In this project in Saint-Laurent , we assisted a condo owner who wanted to efficiently heat and cool their condo while respecting the constraints of an apartment building with concrete balconies. The chosen solution: a Gree wall-mounted heat pump , installed on the private balcony, with a clean finish that met the condominium's requirements.
A typical Montreal condo environment
The building is a red brick structure with concrete balconies , typical of residential areas in Saint-Laurent. The main constraints were:
-
limited outdoor space on the balcony;
-
respecting clearances so as not to obstruct the owner's movement;
-
noise and vibration control to preserve the peace and quiet of the neighbors;
-
aesthetic integration of the equipment on the facade.
Our goal: to integrate the Gree heat pump discreetly, stably and quietly , without compromising performance.
Choosing a Gree wall-mounted heat pump
For this condo, we opted for a Gree wall-mounted heat pump from the high-efficiency residential range, ideal for:
-
air-condition the main living area (living room, dining room, open-plan kitchen) in summer ;
-
to provide economical heating during autumn, winter and spring;
-
reduce reliance on electric baseboard heaters and therefore the electricity bill.
Gree's inverter technology allows the compressor's power to be modulated according to actual demand. The result:
-
more stable temperature, without large hot/cold swings;
-
soft starts, which limits noise and prolongs the life of the device;
-
optimized consumption, particularly appreciated in a condo context where every kWh counts.
Although the precise model is not highlighted, it is a new generation Gree wall-mounted heat pump , operating with a modern, high-energy-efficiency refrigerant, perfectly suited to the climate of Greater Montreal.

Elevated support and vibration management
The metal support offers several advantages:
-
It raises the heat pump to promote water drainage and air circulation;
-
It moves the mass of the device from the ground directly to the contact points of the support, which reduces the risk of permanent marks on the slab;
-
Combined with anti-vibration pads under the unit's feet, it reduces the transmission of vibrations to the structure, thus reducing the noise felt inside and by neighbors.
This attention to detail is essential in co-ownership, where acoustic comfort is often a major issue.
Clearances and air circulation
The heat pump is positioned:
-
close to the brick wall, to reduce the footprint on the balcony;
-
with sufficient clearance in front of the fan, despite the concrete guardrail, allowing air to escape freely to the outside;
-
at a reasonable distance from the patio door, so as not to obstruct movement or the furniture on the balcony.
We always make sure to respect the clearances recommended by the manufacturer , which are essential to ensure the performance and longevity of the equipment.
Finishing of the conduits and integration into the building
The refrigerant lines and condensate drain are grouped in an insulated sleeve, covered with a white sheath that runs along the brick wall to the point of entry into the condo.
This treatment allows:
-
to protect the pipes against UV rays, rain and impacts;
-
to limit heat loss in the ducts;
-
to offer a sober and clean aesthetic , in line with the expectations of the condominium.
An electrical junction box is fixed to the wall, close to the outdoor unit, facilitating access for any maintenance or inspection and ensuring compliance with the electrical code .
Interior comfort in the condo: silence and performance
Inside, the Gree wall-mounted head unit is installed in the main living area of the condo:
-
It circulates the air gently but effectively , to cover the entire open-plan living room and kitchen;
-
Its quiet operation is particularly appreciated in a space where one works, watches television or receives guests;
-
In heating mode, it provides rapid and even heat, reducing the use of electric baseboard heaters.
For a condo occupant in Saint-Laurent, this means:
-
less temperature variation , even during heat waves;
-
a more stable feeling of comfort in winter, with less dry air than with purely electric heating;
-
better control of the Hydro-Québec bill , thanks to the superior efficiency of the heat pump.
An installation designed for the condominium
Installing a heat pump on a condo balcony often requires:
-
approval from the condominium association ;
-
compliance with an external appearance charter (maximum visible height, color of equipment, etc.);
-
taking into account acceptable noise levels for neighbors.
In this project, we have:
-
proposed a compact Gree solution , adapted to the size of the balcony;
-
carefully positioned the unit to minimize its visual impact from the street and other balconies;
-
I chose a quiet model that meets the acoustic comfort requirements in an urban environment.
Our teams are used to coordinating with condominium associations to provide plans, technical specifications and information necessary to obtain permits.
