Quick answer
As of October 2026, a heat pump in Ontario typically costs $9,000 to $16,000 installed when it’s added to an existing gas furnace as a dual-fuel system. A full cold-climate ducted system that replaces the furnace typically costs $14,000 to $24,000. A single-zone ductless mini-split typically costs $4,000 to $7,500. These are typical market ranges for Waterloo Region before rebates, not quotes. Your price depends on your home’s heat load, ductwork, electrical panel and the equipment you choose.
To run one, a cold-climate heat pump in a typical gas-heated Waterloo Region home costs more than a high-efficiency gas furnace at current rates. It costs far less than electric baseboard, oil or propane. Both points are worked through below. You can put in your own numbers with the heat pump cost calculator.
Typical installed heat pump costs in Waterloo Region
Heat pump costs in Ontario depend mostly on which kind of system you install. These ranges are our estimates of the local market as of October 2026, drawn from published Ontario contractor price guides. They are not Falconridge prices, and your quote depends on the factors in the next section.
| System | What it is | Typical installed range (before rebates) |
|---|---|---|
| Dual-fuel add-on | Cold-climate outdoor unit and indoor coil on your existing gas furnace. The furnace takes over in the deepest cold. | $9,000 to $16,000 |
| Full cold-climate ducted | Heat pump plus a new electric air handler (or a new furnace) using your existing ducts. Replaces the furnace and AC together. | $14,000 to $24,000 |
| Ductless single-zone | One outdoor unit and one wall head. Suits an addition, a finished basement or a small bungalow. | $4,000 to $7,500 |
| Ductless multi-zone | One outdoor unit and two to five indoor heads. Suits homes without ducts, such as older homes heated by boilers or baseboards. | $9,000 to $18,000 |
| Ground-source (geothermal) | Buried loop plus an indoor unit. Rare on suburban lots. | Often $25,000 and up |
A dual-fuel system often costs only modestly more than replacing a central air conditioner. That’s because the heat pump takes the AC’s place: it cools in summer and heats in spring, fall and most of the winter.
What changes the price
Installed heat pump prices vary more than furnace prices because no two homes need quite the same system. These are the factors that move a quote the most.
Heat load and size. Most detached homes in Waterloo Region land between 2 and 4 tons. A 1950s storey-and-a-half in Kitchener’s older neighbourhoods and a 2010s two-storey in northwest Waterloo can have the same floor area and very different heat losses. Sizing should come from a room-by-room heat loss calculation (CSA F280), not a rule of thumb.
Cold-climate rating. A cold-climate model keeps more of its capacity at -15°C to -25°C. It costs more than a standard heat pump, but it’s what qualifies for rebates and what makes sense for local winters. Waterloo Region’s winter design temperature is around -19°C to -20°C.
Ductwork. Heat pumps move more air at lower supply temperatures than a furnace does. Older homes often have undersized returns or a few long, starved runs. Duct changes typically add $1,000 to $5,000 (our estimate) depending on what’s accessible.
Electrical. A dual-fuel add-on usually needs one new 240-volt circuit. A full electric system with backup heat strips can push a 100-amp panel past its limit. A panel or service upgrade is a common extra, and the electrical work needs an ESA permit.
Line set and placement. Long refrigerant runs, wall brackets, condensate routing and snow clearance all add labour. In Waterloo Region, outdoor units should sit on a stand above the snow line.
Controls. A dual-fuel system needs a thermostat or control that decides when the furnace takes over. That setting matters a lot for operating cost (see below).
Rebates that bring the price down
As of October 2026, Ontario’s Home Renovation Savings Program pays $500 per ton, up to $2,000, for a cold-climate air-source heat pump in a home heated by Enbridge natural gas. In a home heated by electricity, oil, propane or wood it pays $1,250 per ton, up to $7,500. Pre-approval and a participating contractor are required. Kitchener Utilities gas customers are currently excluded from the gas-heated path. Our Ontario heat pump rebate guide covers eligibility and the steps. Amounts are “up to” figures, so check current eligibility before you sign.
| Example | Before rebate (estimate) | Rebate (up to) | After rebate |
|---|---|---|---|
| 3-ton dual-fuel add-on, Enbridge gas-heated home | $12,000 | $1,500 | about $10,500 |
| 3-ton full ducted, baseboard home with ducts added | $22,000 | $3,750 | about $18,250 |
| 4-ton dual-fuel, Enbridge gas-heated home | $14,500 | $2,000 | about $12,500 |

Running costs: heat pump vs gas at October 2026 rates
To compare running costs fairly, you need three numbers: the all-in price of gas, the all-in price of electricity, and the seasonal efficiency of each system. Here are the assumptions we used. They’re the same ones the calculator uses.
Gas price (marginal, all-in)
- Enbridge Gas, Union South rate zone (Waterloo, Cambridge, Guelph and most townships), effective October 1, 2026: delivery is 7.4325¢/m³ for usage above 250 m³ a month, and the gas supply charge plus cost adjustment is 17.7009¢/m³. That’s 25.13¢/m³, or about 28.4¢/m³ with 13% HST. There is no federal carbon charge on residential gas bills in 2026.
