Installation of a Gree wall-mounted heat pump in Ville-Marie

In the heart of Ville-Marie, in a condo with a clean, minimalist style typical of downtown Montreal, we were commissioned to improve the thermal comfort of a year-round occupied residential unit. The owner wanted a quiet solution that was efficient in both heating and cooling, and above all, aesthetically discreet.

We recommended the installation of a new generation Gree wall-mounted heat pump , perfectly suited to the constraints of an urban apartment: little space available, strict regulations for outdoor equipment and a high need for energy performance.


Project context: a condo in downtown Montreal

The apartment is located in a modern building in Ville-Marie, with:

  • open rooms (open area living room / kitchen);

  • white walls and standard ceilings , which reflect light well;

  • adequate insulation , but insufficient to absorb the significant temperature variations between Montreal summer and Quebec winter.

Before our intervention, the client was facing two problems:

  1. Summer overheating : even with windows closed and curtains drawn, heat accumulated in the apartment, especially in the late afternoon.

  2. Discomfort in winter : the building's heating provided a base level of warmth, but with very little fine-tuning room by room, resulting in colder areas.

The objective was therefore clear: to offer precise temperature control all year round , while optimizing energy consumption.


Choosing a Gree wall-mounted heat pump

We proposed a Gree wall-mounted, single-zone heat pump , sized to efficiently cover the main open area of ​​the condo.

This choice can be explained by several reasons:

  • High-efficiency inverter technology : the machine automatically adapts its power to actual needs, reducing frequent starts and electricity consumption.

  • Air conditioning and heating performance : ideal for supporting air conditioning during heat waves and providing efficient supplemental heating during periods of extreme cold.

  • Quiet operation : the Gree indoor unit is designed to remain very discreet, even at night, which is essential in dense urban environments.

  • Minimalist design : smooth white facade, discreet digital display on the right side – a choice that blends perfectly with the light walls of the condo.

We are talking here about a new generation Gree wall-mounted heat pump , from the manufacturer's high-efficiency residential range, designed for the North American market and the Quebec climate.


Interior installation details

Wall-mounted head positioning

In the photo, you can see the Gree indoor unit installed very close to the ceiling , with plenty of space on a large section of wall. This positioning is not accidental:

  • It allows the device to efficiently circulate the air throughout the entire volume of the room;

  • It leaves a free space under the unit for furniture and circulation;

  • It helps to avoid direct drafts on occupants sitting in the living room or at the table.

The digital display on the right shows the set temperature (here 74°F), easily readable from a distance without being visually aggressive.

Passing the connections and finishing

One of the client's objectives was to maintain clean and minimalist walls. Therefore, we:

  • runs the refrigeration lines, communication cable and condensation drain to the rear of the unit, directly through the wall;

  • The pipes were carefully insulated to prevent performance losses and condensation;

  • sealed and retouched the surface around the hole to achieve a neat finish.

Outside, the Gree compressor is installed on a suitable support, clear of snow and positioned to comply with the condominium requirements (noise, access, clearances).


Comfort, control and energy savings

Four-season comfort

With this Gree wall-mounted heat pump, the homeowner now benefits from stable comfort all year round :

  • In summer , the machine quickly removes accumulated heat, while dehumidifying the air, making the apartment significantly more pleasant during heat waves.

  • In spring and autumn , the device provides gentle heating, ideal for avoiding complete dependence on the building's central system.

  • In winter , the heat pump provides an effective supplement, particularly useful during periods of extreme cold or when central heating struggles to keep up.

Precise control and ease of use

The remote control provided by Gree allows you to:

  • to adjust the temperature to within half a degree ;

  • to choose different operating modes (heating, air conditioning, dehumidification, ventilation, automatic mode);

  • to adjust the fan speed and the direction of the louvers to avoid direct drafts;

  • to use time-based programming , in order to optimize comfort and savings.

In this condo in Ville-Marie, we took the time to guide the client in getting to grips with the device: explaining the symbols, advanced functions and best practices for reducing consumption.

Impact on the electricity bill

Compared to a window air conditioner or high-intensity electric baseboard heaters, the Gree wall-mounted heat pump typically offers:

  • lower consumption for the same amount of comfort ;

  • a better distribution of heat and coolness ;

  • the possibility of limiting the use of central heating when it is not necessary.

Over a year, this often translates into a significant reduction in energy bills , while also improving daily comfort.


A typical AirGreen project in downtown Montreal

This construction site in Ville-Marie perfectly illustrates our way of working at AirGreen:

  1. Needs analysis : understanding the condo configuration, the client's lifestyle habits and the constraints of the condominium.

  2. Recommendation for a suitable system : a Gree wall-mounted heat pump, efficient, quiet and discreet.

  3. Professional installation : optimal positioning, clean routing of connections, compliance with electrical and refrigeration standards.

  4. Commissioning and training : complete functional tests and detailed explanation of controls.

  5. Monitoring and maintenance : advice on filter cleaning, maintenance frequency and best practices to extend the system's lifespan.

Whether you live in Ville-Marie, the Plateau, Rosemont, Villeray, Laval or the South Shore, we can offer you a Gree wall-mounted heat pump solution or another brand adapted to your situation, always with the same concern for quality and transparency.
