An efficient and discreet HVAC upgrade for a LaSalle duplex
At AirGreen , we recently completed a GREE Livo R32 wall-mounted heat pump installation in a typical duplex in Montreal's LaSalle neighborhood. This project perfectly illustrates how a modern, compact solution can transform the comfort of a home while optimizing energy performance—a key issue for Montreal homeowners today.
Context of the installation: a need for four-season comfort
Our clients, living on the ground floor of a duplex, wanted to replace their old air conditioner with an energy-efficient solution capable of providing year-round heating and cooling . The limited outdoor space, combined with the proximity of a wooden staircase, required careful planning to ensure safety, efficiency, and visual privacy .
Device choice: the GREE Livo R32
The GREE Livo R32 model stood out as the ideal choice for this project:
-
Capacity : 12,000 BTU, suitable for an average sized home.
-
R-32 refrigerant : more environmentally friendly and more efficient than R-410A.
-
Winter performance : stable operation down to −25°C , perfect for Montreal's climate.
-
Energy Star certification , ensuring eligibility for subsidies from the Chauffez vert program.
This range combines reliability, low noise, and superior performance, while maintaining a discreet design that blends harmoniously with Montreal's urban facades.
Technical details of the installation
Our team carried out a complete installation by wall mounting on galvanized brackets , positioned at a safe height above ground level to avoid any winter obstruction by snow.
The key technical points:
-
Short and optimized refrigeration path , protected by discreet black capping along the wooden terrace.
-
Secure electrical connection via moisture-proof conduit.
-
Gravity drainage without condensate pump, taking advantage of the natural slope of the land.
-
Anti-vibration mount to minimize operating noise.
-
Complete leak testing of lines and pressure check before commissioning.
Coexistence with other HVAC systems
A special feature of this installation: the GREE Livo outdoor unit was positioned near an old Panasonic condenser , still in use for another dwelling in the duplex. Our technicians carefully planned the air clearances and safety distances to avoid any interference between the two systems .
This configuration demonstrates the flexibility of the Livo R32 , capable of easily integrating into tight spaces, a major asset in densely built-up areas like LaSalle.
Result: four-season comfort, without compromise
Upon starting, the occupants noted:
-
Fast and even cooling of the main parts.
-
Almost inaudible operation , even at full power.
-
A visible reduction in energy consumption compared to their old air conditioner.
Thanks to GREE inverter technology, the heat pump automatically adjusts its power according to the indoor temperature, guaranteeing constant comfort and minimal consumption .
