An HVAC installation perfectly suited to the configuration of a Montreal duplex
At AirGreen , we understand that every wall-mounted heat pump installation project requires a thorough analysis of the building, its environment, and the needs of its occupants. In Rosemont, a neighborhood where Montreal plexes often feature exterior stairs, balconies, and limited side spaces, optimizing the location of outdoor units is essential.
Our team recently installed a Gree MultiZone heat pump, consisting of two compact outdoor units mounted on wall brackets. This configuration perfectly illustrates AirGreen's expertise in residential HVAC installation in Greater Montreal.
The particularities of the project in Rosemont
Choice of location
The installation is located on the side wall of the duplex, a narrow space overlooking a fenced driveway. This layout presents several challenges:
-
limited clearance between walls and fence,
-
need to respect the ventilation distances of the units,
-
safe working height thanks to the use of a multi-section ladder.
Our technicians chose to install the Gree capacitors on galvanized steel wall brackets , fixed at an adequate height to protect them from winter snow accumulation and optimize air circulation.
Management of refrigeration connections
The connections run discreetly beneath a gray capping that matches the facade, ensuring both aesthetics and protection against the elements. Their length, adjusted to the shortest possible length, reduces energy efficiency losses and facilitates future maintenance.
Drainage and power supply
The drainage is designed using gravity, avoiding the use of a condensate pump. The electrical wiring is integrated into a vertical conduit running along the facade, directly connected to the interior panel, ensuring an installation that complies with Quebec electrical safety standards.
The advantages of a Gree MultiZone heat pump
The Gree MultiZone heat pump chosen by our customers combines performance and adaptability. Here are some highlights:
-
Versatility : possibility of connecting several independent indoor units, ideal for a Montreal duplex or triplex.
-
Energy efficiency : high coefficients of performance (SEER2 and HSPF2) ensuring significant savings on heating and cooling costs.
-
Operation in cold climates : eligible for Quebec subsidies (LogisVert, Hydro-Québec) thanks to its stable performance down to -25°C.
-
Quiet operation : optimal acoustic comfort, essential in the narrow streets of Rosemont where proximity between buildings is unavoidable.
Installation process
-
Initial analysis : inspection of the facade and planning of the conduit route.
-
Fixing the supports : reinforced anchoring of the wall brackets with mechanical sealing.
-
Installation of outdoor units : parallel installation, perfectly aligned.
-
Passage of refrigeration and electrical connections : aesthetic and safe capping.
-
Testing and commissioning : pressure control, operating tests in heating and air conditioning modes, validation of air flow and temperature.
Results for occupants
With this installation, owners now benefit from a complete system that:
-
ensures thermal comfort all year round,
-
reduces dependence on electric supplementary heating,
-
optimizes the resale value of the building,
-
improves the overall energy efficiency of the property.
