Tight space, big solutions! See how AirGreen’s latest Gree heat pump installation in Sainte-Thérèse maximizes comfort and style.

Take a tour of the installation
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.

Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
A Compact Solution with Powerful Benefits
When faced with challenging spaces and specific aesthetic demands, the HVAC industry must respond with innovation and precision. At AirGreen, we recently achieved such a feat in Sainte-Thérèse, on the North Shore, where we successfully installed a Gree Free Match Extreme DoubleZone Heat Pump. This installation not only tackled the spatial constraints but also brought forth a system equipped to handle the extremes of Canadian weather, all while blending seamlessly into the home’s architecture.
The Challenge: Aesthetic and Functional Excellence
The primary challenge of this installation was the limited space available for placing the external compressor unit. Our client desired a solution that was not only efficient but discreet, prioritizing both performance and aesthetics. The chosen location was particularly tight, necessitating meticulous planning and execution to ensure the unit was both unobtrusive and effective.
Technical Elegance: The Gree Free Match Extreme
The Machine Specs:
- Model: Gree Free Match Extreme
- Type: DoubleZone Heat Pump
- Size: 18,000 BTU compressor with two 9,000 BTU indoor units
- Efficiency: 23.0 SEER, Energy Star® rated
- Features: WiFi capability, AHRI Certified (202557965), Low Voltage Start, Anti-Corrosion Coating
- Durability: Extended warranty of 10 years on compressor, parts, and labor
This model stands out with its exceptional 23.0 SEER efficiency rating, ensuring that energy consumption is minimized while maximizing comfort. The system’s capacity to heat up to -35°C makes it a robust ally against the harshest winter temperatures. Equipped with WiFi, the system offers the convenience of remote adjustments, fitting perfectly into the modern smart-home ecosystem.
Installation Ingenuity
Our installation team had to innovate to fit the compressor in such a constrained space. By customizing the mounting and utilizing specialized vibration-dampening technology, we ensured that the unit was not only space-efficient but also operated at a remarkably low noise level of 58 dB(A) – quieter than the average conversation.
Environmental and Economic Benefits
Adhering to the principles of sustainability and cost-efficiency, this installation was also eligible for the $2,040 LogisVert Grant by Hydro-Québec. This not only provided our client with a significant rebate but underscored the environmental benefits of choosing a high-efficiency system like the Gree Free Match Extreme. The use of eco-responsible R410A refrigerant and energy-efficient technologies further aligns with our commitment to environmental stewardship.

The big day, step by step
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What would it look like at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.

Your own project, step by step
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
