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 maximize the comfort of a home in Les Cèdres
At AirGreen, we regularly carry out installations of ductless heat pumps adapted to Quebec’s climate, particularly in the areas of Les Cèdres, Vaudreuil-Soulanges, Montreal, Laval, Longueuil, the North Shore, and the South Shore. Every project has its own particularities: outdoor unit location, architectural constraints, airflow, electrical supply, and the pursuit of the best energy efficiency.
This installation in Les Cèdres showcases a ForestAir E24 ductless heat pump, a solution designed to provide efficient heating in winter while ensuring comfortable cooling during the warmer months of the year.
Upon examining the installation, several elements demonstrate the importance of a professional approach: the outdoor unit was installed on an elevated aluminum structure, securely anchored to the ground, with vibration-dampening supports to limit noise transmission to the home. Its positioning against the brick wall was also carefully planned to ensure good airflow around the condenser.
A ForestAir E24 heat pump suited to Quebec winters
The ForestAir E24 is one of the models favored by homeowners looking for a high-efficiency ductless heat pump capable of operating in Quebec’s winter conditions.
This model uses inverter technology, allowing the compressor to adjust its output according to the home’s actual needs. Unlike older systems that constantly start and stop, an inverter heat pump modulates its operation to maintain a more stable temperature.
Technical specifications of the ForestAir E24
The ForestAir E24 installed in Les Cèdres offers, among other features:
- Rated capacity: 12,000 BTU/h
- Variable-speed inverter technology
- Low-global-warming-potential R-454B refrigerant
- Heating and cooling function
- High energy rating with ENERGY STAR® certification
- Operation adapted to Quebec’s cold climate

This 12,000 BTU/h capacity is especially suitable for spaces requiring efficient heating and cooling, such as medium-sized homes, additions, specific floors, or areas where the existing heating system is not sufficiently effective.
An outdoor installation completed with particular attention to detail
Installing a wall-mounted heat pump in Les Cèdres is not simply a matter of mounting a unit on a wall. The quality of the work depends heavily on the equipment’s positioning and the methods used.
In this project, the ForestAir outdoor unit was installed on a raised metal base. This configuration offers several important advantages:
Protection against snow and ice
In Quebec, snow accumulation can significantly reduce the performance of a poorly positioned heat pump. A unit placed too close to the ground may be affected by:
- snow accumulation around the fan;
- ice from defrost cycles;
- improper drainage of condensation water.
The structure used in this installation keeps a safe distance between the unit and the ground, thereby improving natural drainage and reducing risks associated with winter conditions.
Vibration and noise reduction
Another visible feature of this installation is the use of brackets designed to stabilize the equipment.
A modern inverter heat pump is generally quiet, but improper mechanical installation can cause:
- vibrations transmitted to the building;
- resonance noises in the walls;
- premature wear of certain components.
At AirGreen, we pay particular attention to these details so that the daily operation of the wall-mounted heat pump remains quiet.
Common challenges when installing a wall-mounted heat pump in Quebec
Even when an installation seems simple, several factors must be analyzed before proceeding.
Choosing the right location for the outdoor unit
For this installation in Les Cèdres, the location near the exterior wall offered several advantages:
- easy access for HVAC maintenance;
- partial protection from the elements;
- optimized refrigerant line length;
- sufficient clearance for air circulation.
An unsuitable location can reduce energy efficiency and increase annual electricity consumption.
Respect the required clearances
Manufacturers generally recommend maintaining clearances around the outdoor unit so the fan can properly expel air.
Before each installation, our technicians check:
- distance from the walls;
- surrounding obstacles;
- exposure to wind;
- the space required for future servicing.
This step is essential for maintaining the performance stated by the manufacturer.
Why choose a ForestAir E24 wall-mounted heat pump for a residence in Les Cèdres?
Quebec homeowners generally look for three main features when choosing a wall-mounted heat pump:
- Consistent comfort in both summer and winter.
- Reduced energy consumption.
- A reliable unit requiring minimal service.
The ForestAir E24 meets these needs with its inverter technology and modulation capacity.
More economical heating
For several months of the year, a heat pump can replace or reduce the use of a traditional electric heating system.
Its operating principle differs from that of an electric baseboard heater: it transfers the heat present in the outdoor air into the home. Even when temperatures drop below freezing, a cold-climate heat pump can continue to provide effective heat.
Comfortable air conditioning in summer
During the hot and humid days in Montreal and the Montérégie, the ForestAir E24 also helps maintain a comfortable indoor temperature.
Inverter modulation helps avoid the large temperature fluctuations often associated with traditional air conditioners.

Recommended maintenance for a ForestAir E24 heat pump
Even a high-quality heat pump requires regular maintenance.
To maintain optimal performance, we recommend:
Indoor filter maintenance
Filters must be cleaned regularly to prevent:
- reduced airflow;
- higher electricity consumption;
- dust buildup in the indoor unit.
Regular professional cleaning
Professional HVAC maintenance makes it possible to check:
- fan condition;
- coil cleanliness;
- condensate drainage;
- operating parameters;
- system pressures.
A well-maintained unit can maintain its performance for many years.
