Structured presence in Mont-Saint-Grégoire, expertise in new installations

AirGreen Air Conditioning & Heating is a family business based in Montreal . With over 15 years of experience in HVAC, we install new systems for residential , commercial , and industrial projects, while also expanding our presence on the South Shore through our showroom in Boucherville . In Mont-Saint-Grégoire , we apply this experience to installations planned to ensure consistency from the outset: • defining comfort, control, and zoning requirements • integrating site constraints (clearances, pathways, access) • preparing technical interfaces (electrical, distribution, drainage, controls) to deliver a stable, repeatable, and documented new installation.

Equipment selection based on usage and loads

The installations discussed here relate exclusively to new systems , including wall-mounted heat pumps , wall-mounted air conditioners , central heat pumps , central air conditioners , multi-zone systems , air-to-water systems , PTAC/VTAC , as well as ventilation ( air exchangers , humidity control , fresh air supply ). These configurations apply equally to houses , multi-unit dwellings , commercial spaces , and mixed-use buildings , according to a technical selection logic: • building characteristics (envelope, volumes, layout, ductwork options) • usage profiles (occupancy, schedules, priority zones, fresh air requirements) • thermal loads and operating objectives (energy efficiency, stability, peak control) to ensure proper sizing and avoid performance compromises.

Controlled execution process, lasting results

Our methodology for installing new systems is structured around five pillars: system analysis , load assessment , compatibility verification , installation coordination , and commissioning . This approach aims for reliability , scalability of solutions (particularly in multi-zone or mixed-use environments), and stable long-term performance: • validation of load parameters and usage scenarios • compatibility checks (power supply, controls, distribution, interfaces) • coordination of installation steps to minimize deviations • commissioning with functional tests, adjustments, and reference measurements to ensure consistent and predictable operation.

Compliance, traceability and local relevance of the project

Quality of execution relies on regulatory compliance , rigorous coordination, and a structured handover: commissioning procedures, documentation, and clear transfer of operating information. AirGreen supports clients in understanding applicable subsidy programs, including Hydro-Québec and certain federal programs, without presenting these subsidies as guarantees or as externally managed administration; the objective remains the intrinsic performance of the system: • component durability and stability of settings • sustained energy efficiency over time • reference documentation for operation and monitoring. In Mont-Saint-Grégoire , this disciplined approach to new installations is particularly relevant to ensure consistent performance season after season, with clear deliverables and complete traceability.
