Frequently Asked Questions

Commercial air duct cleaning can help enhance airflow in your ductwork by removing dirt, debris, as well as any mold or mildew growing in the system. This allows the air to flow more freely throughout, improving your HVAC system’s overall efficiency. In addition, having it cleaned regularly will prevent more severe problems from occurring in the future.

Blockage is the most common cause of poor airflow in a duct system. This can be caused by many things, such as dust, debris, or even an animal nest. If you suspect your duct system is blocked, the best thing to do is contact our experts in industrial and commercial air duct cleaning. They will be able to properly inspect the system and clear any blockages.

You should. Construction debris is a common type of contamination that is found in duct systems. This debris can come from many sources, such as:

  • Drywall installation and finishing
  • Carpentry work
  • Painting
  • Insulation installation

In a new office space in North York, it’s imperative to perform commercial air duct cleaning before occupancy to ensure good indoor air quality.

The best way to determine if the HVAC system air duct cleaning was effective is to perform a visual inspection before and after. The system should not be considered cleaned if any dust or debris can be seen during the visual inspection. While you can perform your own visual inspection using a mirror and flashlight, it’s best to leave it to our professionals. We use specialized inspection tools to get better access to system components.
