Installation of a Gree FreeMatch wall-mounted heat pump in Rosemont–La Petite-Patrie (Montreal)
In Rosemont–La Petite-Patrie, AirGreen installed a Gree FreeMatch wall-mounted heat pump in a high position for even heat distribution, a discreet finish, and reliable summer/winter comfort. Discover the installation details and our maintenance tips.

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.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
Many apartments in Rosemont–La Petite-Patrie feature rooms of varying sizes, walls with moldings, built-in storage, and sometimes limited free space for installing a wall unit in the right location. This is precisely the kind of situation where an HVAC system must be carefully planned: comfort, quiet operation, aesthetics , and performance in both summer and winter.
For this project, our team installed a Gree FreeMatch wall-mounted heat pump , a reliable and flexible solution, particularly suited to Montreal interiors where every detail counts.
A discreet system, installed where it works best
In the photo, the indoor unit is installed very high on the wall , close to the ceiling, with minimal but compliant clearance, and a logical positioning in relation to the space. This choice is never "random":
-
The taller the unit, the more evenly it distributes air throughout the room.
-
Direct airflow to the face is avoided, which improves comfort.
-
We keep the wall available for furniture, especially when the room is already “full” (wardrobes, doors, frames, etc.).
In this specific case, the presence of dark moldings and woodwork indicates an interior where visual integration is important: a clean installation should be unobtrusive.
Machine type: wall-mounted heat pump (mini-split)
Although “FreeMatch” often refers to a multi-zone platform, the configuration observed here is that of a wall-mounted indoor unit (mini-split): horizontal format, diffusion shutter, digital display, high installation.
✅ Selected type: Wall-mounted heat pump (mini-split / wall unit)
✅ Brand: Gree FreeMatch (brand provided manually, used as a reference)
Model (consistent with the range)
Since the exact model is not legible on the unit, we are deliberately sticking with a reliable and realistic identification: Gree FreeMatch – new generation wall unit (wall system compatible with 1 zone or multi-zone configurations depending on the overall project design).
The typical constraints of living in Rosemont… and how to manage them
This type of part often presents very specific constraints:
1) Limited wall space and presence of woodwork
Between the cabinets, doors, and moldings, you need to find the right section of wall to:
-
respect the recommended clearances,
-
allow the front panel to be opened (maintenance),
-
to ensure unobstructed diffusion.
Here, the installation close to the ceiling allows the use of otherwise “wasted” space while maximizing performance.
2) Refrigerant line management and finishing
A beautiful installation is also one that is visually clean . In an interior with distinctive finishes, the aim is to:
-
a logical path for the lines,
-
a planned outdoor outing (without improvisation),
-
a finish that does not “break” the style of the room.
3) Condensation drainage
In air conditioning mode, a heat pump produces condensation. In residential settings, this is a critical point: poorly designed drainage can cause drips, marks on the wall, or dampness.
At AirGreen, we systematically secure:
-
the slope and stability of the drainage,
-
reflux prevention
-
reliability in hot and humid conditions (Montreal in July/August, we know).
Why a Gree FreeMatch is a good choice here
In an area like Rosemont, the needs often boil down to this: quick comfort , stable operation, good performance and low noise level.
A Gree FreeMatch wall-mounted heat pump meets these expectations, particularly because:
-
It allows for precise temperature control (and a rapid response).
-
It fits easily into rooms where the heating is not uniform.
-
It improves summer comfort without resorting to noisy temporary solutions.
-
It offers a flexible base if, later, you want to consider the comfort of other areas (depending on the system configuration).
What the customer notices from the very first days
After an installation like this, the feedback is usually very concrete:
-
The room becomes more stable (less “too hot / too cold”).
-
The air conditioning is efficient and quiet , especially in the evening.
-
You feel a better quality of comfort on a daily basis, even in the mid-season.
-
We use fewer supplementary solutions (fans, temporary heaters).
In short: an immediate, but above all lasting, improvement.
Maintenance tips to maintain performance
A wall-mounted heat pump performs well for a long time… if you give it a little help. Our simple recommendations:
-
Clean the filters regularly (every 4 to 8 weeks).
-
Keep the unit clear (no curtains blocking the airflow).
-
Monitor for: decreased flow rate, odor, unusual noise.
-
Perform a complete periodic maintenance (deep cleaning + technical checks).
This is the best way to preserve: yield, air quality and longevity.
AirGreen: an installation designed for comfort… and aesthetics
In neighborhoods like Rosemont–La Petite-Patrie , the installation must be as carefully designed as the housing itself. Our role is to deliver a system that:
-
works perfectly.
-
integrates neatly,
-
and remains simple to use on a daily basis.
With this Gree FreeMatch wall-mounted heat pump , the customer gets a discreet, efficient solution adapted to the realities of Montreal.
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.
