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.
A residential project combining comfort and aesthetics
At AirGreen , we know that a wall-mounted air conditioner must not only provide thermal comfort, but also blend harmoniously into the living environment. In Chomedey, in a residential area of Laval, we recently installed a Fujitsu Halcyon unit , suitable for a family looking for freshness, energy efficiency and discretion.
A strategic choice for the home
The Fujitsu Halcyon range is renowned for its reliability and energy efficiency, making it particularly attractive to residents of Greater Montreal. This installation is part of a desire to improve summer comfort while maintaining controlled energy bills thanks to inverter technology, which adjusts power according to actual needs.
The technical stages of installation
This installation involved several key points:
-
Indoor unit positioned high up , on a central wall of the corridor, ensuring even distribution of fresh air in the adjacent rooms.
-
Discreet drilling of the wall allowing direct connection with the external condenser already installed on the brick facade.
-
Gravity management of the condensate drain , limiting the risk of breakdown and reducing long-term maintenance requirements.
-
Preserved aesthetics : no visible conduit inside, the device fits perfectly into the interior decoration of the house.
Challenges encountered and solutions adopted
Installing a wall-mounted air conditioner in a hallway requires finding the ideal balance between air circulation and visual discretion . Our technicians carefully considered the orientation of the air vents to maximize comfort in the bedrooms and the main room. In addition, the high positioning frees up wall space while optimizing air circulation.
Everyday comfort
Homeowners now enjoy fast and even cooling . The Fujitsu Halcyon air conditioner operates at a very low noise level , making it an ideal solution for rest areas. Precise temperature control allows them to adjust comfort room by room, without wasting energy.
Savings and subsidies
Fujitsu Halcyon models meet the energy efficiency criteria recognized by Hydro-Québec and Transition Énergétique Québec , which opens the door to certain subsidies. This helps reduce the initial investment and improves long-term profitability.

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.
