In Brossard, on Montreal's South Shore, a family wanted to modernize their heating and air conditioning system. Their old outdoor unit was noisy, energy-inefficient, and poorly suited to Quebec's harsh winters.
We therefore proposed the installation of a Gree central heat pump , a complete solution that provides heating and air conditioning through existing ducts, while reducing energy consumption.
The project in brief
-
Location: Brossard, South Shore of Montreal
-
System type: Central heat pump (outdoor condenser connected to a ducted system)
-
Brand: Gree
-
Model: Gree Flexx R32 central heat pump, approximately 3 tons
-
Use: Primary heating in the shoulder seasons, supplemental heating in winter, central air conditioning in summer
The main objective was to replace an old air conditioner with a modern solution capable of heating and cooling the entire house through the existing ventilation system.
Why a Gree central heat pump for this house in Brossard?
1. One system for all seasons
With a Gree central heat pump, customers benefit from:
-
Efficient heating through the same ducts as the air conditioning;
-
Uniform comfort throughout all rooms, rather than room by room;
-
Automatic switching between heating and air conditioning depending on the outside temperature.
This configuration is ideal for a typical single-family home in Brossard, where a system that is simple to use and comfortable at all times is desired.
2. Energy efficiency and long-term savings
The Gree Flexx R32 series is distinguished by:
-
An inverter compressor that modulates power according to actual needs;
-
R-32 refrigerant is more efficient and less energy-intensive than older refrigerants;
-
A stable heating capacity down to largely negative temperatures, which reduces reliance on electric furnace or baseboard heaters.
The result: better controlled electricity bills , without compromising on comfort, even in cold weather.
3. Reliability and durability
The design of this Gree condenser emphasizes durability:
-
Gold-plated finned heat exchanger (anti-corrosion treatment) visible in the photo, better protected against moisture and salt;
-
Robust bodywork, designed to withstand shocks, freezing and thawing cycles;
-
Components designed for prolonged operation in harsh climatic conditions.
For a climate like that of Greater Montreal, this robustness is essential.
Outdoor installation details: stability, clearance, and snow protection
The outdoor unit was installed along a brick wall on the side of the house, in a relatively narrow but unobstructed space. Several technical choices were made to optimize long-term performance.
1. Installation on a wall bracket above the floor
Rather than placing the unit on the ground, we have:
-
Fixed to a steel wall bracket securely anchored in the concrete foundation;
-
Raised to a sufficient height to:
-
protect it from snow accumulation ;
-
Facilitate the flow of defrost water;
-
Reduce the risk of damage caused by ice or debris.
-
We can also observe below the unit the trace of water flow from the defrosting cycles in winter, proof that the height is well calculated to prevent ice from forming directly in the bottom of the condenser.
2. Management of clearances and noise
Even in a side passage, we always respect the clearances recommended by the manufacturer:
-
Free space around the fan to ensure good air circulation ;
-
Adequate distance from walls and obstacles (such as the visible gas cylinder nearby) to ensure safety and limit sound resonance;
-
Orienting the unit in such a way as to reduce the transmission of noise to neighbors and resting areas of the house.
The axial fan, combined with Gree's inverter technology, allows for particularly quiet operation , even in the evening.
3. Routing of refrigeration lines and power supply
On the left side of the photo, you can see the routing of the refrigeration lines and communication cables , carefully guided to the indoor unit:
-
Use of suitable conduits and ducts to protect the pipes;
-
Adequate insulation of the lines to limit heat loss;
-
Electrical connection on a dedicated circuit, compliant with the Quebec Electrical Code, with a circuit breaker calibrated according to the power of the condenser.
We always ensure that each installation complies with safety standards and manufacturer's recommendations.
Integration into the existing internal system
This Gree central heat pump is connected to:
-
An air manager (or electric furnace) located inside;
-
A network of air ducts distributing heating and air conditioning to all rooms.
The installation allows:
-
To preserve the existing conduit infrastructure;
-
Adding centralized control via thermostat , often programmable or intelligent;
-
To improve overall comfort without major work in the house.
In many similar projects, we replace a simple central air conditioner with a central heat pump. This allows the client to benefit from high-efficiency heating without having to renovate the entire system.
Results for Brossard customers
After commissioning and complete performance testing, the owners were able to observe:
-
A rapid temperature increase on cool evenings;
-
Uniform air conditioning in all areas served by the ducts during the summer;
-
Quieter operation than their old outdoor unit;
-
The possibility of reducing their energy consumption , while increasing their comfort.
By choosing a Gree central heat pump installed by AirGreen, they equipped themselves with a modern, durable system adapted to the winters of the South Shore.
