A residential installation designed for four-season comfort in Montreal’s West Island
In L’Île-Perrot, homeowners are increasingly seeking efficient heating and cooling solutions capable of meeting the significant variations in Quebec’s climate. Summer cooling alone is no longer enough: residents now want a unit that can cool the house during hot periods while providing economical heating when temperatures drop.
During this installation carried out by AirGreen, our team installed a ForestAir E24 wall-mounted heat pump in a residence in L’Île-Perrot. The project aimed to improve indoor comfort while providing a more energy-efficient solution than a traditional air conditioner.
The installed indoor unit, visible in the project photos, features a discreet white finish that blends easily into the room’s decor. Positioned high on the wall, near the ceiling, it allows for better air distribution and more even circulation throughout the living space.
At AirGreen, we pay close attention to every detail of an HVAC installation, because a heat pump’s performance depends as much on the choice of unit as on the quality of its installation.
Why choose a ForestAir E24 wall-mounted heat pump for a home in L’Île-Perrot?
A solution tailored to the needs of Quebec homeowners
The ForestAir E24 is one of the wall-mounted heat pumps designed to deliver high performance in Quebec’s climate conditions. Unlike a conventional wall-mounted air conditioner, a wall-mounted heat pump operates in both directions:
- it removes heat from the house during summer;
- it recovers the energy present in the outdoor air during winter;
- it reduces the use of the main electric heating system;
- it improves occupant comfort throughout the year.
For a residence in L’Île-Perrot, where winters can be harsh and summers hot and humid, this type of unit is a versatile option.
The capacity of the ForestAir E24 range makes it possible to effectively meet the needs of a wide variety of residential properties, including single-family homes, condos, and additions requiring an independent comfort zone.
Technology designed for cold climates
One of the important criteria when choosing a heat pump in Quebec is its ability to maintain acceptable performance as the outdoor temperature drops.
A good cold-climate heat pump must be able to operate efficiently during the periods when homeowners actually use their heating system.
The ForestAir E24 offers, among other features:
- inverter technology that automatically adjusts the compressor’s power;
- quieter operation than a traditional on/off system;
- greater temperature stability;
- reduced electricity consumption thanks to continuous adjustment to demand.
This modulation prevents frequent starts and improves the comfort felt throughout the home.
The features of the installation carried out by AirGreen in L’Île-Perrot
Location analysis before installation
Before any wall-mounted heat pump installation, our technicians assess several factors:
- the size of the room;
- natural air circulation;
- the ideal location for the indoor unit;
- the distance between the indoor and outdoor units;
- the passage of the refrigerant lines;
- condensate drainage.
For this project in L’Île-Perrot, the goal was to achieve a visually clean installation while maximizing air distribution.
The indoor unit was installed high on the wall to allow warm or cool air to be distributed efficiently throughout the room. This position also promotes better operation in heating mode, since warm air can naturally descend toward the occupied area.
A clean and discreet finish
A professional installation is not limited to mounting a unit on the wall. Finishing details play an important role in the final appearance.
At AirGreen, we pay particular attention to:
- indoor unit alignment;
- aesthetic management of the lines;
- wall protection;
- job-site cleanliness;
- final operating tests.
In this installation, the ForestAir wall-mounted unit retains a modern, minimalist appearance. Its white front panel blends naturally into a residential setting without creating an excessive visual presence.
Commissioning and technical checks
After the mechanical installation, our team performs several checks:
- refrigerant circuit leak-tightness check;
- operating pressure check;
- condensation drainage validation;
- cooling mode test;
- heating mode test;
- remote control and main function check.
This step is essential to ensure the long-term reliability of the ForestAir heat pump.
Common mistakes to avoid when installing a wall-mounted heat pump
Choosing solely based on the purchase price
A less expensive heat pump is not always the best solution. Actual performance depends on several factors:
- the quality of the unit;
- the capacity suited to the home;
- the chosen location;
- the quality of the installation;
- the available after-sales service.
Poor selection can lead to:
- insufficient heating in winter;
- higher electricity consumption;
- inefficient operating cycles;
- a reduced compressor lifespan.
Installing the indoor unit in the wrong location
Even an excellent machine can operate less efficiently if it is poorly positioned.
Some common mistakes:
- install the unit behind a piece of furniture;
- choose a location where air does not circulate freely;
- place the unit too close to an obstacle;
- neglect heat distribution in neighboring rooms.
An HVAC installer’s expertise helps prevent these problems from the outset.
Neglecting HVAC maintenance
Like any mechanical equipment, a heat pump requires regular maintenance.
Professional maintenance generally includes:
- filter cleaning;
- indoor heat exchanger inspection;
- fan cleaning;
- drainage inspection;
- overall operation control.
Regular HVAC maintenance helps maintain:
- better air quality;
- reduced energy consumption;
- better performance season after season.
The benefits of a ForestAir wall-mounted heat pump installed by AirGreen
Local expertise adapted to the conditions in Montréal and the surrounding areas
AirGreen installs wall-mounted heat pumps in Montréal, Laval, Longueuil, the North Shore, and the South Shore. Each area has its own characteristics: construction type, insulation, sun exposure, and heating habits.
Our approach is to recommend a solution suited to the building rather than a single model for every situation.
In L’Île-Perrot, many homes have different configurations: older houses, recent constructions, additions, or open spaces. A pre-installation assessment helps determine the best approach.
Professional installation to maximize lifespan
The lifespan of a heat pump depends heavily on its initial installation.
A properly completed installation provides:
- better refrigerant circulation;
- adequate system pressure;
- quieter operation;
- fewer risks of premature problems.
At AirGreen, we consider every project a complete HVAC system installation, not simply the installation of a wall-mounted unit.

This ForestAir E24 installation in L’Île-Perrot demonstrates the importance of balancing technology, energy efficiency, and installation quality.
For homeowners who want to improve their comfort without completely replacing their existing system, a wall-mounted heat pump is often an advantageous solution. It provides efficient air conditioning in summer and additional heating during the colder seasons.
With proper planning, professional installation, and regular maintenance, a system like the ForestAir E24 can provide several years of reliable comfort.
AirGreen supports homeowners in Montréal, Laval, Longueuil, the North Shore, and the South Shore with their heating, ventilation, and air conditioning system installation, replacement, and maintenance projects.
The job tools
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.

What we check on a job like this one
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.
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.

The right pages, at the right time
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.
