Our expertise in environmental and air quality standards enables us to provide efficient solutions to protect your occupants’ health and safety.

Our motto: Caring for people and buildings.


The comfort of students and staff is of primary importance

Poor indoor air quality is a known cause of building deterioration. Polluted ambient air has a negative impact on students and teachers, affecting their health, comfort and performance (eye irritation, shortness of breath, headaches, fatigue, etc.).

Recent studies on human exposure to atmospheric pollutants, conducted by the United States Environmental Protection Agency, indicate that pollutant levels inside a building can be two to five times (and sometimes greater than 100 times) higher than outdoor levels.

BAULNE will handle this through its comprehensive building mechanics service!

For a few years now, you have been servicing our chillers, and we can tell you that your services exceed our expectations and that we are pleased to have you as a partner to maintain our McQuay and Trane chillers. Your refrigeration specialist’s broad expertise with the different brands of chillers is undeniably one of the strongest on the market. We hope that this partnership will continue for many years.
