A discreet and efficient HVAC installation in a red brick Montreal plex
At AirGreen , we specialize in installing HVAC systems adapted to the architectural reality of Montreal plexes . In this project located in Villeray–Saint-Michel–Parc-Extension , our team installed a Lennox wall-mounted heat pump , an ideal choice for providing comfort and energy savings in a typically urban home.
The advantages of the Lennox wall-mounted heat pump
Lennox wall-mounted heat pumps are renowned for their reliability and consistent energy efficiency, even in harsh climates like Montreal's. Their strengths include:
-
High energy efficiency , Energy Star certified.
-
Heating performance down to -25°C, reducing reliance on electric baseboards.
-
Compact design of the outdoor unit, convenient for tight spaces.
-
Quiet operation , ideal for dense areas where neighbors are close.
The particularities of the installation
The installation presented several challenges that our team was able to address with precision:
-
High wall mounting
-
The outdoor unit was fixed to sturdy brackets , anchored securely into the brick facade.
-
This configuration frees up floor space, while protecting the condenser from snow and debris.
-
-
Restricted access and security
-
As the building has a spiral metal staircase and a wooden balcony, we carefully secured the area to protect the occupants and facilitate access for technicians.
-
The use of specialized equipment allowed efficient work despite space constraints.
-
-
Passage of refrigerant and electrical conduits
-
The conduits were concealed in discreet covered wiring on the facade, ensuring both protection from the elements and a neat finish.
-
The wiring was connected directly to the home's electrical panel, in accordance with RBQ standards.
-
-
Gravity drainage of condensates
-
Thanks to the chosen location, a gravity drainage system was installed, avoiding the use of a lifting pump.
-
This solution simplifies maintenance and extends the life of the installation.
-
Challenges and solutions provided
-
Dense urban environment : a compact and quiet installation was required, respecting cohabitation in an apartment building. The Lennox heat pump perfectly meets these requirements.
-
Winter work : despite the presence of snow on the stairs, our technicians protected the intervention area and ensured the safety of the site.
Results achieved for the client
Thanks to this installation, the owner now benefits from:
-
Four-season comfort , with air conditioning in summer and efficient heating in winter.
