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 completed with precision for four-season comfort in Montérégie
At AirGreen, we install wall-mounted heat pumps tailored to the actual needs of homeowners throughout Greater Montreal, including Montérégie, the South Shore, the North Shore, Laval, and Longueuil. Every project has its own particularities: the home's layout, available space for the outdoor unit, architectural constraints, and comfort goals.
This installation in Saint-Urbain-Premier is an excellent example of a residential project where choosing a ForestAir E24 wall-mounted heat pump provides an effective solution for both summer cooling and heating during cold periods.
Our team installed a ForestAir E24 outdoor unit against a brick façade, paying particular attention to the stability of the support, the routing of the refrigerant lines, and the aesthetic integration of the entire system. The result is a clean, discreet installation designed to operate efficiently for many years.
A ForestAir E24 heat pump suited to Quebec conditions
A complete HVAC solution to replace or reduce the use of electric baseboard heaters
Unlike a simple wall-mounted air conditioner, a wall-mounted heat pump offers two essential functions: cooling in summer and heating in winter.
For several homes in Saint-Urbain-Premier and surrounding municipalities, this technology represents a significant improvement in indoor comfort. During the warm season, the unit removes heat from the home to maintain a pleasant temperature. When outdoor temperatures drop, the heat pump reverses its operation to capture the heat available in the outdoor air and transfer it indoors.
The ForestAir E24 12,000 BTU installed by AirGreen is particularly well suited to the needs of homeowners seeking:
- Efficient cooling during the summer;
- High-performance supplemental heating during the fall and winter;
- Better-controlled energy consumption;
- A solution adapted to the Quebec climate.
Technical specifications of the ForestAir E24
The ForestAir E24 is one of the wall-mounted heat pump models designed to offer a good balance of performance, energy efficiency, and reliability.
The main features of this model include:
- Capacity of 12,000 BTU/h;
- Inverter technology allowing the compressor to adjust its output according to demand;
- Next-generation refrigerant R-454B;
- Energy efficiency of up to approximately 24 SEER;
- Heating operation down to approximately -25 °C;
- Design adapted to Quebec residential installations.
Choosing a capacity of 12,000 BTU is not based solely on the size of a room. At AirGreen, we analyze several factors before recommending an installation: insulation, building orientation, ceiling height, sun exposure, interior layout, and occupants’ habits.
A properly sized heat pump provides greater comfort, more stable operation, and a longer component lifespan.
The details of this wall-mounted heat pump installation in Saint-Urbain-Premier
Outdoor installation on a brick façade with a meticulous finish
One of the important visible elements of this installation is the location of the ForestAir E24 outdoor unit.
Installing a heat pump on a brick façade requires a precise method to ensure the installation is secure while preventing excessive vibration transmission to the building structure.
Our technicians pay particular attention to the following elements:
- Choosing a location that allows for good air circulation;
- Secure fastening of the supports;
- Vibration reduction;
- Compliance with the distances recommended by the manufacturer;
- Protection of the lines against the elements.
For this installation, the refrigerant lines and wiring were protected to maintain a clean appearance while ensuring lasting protection against outdoor conditions.
A professional HVAC installation involves more than simply connecting a machine. Installation quality directly affects the equipment’s performance, noise level, and service life.
An installation designed for Quebec winters
In Quebec, an outdoor heat pump must be installed with winter conditions in mind.
During defrost cycles, the outdoor unit produces water that must be able to drain properly. Poor drainage management can lead to ice buildup around the unit.
At AirGreen, we check several essential points:
- The stability of the outdoor unit;
- Height above the ground;
- The possibility of draining water;
- Exposure to snow accumulation;
- Future access for HVAC maintenance.
These details may seem minor, but they play an important role in a heat pump’s reliability during the coldest months.
Why choose a ForestAir E24 wall-mounted heat pump?
Better energy efficiency every day
One of the main advantages of a modern heat pump is its ability to provide heating with reduced electricity consumption compared with several traditional systems.
Thanks to inverter technology, the ForestAir E24 continuously adjusts its operation. It avoids the frequent starts and stops of a conventional unit, which helps:
- Maintain a more consistent temperature;
- Reduce comfort fluctuations;
- Optimize electricity consumption.
For homeowners who primarily use electric baseboard heaters, adding a high-efficiency wall-mounted heat pump can significantly improve comfort.
Comfortable air conditioning throughout the summer
During the hot days in Montreal, Montérégie, and neighboring regions, a wall-mounted heat pump helps maintain a comfortable indoor temperature.
The ForestAir E24 offers continuous modulation, which also helps maintain better control of indoor humidity.
A well-air-conditioned home is about more than just temperature. Comfort also depends on thermal stability, air circulation, and quiet equipment operation.
Common mistakes when installing a heat pump
Choosing a unit based solely on price
A less expensive heat pump is not necessarily the best long-term choice.
The following factors must be considered:
- Actual heating capacity;
- Low-temperature performance;
- Parts availability;
- Installation quality;
- After-sales service.
At AirGreen, we prioritize an approach based on compatibility between the equipment and the building.
Neglecting HVAC maintenance
Even a high-performance heat pump requires regular maintenance.
We generally recommend:
- Filter cleaning by the homeowner;
- Periodic inspection of operation;
- Professional cleaning when necessary;
- Checking drainage and performance.
Proper HVAC maintenance helps maintain energy efficiency and reduces the risk of premature problems.
Poor outdoor unit placement
The outdoor unit must have adequate airflow. Installing it too close to an obstacle or in a poorly ventilated space can reduce system performance.
The following factors must be considered:
- Minimum clearances around the unit;
- Snow accumulation;
- Access for technicians;
- Noise level.

And at your place?
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 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.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
