Heat Pump Rebates in Ontario — What's Available in 2026
The rebate landscape has changed. The Canada Greener Homes Grant closed in 2024. Here is what is currently active and how Hawana navigates it for London Ontario homeowners.
Home Renovation Savings (HRS) Program — Cold-Climate Heat Pump
The Home Renovation Savings program is the primary active heat pump rebate for Ontario homeowners in 2026. Administered by Enbridge Gas and Save on Energy. Up to $7,500 for a qualifying cold-climate air-source heat pump. No energy audit required for a heat pump-only installation. Runs through November 2026.
Oil to Heat Pump Affordability (OHPA): Homes currently heated by oil are not eligible for HRS but may qualify for the separate federal Oil to Heat Pump Affordability program, which provides up to $15,000. Hawana assesses OHPA eligibility for oil-heated homes at the estimate visit. Canada Greener Homes Grant: This program closed to new applicants in 2024 and is not available for new installations in 2026. Program amounts and eligibility are subject to change — confirm current status at homerenovationsavings.ca before planning your budget.
Heat Pump Installation Prices — London Ontario 2026
Three configurations to match different homes and heating situations. All prices are all-in installed.
Ductless Mini-Split (1 Zone)
One outdoor unit, one indoor wall-mounted air handler. Heating and cooling for one room or zone. No ductwork needed. Best for additions, older homes, or supplemental zoning. Mitsubishi, Bosch, Daikin, LG.
Ducted Whole-Home ASHP
Central cold-climate heat pump connected to existing ductwork. Replaces both furnace and AC in one system. Full whole-home heating and cooling. Best for homes with existing forced-air ductwork in good condition.
Dual-Fuel — Heat Pump + Gas Backup
Cold-climate heat pump handles cooling and shoulder-season heating. Gas furnace backup activates at the switchover temperature (typically -10 to -15°C). Best of both systems for London Ontario gas homes.
After the $7,500 HRS rebate, the effective installed cost of a qualifying ducted ASHP can be under $1,000 for eligible households replacing both furnace and AC. Call Hawana for a published-price estimate and rebate eligibility assessment before you decide: (647) 550-4220.
How a Cold-Climate Heat Pump Works in a London Ontario Winter
The physics of why a heat pump delivers more heat than the electricity it consumes — even at London Ontario's design temperature of -20°C.
Heat Pump COP at Various Outdoor Temperatures
The Core Physics
A heat pump does not generate heat — it moves heat. Refrigerant circulates between an outdoor coil and an indoor coil. At the outdoor coil, the refrigerant (which vaporises at very low temperatures) absorbs heat from outdoor air even at -20°C. The compressor then raises the refrigerant pressure and temperature dramatically. At the indoor coil, the high-temperature refrigerant releases its heat to the home's air. For every unit of electricity the compressor uses, 2 to 3.5 units of heat are delivered inside the home — because most of that heat came from outdoor air, not the electricity.
What Makes Them "Cold-Climate"
Standard heat pumps lose heating capacity rapidly below +5°C. Cold-climate heat pumps use variable-speed compressors, enhanced vapour injection (EVI) technology, and refrigerants that remain effective at much lower temperatures — enabling qualifying models to maintain meaningful heating output down to -25°C. Mitsubishi Hyper-Heat, Bosch IDS Cold Climate, Daikin Aurora, and LG Therma-V are the primary models Hawana installs in London Ontario.
Cooling in Summer
The refrigerant cycle simply reverses. The heat pump extracts heat from indoor air and rejects it outdoors — identical to a central AC. Every heat pump installation by Hawana provides full-season comfort: heating from October through April, cooling from May through September, from one outdoor unit and one indoor system.
Why Dual-Fuel Makes Sense for London Ontario Gas Homes
At -20°C, the heat pump COP approaches 1.5 to 2.0. Natural gas delivered by Enbridge at London Ontario residential rates still costs less per unit of heat than electricity at COP 1.5 to 2.0 at those conditions. So the optimal London Ontario gas home strategy is: heat pump down to the crossover temperature (typically -10 to -15°C), then switch to gas. The heat pump handles 80 to 85% of annual heating hours. The gas furnace handles the coldest days. Dual-fuel captures the efficiency advantage of the heat pump while retaining the cost advantage of gas at extreme temperatures.
