An awning installation adapted to the realities of a Quebec residence in Saint-Polycarpe
At AirGreen, every ductless heat pump installation is planned according to the building’s actual environment. The outdoor unit’s location, airflow, protection from the elements, and accessibility for HVAC maintenance are factors that directly influence a system’s performance and lifespan.
This installation, completed in Saint-Polycarpe, in the Vaudreuil-Soulanges region, presents a particular configuration: the outdoor unit of a ForestAir E24 ductless heat pump was installed beneath an awning, immediately beside an exterior door. This situation required technical consideration to ensure reliable operation while maintaining a clean and discreet installation.
The ForestAir E24 offers a complete heating and cooling solution for homeowners who want to improve their comfort during hot summers and enjoy more efficient heating during the colder seasons. For a home located in Saint-Polycarpe, as throughout the South Shore, a unit’s ability to operate in Quebec’s variable climate is an essential factor.

A unit designed for the residential needs of Quebec
The selection of a heat pump should never be based solely on the purchase price. Sizing, energy efficiency, the technology used, and installation quality play a major role in homeowner satisfaction.
The ForestAir E24 ductless heat pump installed in Saint-Polycarpe meets the needs of a residential home seeking:
- effective air conditioning during the summer;
- more economical electric heating than using baseboard heaters exclusively;
- quiet operation;
- better temperature stability in the main rooms;
- optimized energy consumption thanks to inverter technology.
Unlike a traditional wall-mounted air conditioner, a wall-mounted heat pump can operate in both directions. It extracts heat from outdoors to heat the interior in winter and reverses its cycle to remove indoor heat during summer.
This versatility explains why many homeowners in Montreal, Laval, Longueuil, North Shore and South Shore are now choosing this technology to modernize their HVAC systems.
Technical specifications of the ForestAir E24
The ForestAir E24 belongs to a new generation of units designed to provide improved energy efficiency and operation suited to Canadian climate conditions.
The main features of this equipment include:
- Brand: ForestAir
- Model: E24
- Type: ductless wall-mounted heat pump
- Capacity: approximately 12,000 BTU
- Technology: variable-speed inverter compressor
- Refrigerant: R-454B
- Operation: heating and cooling
The R-454B refrigerant represents an important transition in the HVAC industry. It is used in several new systems to reduce the environmental impact associated with refrigerants from previous generations.
For the homeowner, this means installing a unit designed to meet the market’s new standards, with technology suited to the coming years.
An under-awning installation that required careful planning
Why the outdoor unit’s location matters
When a wall-mounted heat pump is installed, the outdoor unit must be able to discharge and draw in large quantities of air. An unsuitable location can affect:
- heating performance;
- cooling efficiency;
- defrost cycles;
- the compressor’s lifespan.
For this installation in Saint-Polycarpe, the ForestAir outdoor unit was positioned beneath a protective structure. This configuration offers several advantages:
- protection from direct precipitation;
- reduced exposure to heavy snow accumulation;
- better overall protection for the unit.
However, an installation under a balcony or awning requires special attention. The space available above the unit must allow for proper discharge of hot air in cooling mode and cold air during winter operating cycles.
At AirGreen, we always assess these constraints before installation to prevent air recirculation problems or efficiency losses.
Using suitable wall brackets
One of the important details visible in this installation is the use of metal brackets secured to the building’s structure.
This type of bracket offers several advantages:
- keep the outdoor unit at a safe height;
- prevent direct contact with the ground;
- make it easier to drain defrost water;
- protect the unit from certain accumulations of ice or snow.
In several areas of the Montreal South Shore, installations on brackets are particularly useful when ground space is limited or when the homeowner wants to keep a terrace, driveway, or passageway clear.
The steps carried out by AirGreen during this HVAC installation
Location analysis and site preparation
Before any wall-mounted heat pump installation, our team checks several elements:
- the available structure for securing the brackets;
- the routing of the refrigeration lines;
- the ideal location for the indoor unit;
- the distance between the components;
- the available electrical supply.
In a home in Saint-Polycarpe, these checks make it possible to adapt the installation to the building’s actual characteristics rather than applying a standard solution.
Equipment installation and connection
A professional installation involves several technical steps:
- Securely mounting the outdoor unit.
- Installing the insulated refrigeration lines.
- Connecting the electrical wiring according to the manufacturer’s requirements.
- Installing the condensate drain.
- Evacuating the refrigeration circuit.
- Checking the pressures and operation.
- Explaining how it works to the homeowner.
Every step directly affects the system’s reliability.
A high-performance heat pump can lose some of its efficiency if it is not installed properly. That is why the installer’s expertise is just as important as the choice of brand.
Common mistakes when installing a wall-mounted heat pump
Installing the outdoor unit without considering its surroundings
A common mistake is choosing a location based solely on its visual appearance.
An outdoor unit must have:
- enough space to breathe;
- access for future service;
- reasonable protection from the elements;
- adequate water drainage.
An aesthetically pleasing but technically inadequate installation can lead to problems after a few seasons.
Neglecting annual HVAC maintenance
Even a modern heat pump requires regular maintenance.
We recommend:
- indoor filter cleaning;
- indoor fan inspection;
- heat exchanger cleaning;
- outdoor unit inspection;
- heating performance check.
Professional HVAC maintenance helps maintain energy performance and reduces the risk of costly breakdowns.
Financial assistance available for an energy-efficient heat pump
Homeowners in Saint-Polycarpe may sometimes qualify for financial assistance programs for installing an eligible heat pump.
The criteria vary by program:
- installed model;
- energy certification;
- type of residence;
- building conditions;
- administrative requirements.
At AirGreen, we inform our customers about the available options before finalizing their HVAC installation project.
Good planning makes it possible to understand not only the purchase and installation price, but also the potential savings associated with improved energy efficiency.
AirGreen expertise for installations in Saint-Polycarpe, Montreal, and the surrounding areas
A successful installation relies on several elements: the right unit, a proper building assessment, and professional execution.
This installation of a ForestAir E24 in Saint-Polycarpe demonstrates the importance of adapting each project to its environment. The installation beneath an awning, the use of wall brackets, and the attention paid to clearances show that a wall-mounted heat pump must be designed as a complete system, not simply as a unit mounted on a wall.
At AirGreen, we install wall-mounted heat pumps, wall-mounted air conditioners, and heating systems throughout the Greater Montreal area, including Laval, Longueuil, the North Shore, and the South Shore.
Our approach is to provide sustainable, properly sized HVAC solutions installed according to industry best practices.
The job tools
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 we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.

The right pages, at the right time
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.
