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.
An installation suitable for a residential stairwell
At AirGreen , we often encounter projects where space optimization and comfort must go hand in hand. This is exactly what we achieved in a residence in Laval-des-Rapides , where the installation of a Sharp ECO Inverter series wall-mounted heat pump significantly improved occupant comfort. Positioned in an interior stairwell , this unit provides optimal air distribution between the different levels of the house.
Why choose a Sharp ECO Inverter wall-mounted heat pump?
The Sharp ECO Inverter Series is designed for homeowners seeking a balance between energy performance , reliability and quiet sound .
Some highlights of this model:
-
Inverter technology to automatically adjust compressor speed and reduce energy consumption.
-
Heating and air conditioning function adapted to the climate of Greater Montreal.
-
Modern and compact design, easy to integrate even in tight spaces such as a stairwell.
-
Reduced noise level, ideal for passage areas or living rooms.
Steps of installation carried out by AirGreen
The installation in this house in Laval-des-Rapides involved several technical challenges that our team was able to master:
-
Strategic positioning of the inner head
Placed high up, the wall-mounted heat pump efficiently serves the upper and lower floors thanks to the natural circulation of air in the stairwell. -
Drilling and connection
We made a precise outward drilling to connect the inner head to the condenser. The refrigeration pipes and electrical cables were protected by discreet capping, ensuring safety and aesthetics. -
Condensate management
Gravity drainage was preferred, taking advantage of the height available in the staircase to ensure smooth evacuation without the need for an additional pump. -
Securing the construction site
The stair work area required the use of a professional ladder and safety devices to ensure a reliable and risk-free installation.
The constraints encountered and our solutions
-
Restricted access and significant height : Working in a stairwell requires specific logistics. We've secured the area with suitable equipment and planned each step to minimize risks.
-
Uniform air distribution : To avoid areas that are too cold or too hot, we adjusted the orientation of the shutters and carried out air circulation tests after commissioning.
Immediate benefits for occupants
From the moment it was activated, the Sharp ECO Inverter heat pump demonstrated its full effectiveness:
-
A uniform freshness spread throughout the living spaces.
-
The quiet operation was highlighted by the occupants.
-
The system's energy efficiency will reduce electricity costs year-round, for air conditioning in the summer and for supplementary heating in the winter.

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.
