An AirGreen installation optimized for Montreal's climate: comfort, efficiency and sustainability combined under one roof
In the residential neighborhood of LaSalle , known for its brick buildings and covered balconies typical of southwest Montreal, our AirGreen team completed the installation of a GREE Vireo R32 wall-mounted heat pump . This project perfectly illustrates our expertise: combining energy performance , architectural discretion and protection against the extreme winter conditions of Quebec.
A smart choice for four-season comfort
The owner, wishing to reduce his dependence on traditional heating systems, chose to invest in an energy-efficient HVAC solution . His goal: to maintain consistent comfort throughout all seasons while reducing his electricity costs.
We recommended the GREE Vireo R32 wall-mounted heat pump , a modern, environmentally friendly range, specially designed for the Quebec climate .
The advantage of R32 refrigerant
GREE R32 models use a new generation refrigerant, much more environmentally friendly than R410A. This fluid allows:
-
superior energy efficiency ,
-
a reduction in the carbon footprint ,
-
and better heat transfer capacity .
This all translates into increased heating and cooling performance , even when the mercury drops below -25°C.
An installation adapted to the brick structure of LaSalle
Every building has its own unique features, and the brick walls of this duplex were no exception. Our technicians took care to:
-
fix the condenser to a corrosion-resistant galvanized wall bracket ;
-
use anti-vibration pads to ensure quiet operation;
-
protect the refrigeration ducts with a perfectly fitted white capping ;
-
make a waterproof electrical connection via a CSA-certified DuraDrive box;
-
Carefully seal the wall passage to prevent any infiltration of air or moisture.
This approach not only allows for a sustainable installation , but also a harmonious integration with the brick architecture, emblematic of the sector.
A strategic position under a covered balcony
In LaSalle, the proximity of the St. Lawrence River often results in increased humidity and heavy rainfall. To protect the heat pump from these conditions, our team installed the outdoor unit under a covered balcony .
This positioning offers several advantages:
-
protection against snow and direct rain ,
-
better longevity of external components ,
-
easy maintenance ,
-
and aesthetics preserved for the backyard.
The wall mount also allows optimal clearance for air circulation, an essential element for the performance of a heat pump.
Advanced technologies and personalized comfort
The GREE Vireo R32 is equipped with the G10 Inverter compressor , a technology that automatically adjusts the system's power according to actual needs.
Result :
-
reduced electricity consumption ,
-
ambient temperature stability ,
-
soft start that extends compressor life.
The system also offers ultra-quiet operation , ideal for urban housing in close proximity to other residences.
Technical details of the AirGreen installation
To ensure a professional-level installation, our technicians have applied AirGreen quality standards:
-
Galvanized wall bracket with heavy duty stainless steel fixings;
-
High density rubber shock absorbers to limit vibrations;
-
DuraDrive insulated conduit wiring and waterproof junction box ;
-
Refrigerant line insulated and carefully secured to prevent loss of efficiency;
-
Nitrogen pressure test to ensure the circuit is leak-proof;
-
Complete vacuuming before refrigerant charging.
Each step of the process is documented and verified to ensure safety, performance and electrical compliance .
Result: performance and serenity
As soon as it was switched on, the customer noticed an immediate improvement in interior comfort :
-
stable and uniform temperature;
-
quick control via smart remote control ;
-
significant reduction in perceived noise, both indoors and outdoors;
-
remarkable effectiveness even on cool spring evenings.
This type of installation contributes to a significant annual reduction in energy consumption , especially when it replaces a conventional electric heating system.
An installation eligible for energy subsidies
GREE R32 heat pumps are among the Energy Star models, eligible for Quebec subsidy programs such as:
-
Heat green ,
-
Renoclimat ,
-
and certain local initiatives offered by Hydro-Québec .
At AirGreen , we support each client in preparing grant documents and verifying eligibility criteria , simplifying the process from start to finish.
Expertise rooted in the Greater Montreal region
Our presence in Montreal, Laval, Longueuil, on the North Shore and the South Shore allows us to offer customized HVAC solutions according to local architectural specifications.
Brick buildings in the Southwest and LaSalle require precise installations , combining mechanical robustness and aesthetic concerns — two aspects that we master perfectly.
Each AirGreen project is carried out by certified technicians , with constant attention to detail , compliance with electrical standards and customer satisfaction .
Long-term maintenance and monitoring
To ensure long-lasting performance, we recommend:
-
cleaning the internal filters every three months ;
-
a complete annual inspection by an AirGreen technician;
-
a minimum clearance of 30 cm around the outdoor unit to ensure adequate ventilation.
Our preventative maintenance service helps extend the life of the system and prevent any drop in efficiency due to clogging or wear.
