A discreet and efficient solution for a modern living space
In a bright condo in the Rosemont–La Petite-Patrie neighborhood, our technicians installed a Midea wall-mounted heat pump to provide occupants with consistent comfort throughout the year. This project perfectly illustrates the importance of integrating an efficient HVAC solution in an urban environment, where energy performance and space optimization play a crucial role.
Choosing a wall-mounted heat pump
The decision to install a Midea wall-mounted heat pump was motivated by several advantages:
-
Compactness and discreet design : the model fits harmoniously into the living room wall, without cluttering up the space.
-
9,000 BTU capacity : perfectly suited for an open room combining living room and reading area.
-
Inverter technology : allowing precise modulation of power to reduce energy consumption.
-
Cold climate performance : designed to operate efficiently even in the harsh Montreal winter.
Challenges encountered during installation
-
Pipe routing : it was necessary to cross a load-bearing wall while maintaining a clean and discreet finish.
-
Wall-mounted aesthetics : The unit was positioned centrally, above the sofa, requiring careful installation to avoid any visible misalignment.
Thanks to the experience of our technicians, the pipe passages were carefully concealed under a white capping that blends in with the color of the wall, ensuring an elegant finish.
Steps of the intervention
-
Site analysis : assessment of the surface area, room orientation and ideal route for refrigeration connections.
-
Inner head attachment : positioned high to maximize air diffusion.
-
Drilling and passing lines : precise work to minimize visual impact and preserve the integrity of the structure.
-
Electrical connection : secure connection, compliant with RBQ standards.
-
Calibration and testing : adjustment of temperature and airflow according to occupant preferences.
Results obtained
The system provides optimal comfort in all seasons, with quiet operation and even air distribution. Homeowners now benefit from:
-
of an energy-efficient system , reducing their electricity bills;
-
equipment eligible for the Hydro-Québec and LogisVert subsidy programs ;
-
of a successful aesthetic integration , which respects the minimalist ambiance of the condo;
-
a complete AirGreen service , including preventive maintenance and assistance when needed.
AirGreen expertise at the heart of each project
At AirGreen, we understand that every HVAC installation must be tailored not only to the size and characteristics of the space, but also to the occupants' lifestyle. In urban condos in Montreal, Laval, Longueuil, as well as on the North and South Shores, we pride ourselves on delivering precise, efficient, and durable installations.
Conclusion
This installation of a Midea wall-mounted heat pump in a condo in Rosemont–La Petite-Patrie demonstrates the importance of careful work and choosing equipment adapted to everyday needs. With AirGreen, residents of the greater Montreal area benefit from reliable, economical solutions designed for their long-term comfort.
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.
