Installation of a Sharp Eco Inverter wall-mounted heat pump in Villeray–Saint-Michel–Parc-Extension
Installation of a Sharp Eco Inverter wall-mounted heat pump in Villeray. AirGreen ensures four-season comfort, energy efficiency, and access to HVAC subsidies in Montreal and the surrounding area.

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.

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.
Successful technical integration in a Montreal brick duplex
In a typical duplex in the Villeray–Saint-Michel–Parc-Extension neighborhood, our team recently installed a Sharp Eco Inverter wall-mounted heat pump . The goal: to provide occupants with a high-performance HVAC system capable of ensuring comfort and energy savings throughout the year, while respecting the architecture of an old building with red brick walls.
A heat pump adapted to the needs of a Montreal family
The Sharp Eco Inverter is designed to meet Quebec's climate. Thanks to its inverter system, it automatically adjusts its power, reducing temperature fluctuations and peaks in power consumption. This energy efficiency is accompanied by greater comfort in both summer and winter. In addition, its integrated technology allows for better indoor air quality, a sought-after benefit in urban homes.
Technical challenges encountered
Each building in Greater Montreal has its own particularities, and this installation was no exception:
-
High-mounted on wall brackets : the condenser has been securely installed at a raised level to prevent snow accumulation and ensure optimal air circulation.
-
Passage of refrigerant and electrical connections : the conduits were carefully sheathed and protected by discreet white capping, ensuring both safety and aesthetic integration.
-
Dedicated power supply : a box has been added near the outdoor unit, facilitating maintenance and ensuring safe connection.
-
Drainage management : Precise positioning allowed gravity drainage of condensate, eliminating the need for an additional pump.
Immediate and lasting comfort
Since the start of service, the family has noticed several improvements:
-
Fast and even cooling of main rooms during hot days.
-
A reduction in electricity bill compared to using older portable air conditioners.
-
Sound tranquility thanks to the Sharp unit design, which significantly reduces operating noise.
-
Better space management since the outdoor unit does not rest on the ground and thus frees up the backyard.
Grants available for this type of installation
High-efficiency wall-mounted heat pumps like the Sharp Eco Inverter are eligible for provincial and federal grant programs, particularly for their ability to heat efficiently even in sub-zero temperatures. At AirGreen, we assist our clients in preparing and submitting grant applications to reduce initial investment costs.
AirGreen expertise serving Montreal neighborhoods
Throughout our installations in Montreal, Laval, Longueuil, the North Shore and the South Shore , we have developed expertise adapted to local constraints: century-old houses, brick plexes, renovated duplexes or even new constructions. Our commitment is to offer reliable and durable HVAC solutions , while respecting the architecture and unique needs of each home.
Conclusion: an installation optimized for four-season comfort
This installation of a Sharp Eco Inverter in Villeray–Saint-Michel–Parc-Extension illustrates the added value of our approach: building analysis, careful technical installation, and seamless integration. The result: a family now enjoys superior comfort, summer and winter, with controlled energy consumption and a sustainable system.
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.
