In this Rosemont–La Petite-Patrie duplex, the owners wanted to make a courtyard-facing bedroom much more comfortable, both during heat waves and on cold Montreal winter nights. They wanted a quiet, efficient, and above all, discreet solution that wouldn't clutter the already limited space.
We recommended they install a Gree wall-mounted heat pump , a compact wall unit perfectly suited to medium-sized rooms, such as a bedroom or an office.
A targeted comfort project for the bedroom
The room to be air-conditioned overlooks the backyard, with a large window letting in plenty of light… but also summer heat. Before our intervention, the room quickly became stifling in the summer, forcing the occupants to sleep with the window open, exposed to all the noise from the neighbors.
Our mandate:
-
ensure consistent comfort in the bedroom all year round ;
-
limit noise as much as possible, especially at night;
-
preserve the clean aesthetic of the room;
-
optimize the passage of ducts to the outside without damaging the building envelope.
Choosing a Gree wall-mounted heat pump
We installed a new generation Gree wall-mounted heat pump , approximately 9,000 to 12,000 BTU, sized for the air volume of the bedroom and adjoining spaces. Gree wall-mounted heat pumps are known for:
-
their inverter technology , which modulates the compressor's power to maintain a very stable temperature;
-
their quiet operation, ideal for rest areas;
-
their ability to efficiently heat a good part of the winter, reducing reliance on electric baseboard heaters;
-
Their minimalist design makes them easy to integrate into a modern decor.
This approach allows owners to benefit from a true two-in-one system : air conditioning in the summer, efficient supplementary heating in the winter.
Installation details: ideal position and maximum discretion
The photo clearly shows the Gree wall-mounted head installed high up on a clear wall, very close to the window. This choice of location is not accidental:
-
The elevated position promotes better air circulation : the fresh or warm air then diffuses naturally throughout the room;
-
The free wall avoids any obstacle (wardrobe, bookcase, headboard) that could block the airflow;
-
The proximity of the window simplifies the passage of refrigeration lines and the condensation drain to the outside, limiting the drilling.
The refrigerant lines and drain are carefully routed to the exterior wall behind the unit, then encased externally to provide mechanical protection and a clean finish . This serves two purposes: preserving the facade's aesthetics and facilitating future access for maintenance.
Four-season comfort in Rosemont–La Petite-Patrie
In Rosemont–La Petite-Patrie, the temperature swings are well known: sweltering humidex in July, biting cold in January. The Gree wall-mounted heat pump is perfectly suited to these realities.
-
In summer , it maintains the room at the desired temperature while controlling humidity. No more overheated nights where you wake up in a sweat.
-
During the off-season , it takes over from the baseboards and allows the room to be heated at a lower cost, taking advantage of the very good energy efficiency of heat pumps.
-
In winter , it relieves the main system and offers additional comfort, particularly appreciated in the morning and evening.
Thanks to the silent mode and adjustable ventilation, occupants can sleep in a perfectly temperature-controlled room, without disturbing background noise.
Energy efficiency and savings
Installing a Gree wall-mounted heat pump in a bedroom is also an economical choice. Compared to a simple window air conditioner or a high-consumption electric baseboard heater, a heat pump:
-
consumes much less electricity for an equivalent amount of heat or coolness;
-
allows you to reduce your Hydro-Québec bill over the year;
-
increases property value, with more and more buyers looking for homes equipped with heat pumps.
During commissioning, we took the time to explain to the client how to use the different modes (heating, air conditioning, dehumidification, AUTO), how to program the night temperature and how to clean the filters in order to maintain optimal performance.
A simple and perfectly integrated result
Visually, the Gree unit blends into the white wall of the room. The simple design, with its rounded lines, harmonizes with the adjacent window and allows complete freedom in arranging the bed, furniture, and decor.
Our goal at AirGreen is always the same: to install a high-performance HVAC system without overshadowing the room . Here, the gamble has paid off: the unit is present, but unobtrusive. Its presence is most noticeable when you enjoy the coolness or warmth it provides.
