In Rosemont–La Petite-Patrie, many families have transformed their basements into true living spaces: family rooms, TV areas, playrooms, or waiting areas for guests. This is precisely the case with this project, where our client wanted to make a large basement room more comfortable, both in summer and winter, without sacrificing aesthetics or floor space.
To meet this need, we recommended and installed a high-efficiency Gree wall-mounted heat pump , perfectly suited to the realities of Montreal's climate.
The context: a multi-purpose room to be heated and cooled
The room in question is a large rectangular room in the basement, with:
-
Suspended ceiling typical of finished basements;
-
Wall clear from top to bottom, ideal for accommodating a wall unit;
-
Light furniture (row of wooden chairs, waiting area / relaxation corner);
-
Light-colored flooring that reflects natural and artificial light well.
Before our intervention, the part suffered from two classic problems :
-
Marked coolness in winter , especially near exterior walls;
-
Stagnant heat in summer , difficult to remove without a dedicated air conditioning system.
Our objective was therefore twofold:
-
Ensuring 4-season comfort for the whole family;
-
Integrate the solution discreetly and harmoniously into an already furnished space.
The chosen solution: a high-efficiency Gree wall-mounted heat pump
We recommended the installation of a Gree wall-mounted heat pump of approximately 12,000 BTU , an ideal capacity for this type of room in the basement.
Four-season comfort for the Montreal climate
The chosen Gree wall-mounted heat pump allows for:
-
Efficient heating in winter , even during the marked cold typical of Montreal;
-
Precise air conditioning in summer , with excellent humidity control;
-
Dehumidification mode is practical in the mid-seasons, when the air becomes heavy without it being really hot.
Thanks to variable speed compressor (inverter) technology, the machine automatically adjusts its power according to the needs, which allows:
-
A stable temperature , without sudden variations;
-
Optimized energy consumption , therefore reduced electricity bills compared to electric baseboards alone.
Silence and comfort in a living room
In a room used for relaxation or entertaining guests, noise is a key factor. The installed Gree wall-mounted heat pump offers:
-
Very quiet operation in normal mode;
-
A “silent” mode that is particularly appreciated when the room serves as a TV corner or a quiet waiting room;
-
A gentle and even distribution of air throughout the room.
A neat and discreet installation
The photo clearly shows that the indoor unit is placed high up, just below the suspended ceiling , centered above a row of chairs. This positioning is not accidental.
Optimal positioning of the indoor unit
We have chosen:
-
A clear wall , without tall furniture or obstacles;
-
A generous installation height , allowing the air to mix better before descending;
-
An airflow direction oriented slightly forward , to avoid a direct draft on seated persons.
Result: the room is well air-conditioned and heated, while guaranteeing maximum comfort for the occupants .
Connection routing and condensate management
Although it's not visible in the photo, a large part of our work takes place behind the wall:
-
Refrigerant lines (insulated copper) carefully covered and routed to the outside;
-
Condensate drain installed with an adequate slope to allow gravity drainage of water produced in air conditioning mode;
-
Sealing and insulation of the wall penetration to prevent air and cold infiltration.
When gravity doesn't allow it, we can add a discreet condensate pump . In this project, the basement configuration allowed us to maintain a simple and very quiet solution.
Aesthetic integration into the room
The compact, white Gree wall unit blends perfectly into:
-
The pale grey paint on the wall;
-
The clear suspended ceiling ;
-
The warm wooden furniture retains all the character of the room.
We always ensure that our installations are as discreet as possible : no exposed cables, no visible ducts in the living area. The goal is for the heat pump to blend into the decor, without dominating it.
The advantages of a Gree wall-mounted heat pump for a house in Rosemont
Choosing a Gree wall-mounted heat pump in Rosemont–La Petite-Patrie means investing in a solution that ticks several important boxes.
Energy efficiency and savings
Compared to purely electric baseboard heating:
-
The heat pump uses 1 kWh of electricity to provide up to 3 kWh of heat (and sometimes more), depending on the conditions;
-
Energy bills decrease significantly, especially if the room was previously difficult to heat;
-
In summer, air conditioning is also more economical than a portable or window air conditioner.
Comfort in the Quebec climate
Montreal's climate, with its significant temperature variations between January and July, demands versatile systems. The Gree wall-mounted heat pump offers:
-
An extended operating range in heating;
-
Precise management of temperature and humidity ;
-
A gradual start that avoids heatstroke or chills.
For our client in Rosemont, the feeling is immediate: the room is comfortable from the morning in winter and remains cool even during heat waves.
Simple control and accessible maintenance
The machine comes with an intuitive remote control . Depending on the model, it is also possible to add a Wi-Fi module for remote control via an app.
Maintenance-related:
-
The washable filters are easily accessible by opening the front panel;
-
We recommend regular cleaning of the filters (every 4 to 8 weeks depending on usage);
-
Regular professional maintenance helps keep the heat pump performing at its best and extends its lifespan.
