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 modern HVAC solution adapted to Montreal realities
At AirGreen , we know that a successful wall-mounted heat pump installation isn't just about choosing the right unit: it's also about seamless integration into the home, optimal ductwork, and impeccable finishing. That's exactly what we achieved in a brick duplex in the Rosemont–La Petite-Patrie area, where we installed a Sharp Eco Inverter equipped with Plasmacluster Ion technology . This combination provides reliable comfort, improved indoor air quality, and significant energy efficiency for Greater Montreal's winters and summers.
Why choose the Sharp Eco Inverter?
The Sharp Eco Inverter range stands out for its balance between performance and compactness. The model chosen by our client offers several advantages:
-
Inverter technology : power modulation to maintain a stable temperature while reducing electricity consumption.
-
Ion Plasmacluster : a Sharp-exclusive system that improves air quality by neutralizing allergens, bacteria and odors.
-
High energy efficiency : eligible for Quebec energy efficiency grant programs .
-
Quiet operation : perfect for a family home where sound comfort is as important as thermal comfort.
Installation challenges and solutions
Architectural context
The house, typical of Rosemont, has a solid brick facade with basement windows. The limited exterior space required careful planning so as not to encroach on access or disrupt the aesthetics of the courtyard.
Heavy Duty Wall Mounts
We mounted the outdoor unit on galvanized wall brackets capable of supporting the weight of the compressor while providing sufficient clearance from the ground. This configuration protects the equipment from snow accumulation and facilitates maintenance.
Capping and finishing
The refrigerant and electrical pipes were grouped together in a brown capping that discreetly blends in with the existing downspout. This aesthetic choice allows for a clean integration, without visible cables, and reinforces the insulation of the lines.
Drainage management
Thanks to the facade layout and the height of the installation, we were able to provide gravity drainage of the condensate, thus avoiding the need for an additional pump. This solution simplifies maintenance and reduces the risk of breakdowns.
Four-season comfort
With a capacity calibrated to the needs of the home, this Sharp wall-mounted heat pump ensures:
-
Reliable heating down to -25°C , perfect for tackling winter cold snaps.
-
Effective air conditioning in summer , even during Montreal heat waves.
-
Significant energy savings compared to traditional electrical systems.
-
Improved indoor air quality thanks to the Plasmacluster, a particularly popular feature for families.
Final result
After several hours of methodical work, our team delivered a discreet, secure, and optimized installation. The client now benefits from a modern HVAC system that combines thermal comfort, air quality, and energy savings.

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.
