An energy efficiency project in the heart of a typical Montreal brick building
In the Rosemont–La Petite-Patrie neighborhood, red brick buildings are an integral part of the urban landscape. It is in this setting that our AirGreen team installed a Gree wall-mounted heat pump , an ideal choice for condominiums and apartments seeking a balance between thermal comfort and energy performance. This project perfectly illustrates our expertise in HVAC installation in urban environments where every technical detail counts.
Why the Gree heat pump is a strategic choice
The Gree brand has established itself over the past several years as a key player in the field of residential heat pumps. With a wide range of Energy Star certified units, adapted to northern climates, these units guarantee reliable operation even during Montreal's harsh winters.
The main advantages:
-
Four-season comfort : efficient heating in winter down to -25°C, optimal air conditioning in summer.
-
Energy savings thanks to high coefficients of performance (SEER/HSPF).
-
Eligibility for Quebec and Canadian subsidies for the energy transition.
-
Compactness allowing discreet integration into the courtyards and balconies of apartment buildings.
Context of the installation in Rosemont
The project involved an apartment located on the ground floor of a typical brick building. The client wanted to replace an old air conditioner with a versatile solution that provided both cooling and heating. The Gree wall-mounted heat pump met this requirement while respecting the architectural constraints.
Technical challenges encountered
The installation had two particularities:
-
Load-bearing brick wall : requiring precise drilling for the passage of refrigerant connections and the condensation drain.
-
Condenser mounting height : we opted for a raised metal support, thus avoiding the risks associated with snow accumulation and facilitating future maintenance.
Particular care was taken with the routing of cables and pipes. These were fixed along the wall with discreet capping, perfectly integrated into the brick facade.
Key steps in the process
-
Initial assessment : inspection of the facade, location of the electrical panel, validation of safety clearances.
-
Controlled drilling in the brick with thermal and acoustic insulation around the conduits.
-
Installation of the Gree condenser on its galvanized support, at an optimal height for air circulation and protection against humidity.
-
Connection of refrigerant and electrical lines in compliance with RBQ and CSA standards.
-
Commissioning and testing : pressure check, remote control calibration, heating and air conditioning mode testing.
Results obtained
The end result provides immediate comfort and a predictable reduction in annual energy bills . The client now benefits from a quiet, efficient, and energy-efficient system, adapted to the needs of an urban apartment in Rosemont. The brick wall, although initially restrictive, now provides enhanced thermal insulation around the ducts.
AirGreen tips for this type of installation
-
Always check the BTU capacity appropriate for the size of your home. Here, a 12,000 BTU unit was a perfect fit for the space.
-
Allow sufficient clearance around the condenser to avoid recirculation of hot or cold air.
-
In dense urban areas, favor a raised and discreet installation to reduce nuisances and facilitate maintenance.
-
Schedule annual HVAC maintenance (filter cleaning, refrigerant gas check, electrical inspection).
