Installation of a Gree central heat pump in Boucherville

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:

1. Four-season comfort throughout the house
   A single technology covers both heating and air conditioning, with simple control via a central thermostat.

2. 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.

3. 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.

4. 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.
