What Are the New Environmental Requirements for Commercial Air Conditioning in Quebec?
With stricter environmental standards in Quebec, compliance depends in part on refrigerant selection, energy performance, and a structured maintenance approach. For your commercial air conditioning in Montreal, you should check whether your equipment still uses higher global warming potential refrigerants such as R-22 or R-410A and consider transitioning to lower-impact options such as R-32 or R-454B. The requirements also emphasize energy performance, including efficiency ratings, as well as periodic maintenance that includes leak detection to reduce emissions and support lasting compliance.
At Air Spécialiste inc., we can assess your installation, recommend adjustments, and plan maintenance or upgrades based on your needs. Contact us to schedule an inspection and receive recommendations tailored to your building.
Your Checklist to Stay Compliant
To stay compliant without disrupting your operations, start with a simple, well-documented assessment. Here are the points to confirm:
-
Equipment inventory, including the installation year, overall condition, and capacities.
-
Refrigerants in use and available options for a conversion or replacement.
-
Energy performance, including settings, control sequence, and sensor calibration.
-
Maintenance plan, including leak detection, cleaning, and an intervention log.
-
Ventilation and humidity management to maintain comfort without excessive energy use.
-
Available documentation such as plans, technical sheets, and reports to avoid surprises during the work.
Once you clarify these items, you can prioritize corrections and plan a realistic upgrade.
