Installation of a Sharp Eco Inverter wall-mounted heat pump in Ahuntsic-Cartierville
AirGreen installed a Sharp Eco Inverter wall-mounted heat pump in Ahuntsic-Cartierville. A high-performance, energy-efficient HVAC solution for optimal comfort in 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 sustainable heating and air conditioning solution adapted to Montreal winters
At AirGreen , we regularly meet with single-family homeowners in Ahuntsic-Cartierville who want to improve their comfort while reducing their energy bills. In this project, our team installed a Sharp Eco Inverter wall-mounted heat pump with Plasmacluster Ion technology, perfectly suited to the needs of a family living in a residential area of Montreal where winters are harsh and summers are increasingly hot.
Choosing a Sharp Eco Inverter Heat Pump
The Sharp brand is known for its integrated air purification technologies and optimized energy efficiency. The Eco Inverter series offers reliable heating capacity down to low winter temperatures, making it eligible for energy-saving grant programs in Quebec . Among its benefits:
-
Plasmacluster Ion Technology : Improves indoor air quality by neutralizing certain particles and pollutants.
-
Inverter Compressor : Automatically adjusts power to maintain a stable temperature while reducing electricity consumption.
-
Compact design : facilitates integration both outdoors and indoors, even in cramped residential environments.
Installation details
This installation was carried out on a typical red brick house in the area. We chose a wall-mounted mounting system , which allows the outdoor unit to be kept high up to protect it from snow and ice build-up. Condensate is drained by gravity, eliminating the need for an additional pump.
The refrigerant piping and electrical wiring were carefully concealed using discreet white capping , resistant to UV and winter conditions. The installation includes:
-
15 feet of standard piping between the indoor unit and the outdoor compressor.
-
15 feet of electrical wiring connecting the compressor to the main panel of the house.
-
A precisely made brick hole , ensuring complete insulation against air and moisture.
Challenges encountered and solutions provided
The installation took place in the middle of winter, which always presents a particular challenge for HVAC technicians: snow on the ground, sub-zero temperatures, and the risk of frozen condensation. To ensure equipment reliability:
-
We have carried out a secure clearance around the outdoor unit , ensuring optimal air circulation.
-
A solid galvanized steel bracket was fixed directly to the brick wall to prevent any sagging due to freeze-thaw.
-
A leak test and a complete performance test were carried out, confirming the system's efficiency even at low temperatures.
Comfort and savings for occupants
Thanks to this installation, occupants now benefit from:
-
4-season comfort : efficient heating down to -25°C and efficient air conditioning in summer.
-
A significant reduction in electricity costs , compared to old pure electric heating systems.
-
Improved air quality , a valuable asset for a family sensitive to allergies and urban pollution.

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.

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.
