Heat pumps and air conditioners in Calixa-Lavallée

Equipment typologies and sizing logic

The work described here relates exclusively to new systems and covers, depending on the context: 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). These configurations apply to houses, multi-unit residential buildings, commercial spaces, and mixed-use buildings, based on a selection process that considers the building's characteristics and operation:

• building characteristics (envelope, volumes, layout, ductwork options)
• usage profiles (occupancy, schedules, priority zones, fresh air requirements)
• thermal loads and operational objectives (energy efficiency, stability, peak control) in order to align sizing, architecture, and settings.

Regulatory compliance, documented sustainability

Quality of execution relies on compliance, coordination, and traceability throughout the system handover process, including commissioning procedures, documentation, and a structured transfer of operating parameters. AirGreen assists clients in understanding applicable Hydro-Québec subsidy programs and certain federal programs, without presenting them as guaranteed or as outsourced administration; the priority remains the system's intrinsic performance over time. Deliverables aim for clear and stable operation: equipment documentation, compliance benchmarks, and reference parameters; operating instructions and control points related to energy stability; and a structured handover process that facilitates sustainability and energy efficiency season after season. For Calixa-Lavallée, this new installation discipline establishes a compliant, sustainable, and measurable technical framework from the outset.
