At AirGreen , we know that installing a heat pump or air conditioning unit in Montreal—and more specifically in the Côte-des-Neiges–Notre-Dame-de-Grâce (CDN–NDG) borough—requires a good understanding of municipal bylaws . While some installations are exempt from permits, it is essential to comply with urban planning standards and requirements related to safety, noise, and visual integration.

The device can be installed less than one meter from the boundaries of the land , provided that these dimensions are respected.
