AirGreen in the MRC de Roussillon

A structured presence for HVAC installation projects in the MRC de Roussillon

AirGreen is a family-owned business based in Montreal, with over 15 years of experience in HVAC. Our installation expertise covers residential, commercial, and industrial projects, meeting a wide range of technical and operational requirements. Our expansion on the South Shore is supported by our Boucherville showroom, allowing us to effectively assist with new installation projects in the MRC de Roussillon by ensuring a consistent approach, rational equipment selection, and controlled execution. This approach is integrated into planned projects where expected performance depends as much on system sizing as on the quality of integration. This text describes only our approach to installing new systems and does not diminish the overall scope of our activities.

Choosing the right new system according to the use, the building envelope and the thermal load

The installations described here concern new systems , selected and adapted to the specific characteristics of the building and its occupancy profile, whether it be houses , multi-unit residential buildings , commercial spaces , or mixed-use buildings . Depending on the constraints and objectives, we integrate wall-mounted heat pumps , wall-mounted air conditioners , central heat pumps , central air conditioners , multi-zone systems , air-to-water systems , as well as PTAC/VTAC and ventilation solutions (air exchangers, humidity control, fresh air supply), linking the decision to measurable parameters: • characteristics of the building envelope and the volumes to be treated • usage profiles and occupancy schedules • thermal loads and dehumidification requirements • energy efficiency and operational stability objectives. The system architecture aims for sustained performance, without oversizing, and integration compatible with the actual operation of the site.

An installation method that ensures performance and reproducibility

Our installation methodology for new systems follows a structured sequence that minimizes improvisation and stabilizes long-term results: needs and constraints analysis, load assessment, compatibility verification between equipment and components, installation coordination, and commissioning with adjustments and validations. Control points include: • consistency of sizing and required flow rates • electrical compatibility and communication between units • integration of ventilation and humidity management • parameter settings and operating sequences • performance- and stability-oriented commissioning . This approach aims for reliability , scalability of solutions (when the project requires it), and stable performance by minimizing discrepancies between design and actual operation.

Compliance, documented commissioning and local relevance in the MRC de Roussillon

Quality of execution relies on regulatory compliance, technical coordination, and rigorous project completion, where commissioning is documented and the system handover is clear. We structure: • project-specific compliance checks • commissioning procedures and parameter logging • installation documentation and operating guidelines • delivery of essential information to the client for consistent operation. AirGreen also assists clients in understanding applicable Hydro-Québec and federal government subsidy programs, without presenting these subsidies as guarantees or as delegated administration. In the MRC de Roussillon , where projects frequently combine diverse buildings, seasonal comfort needs, and energy efficiency objectives, a disciplined installation enhances sustainability , operational stability, and long-term energy performance.
