A HVAC solution perfectly integrated into a Montreal residential setting
At AirGreen , we recently completed an exemplary installation of a Midea28 wall-mounted heat pump in a charming duplex in the Rosemont–La Petite-Patrie area of Montreal. This neighborhood, characterized by its two-story buildings bathed in light and its openings overlooking urban gardens, represents an ideal environment for this type of compact and efficient system.
The choice of the Midea28: efficiency and comfort at the heart of everyday life
The Midea28 is a new generation wall-mounted heat pump that uses the more environmentally friendly and efficient R-454B refrigerant . This model is designed to deliver optimal energy efficiency even in Montreal's harsh winters, with an efficient operating capacity down to -30°C .
Its main characteristics:
-
Available powers: 9,000 to 33,000 BTU
-
Energy efficiency (SEER/HSFP) above market average
-
Continuously modulated inverter compressor
-
Silent technology for remarkable acoustic comfort
-
Eligibility for Quebec grant programs , including Rénoclimat and Chauffez Vert
This model fits perfectly into typical residences in central Montreal, where spaces are often limited and aesthetic requirements are high.
An optimized installation despite limited space
In this project, the interior head was installed above a door frame , under an exposed beam. This strategic positioning allows for optimal air circulation , while preserving the aesthetics and functionality of the room.
The AirGreen team had to overcome several technical challenges :
-
Limited clearance height between beam and ceiling.
-
Discreet routing of refrigerant pipes through the load-bearing wall leading to the exterior.
-
Gravity management of condensate , without a pump, thanks to a carefully calculated slope.
Thanks to meticulous planning and the expertise of our certified technicians, we were able to integrate the system without compromising either the structure or the interior finish.
Technical details of the installation
System type: Single-zone wall-mounted heat pump
Brand: Midea
Model: Midea28 (R-454B)
Installed capacity: 12,000 BTU
Configuration: indoor unit above the door, outdoor unit on a wall bracket at the rear of the residence
Drainage: gravity towards the outside
Power supply: 240V dedicated circuit with 15A circuit breaker
Aesthetics: white duct covers match the walls for a simple and discreet look
Every step—from initial drilling to commissioning—was performed in compliance with CSA-C22.1 safety standards and manufacturer requirements . Vacuuming and leak testing confirmed optimal performance from the first start-up.
Why choose a wall-mounted heat pump for a Montreal duplex?
Typical residential buildings in Montreal, such as those in Rosemont–La Petite-Patrie , are ideally suited to wall-mounted heat pumps . The advantages are numerous:
-
Four-season comfort : efficient heating in winter and air conditioning in summer.
-
Energy savings of up to 30% compared to traditional electric heating.
-
Quick and minimally invasive installation , without existing ventilation ducts.
-
Grants available , significantly reducing the initial purchase cost.
The Midea28 stands out here as a balanced choice between performance, durability and price, while meeting the energy efficiency criteria of the Quebec market.
An installation by AirGreen: expertise and reliability
At AirGreen, each installation project is approached with rigor and precision . Our technicians are trained to analyze the building's configuration , evaluate structural constraints and propose the most efficient and aesthetic solution possible .
In this Rosemont residence, our intervention took place over a single day, from site preparation to full commissioning, with minimal disruption to the occupants . The client immediately noticed the difference: a consistent temperature, a virtually inaudible noise level and remarkable heating efficiency, even in cool weather.
A sustainable and ecological investment
Installing a Midea28 heat pump means investing in clean , energy-efficient technology. This model, which runs on R-454B refrigerant , is part of Quebec's energy transition and fully meets the residential sector's greenhouse gas reduction objectives.
Additionally, the manufacturer's warranty and annual maintenance performed by AirGreen ensure longevity and long-term peace of mind .
In conclusion
This Midea28 wall-mounted heat pump installation in Rosemont–La Petite-Patrie perfectly illustrates our expertise in custom HVAC solutions in Montreal. By adapting every detail to the specific characteristics of the home, AirGreen demonstrates once again that energy performance, aesthetics, and comfort can coexist harmoniously in Montreal homes.
