Accumulation of Subsidies: Can the LogisVert Subsidy be combined with other government assistance?
A crucial subject for owners looking to save energy in Quebec
At AirGreen , we work daily with homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore who want to upgrade their HVAC (heating, ventilation, and air conditioning) systems. One of the most common questions we receive is: “Can I combine the LogisVert grant with other financial assistance programs?” The answer isn’t as simple as a “yes” or a “no” – it depends on the type of work being done, other programs in effect, and most importantly, the specific conditions of Hydro-Québec’s LogisVert program.
In this article, we explain in detail what the official LogisVert 2025 guide says on this subject, how to avoid mistakes, and above all, how to maximize your subsidies legally.
Understanding the rules of Hydro-Québec's LogisVert program
The LogisVert – Efficient Housing program was established to encourage Quebecers to adopt energy efficiency measures. It covers a wide range of measures, including:
-
Installation of efficient or high-efficiency heat pumps
-
Roof insulation and caulking work
-
Purchasing energy-efficient appliances , such as heat pump dryers and induction ranges
-
Energy-efficient swimming pool equipment
In return, Hydro-Québec offers subsidies of up to 100% of the purchase and installation cost , within the limits set for each type of measure.
What the LogisVert program explicitly says about the accumulation of aid
In section 4.1 of the LogisVert 2025 guide , it is clearly stated:
“ If your application for financial assistance is approved, you agree not to submit any other application for financial assistance to Hydro-Québec or any other government agency for the equipment or work included in your application to the LogisVert program. ”
In short: accumulation with other government programs for the same equipment or the same work is not permitted.
Why this rule? A logic of no double subsidy
The goal of this rule is to avoid what is known as “double public funding” : receiving two separate grants for the exact same expense. Hydro-Québec wants to ensure that the financial assistance provided reflects fair, transparent, and non-duplicative support.
Concrete example of a ban on accumulation
If you install a Fujitsu KZAH R-32 high-efficiency wall-mounted heat pump in Laval and apply for the LogisVert grant, you cannot simultaneously apply for the same installation through another provincial or federal program, such as:
-
Heat Green
-
Canada Greener Homes Grant
-
Renoclimat
Are there any cases where accumulation is possible?
Yes, but only if the works are separate and the grants cover different measures within the same project.
✔️ Example of possible accumulation (real scenario at AirGreen in Longueuil):
-
A customer installs a Bosch BIVA-R 454B central heat pump with AirGreen – LogisVert subsidy applicable.
-
The same customer has their roof insulated by an insulation contractor – Rénoclimat subsidy applicable for this portion, if it was not included in the LogisVert request .
✅ In this case, the accumulation is legal because the aid concerns different measures .
What happens if you accumulate by mistake?
If you receive two grants for the same equipment or work:
-
Hydro-Québec reserves the right to claim reimbursement of any amount unduly collected.
-
Your application may be denied if the double grant is discovered during verification.
-
You may be excluded from other programs in the future.
Recommendations to avoid accumulation errors
At AirGreen , we systematically advise you to:
-
Check the conditions of each program before submitting your applications.
-
Never submit the same invoice twice to different programs.
-
Keep all proof of purchase, installation, and confirmation emails .
-
If in doubt, ask for written certification from the relevant organizations.
LogisVert Bonus: a little-known but very advantageous lever
Even if accumulation with other programs is prohibited, the LogisVert program offers a very advantageous form of “internal accumulation” , called subsidized financing .
How does it work?
-
You group at least two eligible measures in the same request (for example, heat pump + induction cooker).
-
Hydro-Québec grants you a 5% bonus on the total amount of financial assistance.
Example :
-
Grant for a Gree Extreme 18,000 BTU heat pump: $1,704
-
Grant for an induction cooker: $250
-
Total: $1,954
-
5% Bonus = $97.70 extra , or $2,051.70 total.
💡 This strategy is 100% compliant with LogisVert rules and highly recommended .
How AirGreen helps you maximize your grants
We have implemented a rigorous internal process to ensure that each of our clients:
-
Receive the maximum possible grant without risking rejection or refund.
-
Receive submission assistance on the LogisVert portal .
-
Obtains compliant invoices , containing all the elements required by Hydro-Québec (RBQ number, AHRI model, technical details, etc.).
-
Benefit from our legal and regulatory expertise on grant programs in Quebec.
Conclusion: Transparency, strategy and expertise are the keys
Yes, it is possible to benefit from multiple grants – but not for the same work. Combining grants is permitted between programs if you clearly separate the eligible measures . However, applying for two grants for the same heat pump exposes you to penalties.
With AirGreen , you're in good hands: we have in-depth knowledge of each criterion of the LogisVert program and we help you maximize your return without compromising your eligibility.
