An installation that combines interior comfort and energy performance
At AirGreen , every wall-mounted heat pump installation is an opportunity to combine technical expertise with lasting comfort. In Rosemont–La Petite-Patrie, we recently installed a Sharp wall-mounted heat pump , a high-performance solution for optimizing the heating and cooling of a Montreal home.
The Sharp heat pump: a reliable choice
Sharp heat pumps are designed to meet the needs of families seeking efficiency and comfort. They offer:
-
Inverter technology , which modulates the compressor power according to actual demand, thus reducing energy consumption.
-
Stable heating capacity even in winter , ideal for the climate of Greater Montreal.
-
A discreet design that blends harmoniously into living spaces.
-
Increased longevity , thanks to high-quality components.
The particularities of the installation in Rosemont
The indoor unit was installed high on a wall, in a strategic corner to allow for even air distribution throughout the main room. Here are the technical details of this project:
-
Optimized installation height , ensuring efficient air circulation without disturbing existing furnishings or wall lighting.
-
Discreet routing of refrigerant pipes , passing through the wall to the outside and protected by matching white capping.
-
Precise and adjusted connections to minimize piping length and ensure optimal performance.
-
Compliance with electrical standards with secure wiring to the distribution panel.
Technical challenges and solutions
In this home, the main constraint was the integration of the interior head near an existing wall light. Our technicians:
-
Planned the exact height to avoid any interference between the lighting and the air outlet.
-
Used precision tools to ensure clean drilling of the wall and perfect alignment with the outdoor unit.
Immediate benefits for occupants
As soon as it was put into service, the owners were able to observe:
-
A reduction in temperature variations , the heat pump automatically adjusting its power.
-
Quiet operation , allowing increased comfort in the main room.
-
Reduced energy consumption , a guarantee of savings on electricity bills.
AirGreen: comprehensive support
Beyond installation, we support our customers in:
-
The choice of the BTU power best suited to the configuration of their accommodation.
-
Apply for provincial and federal grants available for this type of energy-efficient equipment.
-
Regular HVAC maintenance service , ensuring the proper functioning of the heat pump over the long term.
Thanks to this installation, the Rosemont family now benefits from four-season comfort , supported by AirGreen expertise and equipment renowned for its reliability.
The job tools
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.
How the job unfolds
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 we check on a job like this one
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.
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.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
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.
The right pages, at the right time
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.
