What happens if only part of the installation is completed?
Understanding the impacts of a partial installation under the LogisVert program
Under Hydro-Québec’s LogisVert program, the grants offered for installing energy-efficiency measures — such as ENERGY STAR certified heat pumps, roof insulation with air sealing or buying heat pump dryers — are a valuable incentive for residential owners across Québec. But one frequent and crucial question remains: what happens if the installation is only partly completed?
At AirGreen, we've helped hundreds of clients in Montreal, Laval, Longueuil, as well as on the North and South Shores apply for LogisVert grants. Drawing on our field experience, we offer a comprehensive overview of the consequences, risks, and steps to take when the installation of an eligible measure isn't completed within the prescribed timeframe.
The essential conditions of the LogisVert program
The LogisVert program provides a maximum period of 9 months from the date of implementation of the first eligible measure to complete the work and submit the grant application. This means that even if you install several pieces of equipment, the countdown begins from the first installation .
In the case of a partial installation (for example, a wall-mounted heat pump installed but the roof insulation and air sealing postponed), the application may not meet the requirements for combined funding, or may even be deemed ineligible if full proof of the work is not submitted on time.
Consequences of an incomplete installation
Loss of eligibility for the grant
If a measure included in the application is not completed or the proof of installation does not meet the criteria defined in the LogisVert guide (compliant invoice, photo, RBQ number, etc.), Hydro-Québec may reject the partial measure . This means:
-
No grant amount is paid for this measure;
-
Other measures could be reassessed individually;
-
The 5% bonus for installing multiple measures becomes ineligible.
Extension of processing times
An incomplete file systematically results in significant delays . In our experience, this can double the standard 10 to 12 week delay announced by Hydro-Québec.
Risk of repayment obligation
In the event that a subsidy is paid in error for a partial or ineligible measure, Hydro-Québec reserves the right to demand a full refund of the amount.
How to avoid problems with partial installation?
Strategic planning of works
At AirGreen, we recommend that our clients plan all eligible work within a nine-month timeframe . By submitting a single combined submission, you not only increase your chances of receiving the grant, but also the additional financing bonus offered by LogisVert.
Work with a certified and experienced installer
A significant portion of grant refusals result from incomplete or non-compliant invoices . AirGreen ensures that each invoice issued contains all required information: customer name, address, RBQ and GST/QST numbers, detailed description of the work, AHRI number in the case of heat pumps, etc.
Concrete examples from the field
Successful installation in Longueuil: Heat pump + caulking
A Longueuil client had an 18,000 BTU FUJITSU KZAH R-32 wall-mounted heat pump installed and completed the air sealing work within 7 weeks. Result: a $2,520 grant was awarded under the former heat pump and air sealing measure (withdrawn on August 25, 2025).
Partial installation in Laval: Loss of bonus
In Laval, another client installed only the heat pump and did not finish the air sealing in time. Result: only the basic heat pump grant was paid. The client also had to provide several additional documents, which pushed the payment back to more than 16 weeks.
What to do if an installation remains incomplete?
1. Do not submit the file immediately
Until all eligible measures have been completed , it is strongly recommended that you do not submit your application through the LogisVert portal. Premature submission triggers the analysis process and may freeze eligibility on an incomplete file.
2. Communicate with Hydro-Québec
If in doubt, contact LogisVert support at 1-833-396-1888 to report the situation. While they do not allow formal deadline extensions, they can guide you on best practices.
3. Contact AirGreen to finalize the work
We have a dedicated team to help you plan, carry out and quickly complete all eligible measures within the deadlines. Whether it is installing central or wall-mounted heat pumps, coordinating insulation and air sealing with a licensed contractor, or buying eligible appliances, we support you at every step.

-
