02 · Hydro-Québec funding

Hydro-Québec can pay up to 90% of your heat pump. Here are the rules.

The Efficient Solutions Program has two streams, and your rate decides which one applies. Air-source, variable refrigerant flow (VRF) and geothermal heat pumps are eligible.

04 · Equipment

Sixteen equipment families, from a simple wall mini split to a VRF system.

A small office or shop often needs just one wall heat pump; a whole building calls for ducts, a rooftop unit or VRF. The families commercial clients ask for most come first; filter by your space. Each sheet gives capacity, efficiency, refrigerant and warranty (sheet counts as of September 23, 2026). Not sure? The configurator points you in the right direction.

05 · Compliance

Two rules your equipment must follow, checked for you.

The first comes from Québec and covers any unit that contains refrigerant. The second comes from the City of Montréal and covers large buildings and new construction.

Regulation respecting halocarbons

Is your unit 20 kW or more?

Nominal capacity on the nameplate (tons)

Equivalent

Regulatory threshold20 kW (≈ 68,200 BTU/h, 5.7 t)

20 kW or more: stricter obligationsPeriodic leak check (s. 22). Leak detected: the owner notifies the Minister within 48 hours (s. 11). Work register kept for at least 5 years (ss. 59-60).

Indicative conversion (1 t = 12,000 BTU/h = 3.517 kW). Go by the nominal capacity stated by the manufacturer. Source: CQLR c. Q-2, r. 29, up to date as of May 1, 2026.

06 · Pitfalls

Six details that cost a lot when you find them too late.

BeforeThe custom path is prepared aheadIn the Medium and Large Businesses stream, the Project Proposal must be accepted before work starts.

30 daysYour invoice to Hydro-QuébecAfter the billing request, you have 30 days. Past that, Hydro-Québec can close the file.

Just 1One program per heat pumpA heat pump submitted to ÉcoPerformance is not eligible for the Medium and Large Businesses stream.

65 kWThe rate changes, so does the streamAt 65 kW of minimum billing demand, Hydro-Québec moves the customer from Rate G to Rate M or G9.

48 hA leak on a large unitOn a unit of 20 kW or more, the owner notifies the Minister within 48 hours (halocarbons, s. 11).

08 · Frequently asked questions

The questions building managers ask us.

What licences does AirGreen hold for commercial work?

RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration (air conditioning, heat pumps) and 16 Electrical. Gas, oil and hydronic work falls under other subclasses: a licensed partner takes care of it.

Which Efficient Solutions stream applies to my business?

Your Hydro-Québec rate decides. Rate G or Flex G: Small Businesses stream. Rates M, G9, L or LG: Medium and Large Businesses stream. Rate G covers a minimum billing demand under 65 kW.

Do I need Hydro-Québec’s approval before the work?

In the Small Businesses stream, the request is filed after installation. In the Medium and Large stream, the custom path requires a Project Proposal accepted before work starts; the simplified path goes through the OSE tool.

Does Hydro-Québec really pay 90%?

That is the maximum in the Small Businesses stream: you pay at least 10% of eligible costs. The actual amount is calculated measure by measure with Hydro-Québec’s OSE tool.

Is a VRF system eligible?

Yes. Hydro-Québec lists variable refrigerant flow heat pumps among the models supported by Efficient Solutions, along with air-source and geothermal heat pumps.

My rooftop unit runs on gas. Can you replace it?

We install the electric packaged heat pump that replaces it, with its electrical hookup. Disconnecting the gas supply is done by a licensed gas contractor.

My building is 2,500 m² in Montréal. What do I have to report?

By-law 21-042 covers buildings of 2,000 m² or more, or with 25 or more units. You report the previous year’s energy consumption by June 30, every year.

Who has to get the leak check done?

The owner of a unit of 20 kW or more. The check is done by a worker holding the environmental qualification attestation, and recorded in a register kept for at least 5 years.

Do you install PTACs for hotels and residences?

Yes: 100 PTAC spec sheets online (Amana, Trane, Friedrich, Gree and others) and 14 Friedrich VTAC sheets for closet units.

Where are you located?

Montréal–Laval office at 4951 Sainte-Catherine East, and South Shore showroom at 1370 rue Joliot-Curie, unit 712, in Boucherville. Monday to Thursday 8 a.m. to 6 p.m., Friday 8 a.m. to 4 p.m.
