Yes, a heat pump can replace your furnace, and in many Canadian homes it can do it completely. Whether it should do it alone or share the work with a backup furnace depends on your climate, your electrical panel, your ductwork and what you pay for the fuel you use now. The safest way to get those answers is a heat-loss calculation by a licensed installer, and we connect you with vetted, licensed, insured contractors who do that work for rebate-ready installs.
TL;DR
- A cold-climate heat pump can fully replace a furnace in many homes in coastal British Columbia and parts of Southern Ontario. In the Prairies or inland regions, a hybrid setup that keeps the furnace may suit better.
- Before you commit, check three things: sizing (a heat-loss calculation), electrical capacity and ductwork.
- Savings depend on the fuel you replace and local electricity rates. Oil and electric-resistance homes tend to gain the most.
- Federal and provincial rebate programs change. Confirm what is open on the official page before you sign a contract.
- Pick a contractor who is licensed, insured and familiar with rebate paperwork.

Can a heat pump really replace a furnace in Canada?
A heat pump moves heat instead of burning fuel to make it. In winter it pulls heat from outdoor air and moves it inside; in summer it runs in reverse as an air conditioner. That is why one unit can replace both your furnace and your central AC.
Cold-climate models are built for our winters. Efficiency Canada reports that advanced heat pumps can work down to around −30°C, although efficiency drops as temperatures fall. The same publication says heat pumps can operate without backup for more than 90 per cent of the heating season even in Canada's coldest cities.
So there are two realistic setups:
- All-electric: the heat pump handles everything, sometimes with electric resistance elements for the coldest hours. This is the usual answer in milder regions.
- Hybrid (dual-fuel): the heat pump does most of the heating and your existing furnace takes over below a set outdoor temperature. In one Ontario home case study, the existing furnace served as backup below about −10°C.
In modelling of Ontario homes filed with the Ontario Energy Board, a hybrid system with a high-efficiency furnace was the most cost-effective option in Toronto, Ottawa and Thunder Bay, while a cold-climate heat pump on its own came out ahead in Windsor. Your own house will sit somewhere on that spectrum.
What you are replacing changes the answer
The type of furnace you have now matters more than anything else for your bills.
Oil furnace to heat pump
This is where the savings tend to be largest, because heating oil is expensive per unit of heat. As of February 2026, households in the federal Oil to Heat Pump Affordability program saw average annual energy savings of $1,377. Your result depends on your oil price, your electricity rate and your house.
Gas furnace to heat pump
Natural gas is cheaper than oil in most provinces, so the bill comparison is closer. A C.D. Howe Institute study found that relative fuel prices are critical to the decision: if gas stays cheap against electricity, going fully electric could raise bills, and dual-fuel systems can make sense in the medium term. A gas furnace swap is also the case where you gain the most in comfort, since the heat pump adds efficient air conditioning.
Electric furnace or baseboards to heat pump
Electric furnaces and baseboard heaters turn one unit of electricity into one unit of heat. A heat pump delivers several units of heat per unit of electricity, so this is often the biggest drop in electricity use. With an electric furnace you already have ducts, so a ducted heat pump is usually straightforward. With baseboards there are no ducts, so the usual choice is a ductless (mini-split) system with wall-mounted indoor units, sized room by room.
Check these three things before you switch
The Homeowner's Guide to Heat Pumps recommends starting with an EnerGuide home evaluation by a qualified Energy Advisor, then assessing sizing, electrical capacity and ductwork. In practice:
- Sizing. Your contractor should calculate your home's heat loss and heat gain, not guess from square footage or the size of your old furnace. Oversized units cycle too often and can raise energy costs, while undersized ones or poor ducts reduce comfort.
- Electrical capacity. Some homes need an electrical service upgrade to support a heat pump. Older houses with 60-amp or 100-amp service are the ones to flag early. Have this assessed before the quote, because it can change the total.
- Ductwork. A furnace often tolerates ducts that are too small or leaky. A heat pump moves more air at lower temperatures, so the duct design needs checking. Your contractor can tell you if the ducts can be reused, modified or replaced.
Pro tip: ask every contractor to show you the heat-loss calculation behind the unit size they quote. Two quotes with different sizes and no calculation are not comparable.
What it costs to replace a furnace with a heat pump
Prices vary by region, house and equipment. One 2026 Canadian cost guide puts a cold-climate heat pump replacing a gas furnace at roughly $8,000 to $15,000 installed, before any rebates. Treat that as a planning range, not a quote.
What moves the number:
| Cost factor | Why it matters |
|---|---|
| Ducted or ductless | Ductless systems need indoor units in each zone; ducted systems reuse or modify ducts |
| Capacity and model | Larger homes and cold-climate-rated models cost more |
| Electrical upgrade | A panel or service upgrade adds to the total |
| Ductwork changes | Sealing, resizing or new runs add labour and materials |
| Backup heat | Keeping the furnace costs nothing extra; adding electric resistance elements costs more |
| Removal of old equipment | An oil tank or old furnace has to be taken out properly |
Because heat pumps also cool, compare the price against a furnace plus a new air conditioner, not against a furnace alone.
