In Saint-Léonard, many homeowners are converting their basements into offices, workshops, or media rooms. These spaces, often windowless and lit by fluorescent lights, can quickly become stifling in the summer and difficult to heat in the winter. This is precisely the challenge we tackled in this project: making a small basement room comfortable year-round using a Gree wall-mounted heat pump .
Context: a finished basement that lacked comfort
Our client has a small, enclosed room in the basement, used as both an office and a workspace. It includes:
-
A suspended ceiling with fluorescent lighting;
-
White walls marked at the bottom, a sign of traffic and intensive use;
-
A dark and easy-to-maintain floor;
-
Simple and functional furniture, typical of an improvised home workspace.
The observation was clear:
-
Too hot and humid in the summer , with stagnant air;
-
Cool and uncomfortable in winter , despite basic electric heating;
-
No central air conditioning system and no windows to allow heat to escape.
The ideal solution: a Gree single-zone wall-mounted heat pump , capable of providing both heating and cooling for this basement room.
Choosing the Gree wall-mounted heat pump
For this project in Saint-Léonard, we opted for a new generation Gree 12,000 BTU wall-mounted heat pump, perfectly suited to the needs:
-
To the modest size of the room;
-
At standard basement ceiling height ;
-
For intensive use in office/workshop mode.
Why Gree for this type of application?
-
Reliability and performance : Gree is one of the world's largest manufacturers of heat pumps, with units designed to operate long and stably.
-
Energy efficiency : Variable speed compressor technology allows power to be adjusted according to actual need, reducing electricity consumption.
-
Four-season comfort : efficient air conditioning in summer and efficient heating at low temperatures, ideal for Montreal's climate.
-
Quiet operation : essential in a small room where one works or concentrates.
Wall-mounted head positioning: efficiency and aesthetics
The photo clearly illustrates the care taken in positioning the indoor unit:
-
High installation, near the ceiling , in the center of the main wall;
-
Optimal clearance under the wall head , allowing the blown air to distribute freely throughout the room;
-
Alignment with the suspended ceiling , which gives an impression of natural integration into the room.
In a basement, every centimeter counts. Therefore, we have:
-
Avoid placing the unit near a corner to prevent creating dead zones or unpleasant drafts;
-
Followed the manufacturer Gree's clearance recommendations to ensure good air circulation around the device;
-
Preserved the low walls and baseboards, already marked by use, without adding unnecessary visible cable trays inside the room.
The result: an efficient, visually discreet system that does not overload an already limited space.
Management of refrigeration connections, drainage and supply
Behind the apparent simplicity of the wall-mounted head lies significant technical work. As always at AirGreen, we paid particular attention to the invisible details:
-
Refrigerant lines : optimized route between the indoor unit and the outdoor condenser, in order to limit pressure losses and maximize the efficiency of the Gree heat pump.
-
Condensate drain : adequate slope outwards or towards a designated drainage point, to prevent water backflow or damp patches on the walls.
-
Dedicated power supply : appropriate circuit breaker, compliant wiring and adequate protection to ensure a safe installation.
Even if these elements are not visible in the photo, they make all the difference between an installation "that works" and a reliable and durable installation.
The Gree outdoor condenser: quiet and robust
Each wall-mounted heat pump comes with its own Gree outdoor condenser , which we have positioned outside the house, in an area:
-
Clearly unobstructed to allow good airflow;
-
Easy access for maintenance;
-
Placed away from bedroom windows to minimize any noise disturbance.
We use wall mounts with anti-vibration pads , which reduces vibrations transmitted to the structure and increases acoustic comfort, particularly important in residential areas like Saint-Léonard.
Benefits for the client: a basement that is finally pleasant to use
Since installing this Gree wall-mounted heat pump , the client has been enjoying a completely transformed basement space:
-
Stable and comfortable temperature , summer and winter;
-
Drier and healthier air during humid periods;
-
Significant reduction in electricity bills , compared to the exclusive use of electric baseboard heaters;
-
Possibility of working at any time , without thermal discomfort or excessive noise.
In a small, enclosed room, the difference between "tolerable" and "truly comfortable" often comes down to the quality of the HVAC system. Here, the Gree performs its role perfectly.
A typical basement project in Greater Montreal
This type of installation is becoming increasingly common in our Montreal reality:
-
Basements converted into offices for teleworking;
-
Music studios, art workshops or game rooms;
-
Rooms without windows or with little natural ventilation.
The Gree wall-mounted heat pump stands out as an ideal solution: compact, quiet, energy-efficient and powerful enough to make these spaces fully usable, even during periods of intense heat or cold.
