A suitable solution to improve comfort in a Montreal duplex
At AirGreen , we often meet owners of duplexes and small homes in Montreal who are looking for a simple, effective, and affordable solution to manage comfort in all seasons. The recent installation of a Generallux-Manuflow wall-mounted heat pump in a duplex in the Ahuntsic-Cartierville sector perfectly illustrates this approach.
Project background
The client, an owner-occupant of a duplex, had previously had an old electric heating system combined with a few portable air conditioners that were inefficient in the summer. His main concern was the lack of energy efficiency and the difficulty in achieving consistent comfort in his main living room, which was particularly exposed to temperature fluctuations.
He wanted a compact, quiet solution that was eligible for government subsidies to reduce his energy costs.
Equipment selection: Generallux-Manuflow
The Generallux-Manuflow wall-mounted heat pump has established itself as an excellent option:
-
Modulated heating and cooling capacity (12,000 BTU suitable for a 400 sq ft open living room).
-
Performance down to -25°C , ensuring comfort even during Montreal's bitter cold.
-
Eligibility for LogisVert and Federal subsidies , thanks to its energy efficiency (SEER2 and HSPF2 Energy Star certified).
-
Compact and discreet design, ideal for integrating into the living room wall, above the windows.
Technical details of the installation
The installation took place in a single day. Our technicians paid particular attention to several key points:
-
Precise drilling of the exterior wall behind the wall unit to reduce the length of the refrigeration circuit.
-
Discreet white capping along the wall, matching the existing paint.
-
Condensates drained by gravity , avoiding the need for an additional pump.
-
Reinforced wall support for the outdoor condenser , installed at a safe height to prevent obstruction by snow.
-
Nitrogen leak test and commissioning with electronic scale to ensure compliance with the manufacturer's recommended pressures.
Challenges encountered and solutions provided
The main challenge was the limited space between the top of the window and the ceiling, leaving very little room for interior installation. Thanks to the experience of our installers, we were able to optimally position the unit, while respecting the minimum clearances required by the manufacturer.
Results obtained
As soon as it was put into service, the customer was able to observe:
-
Fast and even cooling throughout the living space.
-
Quiet operation , almost imperceptible in the evening.
-
Predictable energy savings starting next winter, compared to basic electric heating.
Complete support from AirGreen
Beyond the installation, we supported the client in:
-
Submission of grant applications to Transition Énergétique Québec and the federal program.
-
Practical advice on annual maintenance (cleaning filters, inspecting the condenser).
-
A 10-year parts and compressor warranty, providing long-term peace of mind.
