Installation of a Sharp Eco Inverter wall-mounted heat pump in Rosemont–La Petite-Patrie
Installation of a Sharp Eco Inverter wall-mounted heat pump in Rosemont. AirGreen ensures optimal comfort and superior energy efficiency for Montreal and the surrounding area.

In summer, the outdoor unit rejects the house's heat outside.

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 neat installation in the heart of a Montreal brick duplex
At AirGreen , we are regularly called upon to work in typical Montreal buildings where the red brick facade imposes specific constraints for the installation of a wall-mounted heat pump . This project, carried out in the Rosemont–La Petite-Patrie sector, involved the installation of a Sharp Eco Inverter with Plasmacluster Ion technology, a high-performance and reliable solution for improving the comfort of a duplex.
The outdoor unit was installed directly onto a brick wall, at an ideal height to ensure good airflow and avoid the inconvenience of winter snow accumulations. The use of sturdy wall brackets ensured perfect stability, while freeing up floor space.
Features of the Sharp Eco Inverter Heat Pump
The Sharp brand, known worldwide for its electronic and household appliance solutions, also develops reliable HVAC equipment. This Eco Inverter model is distinguished by:
-
Inverter technology that continuously adjusts the compressor speed to optimize electricity consumption.
-
The exclusive Plasmacluster Ion system, designed to improve air quality by reducing harmful particles and allergens.
-
Superior energy efficiency, allowing homeowners to reduce their electricity bills while enjoying constant thermal comfort.
-
Reliable heating capacity even during Montreal's harsh winters, an essential point for families in the region.
The Challenges of Moving into a Montreal Duplex
Installing a wall-mounted heat pump in Montreal in an old brick building always requires careful planning:
-
Drilling through the walls : the crossing had to be done cleanly so as not to damage the masonry and to ensure good watertightness.
-
Management of refrigeration and electrical lines : discreet capping, harmonized with the facade, was used to protect the conduits and preserve the exterior aesthetics.
-
Strategic positioning : the condenser was positioned to comply with regulatory clearances, avoid any noise nuisance for neighbors and facilitate future maintenance.
-
Condensate drainage : thanks to a gravity installation, drainage occurs naturally, which reduces maintenance and extends the lifespan of the equipment.
Optimal results for four-season comfort
Thanks to this installation, the owner now benefits from:
-
Efficient heating in winter , capable of maintaining a stable temperature even when the mercury drops very low.
-
An efficient wall-mounted air conditioner in summer , guaranteeing immediate comfort during the frequent heat waves in Montreal.
-
Better indoor air quality thanks to the Plasmacluster Ion system, a significant advantage for families sensitive to allergies.

How it goes, from the first call to the end
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.

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.
- 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.
