The tour

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.

Generic diagram: wall-mounted heat pump, indoor and outdoor units

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.

  1. 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.

  2. The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.

  3. Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.

  4. A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.

  5. The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.

  6. On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.

  7. The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

The job

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 steps

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.

Step 1 of 9The on-site estimate

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.

  1. The on-site estimateWe look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
  2. The quoteModel, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
  3. Getting readyFloors and furniture protected, wall plate position marked level, wall opening located.
  4. The wall openingA single opening, with the slope the drain needs to flow outside.
  5. The outdoor unitSet on a stand raised above the snow, with the clearances the manufacturer requires.
  6. Lines, cable and drainConnected, insulated and protected. The opening is then sealed against water, cold air and insects.
  7. The electrical workA dedicated circuit and an accessible disconnect near the outdoor unit.
  8. Tests and start-upLeak test, vacuum, then start-up and a check of heating and cooling.
  9. The walkthroughRemote, modes, filters: we show you the essentials before we leave.
Your numbers

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.

Size checkYour baseboards, in BTU/h
–BTU/h of installed electric heat

    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.

    Through the seasons

    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.
    At your place

    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.

    0 / 6 checked
    True or false

    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.

    2. You pick the capacity with a simple square-footage rule.

    3. A multi-zone connects several indoor heads to a single condenser.

    4. The disconnect can sit behind the patio furniture.

    Frequently asked questions

    What people ask us about this kind of work

    12 questions
    Does a wall-mounted heat pump heat in winter?
    Yes, it heats and cools. Its capacity drops in very cold weather; the operating range depends on the model and is listed on its spec sheet.
    Wall-mounted or multi-zone: how do I choose?
    One wall head and one condenser outside: the direct solution for a room or an open area. For two to five rooms, a multi-zone puts one head in each room on a single condenser.
    Where does the outdoor unit go?
    Where it stays above the snow, clear and accessible, away from walkways. We decide it with you during the estimate.
    Are there grants?
    Depending on the model and your situation, assistance programs may apply, including Hydro-Québec's LogisVert. AirGreen checks the model number before quoting an amount. See the grants.
    Do I need a permit?
    Rules vary from city to city: location, distances, noise. See permits and by-laws, and we check for your address.
    How cold can it heat?
    It depends on the model. According to Hydro-Québec, newer models work down to a temperature between −15 °C and −25 °C, and some cold-climate models are certified lower. The minimum temperature is on each unit's spec sheet.
    How much can I save?
    Hydro-Québec says a heat pump can be up to three times more efficient than baseboards for heating in the colder months. The result depends on the house, the climate and how it is used.
    How is the LogisVert assistance calculated?
    For ENERGY STAR cold-climate certified heat pumps, Hydro-Québec lists assistance of $120 per 1,000 BTU/h of heating capacity at −8 °C. AirGreen checks the exact model before quoting an amount; only Hydro-Québec confirms the assistance granted. See the grants.
    Is it noisy?
    The sound level depends on the model and is listed in decibels on each unit's spec sheet. Location matters too: when possible, we avoid putting the outdoor unit under a bedroom window.
    The outdoor unit is covered in ice: is that normal?
    Some frost is: the unit runs defrost cycles. Never hit the ice. If the unit stays iced up or stops heating, call us.
    Does AirGreen hold the required licences?
    Yes. AirGreen holds RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration and 16 Electricity.
    Is the estimate free?
    Yes. The on-site estimate is free and the quote follows within 24 hours. Book my free estimate.
