Can I combine roof insulation with a heat pump to get a larger grant?

Maximize your LogisVert grant: Combine roof insulation and a heat pump for substantial savings

As part of Hydro-Québec's LogisVert program, it is now possible to combine several energy efficiency measures to increase the amount of financial assistance granted. At AirGreen, we support our clients in Montreal, Laval, Longueuil, North Shore and South Shore on a daily basis in optimizing their HVAC (heating, ventilation and air conditioning) projects in order to obtain the maximum available subsidies . Among the most advantageous combinations is the installation of a high-efficiency heat pump accompanied by roof insulation and caulking work .

Why is this combination strategic?

Combining roof insulation with the installation of an efficient heat pump not only reduces heat loss and maximizes energy efficiency , but above all unlocks a bonus amount thanks to the “Bonus financing for multiple measures” component of the LogisVert program.

In short: you make two major ecological gestures in your home — and Hydro-Québec rewards you with a cumulative subsidy increased by 5% .

Eligibility conditions for roof insulation and heat pumps

Roof insulation and caulking work

This measure applies only to houses (single-family, semi-detached, row houses, mobile homes or four-season cottages) where electricity is the main heating source.

Technical conditions:

• Roof insulation must achieve a thermal resistance RSI of 8.8 (R-50) .

• 100% of the roof surface must be insulated with glass wool or equivalent.

• Caulking should target all potential air leak areas , including:

  • Windows

  • Exterior doors

  • Patio doors

  • Attic access hatches

  • Range hoods

  • Bathroom fans

  • Electrical outlets

  • Homes

Grant awarded: $1,500

Installation of an ENERGY STAR certified heat pump

This measure applies to several types of housing, including houses, condos, and multiplexes. It allows for the installation of:

• From a wall-mounted heat pump (mini split)

• Or a central air-air system (central split)

Terms :

• The equipment must be new .

• It must be ENERGY STAR certified (cold climate for the highest rate).

• It must be purchased in Quebec and installed in an eligible home .

• It must be installed by a company with an RBQ license and registered with the Quebec Enterprise Registrar.

Grant awarded:

• $120 per 1,000 BTU/h at -8 °C for an ENERGY STAR cold-climate model ($50 for a standard ENERGY STAR model)

Bonus for multiple measures: a smart strategy

By combining the two measures in a single application , you are eligible for a 5% bonus on the total amount of subsidies received.

Concrete example with a client in Laval

A residential owner on Lévesque Boulevard in Laval recently benefited from our support for:

• Insulate your roof (RSI 8.8) and carry out complete caulking (cost: $3,500).

• Install a Gree Extrême 18,000 BTU wall-mounted heat pump.

Calculation under the current rules (if the model is ENERGY STAR cold-climate certified and delivers 18,000 BTU/h at -8 °C):

• $1,500 for insulation and caulking

• $2,160 for the heat pump

• 5% bonus on $3,660 = $183 more

Total: $3,843

Steps to follow to obtain the grant

1. Choose a certified contractor

At AirGreen, we hold RBQ licence 5645-9605-01 (subclasses 15.8, 15.10 and 16) for the heat pump installation; the roof insulation is handled by a licensed specialized contractor. We regularly work with models such as:

• Gree Sapphire

• Fujitsu KZAH R-32

• Bosch BIVA IDS Premium R-454b

• Sharp ZU1

• Goodman R-32

2. Complete both works within 9 months

It is crucial that all work is completed within a maximum of 9 months , from the first installation.

3. Group everything into a single request on LogisVert.ca

We help you put together a complete file , with:

• Detailed invoices including RBQ numbers and GST/QST codes

• Photos of the equipment (heat pump nameplate)

• Proof of ownership

• Technical quote with AHRI number

4. Wait for validation and payment

After processing (estimated time: 10 to 12 weeks), you will receive your grants by mail at the address provided.

Mistakes to avoid

• Splitting your requests : If you make two separate requests, you lose the 5% bonus .

• Choosing a heat pump that is not eligible : only use models on the official list .

• Providing incomplete invoices : any omission may result in refusal or delay in processing.

• Install in an unheated space : Indoor units should not be placed in an uninsulated attic.
