Permits and regulations for the installation of a heat pump or air conditioner in Lachine
Understanding local requirements before your HVAC installation
At AirGreen , we know that regulatory compliance is an essential step before any heat pump or wall-mounted air conditioner installation. In Lachine , the rules are relatively simple, but they must still be respected to avoid any future inconvenience. Here's everything you need to know before starting your heating, ventilation, and air conditioning (HVAC) work.
Rules applicable to Lachine
No permit application required
Good news: in Lachine , no municipal permit is required to install a heat pump or residential air conditioning unit .
This means you can plan your work without complex administrative procedures, while respecting local planning standards.
However, the installation must comply with current urban planning regulations . These regulations aim to ensure safety, urban aesthetics and neighborhood tranquility.
Conditions to be respected
1. Location of the device
Outdoor units should only be installed in the rear or side yards of buildings.
They must be located at a minimum distance of 2 meters from the property boundaries.
This requirement helps to limit noise and visual nuisances for neighbors and to preserve the harmony of the area.
2. Removable devices
Removable air conditioners (e.g. window or portable models) can be installed on the facade of the building.
These devices, often temporary, do not require any special authorization, but must be securely fixed and not present a risk to passers-by.
3. Installation on balcony
Appliances placed on a balcony are permitted, but must comply with the following maximum dimensions :
-
Length: 85 cm
-
Width: 40 cm
-
Height: 100 cm
These limits are intended to ensure safety, stability and to avoid excessive cluttering of outdoor spaces.
Best practices before installing
Before starting your work:
-
Contact the Lachine borough to confirm compliance with your location or any specific situation.
Telephone: 311 (or 514-872-0311 outside Montreal). -
Check noise regulations if your outdoor unit is located near a neighboring dwelling.
-
Make sure that the electrical installation is carried out by a contractor holding a valid RBQ (Régie du bâtiment du Québec) license and that any circuit modifications comply with Hydro-Québec standards.
