Comfort, efficiency and elegance: a custom installation by AirGreen
At AirGreen , we believe that a successful HVAC installation must combine performance, discretion, and seamless integration into the living space. This is exactly what we achieved in this bright condo in Plateau-Mont-Royal , where our team installed a Midea28 wall-mounted heat pump , a new-generation R-454B model known for its exceptional performance down to −30°C .
A demanding urban environment, a suitable solution
The Plateau-Mont-Royal is a vibrant neighborhood characterized by modernized older buildings, narrow balconies, and high-ceilinged interiors. In this context, every HVAC installation must be designed to minimize clutter and maximize energy performance.
The Midea28 has established itself as the ideal choice: compact, quiet and energy-efficient, it perfectly meets the heating and cooling needs of a Montreal condo while respecting new environmental standards thanks to its R-454B refrigerant with low global warming potential.
Step 1: Technical analysis and installation planning
Before any installation, our certified technicians perform a detailed site assessment . In this project, the aim was to determine the best location for the wallhead and the optimal route for the refrigerant lines.
The chosen wall, adjacent to a large window, provided excellent air circulation and direct access to the balcony for connection to the outdoor compressor. We also considered the proximity of the electrical panel to ensure a safe and discreet power supply.
Step 2: Installing the interior head and crossing the wall
The Midea28 indoor head was installed approximately 20 cm from the ceiling, an ideal position for even air distribution. The wall holes were precisely drilled to allow gravity drainage of condensate, thus avoiding the need for an additional pump and reducing the risk of noise.
Our technicians then installed white capping to match the wall finish, ensuring a clean and harmonious visual effect, in perfect harmony with the minimalist style of the condo.
Step 3: Installation of the outdoor compressor and connections
On the balcony, the Midea28 outdoor unit was mounted on anti-vibration mounts , ensuring stability and quiet operation. The refrigerant connections were insulated according to the standards of the Quebec Building Code, then pressure-tested before the system was evacuated and fully commissioned.
This meticulous approach ensures perfect sealing and maximum performance, even during the bitter cold of Montreal's winter.
Remarkable energy efficiency
The Midea28 is one of the most efficient models in its category:
-
High Seasonal Energy Efficiency Ratio (SEER)
-
Efficient heating down to −30°C
-
Inverter technology for precise temperature control
-
R-454B refrigerant , more environmentally friendly than R-410A
Thanks to these features, this heat pump is eligible for provincial and federal grant programs , such as Rénoclimat and Chauffez vert , allowing our customers to significantly reduce their installation and operating costs.
