If you are planning an air conditioning, ventilation or heating project in Saint-Sébastien, it is essential to find out beforehand whether you need to obtain a permit.
Furthermore, it is strongly recommended to consult the regulations in force concerning the installation of heat pumps or air conditioners to ensure a compliant and trouble-free implementation!
AirGreen is a family-owned HVAC company based in Montreal, operating for over 15 years , with installation capabilities spanning residential, commercial, and industrial projects. Our expansion on the South Shore is supported by our Boucherville showroom, which facilitates site preparation, standardized methods, and resource coordination, without limiting the scope of our operations. In Saint-Sébastien, we undertake new installation projects, structuring the execution around concrete technical parameters: • layout plan and distribution logic • electrical integration and control architecture • routing, supports, and clearances for a durable installation.
The work presented here focuses exclusively on new systems , chosen to suit the building, its occupancy, and its energy objectives. We install wall-mounted heat pumps , wall-mounted air conditioners , central heat pumps , central air conditioners , multi-zone systems , air-to-water systems , PTAC/VTAC solutions, as well as ventilation systems (air exchangers, humidity control, fresh air supply). These configurations are applicable to houses , multi-unit residential buildings , commercial spaces , and mixed-use buildings , based on a rational selection process that considers: • building envelope characteristics, volumes, and distribution constraints • usage profiles and needs per zone • thermal loads and performance objectives • targeted energy efficiency and stable operating costs.
A successful new installation depends on a sequenced process that ensures compatibility and performance from the outset. Our approach includes system analysis and load assessment , followed by a compatibility check between the equipment, power supply, controls, accessories, and air or water distribution. Installation coordination relies on precise checkpoints to prevent deviations in execution: • unit placement and support management • connections (refrigerant, hydraulic, drainage) and protections • cabling, communication, and control configuration. Commissioning completes the sequence with adjustments, validations, and warm-up to ensure reliable , scalable , and stable long-term operation.
Quality of execution incorporates regulatory compliance , coordination, and traceability to support sustainability , operational stability, and energy efficiency over time. Commissioning procedures are accompanied by structured documentation and a clear system handover: • configuration parameters and control benchmarks • compliance and connection elements • operating instructions that promote actual performance. AirGreen also assists clients in understanding applicable Hydro-Québec and federal subsidy programs, without presenting them as guaranteed or as an outsourced administration. This disciplined approach is particularly relevant in Saint-Sébastien, where load variations, volumes to be served, and fresh air requirements demand consistent and verified technical integration. A properly sized new system, installed and commissioned according to a documented method, remains the foundation for stable and measurable performance.
