A discreet and efficient installation by AirGreen
At AirGreen , we recently installed a Midea wall-mounted heat pump in a modern duplex in the Sainte-Dorothée district of Laval . This project perfectly illustrates our expertise in residential HVAC systems , where technical precision and architectural aesthetics go hand in hand.
The client wanted optimal thermal comfort upstairs , without compromising the building's exterior appearance. After a comprehensive energy assessment, our team recommended a Midea wall-mounted heat pump – a compact, quiet, and efficient model, ideal for multi-story residences.
Building analysis and choice of positioning
The residence, with its red brick and beige vinyl facade, presented a particular challenge: since floor space was limited, we opted for a high wall installation . This type of installation ensures both:
-
protection against snow and debris ,
-
optimal air circulation around the condenser,
-
and better durability of the system over time.
Our technicians used reinforced galvanized brackets , securely fixed into the masonry with anchors adapted to the dynamic load of the compressor. The result: a stable, discreet and secure installation.

Exemplary wiring and finishing
The electrical wiring and refrigerant pipes were routed inside a protective sheath in a color matching the facade, ensuring a harmonious visual integration .
Each connection was:
-
precisely insulated to prevent heat loss,

tested under nitrogen pressure to ensure the circuit is watertight,

hermetically sealed according to CSA and RBQ standards.
The client particularly appreciated the cleanliness of the work and the attention to detail provided by our technicians.
