To keep your Montreal renovation budget under control, consider the following factors:

Dimensions and configurations: System installation depends on several aspects, including the size and layout of the property, room divisions, number of storeys and ceiling height. Also, buildings in Montreal sometimes lack adequate insulation, making it essential to assess needs.
Choosing a system: The price will vary depending on whether you opt for a single unit or a central system. The energy source you choose will also influence the final bill. For example, an environmentally friendly option such as geothermal energy involves high installation costs.
Scope of work: Renovations may be necessary to add ducts, pipes, or openings in the structure. In this case, it’s important to follow the local regulations in Montreal, as well as Quebec’s building codes and standards.
