Free furnace and free AC offers in Ontario come in three kinds, and only one of them costs you nothing. A 'buy a furnace, get an AC free' bundle carries the air conditioner's cost inside the furnace price. A 'free upgrade, no money down' pitch is almost always a rental contract that bills you monthly for ten years or more. The offers that are free are income-qualified programs from Enbridge Gas and Save on Energy, and their published upgrade lists cover insulation, draft proofing, thermostats and, for homes heated by electricity or oil, a heat pump: not a gas furnace.
Is There a Free Furnace Program in Ontario?
No. No government or utility program in Ontario hands a free gas furnace to homeowners at large, and no current program pays a rebate for a gas furnace on its own or a central air conditioner on its own. The rebates that exist are for heat pumps. They run through the Home Renovation Savings Program, need approval before the install, and need a contractor on the program's participating list.
So when a flyer, a phone call or a social media ad promises an 'Ontario free furnace upgrade', it is advertising something else: a bundle, a rental, or a lead form that passes your phone number to a sales team. The test is simple. Ask for the name of the program and look it up on the Enbridge Gas or Save on Energy website yourself. If the offer exists only on the seller's own page, it is a sales offer.
How a 'Buy a Furnace, Get an AC Free' Bundle Is Priced
The air conditioner in a free-AC bundle is paid for inside the furnace price. A condenser, an indoor coil, a refrigerant line set and half a day of labour have a real cost, and no contractor absorbs it. The published price bands for this area show where the money sits:
- High-efficiency gas furnace on its own: $4,500–$7,500 installed
- Central air conditioner on its own, with existing ducts in good shape: $3,500–$7,500 installed
- Furnace and air conditioner replaced in one job: typically $7,500–$11,500
- What doing both together honestly saves: $1,000–$2,500, because the crew, the sheet-metal work and the electrical hookup overlap
Here is the decision rule. If the bundle total lands inside or above that combined band, you are paying a normal price for both machines and the word 'free' is decoration. A bundle is a deal only when its total is lower than an itemized quote for the same two model numbers from another contractor.
How to Compare a Free-AC Bundle Against an Itemized Quote
Compare model numbers, not brand names. Every major brand sells an entry-level line and a premium line, and the unit given away in a bundle is usually an entry-level single-stage condenser at or near the 13.4 SEER2 legal minimum. Six checks settle whether the offer is a discount or a relabelled price:
- Ask for the full model numbers of the furnace, the outdoor condenser and the indoor coil, in writing.
- Ask what the furnace costs if you decline the air conditioner. If the price drops by thousands, the AC was never free.
- Take those model numbers to a second contractor and ask for the furnace and the AC as two separate lines.
- Check what the bundle leaves out: the coil, the line set, the outdoor pad, the thermostat, the electrical disconnect, removal of the old equipment and the permit where one applies.
- Check the size. A condenser picked to hit a price, with no heat-gain calculation behind it, is often the wrong tonnage for the house.
- Check the labour warranty on each machine, and ask who you call in year six.
Timing changes the answer too. If your air conditioner is under ten years old and working, a bundle makes you pay to replace a machine that had years left. A straight furnace quote will be lower than any bundle total, however the bundle is described.
'Free Upgrade, No Money Down' Usually Means a Rental Contract
A furnace or air conditioner installed for nothing is one you are renting. The company owns the equipment, you pay a monthly fee for a term that often runs ten to fifteen years, the fee rises on a schedule written into the contract, and leaving early means paying a buyout.
Free quotes, written pricing.
Water heaters show the math, because those figures are well known. A rented tank at $25–$45 per month adds up to $4,500–$8,000 over 15 years, two to four times the $1,500–$3,000 it costs to buy the same tank installed. Furnace and AC rentals follow the same pattern with larger numbers. For comparison, a $5,000 high-efficiency furnace financed over 10 years lands near $60–$75 a month depending on rate, and at the end you own it.
Before signing any rental, read four things: the length of the term, the annual increase, the buyout schedule, and what happens to the contract when you sell the house. Then ask a contractor what the same equipment costs to buy outright. Our comparison of a local HVAC contractor versus a big rental company covers that choice in detail.
