City of Longueuil : Get a permit to install a heat pump or air conditioning unit

Dear Residents of the City of Longueuil,

Welcome to the page dedicated to your borough on our AirGreen website! We are here to assist you with the installation and maintenance of your HVAC equipment, meticulously adhering to the local norms and regulations in effect.

Applicable Norms in Longueuil

The equipment subject to these norms includes heat pumps, air conditioners, pumps, filters, and fans. Below are the essential points to consider:

  • Equipment Location:

    • Devices can be installed in the front, side, or back yard, as well as at the front, side, or back edges. For the boroughs of Greenfield Park and Saint-Hubert, the concept of a yard does not apply; please refer to the edges.
    • In the front yard, equipment must be concealed from street view.
  • Distances to Maintain:

    • For devices installed in a window or an opening, or on the ground in a front yard, a minimum distance of 1 meter from a property line is required.
    • For multi-family dwellings (4 units or more), devices installed on a balcony must maintain a minimum distance of 1 meter.
  • Technical Specifications:

    • Devices installed in a window or an opening do not require a permit if they are located at the basement or ground floor level of the main building, with a maximum height of 1.8 meters from the average ground level. They must also be concealed from the street by a fence, hedge, or landscaping composed of conifers.
    • Only one device per dwelling is allowed on the balcony, entirely surrounded by a railing identical to the one installed at the balcony perimeter.
    • Devices are also permitted on the flat roof of a main building.
  • Other Important Rules:

    • No device should be connected to the municipal aqueduct network.
    • The noise intensity at the property line must not exceed 53 dB(A).

It is crucial to understand that compliance with these norms and obtaining the necessary permits is the responsibility of each resident. We strongly encourage you to consult the current urban planning regulations as well as any other applicable laws or provisions.
