For this project, our AirGreen team worked in a residential home in Chomedey, Laval . The client wanted to improve the comfort of a frequently used room – halfway between a bedroom and an office – which became stifling in the summer and difficult to heat in the winter, despite the use of a tower fan placed on the floor.
We suggested adding a Gree wall-mounted heat pump dedicated to this room, for precise and quiet comfort in all seasons.
The context: a compact, very sunny room
The photo shows a room with warm orange walls , with:
-
a full-height window on the right, fitted with a thick grey curtain;
-
a relatively low textured ceiling , typical of a condo or apartment;
-
a black tower fan on the floor, a sign that the room suffered from heat during the summer.
It's a classic setup in Chomedey: a room opening onto the outside, exposed to the sun, used for both relaxation and remote work. The main challenge was to offer:
-
a stable temperature
-
very quiet operation
-
a compact solution that doesn't clutter the space.
Equipment choice: Gree 9,000 BTU wall-mounted heat pump
After analyzing the room volume, window orientation and insulation, we recommended a Gree single-zone wall-mounted heat pump of approximately 9,000 BTU .
We remain within the new generation Gree residential wall-mounted range , designed for:
-
to offer excellent energy efficiency in both air conditioning and heating;
-
maintain stable performance during the cold weather in Laval , including during periods of high winds;
-
operate with a very low noise level , ideal for a bedroom or office;
-
offer several modes (cooling, heating, dehumidification, ventilation, night mode) accessible via remote control.
Without specifying a precise commercial name, we are talking here about a high-efficiency Gree wall system , perfectly suited to individual rooms.
Indoor installation details
Positioning in the upper corner of the room
The Gree wall-mounted heat pump was installed high on the wall, in the corner, just below the ceiling and in the immediate vicinity of the window. This choice was not arbitrary:
-
the unit remains out of the direct field of vision when sitting or lying down;
-
the blown air travels along the ceiling before gently descending, which avoids direct drafts on the person sleeping or working in the room;
-
The position close to the window allows for rapid compensation of heat gains from the sun.
Curtain and airflow management
We also took into account the curtain rod and the blackout curtain :
-
the unit is positioned high enough so that the curtain, once drawn, does not block the air outlet ;
-
Our technicians checked the angle of the blower flaps so that the air is directed towards the center of the room and not against the fabric.
Result: even when the curtain is closed in the evening, the air diffusion remains effective.
Visual discretion
The Gree heat pump's glossy white finish blends well with the ceiling and contrasts slightly with the orange wall, which:
-
makes the device a clean, modern element that does not “steal the show”;
-
completely frees up the center of the wall, leaving room to add decorations or light furniture underneath, without hindering airflow.
Outdoor installation details (summary)
On the exterior side, the installation includes the Gree compressor connected to the wall unit:
-
the outdoor unit is fixed on a stable and elevated support , to protect it from the accumulation of snow and ice;
-
The refrigeration lines are insulated and protected by a clean casing running along the facade;
-
the condensation drain is directed in such a way as to avoid any splashing of water onto the walkways or walls;
-
The power supply is drawn from a dedicated circuit breaker , in accordance with Quebec standards.
The entire process is carried out in accordance with Gree's recommendations and Hydro-Québec's requirements.
Performance and benefits for the customer
1. Four-season comfort in the room
-
In summer , the heat pump provides precise air conditioning, much more efficient than the tower fan shown in the photo. It quickly reduces the temperature, even during a heat wave, while maintaining a good level of dehumidification.
-
During the off-season , it allows for slight heating without starting the main heating system of the dwelling.
-
In winter , it provides gentle and constant warmth , particularly appreciated for starting the day of teleworking or for going to bed without being cold.
2. Quiet operation
The Gree wall-mounted range is renowned for its low noise level . In this configuration, the customer benefits from:
-
with an almost inaudible operation in night mode;
-
with a very discreet ventilation noise, compatible with sleeping, reading or video conferencing calls.
3. Energy savings
By replacing the intensive use of electric baseboard heaters with the Gree heat pump, the consumer benefits from:
-
a reduction in the electricity bill , thanks to a COP well above 1 in heating;
-
an optimization of its overall consumption, by using the heat pump primarily in the room where it spends the most time.
Over the course of a year, the difference quickly becomes significant.
4. Better air quality
The Gree heat pump also contributes to better air quality :
-
filtration of circulating dust;
-
humidity control (dehumidification mode in humid periods);
-
sensation of cooler and more constant air, especially in summer.
An AirGreen installation in Chomedey: expertise and support
At AirGreen, every project is carefully studied. In this Gree wall-mounted heat pump installation in Chomedey , we have:
-
assessed the actual surface area of the room , its orientation and its use;
-
chose an appropriate capacity (approximately 9,000 BTU) to avoid both undersizing and oversizing;
-
determined the optimal position for comfort, performance and aesthetics;
-
We took care of all the steps: site visit, quote, installation, commissioning and full explanations to the client.
Our goal: to offer a reliable, durable and pleasant system for everyday use, with a present and responsive after-sales service.
Conclusion: a room transformed thanks to the Gree wall-mounted heat pump
This project in Chomedey demonstrates how a properly sized and installed Gree wall-mounted heat pump can transform the comfort of a room:
-
controlled temperature summer and winter;
-
silent operation, ideal for sleeping and working;
-
neat aesthetics, perfectly integrated into the decor;
