New Furnace Installation Ontario: Rebates, Incentives, and Financing

If you live in Ontario, a furnace is not a luxury. It is the piece of equipment that determines whether your home feels tired and drafty by January or steady and comfortable through a -20 C snap. The moment you start pricing a replacement, you run into a thicket of model options, code requirements, and talk of rebates that may or may not still exist. The truth is more nuanced than a headline. Gas furnace rebates have been shrinking, heat pump incentives are expanding, and financing can be smart or predatory depending on how you structure it. This guide sorts the noise from what actually helps homeowners in Ontario, with a close eye on what I see daily in London and neighboring communities.

Where the incentives really are right now

Most homeowners asking about “furnace rebates” are surprised when I tell them that the largest incentives no longer target gas furnaces. Across Ontario, funding has pivoted toward heat pumps and building envelope improvements like insulation and air sealing. High efficiency gas furnaces were once rebated in the $200 to $500 range. Those days are largely over.

Enbridge Gas ran the Home Efficiency Rebate Plus program, tied to the federal Greener Homes program. As of early 2024, new registrations for that stream paused due to exhausted federal funding. If you were already in the system with a pre-retrofit audit, you may still complete your project and claim, but walk‑in eligibility for a new high efficiency gas furnace rebate is not something I would bank on. Manufacturers still offer seasonal dealer incentives, and local contractors occasionally sweeten packages with thermostats or extended warranties, but the big government cheques are reserved for projects that materially drop carbon emissions.

Heat pumps qualify because they move heat rather than create it, delivering two to three units of heat for every unit of electricity in moderate conditions. In a city like London, where winter lows often test equipment, a cold climate heat pump paired with a gas furnace in a dual‑fuel setup can reduce gas use substantially while keeping a familiar backup for deep cold. That combination tends to thread the needle, leveraging available incentives while maintaining resilience.

If you are set on a gas furnace, think in terms of long‑term operating cost and reliability instead of chasing legacy rebates. If you are open to integrating a heat pump now or later, you unlock better financial support and often a better year‑round comfort profile.

What to expect in London, Ontario

Homes in London span 1920s brick two‑storeys with fieldstone foundations, 1970s subdivision bungalows, and newer infill with spray foam and tight envelopes. Each behaves very differently under load. Sizing and ductwork condition vary widely, and that matters more than any brochure AFUE rating.

Design temperatures in this region hover around -21 C for heating load calculations. That is colder than many Ontario markets closer to the lakes but warmer than Northern Ontario. A right‑sized 96 to 98 percent AFUE furnace with an ECM motor, installed with proper combustion air and venting, will handle London winters without drama. Where homeowners get burned is when a replacement is sized only by matching nameplate to nameplate, ignoring changes like window upgrades or added insulation, or ignoring that the original was oversized to begin with.

The second London‑specific issue is basement humidity and leaky returns. Older homes often have panned joist returns that pull air from crawlspaces or gaps around the chimney chase. That setup quietly wastes money and strains equipment. If you are planning furnace installation in London Ontario, budget for at least minor duct sealing and return corrections. I have seen 10 to 15 percent efficiency gains from those fixes alone, which no rebate can match for simplicity.

For service, availability is strong in the city, and after‑hours furnace repair London Ontario calls are competitive. That keeps pricing honest. If a quote seems far out of line, you likely have options within a 20 minute drive who can deliver similar equipment and workmanship.

The current policy landscape in Ontario

Policy drives rebates, and policy has shifted. Here is the landscape as it stands through the 2024 to 2025 heating season based on public program status and what we see on projects:

Federal grants that once supported a wide range of upgrades paused new intakes in early 2024. Existing files can finish. New files cannot start under the same terms. The loan program that rode alongside the grants tightened eligibility at the same time, limiting access for brand new applicants.
Ontario utilities and partners emphasize load reduction first, then electrification. That means incentives have drifted toward air sealing, insulation, windows in some cases, and especially heat pumps. Straight furnace swaps seldom qualify.
Municipal programs vary. Toronto and Ottawa have well publicized low interest property‑assessed loans for energy improvements. Other municipalities are at different stages. London has been building out resources under the Better Homes umbrella and exploring financing options, but program terms change, and pilots come and go. Before you count on a municipal loan, confirm current availability with the city or a participating contractor.
Bill affordability programs, while not “installation incentives,” matter for many households. The Ontario Energy Support Program can reduce monthly electricity bills for eligible incomes, and the Low‑income Energy Assistance Program can help in emergencies. Neither pays for a new furnace, but both can stabilize cash flow when you are financing one.

