Installation of a Sharp Eco Inverter wall-mounted heat pump in Saint-Laurent
AirGreen installed a Sharp Eco Inverter wall-mounted heat pump in Saint-Laurent. An HVAC project optimized for comfort, energy savings, and access to subsidies in Greater Montreal.
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.
A comfort and energy efficiency project in a residential area of Saint-Laurent
At AirGreen , we recently completed the installation of a Sharp Eco Inverter wall-mounted heat pump in a residence in the Saint-Laurent district of Montreal . This intervention perfectly illustrates our expertise in HVAC installation in urban environments where every detail counts, both for energy efficiency and system sustainability.
In this project, our client was looking for a reliable and modern solution to ensure four-season comfort, while reducing energy consumption and taking advantage of subsidies available for high-performance heat pumps in Quebec.
Choosing the Sharp Eco Inverter heat pump
The Sharp Eco Inverter heat pump is a smart choice for Montreal homeowners. This line features:
-
Inverter technology allowing power to be continuously adapted according to actual needs.
-
Sharp's exclusive integrated Plasmacluster Ion system improves indoor air quality.
-
Reliable performance in heating and air conditioning, ideal for the climate of Montreal and the North and South Shores .
-
Compatibility with energy subsidy programs offered to residents of Montreal, Laval and Longueuil.
Technical details and custom installation
For this project, the outdoor condenser was carefully installed on treated wooden supports resting on a concrete slab, ensuring optimal stability and protection against humidity and water infiltration.
Some highlights of the installation:
-
Route of the refrigerant connections carefully covered and connected to a wall-mounted electrical box.
-
Gravity management of condensate , thus avoiding the addition of a pump and reducing maintenance costs.
-
A configuration designed for future accessibility in the event of HVAC maintenance.
-
Respect safety clearances around the condenser to ensure optimal ventilation and maximum unit performance.
The challenges and solutions provided
Installing a wall-mounted heat pump in Saint-Laurent requires adapting to the constraints of each building. In this specific case:
-
The concrete load-bearing wall presented a challenge for securing and routing pipes. Our technicians used a specialized drilling process with waterproofing treatment to prevent any water infiltration.
-
The proximity of the electrical panel made it possible to reduce the length of the wiring, thus optimizing the cost and efficiency of the installation.
-
In order to minimize the aesthetic impact, the conduits were discreetly positioned and protected by a harmonized white capping .
Immediate benefits for the customer
Upon startup, the customer noted:
-
Increased comfort with a uniform temperature throughout the service area.
-
Reduced noise thanks to inverter technology and compact condenser design.
-
Better indoor air quality , the Plasmacluster system helps eliminate pollutants and allergens.
-
Anticipated savings on energy bills, reinforced by access to subsidies available for the installation of efficient heat pumps in Greater Montreal.

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.
