth a known premium to this household.

Buy when the home is a long term home, when a quote can be paid or financed at sane terms, and when the household can hold a modest reserve for the repairs ownership leaves with the owner.

The arithmetic at the starting prices is not close over 15 years: about $12,060 of flat rental payments against a $3,995 starting purchase price, before owner maintenance on one side and rate increases on the other. What renting sells is the removal of upfront cost and repair risk. Price that removal with the multiplication done, sign with the buyout schedule in hand, and the decision, whichever way it lands, is at least an informed one.