Dual-Fuel Heat Pump System — How It Works & Who It's For
A dual-fuel system pairs a cold-climate heat pump with a gas furnace. The control system switches automatically based on outdoor temperature, always choosing the most efficient option.
♨️ Heat Pump Mode (Most of the Year)
- All summer cooling — identical to central AC
- All fall and spring heating (October, November, March, April)
- Mild winter heating above the switchover temperature
- Typically handles 80–85% of annual heating hours
- COP 2.0–3.5 during these periods — 2–3.5x more efficient than gas
- Lowest operating cost in shoulder seasons
🔥 Gas Furnace Mode (Coldest Days)
- Activates automatically below the switchover temperature (set at -10 to -15°C)
- Handles the coldest 15–20% of London Ontario winter hours
- Full furnace capacity when heat pump efficiency advantage decreases
- Eliminates the "heat pump can't keep up in January" concern
- Can use existing gas furnace if in good condition, or new Goodman from $3,400
- Dual-fuel from $6,500 complete — both systems installed
Who dual-fuel is right for: London Ontario homes on the Enbridge natural gas grid with an existing gas furnace that is under 10 years old. The heat pump is installed alongside the existing furnace. The cost is the heat pump only — you are keeping the gas furnace. This is the lowest-cost entry point to heat pump heating for a London Ontario gas home, and the most cost-effective operating configuration given Ontario's electricity-to-gas price ratio. Cay B.'s review below describes exactly this installation at a Lambeth home.
Heat Pump vs Gas Furnace — The Right Answer Depends on Your Home
The answer is different for a London Ontario gas home vs a rural propane home vs an all-electric home. Hawana provides the comparison at every estimate visit.
| Scenario | Heat Pump Recommendation | Operating Cost vs Alternative | HRS Rebate |
|---|---|---|---|
| London Ontario natural gas home | Dual-fuel (HP + gas backup) | Lower in shoulder seasons; gas cheaper at extreme cold | Up to $7,500 |
| Rural propane home (Strathroy, Aylmer area) | Full heat pump — strong case | Significantly lower — electricity cheaper than propane | Check OHPA program |
| All-electric home (baseboard heat) | Full heat pump — strongest case | Dramatically lower — heat pump at COP 2–3 vs resistance | Up to $7,500 |
| Oil-heated home | Full heat pump — strong case | Typically lower — electricity competitive with oil | OHPA up to $15,000 |
| Addition / room without ducts | Ductless mini-split — only practical option | Lower than portable AC + electric heat | Up to $7,500 |
Honest assessment at every estimate: For most London Ontario homes on natural gas, a standalone full heat pump replacing a gas furnace has a longer payback period than the rebate marketing implies. Natural gas in Ontario is cheaper per unit of heat than electricity at the heat pump efficiency levels achievable in -20°C weather. Hawana tells you this directly, explains the dual-fuel alternative, and provides a full 10-year operating cost comparison at every heat pump estimate visit. If a gas furnace is the better financial decision for your specific home, Hawana says so — and installs the gas furnace from $3,400.

Heat Pump Reviews — London Ontario & Southwestern Ontario
138 five-star reviews — Mitsubishi ductless for Old North addition in January, Bosch IDS replaces propane near Strathroy with strong operating cost results, dual-fuel at Lambeth with honest gas-vs-heat-pump assessment. Read all ↗
"Had Hawana install a Mitsubishi Hyper-Heat ductless system in our addition at our Old North London home — a 600 sq ft room the gas furnace couldn't reach. Hawana was upfront that the main home gas furnace was right for the main structure, and the ductless heat pump for the addition. The system ran through a January at -18°C without issue. The HRS rebate application was submitted by Hawana. Honest advice on where a heat pump is and is not the right choice."
"Replaced our propane furnace and window AC units at our Strathroy home with a ducted Bosch IDS heat pump. Hawana explained why propane prices make the heat pump payback much faster than for a natural gas home. The operating cost comparison was laid out clearly. First full winter on the heat pump: heating costs significantly lower than the equivalent propane bill. Exactly what the comparison showed."
"Hawana assessed a dual-fuel setup for our Lambeth London home — on natural gas, wanted to reduce heating costs without fully committing to all-electric. The technician explained the economics clearly: heat pump handles 80–85% of heating hours; gas takes over below -12°C when electricity's efficiency advantage decreases. First year operating costs were lower than running gas alone. The HRS rebate was navigated by Hawana. No pressure to go all-electric when dual-fuel made more practical sense."
