Beauharnois (City) — Permits and regulations applicable to heat pumps and air conditioning units
Understanding municipal obligations before HVAC work in Beauharnois
In Beauharnois, air conditioning, heating, and heat pump (HVAC) work is governed by municipal regulations designed to ensure compliance, safety, and proper integration of installations with buildings and their surroundings. Before installing or replacing a heat pump or air conditioning unit, it is essential to understand the permit requirements, procedures , and timelines applicable within the Beauharnois territory.
The purpose of this content is to provide you with complete, clear and structured information to enable you to approach your HVAC project in full compliance, while knowing how AirGreen can support you at every stage.
Requirement to obtain a municipal permit for HVAC work
Any work involving the modification, installation, or replacement of HVAC equipment may require a permit or certificate of authorization issued by the City. This mechanism allows the municipality to verify that the planned work complies with applicable urban planning regulations, both for building use and equipment placement.
The permit constitutes the official authorization to proceed with the work. Submitting an application, even if completed and paid for, should never be interpreted as permission to begin work . Only the formal issuance of the permit or certificate authorizes the start of construction.
Time required for issuing the permit
Due to a high volume of applications, it is recommended to allow up to four weeks for permit processing. While some applications may be processed more quickly, this timeframe should be factored into your project planning, especially during periods of high demand.
In practice, the average processing time is around two weeks , but this can vary depending on the complexity of the case, the time of year and the need for analysis by a municipal inspector.
Modernizing permit applications: online submission
Since February 2025, Beauharnois has offered a fully online permit application service for certain project categories, including those involving work on existing buildings. This system allows:
-
to submit an application without traveling;
-
to upload the required documents digitally;
-
to make the payment online securely;
-
to follow the progress of the case in real time;
-
to receive the permit in digital format once approved.
This modernization aims to reduce processing times, limit administrative errors and facilitate access to municipal services for citizens.
Who can apply for a permit?
The application can be submitted:
-
either by the building owner ;
-
either by an authorized representative .
If the application is submitted by a third party, a power of attorney may be required at the time of submission. A citizen account is required to access the online application platform and also allows for tracking the application.
Required documents and information
When submitting an application, the municipality may require various documents to fully understand the nature of the HVAC project. These documents must be complete and compliant; otherwise, the review of the application may be delayed. The municipal inspector assigned to the application also reserves the right to request additional information during the review process.
It is therefore important to carefully prepare all the technical information related to the planned installation (location of the unit, general characteristics of the equipment, integration into the building, etc.) before submitting the application.
Areas and situations subject to specific standards
Certain properties located within the territory of Beauharnois are subject to additional rules that may influence the installation of HVAC equipment, particularly when the building is located:
-
on a corner lot or a transverse lot;
-
near a watercourse;
-
in a constraint zone (flood or erosion zone);
-
in an area covered by an Architectural Implementation and Integration Plan (PIIA) .
In these contexts, specific requirements may apply regarding location, visual integration, or permit conditions.
File tracking and permit receipt
Depending on the nature of the request, it may be:
-
delivered quickly online, when conditions allow;
-
or forwarded to an inspector for further analysis.
An acknowledgement of receipt is then sent, and the application status can be viewed online. Once the application is approved, the permit is sent in digital format and can be printed if needed.
