Local roots, structured expertise

At AirGreen , a family-owned business based in Montreal , we leverage over 15 years of experience in new HVAC installations for residential, commercial, and industrial projects, with a strong presence on the South Shore thanks to our Boucherville showroom . In Saint-Alexandre , this expertise translates into an installation approach that prioritizes the project's technical coherence from the outset, without compromising our overall capacity in other areas of our business. Our new installation work is based on concrete principles: • clear definition of comfort and operational objectives • integration of electrical, mechanical, and installation constraints from the planning stage • coordinated execution aimed at stable and repeatable performance.

Overview of equipment according to the building

The installations described here exclusively concern new systems , selected and configured to meet the realities of the building: 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 management , fresh air supply ). Whether for houses , multi-unit residential buildings , commercial spaces , or mixed-use buildings , the choice is made according to a logic of measurable performance: • building characteristics (envelope, volumes, layout) • usage profiles (occupancy, schedules, critical zones) • thermal loads and operating objectives (energy efficiency, stability, control).

Performance-oriented deployment method

For each new installation, we apply a structured methodology that prioritizes the reliability and scalability of the configurations, particularly when multiple zones or uses coexist. This approach includes analyzing the system to be implemented, assessing loads, verifying compatibility, and coordinating the installation, right up to commissioning . We proceed through controlled technical steps: • sizing and validation of load parameters • compatibility verification (electrical, refrigeration, hydraulic, controls) • installation coordination and sequencing of work • adjustments, functional testing, and documented commissioning. This rigorous approach minimizes performance variations and promotes stable long-term operation.

Sustainable compliance and documented delivery

Quality of execution relies on compliance, coordination, and traceability: we oversee commissioning procedures, documentation, and system handover to ensure sustainable and consistent operation. We also assist clients in understanding applicable subsidy programs, including Hydro-Québec and certain federal programs, without presenting them as guaranteed or as delegated administration. Deliverables are based on concrete elements: commissioning parameters, operating instructions, and reference settings; documentation of installed equipment and compliance benchmarks; and a structured handover for stable and economical use. In Saint-Alexandre , this approach is particularly relevant for ensuring the long-term durability, operational stability, and energy efficiency of new systems.
