How often should commercial ducts be cleaned?

Offices: every 3-5 years. Restaurants and food service: every 1-2 years (grease loading). Industrial facilities: every 1-3 years depending on process. Post-construction: always before occupancy.

Is duct cleaning worth the cost?

For a system that has never been cleaned or has more than 5 years of buildup, yes — measurable IAQ improvement and often meaningful energy savings from restored airflow. For a young system with a good filter regime, less clear.

What is NADCA and why does it matter?

National Air Duct Cleaners Association — the industry standard for commercial duct cleaning. NADCA-compliant work uses negative-pressure vacuum, proper access, and documentation. Non-NADCA work is often just a brush pass, which is cosmetic at best.

Do you clean the AHU coils?

Yes, included in a proper commercial duct cleaning. Dirty coils cost more in energy than the cleaning costs to fix, in most cases. This is often the highest-ROI part of the service.

Can we stay in the building during the cleaning?

Yes, if we work zone-by-zone with negative pressure. For full-system cleaning we usually schedule for a weekend or extended off-hours window.

NADCA-compliant, negative-pressure

Commercial HVAC duct cleaning in Montreal

Commercial Duct Cleaning in Montreal with a locally-assigned crew. Commercial duct cleaning is not the residential $99 special. NADCA-compliant negative-pressure cleaning uses a truck-mount vacuum to pull debris out through an access panel, not just brush it around. Air quality improves measurably, energy bills often drop.

Commercial Duct Cleaning in Montreal

We’ve worked in Montreal for 12+ years. The Place Ville-Marie and McGill College Avenue business districts and the Saint-Laurent Industrial and Anjou Industrial Park industrial zones are part of our weekly route.

Commercial HVAC systems across the CMM accumulate a specific mix over years: winter salt fines that pass filters, summer pollen, general building dust, and (in older buildings) legacy construction debris. Once accumulated, the system operates at reduced efficiency and delivers reduced indoor air quality. NADCA (National Air Duct Cleaners Association) protocols exist specifically to remediate this at commercial scale.

The two things that separate real commercial duct cleaning from residential-style work are negative-pressure containment (a truck-mount vacuum creating suction while the system is cleaned so debris exits the building rather than recirculating) and access-panel installation (proper cleaning requires opening the duct at multiple points, not just at the registers). Anything less is cosmetic.

Also available in Laval, Longueuil, Brossard, Terrebonne.
