The local context
Three commercial realities on the South Shore
Taschereau, Vieux-Longueuil and the industrial parks don’t raise the same ventilation questions. Three corridors, three ways to design the installation.
The Taschereau corridor
Boulevard Taschereau and the area around Place Longueuil form the South Shore’s main commercial corridor. Stores, car dealerships and restaurants open long hours: rooftop unit replacement is frequent, often on occupied buildings where the work has to be fast and clean.
Vieux-Longueuil and Rue Saint-Charles
The restaurants, cafés and offices on Rue Saint-Charles and in Vieux-Longueuil occupy old, mixed buildings. Limited roof space, structural constraints and kitchen ventilation to connect: design matters more here than elsewhere.
Longueuil’s industrial parks
Chemin du Coteau, Rue Rolland, Boulevard Marie-Victorin: distribution, light manufacturing and logistics, with the Saint-Hubert aerospace corridor nearby. Large volumes to handle and work to schedule around production shifts.

FAQ
Frequently asked questions
What Longueuil businesses ask us
Can you replace rooftop units on the older buildings in Vieux-Longueuil?
Yes, regularly. These buildings usually offer good roof access despite their age, and a curb adapter lets us fit a differently sized unit.
Do you install kitchen ventilation for restaurants on Rue Saint-Charles?
Yes. Hoods, ventilation and make-up air are designed to code, and we prefer to get involved early in the fit-out so the ducting is placed well.
Do you serve Longueuil’s industrial parks?
Yes: Chemin du Coteau, Rue Rolland, Boulevard Marie-Victorin and neighbouring sectors. These buildings often call for large rooftop units and process ventilation.
How do you work in a factory or warehouse that stays in operation?
By coordinating with facility management: work outside operating hours and a phased approach that keeps production areas working.
Do you work on institutional and healthcare buildings in Longueuil?
Yes, for professional, institutional and routine healthcare buildings. Large hospital complexes rely on specialised systems beyond commercial installation.
What’s the typical lead time for a rooftop unit replacement?
A simple replacement is completed in one to two days once the equipment arrives. Supply is two to four weeks for standard units.
