Installing a ductless split system is one of the most effective ways to improve energy efficiency and year-round comfort in your Greater Montreal home. Before you begin, it’s crucial to verify whether you need a building permit for your HVAC installation. Permit requirements vary by municipality, and securing the right approvals ensures safe, code-compliant work.
Why Permits Matter in Montreal
Permits serve as a safeguard that any heating, cooling or ventilation project meets local building codes and safety standards. In Montreal, where winters can dip well below freezing, proper authorization helps protect your property from structural damage, refrigerant leaks, and electrical hazards. Additionally, a permitted installation preserves your home’s resale value and simplifies insurance and inspection processes.
Which Authority Handles HVAC Permits?
In the Greater Montreal area, permit oversight typically falls under the city or borough building department. Suburbs and neighbouring municipalities may have their own permitting offices. To get accurate information, consult your local municipal website or contact the building department directly.
When You Must Apply for a Permit
Generally, any time you install, replace or significantly alter a ductless split unit—such as mounting indoor heads, running refrigerant lines or adding new electrical circuits—a permit is required. Unlike portable or window air conditioners, mini split systems are classified as permanent fixtures under Quebec’s construction code.
Steps to Secure Your HVAC Permit
1. Prepare Your System Details
Record the brand, capacity and model of your unit, and sketch a basic layout showing the location of indoor and outdoor components.
2. Submit the Application
Most municipalities offer online permit portals. Complete the form, attach your documentation and pay the required fee. If you work with Climate Solutions, our team can handle this paperwork for you.
3. Arrange for Inspection
Once your technician installs the equipment, schedule an inspection to verify compliance with electrical, structural and safety codes. Passing this review finalizes your permit and validates the installation.
Consequences of Skipping Permits
Opting out of the permitting process might save time initially, but it can lead to costly fines, forced removal of equipment or denial of insurance claims if issues arise. Unpermitted HVAC work also complicates future property sales and can undermine system warranties.
