Installation of a Midea wall-mounted heat pump in Ville-Marie (Montreal)
Discover the installation of a Midea wall-mounted heat pump in Ville-Marie by AirGreen. An ideal solution for year-round comfort in a condo in downtown Montreal.
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.
In this project located in the heart of Ville-Marie , our AirGreen team completed the installation of aMidea wall-mounted heat pump , a particularly suitable choice for an urban condo exposed to Montreal's demanding climate. This type of environment—flat roof, limited access, high urban density—requires rigorous planning and flawless execution, both technically and aesthetically.
An HVAC system perfectly suited to a downtown condo
The Ville-Marie area is characterized by a high concentration of condominium buildings, often featuring flat concrete roofs, mineral facades, and limited mechanical space. In this context, the wall-mounted heat pump (mini-split) stands out as an efficient, quiet, and unobtrusive solution.
For this project, we opted for a Midea wall-mounted heat pump , a manufacturer renowned for the reliability of its systems and their excellent performance in cold climates. The chosen model, consistent with the existing installation, is a Midea28 , a unit designed to meet the realities of Quebec winters.
Why the Midea28 wall-mounted heat pump is an excellent choice in Ville-Marie
The Midea28 stands out due to several key features that make it ideal for a Montreal condo:
-
Heating performance down to -30°C , essential for coping with harsh winters
-
Inverter technology , ensuring precise power modulation and optimized energy consumption.
-
Silent operation , a crucial criterion in dense urban environments
-
Compact format , facilitating integration on a roof or restricted outdoor structure.
-
Excellent energy efficiency , both in summer air conditioning and winter heating.
This type of heat pump makes it possible to advantageously replace less efficient electric systems, while improving indoor comfort all year round.
Installation details observed and technical constraints
Several prominent technical elements in the photos confirm that the installation was designed to last:
-
Outdoor unit installed on a raised structure , suitable for flat roofs and preventing the accumulation of snow and ice.
-
Robust support with anti-vibration isolation , reducing noise transmission and protecting the roof membrane
-
Adequate clearance around the condenser is essential for optimal airflow.
-
Neat routing of refrigeration lines , protected against the elements and compliant with current standards
-
Winter installation , demonstrating our ability to intervene effectively even in cold conditions
In Ville-Marie, each installation also requires consideration of condominium regulations, rooftop access, and visual discretion. Our team always ensures that the system integration respects the building's aesthetics.

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.

And 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.
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.
