An often underestimated yet crucial operation for the health and energy performance of commercial buildings
In the commercial sector across Montréal, Laval, Longueuil, and the surrounding areas of the North Shore and South Shore, duct cleaning for ventilation, air conditioning, and heating systems is far more than a routine maintenance measure. It’s a strategic investment that directly impacts air quality, employee well-being, energy savings, and even the longevity of HVAC equipment.
At AirGreen, we’ve helped many local businesses through customized duct cleaning services tailored to their specific needs. This article highlights real-life testimonials from professionals who experienced remarkable changes thanks to our HVAC maintenance expertise, along with essential lessons every business should know when it comes to their indoor air environment.
Why Duct Cleaning Is Critical for Businesses
Air Quality: A Public Health Issue
In a commercial setting, indoor air quality directly affects productivity, respiratory health, and occupant comfort. Ducts clogged with dust, mold, or allergens become pathways for harmful particles to spread.
Real Case: An accounting firm in downtown Montréal contacted us after several employees complained of headaches and respiratory irritation. A thermographic inspection of their ductwork revealed mold buildup behind the return air grilles. After a full cleaning and antifungal treatment, the staff noticed an immediate improvement in air quality and a significant reduction in symptoms.
Energy Performance: Tangible Savings
Dirty ducts restrict airflow, forcing HVAC units to work harder to reach the desired temperature. This leads to higher energy bills and premature wear and tear on ventilation and heating systems.
Concrete Example: A Longueuil-based SME in the food distribution industry saw an 18% spike in electricity costs over one year. Our team found a buildup of grease and dust inside the air handling ducts. After a complete cleaning, a three-month follow-up showed average monthly energy savings of 12%.
What Makes AirGreen Different
Custom Diagnosis with Robotic Visual Inspection
Before any work begins, we perform a comprehensive duct inspection using robotic cameras. This lets us assess the true condition of the ventilation network, detect obstructions or anomalies, and build a targeted, effective cleaning plan.
Professional Tools, Lasting Results
Our equipment includes high-powered industrial vacuums, rotary brushing systems, and HEPA-filtered extraction units that ensure complete removal of contaminants. We also use certified eco-friendly products that leave no chemical traces inside the ducts.
Discreet Service Without Business Disruption
We understand businesses can’t afford extended downtimes. Our technicians work daytime, evenings, or weekends based on your schedule, strictly following all health and safety protocols.
Transformation Stories: When Maintenance Changes Everything
Office Headquarters in Laval: Cleaner Air, More Efficient Team
The management of a call center based in Laval reached out after noticing an unusually high absenteeism rate. An inspection revealed ducts clogged with dust, pet hair, and pollen. The complete HVAC system cleaning was done over a weekend. The result? A 40% drop in complaints related to the work environment and normal attendance levels restored within two weeks.
Refrigerated Warehouse on the South Shore: Energy Efficiency and Enhanced Safety
In facilities where temperature control is critical, clean ventilation ducts are essential. On the South Shore, a logistics warehouse hired us to investigate a drop in air handling unit performance. The issue stemmed from the progressive clogging of thermal exchangers, reducing the flow of cool air. After cleaning, temperature stabilized and compressors now operate at 80% of their original capacity, extending their projected lifespan by 5 to 7 years.
HVAC Duct Cleaning: When, How, and How Often?
Recommended Frequency
For standard commercial environments, we recommend a full HVAC duct cleaning every 3 to 5 years. However, industries like food service, laboratories, or care centers may require more frequent cleanings.
Warning Signs It’s Time for Cleaning
-
Dust buildup around air vents
-
Unusual odors in the offices
-
Reduced heating or cooling power
-
Recurring allergy symptoms among employees
-
Unexplained increase in energy bills
