An elegant and efficient integration in the heart of a Montreal duplex
At AirGreen , we recently completed the installation of a Fujitsu Altair 300 R-32 wall-mounted heat pump in a charming duplex in Montreal's Rosemont–La Petite-Patrie neighborhood. This project perfectly illustrates how an energy-efficient HVAC solution can seamlessly integrate into a traditionally styled interior without compromising efficiency or aesthetics.
An installation adapted to the typical architecture of Rosemont
The home, with its hardwood floors and solid oak moldings , presented a classic challenge: finding the perfect location for a wall unit while preserving the character of the home.
Our technicians opted for an installation above the door frame of the central hallway , an optimal choice to maximize air circulation between the kitchen, living room and bedrooms .
Thanks to the compact shape and minimalist design of the Fujitsu Altair 300, the unit blends discreetly into the decor. Strategic positioning allows for even distribution of heat and air conditioning , without visual obstruction.