Taken together, the message is practical: expect limited to no rebate for a standalone gas furnace. Expect better support for heat pumps and envelope work. Expect financing support to come more from lenders and contractors than from governments this year.

When a high efficiency gas furnace still makes sense

Even with the tilt toward electrification, there are many cases where a gas furnace is the right call in Ontario.

Rural properties without sufficient electrical capacity for a heat pump may face $2,000 to $6,000 in service upgrades before they can electrify. For an older farmhouse with leaky envelope and 140,000 BTU design load, a 97 percent two‑stage furnace paired with targeted air sealing can be the humane, cost‑rational decision now, with a plan to add a heat pump later when the envelope is improved.

Some condominiums and small commercial spaces have gas piping and flue runs that make a furnace or gas rooftop unit the only compliant option without major building modifications. In those cases, maximizing AFUE, confirming proper vent length and slope, and ensuring combustion air are the levers you can pull.

Homeowners on fixed incomes who are used to gas budgeting sometimes prioritize the lowest predictable monthly operating cost given current gas and electricity rates. Natural gas in Enbridge territory, after delivery and riders, often pencils out cheaper per unit of heat than resistance electric. A well tuned, right‑sized furnace can keep that monthly bill as low as possible for the setup you have.

The point is not to dismiss heat pumps, but to weigh building realities and finances. A mature contractor will design around your home, not a news cycle.

What a good Ontario furnace installation actually includes

I have walked into too many basements where a brand new 98 percent furnace was installed on top of a clogged return drop with no transition, undersized PVC venting, and sloped the wrong way. It ran, but it would never deliver the rated efficiency or lifespan. The equipment is only half the story.

Expect a proper load calculation under CSA F280, not a rule of thumb. In London, I see 100,000 BTU furnaces feeding 1,600 square foot homes that should have been 60,000 to 80,000 BTU. Oversizing sounds safe until you live with short cycling, cold corners, and noisy airflow. The right size runs longer, quieter, and dries the air better during shoulder seasons.

Ductwork should not be an afterthought. A new ECM motor will attempt to maintain airflow, but if the supply trunk is a bottleneck or the return is starved, static pressure spikes and the motor works harder. That increases electrical consumption and noise. Simple sheet metal corrections, a proper return drop with a turning vane, and sealing with mastic on the outside joints can change how a house feels. This is where a lot of the comfort magic hides.

Vent and drain details matter in a condensing furnace. The exhaust and intake lengths have maximum equivalent feet and specific slope requirements to prevent condensate pooling. The condensate trap should be accessible, and the drain should be protected from freezing where it penetrates a wall. Around London, where garages and unfinished basements can sit at 5 to 10 C, sloppy condensate routing is a common winter failure point.

Electrical work should be clean and inspected as needed. If you are adding a heat pump at the same time, expect a subpanel or upgraded breaker. Even for furnace‑only, a dedicated receptacle for the condensate pump and tidy low voltage wiring pays off during future service.

Finally, code and safety. In Ontario, gas work falls under TSSA oversight. Your installer should hold the appropriate G2 or G1 ticket, and the company should be registered. Some municipalities require a mechanical permit for furnace replacement, especially if ductwork is modified. Carbon monoxide alarms should be confirmed on all sleeping levels. If an installer shrugs at any of this, you have your red flag.

