A clean and efficient installation carried out in the middle of winter on the South Shore
At AirGreen , we pride ourselves on helping South Shore residents enjoy optimal comfort year-round , even when the temperature dips below zero. This service call in Sainte-Julie involved the installation of a Midea wall-mounted heat pump , a solution known for its remarkable energy efficiency and reliability in cold climates.
The context of the project
Our client had just moved into a new condominium. The building had limited outdoor space: a north-facing concrete balcony , exposed to wind and snow. The challenge was to install a compact outdoor unit while complying with clearance and safety standards.
The goal: to provide a four-season heating and air conditioning system without altering the aesthetics of the building or disturbing neighbors.
Technical analysis and site preparation
First of all, our technicians carried out:
-
An electrical assessment to ensure the capacity of the existing circuit.
-
A check of the minimum distances required for ventilation and defrosting.
-
Planning the passage of refrigerant pipes through the concrete wall, minimizing breakthroughs and ensuring perfect insulation.
A galvanized aluminum wall structure was attached to elevate the compressor—an essential choice to prevent ice buildup on the floor and facilitate drainage.
Midea heat pump installation
The Midea outdoor unit chosen belonged to the Hyper Heat series , designed to maintain stable heating down to -25°C. Our technicians carried out the following steps:
-
Fixing the bracket and precise leveling to prevent any future vibration.
-
Installation of electrical wiring and installation of a protected junction box in accordance with the Canadian Electrical Code.
-
Passage of insulated refrigeration ducts in a clean and waterproof wall cladding, ensuring aesthetic integration.
-
Internal connection to the already installed wall unit, followed by rigorous vacuuming of the circuit using a professional pump.
-
Nitrogen pressure test to confirm the system is perfectly sealed.
-
Refrigerant recharge and progressive start-up under instrumented monitoring.
Checks and final performance
Once started, the Midea heat pump demonstrated its full effectiveness:
-
Stable and high blowing temperature despite the ambient -10°C.
-
No perceptible vibration thanks to the precise balancing of the support.
-
Very low noise levels, barely audible from the neighboring balcony.
-
Reduced electricity consumption compared to traditional additional heating.
We also checked the automatic defrost , essential during Quebec winters. The unit responded exactly as expected, maintaining performance without interruption.
AirGreen Recommendations
At AirGreen , each installation is carried out according to the manufacturer's standards and the climatic realities of Greater Montreal . For this type of configuration in a co-ownership, we recommend:
-
An annual check of the refrigerant level and compressor condition.
-
Cleaning the outdoor coil before winter.
-
Maintaining a minimum clearance of 30 cm around the unit for optimal airflow.
We also trained the customer on good maintenance practices, including using the defrost mode and periodically cleaning the interior filter.
Result: comfort and aesthetics combined
Thanks to this intervention, the customer now benefits from a high-performance, quiet and durable Midea system , capable of ensuring four-season comfort while reducing its energy consumption.
The discreet integration of the unit on the balcony, combined with a clean and professional finish, perfectly reflects the AirGreen philosophy: efficiency, precision and respect for the residential environment.