Rebates: what to check in 2026 and beyond
Rebates are the part of this project that changes fastest, so rely on official pages, not on a guide's snapshot, including ours.
The federal Oil to Heat Pump Affordability program offered grants up to $10,000 for switching from oil to an eligible heat pump, with higher amounts in participating provinces that added matching grants. Natural Resources Canada's program page now shows that applications closed on July 31, 2026, and that the program is transitioning to Environment and Climate Change Canada. If you are replacing an oil furnace, read that page for the latest status and ask about provincial and utility programs, which run on their own schedules.
The rules that have applied to these programs are a useful checklist for any rebate:
- The heat pump must appear on an eligible products list and meet technical requirements such as ENERGY STAR version 6.1 certification and minimum HSPF2 and SEER2 ratings.
- It must be installed by a licensed and trained professional. NRCan highly recommends getting proof of the contractor's licence.
- Keep your invoices, equipment model numbers and evaluation reports. Programs usually ask for them.
Two habits protect you: never start work on the assumption that a program will still be open, and confirm eligibility in writing before you sign.
How the installation works
A typical furnace-to-heat-pump swap follows these steps, as described in Carrier's installation overview:
- Assessment and quote. The contractor visits, calculates heat loss, checks ducts and the electrical panel, and proposes equipment. This is where a vetted contractor earns their fee: a clean assessment prevents change orders later.
- Site preparation. The area around the indoor and outdoor units is prepared and the old equipment is shut down.
- Removal. The old furnace (and an oil tank, if you have one) is removed.
- Installation. The indoor and outdoor units are mounted, and electrical and refrigerant lines are connected. During this, contractors should make sure airflow around the unit is unobstructed and condensate drains properly.
- Testing and commissioning. The system is tested and calibrated. For a hybrid system, the contractor sets the switch-over point that decides when your backup furnace takes over.
- Paperwork. Collect invoices, model and serial numbers and any contractor attestation a rebate program requires.
Most swaps take a day or two when no electrical or duct changes are needed, but ask your contractor for a schedule in writing.
Choosing the contractor
The installer decides whether a good heat pump performs well. Look for:
- A current trade licence for your province, with proof you can keep
- Liability insurance and workers' compensation coverage
- Heat-loss calculations, not rules of thumb
- Experience with the rebate paperwork your program requires
- A written quote that lists the model, the capacity, any electrical or duct work and the backup-heat arrangement
Our contractors are vetted for licensing, insurance and rebate compliance, so you don't have to chase those documents one by one.
Get a quote from a vetted specialist
Canada Heat Pump Rebate links every eligibility fact to Canada.ca, NRCan or manufacturers, and connects homeowners with vetted, licensed, insured HVAC contractors for rebate-ready installs. If you are ready to price your own furnace replacement, request a quote from our vetted heat pump specialists.
The connection is free for homeowners, and you can use the quote to compare sizing, electrical work and backup heat in one place.
Living with your heat pump
Plan on light but regular upkeep, per the Homeowner's Guide to Heat Pumps:
- Clean or change filters on schedule.
- Keep airflow around the units unobstructed.
- Book annual contractor service.
- Keep the outdoor unit clear of debris and snow.
If you chose a hybrid system, ask your contractor to explain the switch-over temperature and how to adjust it as fuel and electricity prices change. In very cold regions, cold-climate heat pumps may need backup resistance heat or a fossil-fuel option at certain times of year, so expect that on the coldest days your backup may run.
Your 60-second cheat sheet
- Oil or electric heat now: the strongest case for going all the way to a heat pump.
- Gas heat now: compare gas and electricity rates in your province; hybrid is a strong option in colder regions.
- Before any quote: heat-loss calculation, panel check, duct check.
- Before any contract: confirm in writing which rebate programs are open and what they require.
- After install: filters, clear airflow, annual service.
FAQ
Do I need to keep my furnace if I get a heat pump?
Not always. In milder regions a cold-climate heat pump can heat the whole home. In colder or inland areas, keeping the furnace as a backup in a hybrid system can be the better design. Your contractor's heat-loss calculation and your electricity and fuel prices decide it.
Can I replace an oil furnace with a heat pump?
Yes. Oil is the fuel where switching has shown the largest savings, with NRCan reporting an average of $1,377 a year for participating households as of February 2026. Check the official program page for what is open, since intake for the federal program closed on July 31, 2026.
Can a heat pump replace baseboard heaters?
Yes. Because baseboards have no ducts, the usual option is a ductless system with wall units in the main living areas. Sizing room by room matters, so have a contractor calculate the load before you choose.
Is a heat pump cheaper to run than a furnace?
It depends on the fuel you replace, your electricity rate and your climate. Savings are typically largest when replacing oil or electric resistance heat. For gas, compare your local rates before deciding between all-electric and hybrid.
