Take a tour of the installation
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.
Optimizing the comfort of a LaSalle home with a Sharp heat pump
At AirGreen , we recently installed a Sharp Eco Inverter wall-mounted heat pump in a single-family home located in LaSalle , on the island of Montreal. This intervention perfectly illustrates our expertise in HVAC installation in residential environments where the needs for thermal comfort, energy efficiency and sustainability are paramount.
The particularities of the project
The owner wanted a reliable, energy-efficient, and durable heating and cooling solution suitable for Montreal's harsh winters. He chose the Sharp Eco Inverter , a model renowned for its Plasmacluster Ion technology, which improves air quality, and its high energy efficiency thanks to intelligent modulation of the compressor speed.
The installation was carried out on an exterior brick wall, typical of LaSalle residences. We fixed the condenser to sturdy wall brackets , at a safe height to avoid snow accumulation in winter, while ensuring optimal air circulation around the unit.
Technical steps of installation
Preparing and fixing the outdoor unit
-
Discreet opening in the foundation wall for the passage of refrigeration pipes.
-
Installation of the condenser on galvanized wall supports with mechanical anchors suitable for masonry.
-
Addition of a painted steel side support to stabilize the assembly and prevent excessive vibration.
Connections and commissioning
-
Passage of insulated ducts in compliance with HVAC standards, with a short and direct route to limit efficiency losses.
-
Electrical connection protected in a waterproof box, compliant with RBQ requirements.
-
Commissioning carried out with pressure and vacuum tests, followed by refrigerant loading and flow calibration.
Advantages of the Sharp Eco Inverter
-
All-season performance : efficient operation in both heating and cooling modes, even during temperature variations specific to the Montreal region.
-
Inverter technology : automatic adjustment of compressor power for significant energy savings.
-
Improved air quality : thanks to the Plasmacluster Ion system, which neutralizes bacteria and allergens.
-
Discretion and comfort : quiet operation, ideal for homes in residential areas like LaSalle.
-
Grant eligibility : Some Sharp heat pump models are eligible for provincial and federal financial assistance programs for energy efficiency.
Challenges encountered and solutions provided
During this project, the available space on the façade was limited by an adjacent metal staircase. To ensure safety and accessibility, we:
-
Opted for a wall installation rather than a floor installation, in order to free up space at ground level.
-
Slightly raised the outdoor unit to avoid any future obstructions and improve ventilation.
This adaptation made it possible to ensure an installation that was aesthetic, functional and durable .

The big day, step by step
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What would it look like 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.

Your own project, step by step
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.