How much an Ontario furnace install really costs

Numbers vary by home and by contractor, https://lanemhgk842.capitaljays.com/posts/indoor-air-quality-upgrades-with-air-conditioning-installation-in-london-ontario but for a straight replacement with minor sheet metal, expect these ranges in Ontario:

Mid to high efficiency two‑stage or modulating furnace with ECM motor, installed: roughly $3,500 to $7,500 in most tract houses.
Premium modulating models with advanced controls, complex venting, or significant duct rework: $7,500 to $10,000 or more.
Add a cold climate heat pump in a dual‑fuel setup: typically $6,000 to $12,000 extra, depending on tonnage and electrical work.

Hidden costs tend to live in electrical upgrades, asbestos remediation on old duct tape and elbows, and in correcting unsafe venting from past renovations. On the operating side, natural gas pricing includes commodity, delivery, and fees. Depending on season and rate changes, total blended cost often lands in the 25 to 40 cents per cubic metre range. For a typical London home using 1,800 to 2,500 cubic metres per year, that is a few hundred dollars difference year to year as rates and weather swing. The federal carbon price on natural gas has been ratcheting up annually, so plan for gradual increases in operating cost over the life of the equipment.

These are reasons to model a few scenarios before you buy: straight furnace, furnace now with the panel sized for a future heat pump, or dual‑fuel immediately. The “cheapest today” option is not always cheapest over the next 15 years.

A practical path to incentives without wasting time

If you want to pursue whatever incentives exist without turning your renovation into a paperwork hobby, follow a clean sequence.

Decide on the scope first. If you will even consider a heat pump or envelope upgrades, design around that from the start.
Confirm program status in writing. Do not rely on last year’s blog post. Check the Enbridge website, NRCan notices, and your municipality’s program page.
If a program requires an energy audit, book the pre‑retrofit EnerGuide evaluation before work begins. Skipping this step voids many rebates.
Choose a contractor who handles the submission process. Good firms include photos, invoices, and model numbers that pass on first review.
Keep copies of everything. Serial numbers, AHRI certificates for matched systems, permits, and inspection receipts save headaches.

Five steps, no fluff. Most failed rebate attempts skip step three or choose a scope the program simply does not fund anymore.

Financing that helps, and financing that hurts

I see three broad financing paths on furnace installation Ontario projects. Each suits a different homeowner.

Bank financing through a HELOC or secured loan usually has the best rates and the most flexibility. You can bundle a furnace with insulation and windows, and you are not locked into a contractor. If you have equity and a reasonable plan to pay down the balance, this is the calm, boring option that wins over time.

Contractor financing is convenient, and sometimes manufacturers subsidize attractive rates during slow seasons. I have set up zero‑interest 12 month terms that let clients bridge to a tax refund or bonus. Read the fine print. Deferred interest offers can retroactively apply high rates if not paid in full on time. Longer terms often look friendly monthly and become expensive in total cost.

Rental and rent‑to‑own contracts tempt homeowners who do not want a credit check or who like the idea of “one monthly bill with service included.” The problems arrive later: escalator clauses, difficulty selling the home with a rental lien, and totals that often exceed the cost of purchase by several thousand dollars. Rentals make sense in narrow commercial cases or short‑term emergency situations. For most homeowners, ownership plus a service plan beats a rental.

If your goal is to pair a furnace with a heat pump and envelope work, look for low interest municipal property‑assessed financing where available. Toronto and Ottawa have established programs. London has explored options, and availability has fluctuated. If a program is not live in your city, it may not help your timeline. In that case, move to HELOC or contractor terms.

Choosing between one‑to‑one furnace swap and dual‑fuel

The comfort conversation is as important as the spreadsheet. A one‑to‑one swap is simple. Your ductwork, thermostat, and service routines stay familiar. A modulating furnace with a good ECM motor, paired with a variable speed fan setting and balanced ducts, will feel dramatically better than a single‑stage relic.

A dual‑fuel system adds capability. In spring and fall, the heat pump carries the load quietly, filtering the air and dehumidifying in shoulder seasons. Electricity prices vary by time‑of‑use, but you can program a switchover temperature where the gas furnace takes over as outdoor temperatures fall. For London, that point often sits between -5 C and -10 C depending on equipment and rates. You can tune it after living with the system for a few weeks.

