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 wall-mounted heat pump installation tailored to the needs of a Saint-Clet residence
In Saint-Clet, in the Vaudreuil-Soulanges region, homeowners seek heating and cooling solutions capable of providing consistent comfort despite Quebec’s significant temperature variations. A comfortable home in both summer and winter now requires reliable, quiet, and properly sized equipment.
During this installation carried out by AirGreen, our team installed a ForestAir E24 wall-mounted heat pump to improve the comfort of a residence while reducing dependence on traditional electric heating.
This installation features several noteworthy elements visible in the project photos. The ForestAir outdoor unit was installed in an indoor parking area in an underground garage, on a raised metal structure allowing better air circulation around the unit. The refrigerant lines and wiring were routed neatly to the exterior wall, with particular attention paid to the finish and protection of the components.
At AirGreen, we believe that installing a wall-mounted heat pump involves more than simply mounting a unit and connecting a few lines. Every detail affects performance, durability, and the comfort achieved by the homeowner.
A ForestAir E24 designed to meet Quebec’s climate conditions
A wall-mounted heat pump offering four-season heating and cooling
The ForestAir E24 installed in Saint-Clet belongs to a category of wall-mounted heat pumps designed for Quebec residences requiring a versatile solution.
Unlike a simple wall-mounted air conditioner, a heat pump can provide cooling in summer and transfer outdoor heat indoors during the cold season.
The main benefits sought with this type of installation are:
- efficient cooling during hot and humid periods;
- economical supplemental heating in winter;
- quiet operation thanks to inverter technology;
- greater temperature stability;
- optimized energy consumption.
For a residence located in Saint-Clet, where winter temperatures can drop well below freezing, choosing a heat pump suited to cold climates is essential.
The technical specifications of the ForestAir E24
The ForestAir E24 series uses modern technology that allows the compressor to adjust its output according to the home's actual needs.
This modulation offers several benefits:
- fewer abrupt starts and stops;
- more precise maintenance of indoor temperature;
- quieter operation;
- better annual energy efficiency.
The E24 model uses R-454B refrigerant, a newer generation of refrigerant designed to reduce environmental impact while maintaining good thermal performance.
According to the data available for this model, the ForestAir E24 heat pump offers a nominal capacity of 12,000 BTU/h with high energy efficiency, making it particularly suitable for residential spaces requiring an independent comfort zone.
A professional HVAC installation carried out in a unique environment in Saint-Clet
Installation of the outdoor unit in an indoor parking area
One of the distinctive elements of this project is the location of the outdoor unit.
For this installation, the ForestAir unit was positioned in an indoor parking area. This type of configuration requires careful analysis, since heat pumps need sufficient airflow around the outdoor heat exchanger.
Our team must therefore pay attention to several aspects:
- clearance around the unit;
- discharge of expelled air;
- access for future maintenance;
- mechanical protection against impacts;
- safe installation on a support.
The metal structure used keeps the unit elevated and stable. This approach also facilitates any future maintenance and limits direct contact with the ground.
Professional Refrigerant Line Management
A quality installation also depends on the invisible work behind the unit.
The lines connecting the indoor and outdoor units must be installed precisely to ensure:
- proper refrigerant circulation;
- reduced performance losses;
- vibration protection;
- a clean finish.
At AirGreen, we always perform the necessary checks before commissioning:
- refrigeration circuit inspection;
- leak test;
- compressor operation check;
- validation of heating and cooling modes;
- condensate drainage verification.
These steps ensure that the ForestAir heat pump operates according to the parameters specified by the manufacturer.
Why Professional Installation Is Just as Important as Choosing the Model
A good heat pump can lose a significant amount of performance if it is improperly installed
When a homeowner chooses a new wall-mounted heat pump in Montreal, Laval, Longueuil, the North Shore, or the South Shore, several factors are often compared:
- price;
- brand;
- capacity;
- warranty;
- energy efficiency.
However, installation quality plays an equally important role.
An improper installation can cause:
- insufficient heating during cold days;
- higher electricity consumption;
- drainage problems;
- excessive noise;
- premature compressor wear.
That is why AirGreen places great importance on analyzing the building before even recommending a unit.
Adapting the Heat Pump to Each Home’s Reality
Every residence has its own particularities:
- different insulation;
- room orientation;
- ceiling height;
- number of occupants;
- heating habits.
In Saint-Clet, as elsewhere in the Montreal and Montérégie regions, an effective installation begins with a genuine understanding of the homeowner’s needs.
A high-capacity heat pump installed in the wrong location can deliver inferior results compared with a properly selected and positioned unit.
HVAC Maintenance: Preserving the Performance of the ForestAir E24
Once the installation is complete, maintenance remains an important step in preserving the system’s performance.
Regular maintenance of a wall-mounted heat pump includes, among other things:
- indoor filter cleaning;
- heat exchanger cleaning;
- fan inspection;
- condensate drain inspection;
- overall operation check.
In a Quebec environment, the outdoor unit of the heat pump is exposed to:
- snow;
- ice;
- dust;
- pollen;
- significant temperature fluctuations.
Professional HVAC maintenance helps reduce the risk of efficiency losses and maintain better comfort year after year.

A professional installation combines:
- proper equipment selection;
- precise planning;
- a clean installation;
- comprehensive testing;
- post-commissioning support.

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.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced 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.
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.
