Local HVAC contractor vs big rental company: who to hire depends on who installs the equipment, who owns it afterward and what the contract costs in total. Hire a licensed local contractor and own the equipment if you can pay or finance the purchase price, because rental payments on a water heater alone add up to two to four times its purchase price over 15 years. Rent only when you need no upfront cost and want repairs bundled in, and only after you have read the buyout table.
Who actually shows up to install the equipment
Ask this first, because the company on the contract is often not the company in your basement. Large rental firms commonly hand installations to subcontracted crews paid per job, which rewards speed. A local contractor's installer is usually the same person who comes back if something is wrong. Either arrangement can produce a good installation, so what you need is proof of who is responsible.
- TSSA contractor registration: a business doing gas work in Ontario must be registered with TSSA. Ask whose registration covers the job, the rental company's or the subcontractor's.
- The gas licence on site: the person connecting the gas and firing the appliance holds a G2 or G1 certificate. A G3 works only under supervision, so ask to see the card.
- Refrigerant handling: air conditioner and heat pump work needs a technician with an ODP card.
- Electrical: new circuits and disconnects fall under ESA rules.
- Insurance: ask for the liability certificate in the name of the company doing the work, not the brand on the flyer.
Checking is quick, and our guide on how to verify a TSSA licence shows where to look.
Rental-first quotes versus purchase pricing
A rental-first quote leads with a monthly payment and often leaves out the purchase price and the model number. A purchase quote leads with an installed price for a named model. You cannot compare the two until both are written on the same terms, so ask each company for the same five things.
- The brand and full model number of every piece of equipment, including capacity.
- The AHRI reference number for a matched air conditioner or heat pump.
- The installed cash price, with venting, any permit the job needs, thermostat and removal of the old unit listed.
- For a rental: the monthly rate, the annual increase clause, the length of the term and the buyout amount for each year.
- The labour warranty, in years, in writing.
Then do the arithmetic the brochure skips: the monthly payment times the months in the term, with the increases applied. A rented tank water heater at $25–$45 a month comes to roughly $4,500–$8,000 over 15 years, against $1,500–$3,000 to buy the same tank installed. A furnace or air conditioner follows the same pattern at larger numbers.
Buying does not have to mean paying cash. High-efficiency furnace installs run $4,500–$7,500, and contractor financing commonly lands at $60–$150 a month for a furnace or air conditioner. The difference is that a loan ends and the equipment is yours, which our answer on renting or buying a furnace in Ontario works through.
After the sale: no-heat calls, labour warranty and buyout terms
The rental's selling point is real: repairs are included for as long as you pay, with no bill for parts or labour. What differs is who answers the phone and how the contract ends.
Free quotes, written pricing.
- The no-heat call: a rental firm routes you through a call centre to whichever crew is available. A local contractor sends the shop that installed the unit. Ask each one what happens at 2 a.m. on a Sunday in January and whether there is an after-hours charge.
- Labour warranty: when you buy, the manufacturer covers parts and the contractor covers labour for a stated period. On a rental, the contract is the warranty, so read its exclusions for filters, ductwork, venting and water damage.
- Cancellation and buyout: every rental has a buyout schedule. Ask for the table before you sign, along with the removal fee.
- Selling the house: the buyer must agree to take over the rental, or you buy it out on closing.
- Ownership: rented equipment belongs to the rental company, so you cannot move it, modify it or have someone else repair it without their consent.
If you are already in a contract and want out, a furnace rental buyout starts with getting that buyout figure in writing.
Ontario rules that protect you with either company
Three provincial consumer rules apply whichever way you go. They stop the worst sales practices; they do not make a rental a good deal.
- Door-to-door sales: furnaces, air conditioners, water heaters and several related products cannot be sold at your door unless you initiated the contact.
- Cooling-off: a contract signed in your home can be cancelled for any reason during a 10-day period that starts when you receive a written copy of the agreement.
- Title registrations: Ontario's Consumer Protection Act now prohibits registering a notice of security interest against your home for consumer goods such as a rented furnace or water heater.
Rural Caledon and other lots past the gas main
On rural lots the standard rental package often does not fit the house. In rural Caledon, Campbellville, Kilbride and rural Flamborough, many homes sit past the natural gas mains and heat with propane, oil or electricity, with a private well for water. A rental program built around a natural gas furnace and a tank on municipal water needs changes for that house: a propane conversion, coordination with the propane supplier, and a water heater that copes with well water.
Ask a rental company whether the contract covers a propane-fired appliance and whether hard or sediment-heavy well water is excluded from the water heater coverage. A contractor who works those roads prices the conversion and the water treatment as part of the job. We cover that area from Burlington, and the Caledon service page lists what we do there.
Verdict: who should hire which
- Hire a local contractor and buy if you can pay cash or qualify for financing, plan to stay more than a few years, and want to choose the model.
- Use this test: add up ten years of rental payments. If the total is more than the written purchase price plus ten years of a maintenance plan at $150–$350 a year, buy.
- Rent if you cannot get credit, want one fixed payment that includes repairs, and have read the buyout table and the increase clause.
- Either way, refuse to sign on the first visit, and do not accept a quote without model numbers.

Frequently asked questions
Is it cheaper to rent or buy a furnace in Ontario?
Buying costs less over the life of the equipment in nearly every case. Rental payments continue for the whole term and usually rise each year, while a purchase is paid once or financed over a fixed period and then stops. Renting can still suit a household that cannot get credit and wants repairs included in one predictable payment.
Can a rental company put a lien on my house for a furnace?
Ontario now prohibits registering a notice of security interest on title for consumer goods, which was the tool rental companies used. That does not erase the contract. You still owe the payments or the buyout amount under the agreement, and the company can pursue that debt, so get the buyout figure in writing before selling or refinancing.
Can a local contractor repair equipment I rent from a big company?
Not without the owner's consent. Rented equipment belongs to the rental company, and its contract normally requires that their service network does the repairs. If you want a different contractor to look after the system, buy the equipment out first. After that it is yours, and any licensed technician can service it.
Do big rental companies use their own installers?
Some do, and many use subcontracted crews, sometimes both in the same region. The only way to know is to ask who will be on site, which company's TSSA registration covers the gas work and whose insurance applies. A reputable company of any size answers those questions in writing without hesitation.