- Kitchener Utilities, October 2026: delivery is 11.5871¢/m³ and supply is 15.348¢/m³. That’s 26.94¢/m³, or about 30.4¢/m³ with HST.
We left out the fixed monthly charges ($28.91/month at Enbridge, $0.85/day at Kitchener Utilities). You keep paying them as long as you have a gas meter, which most dual-fuel and gas-water-heater homes do. We also left out Enbridge’s temporary rate-adjustment instalments on fall 2026 bills.
Electricity price (marginal, all-in)
The Ontario Energy Board’s Time-of-Use prices since November 1, 2025 are 9.8¢ off-peak, 15.7¢ mid-peak and 20.3¢ on-peak per kWh. Heating load falls mostly at night and on weekends, so we weighted it at about 12.7¢. On top of that we added Enova Power’s 2026 variable delivery and regulatory charges (about 2¢/kWh including line losses), then 13% HST, then the 23.5% Ontario Electricity Rebate. That works out to about 14¢ per kWh all-in. The OEB normally resets prices every November 1, so this figure will move. GrandBridge Energy (Cambridge) and Alectra (Guelph) delivery charges differ slightly.
Efficiency
- Gas furnace: 95% AFUE, the usual minimum for new gas furnaces in Canada.
- Gas energy content: about 10.4 kWh per m³ (estimate).
- Cold-climate heat pump: a seasonal COP of about 2.5 to 3.0 in Waterloo Region (our estimate). Efficiency is higher in spring and fall and lower in deep cold.
The math for a typical home
Take a detached home that burns about 1,800 m³ of gas a year for space heating. (Enbridge’s “typical” residential customer uses 2,200 m³ a year, and some of that goes to hot water.)
- Heat delivered: 1,800 m³ × 10.4 kWh × 0.95 ≈ 17,800 kWh of heat
| System | Energy used | Unit cost | Annual heating cost |
|---|---|---|---|
| Gas furnace, Enbridge | 1,800 m³ | 28.4¢/m³ | about $510 |
| Gas furnace, Kitchener Utilities | 1,800 m³ | 30.4¢/m³ | about $550 |
| Cold-climate heat pump, COP 3.0 | 5,930 kWh | 14¢/kWh | about $830 |
| Cold-climate heat pump, COP 2.5 | 7,120 kWh | 14¢/kWh | about $1,000 |
| Electric baseboard (COP 1.0) | 17,800 kWh | 14¢/kWh | about $2,490 |
The break-even point: gas heat costs about 2.9¢ per kWh of delivered heat (28.4¢ ÷ (10.4 × 0.95)). For a heat pump to match that at 14¢/kWh, it would need a COP of about 4.9. A cold-climate unit reaches that only in mild weather. So at today’s prices, a heat pump in a gas-heated Waterloo Region home doesn’t pay for itself through lower heating bills.
Where a heat pump clearly wins: against baseboard heat it saves roughly $1,500 to $1,650 a year in the example above. Oil and propane cost more per unit of heat than gas does, so heat pumps usually come out well ahead of those too. When it announced its October 2026 rebate, the federal government estimated households switching from oil or baseboard would save about $1,400 a year.
Ultra-Low Overnight pricing
The OEB’s Ultra-Low Overnight plan charges 3.9¢/kWh from 11 p.m. to 7 a.m., but 39.1¢ on weekday afternoons and evenings from 4 to 9 p.m. A heat pump runs whenever it’s cold, so most homes can’t move enough heating into the overnight window to come out ahead. ULO tends to help most when an EV or other large load also charges overnight.
So why do people install one?
Most Waterloo Region homeowners who choose a heat pump do it for one or more of these reasons:
- The AC is due anyway. A heat pump replaces the air conditioner and adds heating, so the extra cost over a new AC is often modest.
- Dual-fuel flexibility. The furnace handles the coldest hours and the heat pump handles the rest. You can change the switch-over temperature as prices change.
- Lower emissions. Ontario’s electricity grid is far cleaner than burning gas in your basement.
- Getting off oil, propane or baseboard, where the savings are real.
- Rebates for non-gas homes, which are significantly larger than for gas-heated homes.

Getting an accurate number
A price range online can’t tell you what your house needs. An accurate heat pump quote should include:
- how the system was sized for your home and our winters, not just “same size as the old AC”
- the exact outdoor and indoor model numbers, so you can confirm they’re on NRCan’s cold-climate list
- the rated heating capacity at 8.3°C and -15°C
- any duct, electrical and condensate work spelled out
- the dual-fuel control strategy and switch-over temperature, if there’s a furnace
- who handles the rebate pre-approval paperwork
Our heat pump installation page explains how we size and quote cold-climate and dual-fuel systems in Waterloo, Kitchener, Cambridge, Guelph and the surrounding townships. If you want to spread the cost, see financing.
Gas and electricity prices in this guide were current as of October 2026. Enbridge and Kitchener Utilities can change gas rates quarterly, and the OEB normally resets electricity prices every November 1.
