In Rosemont–La Petite-Patrie, more and more homeowners are looking for an efficient, quiet heating and cooling solution adapted to the realities of a typical Montreal flat-roofed building. It was precisely in this context that our AirGreen team stepped in to install a Midea wall-mounted heat pump on the roof of a residential duplex in the neighbourhood.
Thanks to careful installation on an elevated structure, this heat pump will now ensure 4-season comfort for the occupants, while protecting the roof and optimizing the performance of the equipment.
The context: a Montreal duplex and a flat gravel roof
The building is a residential apartment building, typical of Rosemont–La Petite-Patrie: urban facade, mature trees around, and a flat roof covered with gravel.
The client's needs were clear:
-
Efficiently heat and cool the living space, summer and winter.
-
Minimize noise for occupants and the neighborhood.
-
Protect the roof membrane and avoid any localized overloading.
-
Plan for a clean, uncluttered and easy-to-maintain installation.
We recommended a Midea wall-mounted heat pump , a recent high-performance range, perfectly suited to small and medium-sized homes in Greater Montreal.
Choosing the Midea wall-mounted heat pump
For this project, we opted for a Midea wall-mounted heat pump from the “Midea28” family , a series designed for Quebec winters, using a new generation refrigerant with a lower environmental impact.
Key benefits for the customer
-
Four-season performance : reliable heating even at very low outside temperatures, ideal for Montreal's extreme cold.
-
High energy efficiency : power modulation reduces consumption while maintaining stable comfort, without sudden temperature variations.
-
Quiet operation : both for the indoor unit and the outdoor unit, which is essential in a dense area like Rosemont–La Petite-Patrie.
-
Customized comfort : precise temperature control, night mode, efficient dehumidification in summer.
This type of device fits perfectly into an energy bill reduction strategy, particularly when it replaces or supplements a traditional electrical system.
A flat roof installation designed to last
The most visible element of this project is the Midea outdoor unit installed on the building's flat roof . On this type of building, the way the heat pump is installed makes all the difference between a standard installation and a professional one.
Elevated support structure
The outdoor unit is fixed to a raised metal support , itself installed on wooden beams resting on distribution blocks :
-
The height helps keep the machine above the accumulation of snow and ice.
-
The wooden beams act as an intermediary between the structure and the roof, distributing the load over a larger area.
-
The blocks under the beams reduce point pressure and help protect the roof membrane .
This type of assembly is particularly suited to Montreal flat roofs, where the aim is to avoid any perforation of the membrane as much as possible.
Roof protection and vibration management
We paid particular attention to:
-
Mechanical stability : the structure is perfectly leveled so that the compressor works without stress.
-
Vibration management : the use of appropriate supports limits the transmission of vibrations to the building structure, thus reducing the noise felt inside.
-
Respect for the membrane : no aggressive direct fixing into the roof; everything is designed to minimize the risk of long-term infiltration.
Optimized airflow and clearance
The Midea unit has sufficient clearance at the rear, front, and sides , which ensures:
-
Excellent air circulation around the condenser.
-
Optimized performance in both air conditioning and heating modes.
-
A reduction in the risk of excessive frosting or overheating.
These clearances are essential to comply with the manufacturer's recommendations and ensure the longevity of the heat pump.
Neat refrigeration and electrical connections
The refrigeration lines and power supply are routed in an orderly manner into the building:
-
The route was carefully planned to limit the length of the pipes, which improves the efficiency of the device.
-
Solid and clean fixings, to reduce the risk of friction, pinching or premature wear.
-
Watertight penetrations at roof level, in accordance with best practices in residential HVAC.
Indoor comfort and energy savings
Thanks to this Midea wall-mounted heat pump installed on the roof:
-
Occupants enjoy stable comfort all year round , with a consistent temperature and well-dehumidified air in summer.
-
Electricity consumption related to heating is reduced compared to electric baseboard heaters alone, resulting in significant annual savings.
-
The system offers a rapid response : the room cools down or heats up in a short time.
-
Quiet operation improves the quality of life, both inside and outside, in a dense neighbourhood like Rosemont–La Petite-Patrie.
For the owner, it is also an investment that increases the value of the building , offering modern comfort that is highly sought after on the rental market and for resale.