Door-to-Door Furnace and AC Sales Have Been Banned Since March 2018
Nobody is allowed to knock on your door uninvited and sign you up for a furnace. Since March 1, 2018, Ontario's consumer protection rules have prohibited unsolicited door-to-door contracts for a specific list of household equipment and services:
- Furnaces
- Air conditioners
- Air cleaners and air purifiers
- Water heaters
- Water treatment devices, purifiers, filters and softeners
- Duct cleaning services
A contract signed through a prohibited door-to-door pitch is void, and the province says the consumer may keep the goods without obligation. A contract you sign at home after inviting the company in is legal, and it carries a 10-day cooling-off period that starts when you receive your written copy. Ontario's Homeowner Protection Act also prohibits registering a Notice of Security Interest, the lien that rental firms used to place on a home's title, for consumer goods.
If someone at the door says they are there to inspect your furnace, check your water heater or confirm your eligibility for a government upgrade, do not let them in and do not show them a utility bill. Our answer on cancelling a door-to-door HVAC contract in Ontario explains the steps if a contract is already signed.
The Programs That Really Are Free, and Who Qualifies
Two no-cost programs are open to Ontario households, and both are income-qualified. You apply to the program directly. Neither one works through a salesperson on your doorstep.
- Enbridge Gas Home Winterproofing Program: for income-qualified Enbridge customers whose home is heated by a natural gas furnace or boiler. It provides a free home energy assessment, wall, attic or basement insulation, draft proofing, and a smart thermostat for participants who receive insulation or draft-proofing work. Details are on our Home Winterproofing Program page.
- Save on Energy Energy Affordability Program: for income-qualified households, renters included. Its comprehensive support tier may include insulation, draft proofing, thermostats, energy-efficient refrigerators and, for homes heated by electricity or oil, a cold-climate air-source heat pump. Details are on our Energy Affordability Program page.
Income limits depend on household size and change from year to year, so read them on the official program page, not on a contractor's flyer. Notice what both lists leave out: a gas furnace replacement and a central air conditioner. A household that qualifies gets a warmer, tighter house and a lower heating bill, which is worth applying for on its own.
Verdict: Which 'Free' Offers Are Worth Your Time
- Income-qualified programs: yes. Apply directly through Enbridge Gas or Save on Energy if your household fits the criteria.
- Buy-a-furnace-get-an-AC bundles: sometimes. Treat 'free' as a discount claim and test it against an itemized quote for the same model numbers.
- 'Free upgrade' rentals: no for most homeowners. Buying outright or financing a purchase almost always costs less over the life of the equipment, and you own it when you sell.
- Anyone who knocks uninvited: no. The sale is prohibited and the contract is void.
If you have a bundle or rental offer in hand, bring it to the quote. We price the furnace and the air conditioner as separate lines with full model numbers, do a heat-loss calculation before recommending a size, and put the total in writing before any work starts, so the two offers can sit side by side. See what our furnace installation service includes, or book a free written quote and we will go through the paperwork with you at the kitchen table.
Frequently asked questions
Is the 'Ontario free furnace upgrade' ad on social media a real government program?
No. Those ads use government-sounding names to collect contact details for rental or financing sales. The real no-cost programs are the Enbridge Gas Home Winterproofing Program and the Save on Energy Energy Affordability Program. Both are income-qualified, both are applied for through the official program websites, and neither lists a gas furnace replacement among its upgrades.
Is a free air conditioner with a furnace purchase ever a real deal?
It can be a real discount, never a free machine. Doing a furnace and AC in one job saves the contractor labour, sheet-metal work and a second trip, typically $1,000–$2,500, and a bundle may pass that on. Test it by asking for the furnace-only price and an itemized quote for the same model numbers from a second contractor.
I signed a furnace rental contract at my door. What can I do?
If the salesperson came uninvited, Ontario treats a contract for a furnace, air conditioner or water heater as void, and you may keep the goods without obligation. If you invited them, you have a 10-day cooling-off period from the day you received your written copy. Put the cancellation in writing, keep a copy, and contact Consumer Protection Ontario if the company resists.
Can I get a rebate on a new gas furnace in Ontario in 2026?
Not for a gas furnace on its own. No current Ontario program pays a rebate for a stand-alone gas furnace or a stand-alone central air conditioner. Heat pump rebates run through the Home Renovation Savings Program, which requires approval before the install and a contractor on the program's participating list, so settle eligibility before you sign anything.
