The local context
One borough, three commercial realities
From neighbourhood streets to converted industrial buildings, it’s often the building — not the floor area — that determines the solution.
Plaza Saint-Hubert and Rue Beaubien
Two dense commercial arteries lined with mixed buildings where housing sits above the business. Varying building age means no solution copies from one unit to the next: roof access, structural capacity and duct routing are verified case by case.
Marché Jean-Talon and Boulevard Saint-Laurent
The borough’s highest concentration of food businesses: restaurants, grocery stores, butchers and fishmongers. Cooking, humidity and odours require dedicated exhaust and balanced make-up air, not just the building’s base ventilation.
Mile-Ex, Saint-Dominique and the industrial fringe
Old workshops and warehouses converted to offices, lofts and light production, out to the Viau and 46th Avenue industrial fringe. Long spans and generous heights: air distribution and process exhaust are thought through by occupied zone, not by total volume.
The system
What we install in Rosemont–La Petite-Patrie
From rooftop unit replacement on an older building to a complete restaurant kitchen exhaust system. We design and install the whole set: rooftop units (RTUs), ventilation and make-up air (MAU), commercial ductwork including NFPA 96 kitchen exhaust, and zoned treatment of technical rooms.
✓ Rooftop units (RTUs): replacement and addition
✓ Kitchen hoods, grease duct and make-up air (NFPA 96)
✓ Ventilation for restaurants and food businesses
✓ HVAC for multi-tenant buildings and ground-floor units
✓ Process ventilation for workshops and light production

FAQ
Frequently asked questions
What businesses in Rosemont–La Petite-Patrie ask us
Can you replace a rooftop unit on an older building on Rue Beaubien?
Yes, regularly. These buildings usually offer usable roof access despite their age. If the existing base won’t accept the new equipment’s dimensions, a curb adapter and duct modifications allow the installation.
Do you install restaurant hoods around Marché Jean-Talon?
Yes. We design the complete system: hood, grease duct, roof exhaust fan and a balanced make-up air unit, to the requirements that apply to commercial kitchens.
How do you work in a mixed building, with apartments above the business?
Exhaust and make-up air are sized and routed to avoid negative pressure and any backdraft toward the apartments. Access, noise and vibration are taken into account because residents share the building.
Do you serve the workshops and converted buildings of Mile-Ex?
Yes. These long-span, high-ceiling buildings are handled by occupied zone rather than total volume, with fresh-air supply matched to actual occupant density.
Do you do process ventilation in the Viau and 46th Avenue sector?
Yes, for manufacturing and warehousing: extraction of heat, vapours or dust, with the corresponding make-up air to avoid pulling the building into negative pressure.
What’s the typical lead time?
A simple rooftop unit replacement is completed in one to two days. Industrial ventilation systems or multi-unit projects run longer.