If you plan to stay in your home for a decade or more, and if local incentives offset part of the heat pump cost, dual‑fuel earns a close look. If you plan to sell in two or three years, a clean furnace swap with visible quality workmanship and a transferrable warranty may be the wiser move.

The service side: repairs, warranties, and what matters after install

Furnace repair Ontario calls spike on the first cold week every year for predictable reasons. Dirty flame sensors, blocked condensate drains, failed pressure switches from improper venting, and plugged filters. A good installation sets you up to avoid most of these. A good service relationship catches the rest.

Look for warranties that split parts and labour. The manufacturer may offer 10 years on parts if you register within 60 days. Labour coverage depends on your contractor. In the London market, three to five years on labour for a premium install is common. Annual maintenance that is real, not a checklist on a clipboard, protects that coverage. That means combustion analysis, static pressure readings, drain cleaning, and software updates where applicable. If your contractor never pulls a manometer out of the truck, your furnace has not really been “tuned.”

For homeowners already using a local company for heating and cooling London Ontario needs, loyalty can pay. When the January cold hits, service slots go first to maintenance plan members. If your home is older and you know surprises lurk, priority service is not a sales gimmick. It is the difference between a same‑day pressure switch swap and a weekend with space heaters.

What to ask a contractor before you sign

The right questions save time. I bring these up even when homeowners do not, because every solid answer stacks the odds in your favor.

Will you perform a CSA F280 load calculation and provide the summary?
What static pressure did you design for, and will you measure post‑install?
What is the equivalent length of the venting, and how did you size it?
Are permits required in this municipality, and who handles them?
How are parts and labour warranties structured, and who registers the equipment?

Five questions, five clear answers. If any answer is vague, keep shopping.

Edge cases worth mentioning

Heritage homes with no returns upstairs often feel stifling even with a new furnace. This is not the furnace’s fault. You will need dedicated returns on upper floors or a separate small‑tonnage heat pump to manage bedrooms. I have also seen success with high‑low return grills and modest transfer grilles in doorways, but those are compromises.

Homes that have finished basements built around an old furnace may require creative sheet metal or partial framing removal. Budget for it. Rushing this stage gives you rattles, airflow restrictions, and future repair headaches.

If your gas meter or regulator is undersized for a new furnace plus other appliances, Enbridge will often adjust equipment at little or no cost if safety or service is at stake. Scheduling that visit can add a week. Plan this into the timeline if your existing furnace is barely hanging on.

New subdivisions sometimes have undersized returns by design, installed to keep builders’ costs low. If your filter looks like a sail after a day, you need more return, not a different furnace. This is a case where a slightly lower BTU furnace that can run longer and move air more gently will outperform a brute force larger unit.

Bringing it home for London and nearby communities

If you are replacing a furnace in London, St. Thomas, or the surrounding townships this season, shape your plan around realities on the ground:

Rebates for a standalone high efficiency gas furnace are slim to none right now. Do not let a phantom discount drive your decision.
Real value lives in sizing, duct corrections, and clean venting. This is comfort you can feel the first night.
If you aspire to a lower carbon footprint and want to harvest incentives, design for a dual‑fuel setup or prewire and panel‑size for a future heat pump. Even if you start with furnace only, spend a little on future‑proofing now.
Choose a contractor who can service what they sell. The best installation loses its shine without responsive furnace repair London Ontario support when a sensor fails at 9 pm in January.
Financing is a tool, not a plan. Keep total cost in view, use low‑interest options where you can, and be wary of rental contracts that look easy at the start and costly later.

For many households, the right move is a premium two‑stage or modulating furnace today, paired with targeted duct improvements and a smart thermostat. For others, it is the same furnace plus a cold climate heat pump and a serious look at air sealing. Either way, the best return comes from good design and careful installation, not from chasing yesterday’s rebate.

If you keep your focus on those fundamentals, your next winter in Ontario will be quieter, steadier, and cheaper to heat, whether your address sits north of the 401 or in the heart of the city.
