Heating with gas? Up to $9,100 to add a heat pump to your furnace
That’s dual energy. You keep the furnace, the heat pump covers about 70% of your consumption with electricity, and natural gas takes over in deep cold, below -12 °C (-15 °C in some regions). The Québec government, Hydro-Québec and Énergir together pay a good share of the work. Your amount is calculated right below.

Two questions, and you know if this page is for you
Énergir’s dual-energy program targets one specific case: a home heated with natural gas, with a central system. Start there.
Seven parts, one system. Tap the numbers.
We don’t replace your heating: we add a central heat pump to it. About 70% of your consumption moves to electricity, and the furnace only runs in deep cold.
Three choices, and you have your maximum amount
Amounts from Énergir’s Dual-energy Program participation guide, in effect April 1, 2026 (revised June 18, 2026), for an existing home. They are maximums: Énergir notes that amounts vary with the capacity of the equipment installed and the work done.
Participation guide, electricity – natural gas Dual-energy Program, in effect April 1, 2026, revised June 18, 2026. Thermostat: separate Énergir program ($100, at most 75% of the device price) and guide PE126 for the $220 supplement.
Three payers, one file
The Québec government pays the biggest share, under the 2030 Plan for a Green Economy. Hydro-Québec and Énergir add the rest. The file itself goes through Énergir.
Maximums per home
Existing buildings with 4 to 19 units. Forced air: $1,600 per unit plus $1,600, up to $32,000. Hot water: $1,000 per unit (4 to 7 units) or $1,050 (8 to 19), plus $200 per tonne of GHG avoided. These files are handled with Énergir.
Below -12 °C, a kilowatt-hour jumps from 5¢ to 30¢
With dual energy, all of the home’s electricity moves to Hydro-Québec’s Rate DT. It costs less than the usual residential rate, except in deep cold, when a kilowatt-hour costs almost six times more. That is when the furnace takes over, on its own.
Hydro-Québec rates in effect April 1, 2026, per kilowatt-hour. The threshold is -12 °C or -15 °C depending on the climate zone defined by Hydro-Québec.
Rate D or Rate DT: same electricity, two bills
Rate D (usual)
Rate DT (dual energy), above the threshold
Energy only. Rate D: 7.065¢ for the first 40 kWh of the day, 11.142¢ for the rest. Rate DT: 5.131¢ above the threshold. The network access charge is the same on both rates for one dwelling (46.154¢ per day). Gas used in deep cold and the power charge are not included. An illustration of the prices, not an estimate of your bill.
Our central heat pumps on Énergir’s list
With forced air, only a central heat pump paired with the gas furnace is eligible, and its model must be on Énergir’s list. Here are the series we install, checked one by one on September 22, 2026 against the list updated August 7, 2026.

A starting point from the heated area
Our estimators’ starting rule: about 18,000 BTU/h per 1,000 sq. ft, rounded to an available size. The final size is decided on site: ducts, furnace blower, insulation, windows, ceiling height.
The heat pump doesn’t have to do it all alone
Below the -12 °C (or -15 °C) threshold, the furnace takes over. So the heat pump works in the temperatures where it is most efficient, and what matters most becomes the right size for your ducts and furnace.
A cold-climate certified central unit still makes sense if you want to heat longer on electricity or plan ahead.
Eight conditions. Answer and we’ll tell you where you stand.
Two 12-month clocks
The participation guide says 12 months after the work starts; Énergir’s web page says 12 months after it ends. We show you the safer date.

Eight ways to lose the grant
Thermostat: $100, and $220 more under an income threshold
It is a separate Énergir program for homes with central natural gas heating. It pairs well with a dual-energy conversion: the thermostat is replaced during the work.
Gross family income and household size
2024-2025 income thresholds from Énergir’s guide PE126 (revised May 29, 2026), for owners of a house, duplex or triplex, and for landlords renting up to three units to low-income households. The supplement request is made before work starts, meaning before the first contract is signed, with proof of income.
What still exists, and what is gone
Many pages still show the old amounts. Here is where things really stand on September 22, 2026.
The dates that matter
The questions we get about dual energy
Do I keep my gas furnace?
Usually, yes: if it is in good shape, Énergir says you can keep it and simply add compatible electric equipment. Dual energy relies on both: about 70% of your consumption moves to electricity, through the heat pump, and the gas furnace takes over in deep cold. Énergir says natural gas use drops by just over 70%.
Is a wall-mounted heat pump eligible?
Not in the forced-air stream. The guide only accepts a central heat pump paired with gas equipment, whose model is on Énergir’s list.
Is the simulator amount guaranteed?
No, they are maximums. Énergir notes that the amount varies with the capacity of the equipment installed and the work, and total aid cannot exceed 80% of eligible costs: purchase, installation and start-up. Taxes, maintenance, tool rental and energy are excluded. At step 2, the contractor prepares a preliminary calculation, validated beforehand by Énergir.
Why the -12 °C threshold?
It is the threshold of Hydro-Québec’s Rate DT (-15 °C in some zones). Above it, electricity costs 5.131¢ per kWh; below it, 30.001¢. The system switches to gas on its own, through an outdoor temperature sensor.
When is the best time to convert?
Énergir says you can convert any time, but spring is ideal to add a heat pump to a forced-air system: you get air conditioning from summer on, at the dual-energy rate. If the equipment must be replaced, late summer or fall gets you ready before the cold.
Does the heat pump also cool?
Yes. A central heat pump cools the house in summer through the same ducts. And on Rate DT, air conditioning is billed at the dual-energy price, like the rest of your consumption.
I rent. Can I take part?
The dual-energy grant goes to the home’s owners. Talk to your landlord: they are the one who can apply.
Is my electrical service compatible with Rate DT?
According to Hydro-Québec, 200 A services and 400 A and up are eligible; 320 A services are not. Our estimator checks the panel during the visit.
Can I also get LogisVert?
LogisVert targets homes whose main heating is electric. If you heat with natural gas today, the program built for you is dual energy. For the other case, see our LogisVert page.
Why not go all-electric?
Énergir explains that all-electric heating puts heavy pressure on Hydro-Québec’s grid during winter peaks. Dual energy maximizes electricity while limiting that pressure, and could save Québec about $1.7 billion between 2022 and 2030 compared with an all-electric scenario.
I have a hot-water system. What is covered?
An electric boiler or an air-to-water heat pump: up to $4,100 for a house, $4,700 for a duplex and $4,800 for a triplex. If the electrical service capacity must be increased, add $2,200 ($2,400 for a duplex or triplex), and up to $5,600 if the wiring must be upgraded between the service mast and the panel.
Who pays, and when?
The Québec government (2030 Plan for a Green Economy), Hydro-Québec and Énergir. Énergir says payment comes about 30 days after confirmation, if the grant was not deducted from the invoice.
What if I sell the house?
The dual-energy contract has its own transfer rules, which Énergir explains in a leaflet. And the buyer of a home already converted cannot get aid for work done by the previous owner.
How much for the smart thermostat?
$100 for an ENERGY STAR Wi-Fi thermostat on Énergir’s list, at most 75% of its price, one per heating system. You apply in your Customer Centre within 30 days of purchase. A low-income household can get $220 more.
Does the condensing boiler grant still exist?
Not for a home: it is no longer listed among Énergir’s residential programs. The condensing combo system ($850) is still offered to builders, for new construction.
We install the central heat pump on your furnace, by the program’s rules.
At Énergir: eligibility is checked in your Customer Centre (espaceclient.energir.com). The eligible heat pump list is public: thermopompes.energir.com.
