For this project, our AirGreen team was tasked with modernizing the heating and air conditioning system of a single-family home in Boucherville , on Montreal's South Shore. The homeowners wanted to replace their old, energy-inefficient system with a high-performance Gree central heat pump , capable of providing comfort and energy savings year-round.
The photo clearly shows the Gree outdoor unit installed under a wooden deck, raised on a metal stand above a bed of stones. This is a typical setup for a Gree Flexx Ultra R32 central heat pump weighing approximately 2 to 3 tons, connected to an air manager and existing ductwork inside the house.
The context: a house with ducts already in place
The Boucherville residence already had a centralized air distribution system:
-
conduits present throughout the house;
-
old, aging, noisy and less efficient outdoor unit;
-
high energy consumption in both winter and summer.
The owners wanted:
-
reduce their electricity bills ;
-
to enjoy uniform comfort in all rooms;
-
to have a reliable system to cope with Quebec's harsh winters ;
-
protect the equipment as much as possible from the elements (snow, ice, sun, driving rain).
This is exactly the type of situation where a Gree central heat pump makes perfect sense.
The system choice: Gree Flexx Ultra R32 central heat pump
We recommended the installation of a Gree Flexx Ultra R32 central heat pump , a range designed for North American homes equipped with ductwork:
-
Inverter technology : the compressor continuously modulates its speed to adapt to the actual needs of the house, which reduces on/off cycles and improves comfort.
-
R-32 refrigerant : more efficient and more environmentally friendly than R-410A, with better energy efficiency.
-
Performance in heating in cold weather : the Flexx Ultra range is designed to offer excellent performance even when the mercury drops, making it a true heating solution and not just a supplement.
-
Compatibility with existing ducts : the Gree outdoor unit integrates with an indoor air manager, allowing reuse of the ventilation network and limiting invasive work.
Thanks to this choice, the owners now have a unique system that provides both heating and air conditioning, with significantly greater efficiency than their old equipment.
Outdoor installation details: a well-considered location
Installation under the terrace
The Gree outdoor unit is installed under the wooden deck structure . This choice offers several concrete advantages:
-
Protection against snow and ice : the terrace acts as a natural roof, limiting direct accumulation.
-
Protection against driving rain and sun : the device is less exposed to extreme weather conditions, which helps to prolong its lifespan.
-
Reduction of perceived noise : the location under the terrace, combined with a bed of stones, helps to mitigate the propagation of sound towards the courtyard.
While taking advantage of this shelter, we obviously respected the required clearances around the device : the ventilated front panel remains completely clear to ensure optimal air circulation.
Raised support and drainage base
The unit is placed on a raised metal support , itself anchored to solid slabs:
-
sufficient height to keep the bottom of the unit well above the snow level;
-
mechanical stability to limit vibrations;
-
base made of slabs on a bed of stones to promote water drainage and prevent the formation of puddles and ice under the equipment.
This approach is particularly important in the Quebec context: poor support or a device placed directly on the ground can be damaged by recurring freeze/thaw cycles.
Refrigerant line and drain management
The photo also shows:
-
the protective conduit that runs along the wall to carry the refrigeration lines and cables;
-
Careful insulation of the pipes is essential to limit energy losses;
-
The condensation drain is properly directed to prevent water from accumulating near the foundation.
Everything is designed to ensure that the installation is visually clean , efficient and easy to maintain.
Winter and summer performance
Efficient heating in Quebec's climate
Thanks to Gree Flexx Ultra R32 central heat pump technology:
-
the house benefits from efficient heating even in cold weather , with a COP significantly higher than that of a conventional electric furnace;
-
the system can cover a large part, or even all, of the heating needs, resulting in a significant reduction in energy costs ;
-
The heat diffused by the ducts is homogeneous , without marked cold zones.
Comfortable central air conditioning
In summer, the Gree heat pump functions like a high-performance central air conditioner:
-
distribution of fresh air to all rooms supplied by the ducts;
-
dehumidification more effective than a simple window air conditioner;
-
increased comfort during periods of high heat, while maintaining reasonable consumption .
Concrete advantages for homeowners in Boucherville
With this Gree central heat pump installation, the homeowners now benefit from:
-
Four-season comfort throughout the house
A single technology covers both heating and air conditioning, with simple control via a central thermostat. -
Significant energy savings
By replacing an old, inefficient system, the Gree heat pump helps to lower the annual bill while reducing the carbon footprint of the residence. -
Durable and well-protected installation
The location under the terrace, the raised base, the bed of stones and the careful management of the conduits all contribute to extending the life of the equipment. -
Added value to the property
A modern central heat pump is an important asset for the resale value of the house, particularly in a market like Boucherville where buyers are looking for energy-efficient solutions.
An installation by AirGreen
At AirGreen, we don't just "replace one machine with another." For each project, we:
-
Let's analyze the reality of the house (insulation, ducts, heating and air conditioning needs);
-
let's choose the most suitable Gree heat pump model (capacity, operating range, configuration);
-
Let's plan the outdoor location to maximize both performance and durability;
-
We carry out the installation according to the strictest standards , with complete commissioning and explanations to the customer.
This Gree central heat pump installation in Boucherville illustrates our expertise: clean, thoughtful and sustainable work, serving the comfort of families in Greater Montreal.
