Duct inspection


Biovac System Inc has an experienced team trained to provide maintenance services for your HVAC (heating-ventilation-air-conditioning) systems. We follow the highest standards in the industry and use state-of-the-art equipment manufactured by us.

We are certified by the National Air Duct Cleaners Association (NADCA) for the inspection of ventilation ducts (CVI:Certified Ventilation Inspector), and for the ASCS certification (Air System Certified Specialist).

Maintenance of HVAC systems begins with an inspection. Technicians will evaluate cleanliness (dust levels) of your HVAC systems even if accessibility is difficult. If necessary, access doors will be installed to facilitate inspection by: Borescope, Wolverine Robot, Robot Desert Storm, Duct-Eye (Bull-Eye).

Inspections are documented in a clear and accurate report and accompanied by a video (optional) if need be. Recommendations will be issued as needed.

Proper maintenance of HVAC systems is a key step in the process of improving indoor air quality. By neglecting this step, accumulated contaminants are circulated back into the ambient air, thereby contributing to indoor air pollution.

The primary purpose of HVAC system air duct cleaning is to remove contaminants (dust, debris, mold and other) so that air can circulate on clean surfaces, thereby restoring efficiency and effectiveness.

We have NADCA’s Ventilation System Mold Remediator (VSMR) certification to decontaminate your contaminated HVAC systems.

We use the principle of suction, friction, and pulsation in our cleaning process.

The two methods we use for our cleaning projects are:

Traditional method: In general, this method is used for our residential projects. It is an effective and proven method. During the cleaning process, we use compressors, hoses, nozzles, whips and our dust collectors (ELITE3, ELITE5). Cleaning also includes disinfection using safe products.

Specialized method: This method is used for our commercial, institutional and industrial projects. It involves the use of robots (Wolverine, Desert Storm) in conjunction with compressor, hoses, nozzles, whips and our dust collectors (ELITE3, ELITE5). Our zoning balloons (manufacturers by ourselves) are utilized in order to isolate cleaning zones. Our robots are invaluable when it comes to accessing hard-to-reach spaces. Robots can anticipate and avoid obstacles as needed. Electrical tools and pneumatic tools each have their respective source of power: electricity and compressed air. Both contain rotating brushes to remove debris from duct surfaces. Dust is then routed to a negative-air dust collector where it is trapped. Spraying devices are used to vaporize disinfectants and coatings. Airless sprayers are also frequently used for this task. Solutions can be sprayed by a technician from a service point, sprayer installed on cart, or sprayer installed on a robot.
