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 FORESTAIR E24 installation designed to provide four-season comfort in a Pointe-Fortune home
At AirGreen, every wall-mounted heat pump installation is adapted to the building's layout, the available space, and the occupants' specific needs. This project in Pointe-Fortune demonstrates the importance of a well-planned HVAC installation, particularly when the outdoor unit must be positioned in a limited space while maintaining optimal airflow.
For this project, our team installed a FORESTAIR E24 wall-mounted heat pump, a system designed to provide efficient heating during Quebec's cold periods and comfortable cooling throughout the summer season.
The installation shown in the photos features several important technical elements: an outdoor unit installed on a sturdy wall bracket, sufficient overhead clearance for proper ventilation, proximity to an exterior door requiring secure fastening, and particular attention to the routing of the refrigerant lines.
In Pointe-Fortune, as in many areas of the North Shore, homes may present various constraints: different exterior claddings, limited space around walls, patios, verandas, or existing structures. A professional installation must therefore take all these factors into account before the work even begins.
A FORESTAIR E24 heat pump adapted to the residential needs of Quebec
The FORESTAIR E24 is a wall-mounted ductless mini-split heat pump that combines cooling and heating in a single unit. This type of system is especially appreciated by homeowners who want to improve their comfort without undertaking the complete installation of a duct network.
Unlike a simple wall-mounted air conditioner, a wall-mounted heat pump can reverse its refrigeration cycle to transfer outdoor heat into the home during the cooler seasons.

- effective air conditioning on hot days;
- a discreet and energy-efficient unit.
For a residence in Pointe-Fortune, a properly sized heat pump can significantly improve indoor comfort while also contributing to better energy consumption management.
Professional HVAC installation adapted to a particular outdoor location
Installation of the outdoor unit on a wall-mounted bracket
One of the most visible aspects of this installation is the positioning of the FORESTAIR outdoor unit above an exterior door.
This configuration requires particular attention because the bracket must be strong enough to support the weight of the unit while limiting vibration transmission to the building structure.
Our team installed the unit on a wall-mounted bracket designed to:
- keep the heat pump level;
- ensure adequate clearance beneath the unit;
- protect the equipment from snow accumulation;
- facilitate water drainage during defrost cycles;
- allow convenient access for future maintenance.
The clearance around an outdoor unit is often underestimated. However, a heat pump needs to draw in and discharge a large amount of air to operate efficiently.
A unit installed too close to an obstacle may lose efficiency, run longer, and experience premature wear.
Particular attention to the exterior cladding and building structure
When a heat pump is installed on an exterior wall with vinyl or similar siding, the fastening method must be adapted.
A common mistake is to simply attach the brackets without checking the structure behind the cladding. A durable installation requires locating the appropriate anchoring points to ensure secure fastening.
At AirGreen, we always analyze:
- the wall structure;
- the position of the studs;
- the strength of the support;
- the location of the lines;
- the installation’s visual impact.
The goal is to achieve a clean, functional, and durable installation.
Drainage management and winter defrost cycles
In Quebec, a heat pump must be able to operate in demanding winter conditions.
During heating, the outdoor unit sometimes accumulates frost. It then automatically performs a defrost cycle that produces water.
Improper installation can cause:
- ice accumulation beneath the unit;
- fan blockage;
- reduced performance;
- unnecessary work.
Positioning the unit on a wall bracket, as in this installation in Pointe-Fortune, offers an important advantage by keeping the unit off the ground.
The steps carried out by AirGreen for this heat pump installation in Pointe-Fortune
Project analysis and preparation
Before installation, our team evaluates several parameters:
- area to be cooled and heated;
- home insulation;
- ideal location for the indoor unit;
- distance between the two units;
- refrigerant line routing;
- available electrical power.
This analysis makes it possible to select a suitable configuration rather than simply installing a unit based on the available space.
Installation and connection of the heat pump
The installation of a FORESTAIR E24 wall-mounted heat pump includes several technical steps:
- Installation of the outdoor bracket.
- Placement of the outdoor unit.
- Installation of the indoor unit.
- Routing of the refrigerant lines.
- Electrical connection.
- Installation of the condensate drain.
- Evacuation of the refrigerant circuit.
- Complete operation check.
Each step directly affects the system's lifespan and efficiency.
Poor evacuation, an improperly executed refrigerant connection, or inadequate drainage management can lead to problems after a few months of use.
Final tests before handing the system over to the owner
Once the work is complete, our technicians perform a series of checks:
- operation in cooling mode;
- operation in heating mode;
- temperature control;
- checking for unusual noises;
- inspection of the connections;
- general installation inspection.
This step confirms that the unit is operating according to the specified parameters.
Why choose a wall-mounted heat pump for a home in Pointe-Fortune?
A practical solution without a duct network
Many homes in Quebec do not have a central system with ventilation ducts.
In these situations, a wall-mounted heat pump is often an effective solution because it does not require major work on the walls or ceilings.
It provides:
- additional heating in winter;
- effective cooling in summer;
- independent temperature control;
- quick installation compared with a central system.
An interesting technology for reducing energy costs
The principle of a heat pump is to move heat rather than simply produce it.
In heating mode, it captures thermal energy from the outdoor air to heat the home.
This technology generally provides higher efficiency than traditional electric resistance heating during many periods of the year.
Actual savings, however, depend on several factors:
- outdoor temperature;
- building insulation;
- occupant habits;
- system settings;
- maintenance completed.
HVAC maintenance: maintaining the performance of your FORESTAIR E24
Even a modern heat pump requires regular maintenance.
Professional HVAC maintenance includes, among other things:
- filter cleaning;
- indoor unit inspection;
- heat exchanger cleaning;
- drainage inspection;
- general operation check.
A clean unit consumes less energy and maintains its heating and cooling capacity more effectively.
At AirGreen, we recommend that homeowners schedule periodic maintenance to maximize their equipment’s lifespan.
Mistakes to avoid when installing a wall-mounted heat pump
Choosing a location based solely on aesthetics
An outdoor unit should be discreet, but performance must remain the priority.
A location that is too enclosed or poorly ventilated can reduce system efficiency.
Neglecting proper sizing
A heat pump must be selected according to the building’s actual needs.
An undersized unit could run constantly without achieving the desired comfort level. An oversized unit could have inefficient cycles.
Entrusting the installation to a non-specialized installer
A heat pump is a complex piece of equipment that combines:
- refrigeration;
- electrical work;
- electronic controls;
- air circulation;
- defrost management.
Professional installation is essential to ensure system reliability.
