Our work in Saint-Bernard-de-Lacolle exclusively involves the installation of new systems , selected and configured according to the building's specific characteristics, occupancy patterns, and performance objectives. Depending on the situation, we integrate wall-mounted heat pumps , wall-mounted air conditioners , central heat pumps , central air conditioners , multi-zone systems , air-to-water systems , and PTAC/VTAC solutions, adding complete ventilation systems (air exchangers, humidity control, fresh air supply) as needed. The choice depends primarily on the type of building— houses , multi-unit dwellings , commercial spaces , and mixed-use buildings —and on technical parameters that directly influence stability and efficiency.

• 
  thermal loads (building envelope, fenestration, infiltration, internal gains)
  
• 
  operational constraints (schedules, critical areas, occupancy density)
  
• 
  performance objectives (energy efficiency, comfort, modulation, control)
  
  This adaptation approach helps to avoid oversizing, ensures better regulation and achieves consistent performance across all seasons.

Each new installation is carried out with strict attention to regulatory compliance , quality of execution, and the coordination of critical elements to ensure stable and efficient operation over time. The project close-out phase includes commissioning procedures, the production of relevant documentation (settings, configurations, equipment information), and a structured handover of the system to clarify operation, parameters, and usage limitations. In this context, AirGreen also assists clients in understanding applicable Hydro-Québec and federal subsidy programs, without presenting these subsidies as guarantees or as automatically "taken care of" the administration: the goal is to align equipment selection with known criteria and energy efficiency principles. In Saint-Bernard-de-Lacolle, this approach is particularly relevant when projects require consistent performance despite occupancy fluctuations, zoning constraints, or tight operating objectives, as it promotes:

• 
  component durability and settings consistency
  
• 
  operational stability and controlled internal conditions
  
• 
  Measurable energy efficiency over time
  
  A new installation that is properly sized, properly integrated and properly commissioned remains the most decisive factor for stable long-term HVAC performance.
