AirGreen in Saint-Mathias-sur-Richelieu

Family presence from Montreal, controlled deployment in Saint-Mathias-sur-Richelieu

AirGreen is a family-owned company based in Montreal , with over 15 years of experience in HVAC , and the ability to execute projects in residential, commercial, and light industrial environments. Our expansion on the South Shore is supported by our Boucherville showroom , which strengthens the consistency of technical choices and the coordination of stages when delivering new installations . In Saint-Mathias-sur-Richelieu , we undertake projects where the priority is a clean, sustainable, and documented installation, with understandable and traceable technical decisions.



  • Project structuring (work sequences, interfaces, integration constraints)


  • Parameter control (power supply, protections, communication, regulation)



  • Quality of execution (alignment, sealing, drainage, condensate management)

Selection of new equipment based on usage, load and building

The interventions described here involve the installation of new systems , sized and configured according to the building envelope characteristics, volumes, occupancy, and energy objectives. Depending on the type of space, we integrate wall-mounted heat pumps or air conditioners for targeted zones, central heat pumps or air conditioners for complete distribution, and multi-zone systems when several areas need to be controlled independently; some configurations also favor air-to-water systems when a hydronic approach is required. For self-contained units in light hospitality establishments, retail spaces, or offices, the PTAC/VTAC (Total Percentage Capacity/Temperature Percentage Capacity ) systems operate on a room-by-room control basis, while ventilation (air exchangers, humidity control, fresh air supply) is integrated to stabilize air quality and humidity levels. This selection applies to houses , multi-unit residential buildings , commercial spaces , and mixed-use buildings , based on:


  • Usage profile (schedules, density, critical areas, comfort requirements)



  • Thermal loads (gains, losses, internal contributions, seasonal constraints)



  • Operating objectives (efficiency, modulation, energy costs, stability)

Technical implementation process, designed to last and evolve

For each new system , our methodology relies on a clear chain of control aimed at long-term reliability and performance. It includes a system analysis (architecture, sequences, distribution), a load assessment to ensure accurate sizing, a compatibility check between equipment and accessories (interfaces, regulation, protection), phased installation coordination , and finally, commissioning to validate operating modes and parameters. This approach reduces performance variations, facilitates scalability, and stabilizes performance over the seasons.



  • Analysis (functional diagrams, integration constraints, control logic)



  • Evaluation (sizing, margins, reference conditions, balancing)


  • Compatibility (pairing units/controls, power supply, drainage, safety features)



  • Coordination (sequencing, checkpoints, intermediate tests)



  • Commissioning (testing, adjustments, validation, logging)

Compliance, documentation and sustainable performance for Saint-Mathias-sur-Richelieu

The strength of a project rests on compliant execution, rigorous coordination, and complete documentation handover at the time of transfer. Commissioning includes operational checks, adjustments to settings, and validation of safety features, followed by a structured handover with documentation , operating guidelines, and traceability elements. AirGreen also assists clients in understanding applicable Hydro-Québec and federal subsidy programs , without presenting them as guaranteed or positioning itself as an outsourced administration. In Saint-Mathias-sur-Richelieu , this approach is particularly relevant to ensuring genuine stability despite the diversity of buildings and uses, while maintaining energy efficiency over time.


  • Compliance and coordination (connections, protections, clearances, evacuations)



  • Handover file (parameters, diagrams, equipment references, proof of commissioning)



  • Operational stability (regulation, humidity, modulation, seasonal yield)

    A new installation carried out according to these standards provides a reliable, durable and consistent technical basis for projects in Saint-Mathias-sur-Richelieu.
