Commercial Heating & Air Conditioning | Grand Montréal

Grand Montréal concentrates commercial, industrial and institutional buildings with varied thermal loads. Montréal Combustion supports operations and maintenance teams on natural gas combustion, boilers, commercial heating and cooling, ventilation and mechanical plumbing.

Why structure maintenance across a multi-site metropolitan area?

A preventive maintenance strategy with regular readings reduces unplanned shutdowns on burners, heat exchangers and hydronic loops. When assets are spread across industrial zones, logistics hubs and institutional campuses, the key is a consistent monitoring method and documented interventions.

What are the local challenges for thermal systems?

Operational continuity: reducing production disruptions caused by commissioning or combustion tuning defects.
Air quality and comfort: matching airflow, pressures and actual demand without overconsumption.
Job-site coordination: scheduling shutdowns with your internal teams and other trades.

How do you manage a multi-site fleet of rooftop units and chillers?

Across a metro-scale portfolio, commercial air conditioning is managed like a fleet: an inventory of rooftop units, chillers and heat pumps, a spring tour before the first heat wave, and readings that are comparable from one site to the next. It is the summer mirror of the boiler program — the same shutdown windows to negotiate, the same documentation, the same payoff from a consolidated history.

Frequently Asked Questions

Do you service multiple boroughs in the same week?

Yes. Crews are routed by criticality and planned shutdown windows, without compromising diagnostic quality.

Do you handle combustion systems in mixed-use buildings?

Yes. The approach involves mapping the interdependencies between boiler, ventilation and controls, then securing reliable operation.

How do you prioritize a boiler or burner breakdown?

We assess safety and operational continuity first, then isolate the root cause to deliver a lasting fix.

Can you maintain a fleet of rooftop units spread across several sites?

Yes. The rooftop units of a real-estate portfolio are handled like a fleet: inventory, a spring visit ahead of the cooling season, consistent readings and prioritization of at-risk units.
