A compact, high-performance heat pump installation adapted to the constraints of a building in Coteau-du-Lac
At AirGreen, we regularly install wall-mounted heat pumps in environments where available space, the location of the outdoor unit, and architectural constraints require careful planning. This installation in Coteau-du-Lac perfectly illustrates our approach: providing an efficient heating and cooling solution while respecting the building’s specific characteristics.
For this project, our team installed a FORESTAIR E24 wall-mounted heat pump, a model designed to meet the needs of homeowners looking for a reliable, economical unit suited to Quebec’s climate conditions.
The outdoor unit was positioned on a technical surface with an elevated support that provides adequate clearance around the unit. As can be seen in the installation, the heat pump rests on a metal structure that facilitates air circulation, limits ice buildup, and improves access during HVAC maintenance.
This configuration is particularly well suited to areas such as Coteau-du-Lac, Montreal, Laval, Longueuil, the North Shore, and the South Shore, where many homes have exterior layout constraints, balconies, technical roofs, or limited space.
FORESTAIR E24: a wall-mounted heat pump designed for Quebec’s climate
The FORESTAIR E24 belongs to a new generation of wall-mounted heat pumps designed to provide a balance between energy efficiency, residential comfort, and reasonable installation costs.
This model uses R-454B refrigerant, a newer technology that is gradually replacing certain traditional refrigerants due to its reduced environmental impact. The FORESTAIR E24 is therefore an interesting option for homeowners who want to modernize their heating and cooling system.
Main technical specifications of the FORESTAIR E24
- Type of unit: wall-mounted mini-split heat pump
- Brand: FORESTAIR
- Model: E24
- Nominal capacity: approximately 12,000 BTU/h
- Refrigerant: R-454B
- Cooling performance: up to approximately 24 SEER, depending on the certified configuration
- Winter operation: designed to maintain effective heating capacity during cold periods
- Application: residential heating and cooling
Thanks to its design adapted to Quebec’s varying temperatures, this heat pump reduces the use of other heating sources for much of the year.
For many homeowners, a high-efficiency ductless heat pump is a practical way to improve indoor comfort while reducing energy costs associated with electric heating.
A Precisely Executed HVAC Installation Despite Location Constraints
Strategic Positioning of the Outdoor Unit
When installing a heat pump, the location of the outdoor unit plays an essential role in the system’s long-term performance.
In this project in Coteau-du-Lac, our team had to take several factors into account:
- ensure sufficient clearance in front of the outdoor coil;
- avoid areas prone to accumulating snow or ice;
- limit vibration transmission;
- maintain easy access for future maintenance;
- protect the unit from outdoor conditions.
The FORESTAIR E24 outdoor unit was therefore installed on an elevated structure. This method leaves open space beneath the unit to facilitate drainage of water from defrost cycles.
During Quebec winters, a heat pump naturally produces water when it runs a defrost cycle. Improper installation can cause ice to accumulate beneath the unit, which may interfere with operation and shorten the lifespan of the components.
At AirGreen, we pay particular attention to these details, which are not always visible after installation but directly influence the system’s reliability.
Vibration and noise management: an essential consideration in residential settings
A modern heat pump is designed to operate quietly, but improper installation can transmit vibrations to the building structure.
In this installation, choosing a suitable support makes it possible to:
- further isolate the unit from the structure;
- reduce mechanical vibrations;
- improve occupants’ acoustic comfort;
- to facilitate technical work.
This attention is particularly important for installations on balconies, terraces, exterior walls, or structures close to living spaces.
A professional wall-mounted heat pump installation involves more than simply mounting a unit on the wall and connecting lines. Positioning, supports, condensate drainage, and airflow are integral to a durable installation.

Site assessment and installation preparation
Before each project, our team analyzes the building’s characteristics to determine the best possible configuration.
We assess in particular:
- the ideal location of the indoor unit;
- the route of the refrigerant lines;
- the distance between the indoor and outdoor units;
- condensate drainage options;
- the available electrical supply;
- architectural constraints.
This step helps avoid unnecessary modifications and ensures a clean installation.
Installation of the FORESTAIR outdoor unit
The outdoor installation includes several technical operations:
- Installing the appropriate support.
- Precise positioning of the outdoor unit.
- Leveling the unit.
- Installation of the refrigerant lines.
- Electrical connection according to applicable standards.
- Checking the circuit for leaks.
- Commissioning and performance testing.
Each connection must be made precisely to ensure the energy performance advertised by the manufacturer.
Commissioning and final checks
Once the installation is complete, our technicians perform the necessary checks:
- system pressure check;
- verification of operation in heating mode;
- verification of operation in cooling mode;
- supply air temperature check;
- general inspection of the installation.
This final step confirms that the FORESTAIR E24 heat pump is operating properly from the first use.
Why choose a FORESTAIR wall-mounted heat pump for a home in Quebec?
A solution tailored to homeowners’ needs
Homeowners replacing an old air conditioner or looking for an additional heating solution often choose a wall-mounted heat pump for several reasons:
- effective heating during the colder seasons;
- comfortable air conditioning during the summer;
- reduced electricity consumption;
- less invasive installation than a central system;
- precise temperature control.
In many homes in Coteau-du-Lac and the surrounding areas, a wall-mounted heat pump is a practical solution when ventilation ducts are not present.
An interesting alternative to traditional air conditioners
A conventional wall-mounted air conditioner only provides cooling. A wall-mounted heat pump, on the other hand, can also provide heating.
This difference is important in Quebec because the unit can operate during the transition periods:
- spring;
- fall;
- milder winter days.
This often helps reduce demand on the home’s primary heating system.
Common mistakes to avoid when installing a wall-mounted heat pump
A successful installation depends as much on choosing the right unit as it does on the quality of the installation.
Here are some common mistakes we observe in the HVAC field:
Choosing an unsuitable capacity
A heat pump that is too small may run constantly without achieving the desired comfort level. An oversized unit may cause short cycling and reduce efficiency.
Sizing must take into account:
- floor area;
- insulation;
- sun exposure;
- the interior layout;
- the occupants’ habits.
Neglecting the outdoor unit’s location
Installing an outdoor unit in an overly enclosed space or without sufficient clearance can reduce its performance.
A proper installation must allow air to circulate freely.
Forgetting the annual maintenance
Even a high-performance heat pump requires regular maintenance.
Professional HVAC maintenance helps:
- clean the heat exchangers;
- check the drains;
- monitor performance;
- extend the system’s lifespan.
At AirGreen, we recommend periodic maintenance to maintain your equipment’s efficiency.
