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.
Discreet and efficient integration for lasting comfort
In a typical Villeray apartment, known for its high-ceilinged buildings and classic finishes, our team recently installed a Sharp wall-mounted air conditioner . This intervention was part of a project where the client was looking for an economical, quiet solution adapted to Montreal summers , without altering the interior aesthetics of his home.
A Sharp wall-mounted air conditioner: a choice of performance and reliability
For several years, the Sharp brand has established itself as a trusted alternative in the residential HVAC market in Montreal and the surrounding areas (Laval, Longueuil, North Shore and South Shore). Its reputation is based on reliable units with a minimalist design that offer excellent energy efficiency .
In this project, the model installed is a Sharp wall-mounted air conditioner from the compact residential series , designed for small spaces while ensuring good surface coverage.
-
Type : Wall-mounted air conditioner (single-zone mini-split)
-
Nominal power : suitable for a living room of approximately 450 to 600 sq. ft.
-
Technology : Inverter, allowing significant energy savings
-
Noise level : among the lowest in its category, ideal for continuous use
Specific challenges encountered in Villeray
The client's apartment presented several constraints:
-
High ceiling height – requiring strategic positioning of the unit to ensure even air distribution.
-
Proximity to a window – limiting the possibilities of drilling into the wall for refrigeration lines.
-
Preservation of interior aesthetics – the client wanted the installation to remain discreet , without any visible ducting that would break the visual balance of the room.
Our tailor-made technical solution
To meet these requirements, our AirGreen team has adopted a methodical approach:
-
Optimal positioning : the Sharp wall unit was installed at the top of the wall, between the window and the wall light, ensuring unobstructed air diffusion.
-
Careful drilling and discreet capping : we opted for a direct passage through the exterior wall with a white capping finish perfectly integrated with the color of the walls.
-
Gravity-fed condensate : The housing layout allowed us to install a gravity drain, avoiding the addition of a condensate pump and thus reducing future maintenance costs and risks.
-
Controlled working at height : particular attention was paid to safety and precision during assembly, given the proximity of the ceiling.
Results obtained
At the end of the project, the client immediately noticed:
-
Improved interior comfort , with a stable and uniform temperature in your living room.
-
Aesthetics preserved : the Sharp air conditioner blends perfectly into the decor without attracting attention.
-
Noise reduction : The unit's quiet operation allows it to be used day or night.
-
Optimized energy consumption , particularly appreciated in a neighborhood like Villeray where the electricity bill can vary greatly depending on the season.
Energy subsidies and savings
Although the installation involved a simple wall-mounted air conditioner and not a heat pump, we informed the client of the programs available in Greater Montreal for more efficient solutions, such as the Sharp ZU1 series wall-mounted heat pumps, which are eligible for LogisVert and Greener Homes subsidies. This awareness opens the door to a possible upgrade of their system in the coming years.

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.
