Lennox: Rooftops and Commercial Furnaces | Montréal Combustion
Which Lennox equipment do you primarily cover?
We focus on rooftops and commercial furnaces used for heating and air conditioning in high-occupancy buildings. Our approach is pragmatic: identify the root cause (combustion, air distribution, automation), then stabilize the installation to prevent recurring shutdowns.
How do you structure on-site work?
After a structured diagnostic, we proceed with immediate repair when parts and safety allow, otherwise we propose a return-to-service plan with intervention windows compatible with your operations. Preventive maintenance can include filter tracking, belt monitoring, ignition sequence checks and flue gas / combustion air exchange verification.
What information helps speed up diagnosis before arrival?
Alarm history, actual operating loads and rooftop access constraints allow us to target priority checks and reduce downtime.
Positioning note: Montréal Combustion is an independent expert — not affiliated with Lennox and holding no manufacturer representation mandate. Our role is technical and multi-brand.
