In this project in Rosemont–La Petite-Patrie, we replaced an old heating/cooling system with a new-generation Midea central heat pump . The client's objective was clear: to improve home comfort in both summer and winter, reduce their energy bills, and have reliable equipment to withstand Montreal winters.
Context of the home and needs
The residence is a typical Rosemont house, with a semi-basement and a wooden back deck. The client had an aging, inefficient, and noisy system. He was looking for:
-
Stable comfort throughout the house (ground floor and basement rooms).
-
A four-season solution, capable of providing good heating during extreme cold.
-
A clean, safe and discreet installation at the back of the house.
After analyzing the thermal load of the residence and the configuration of the premises, we recommended the installation of a Midea central heat pump , connected to an existing duct network, in order to benefit from a uniform distribution of air conditioning and heating.
Choosing the Midea central heat pump
The Midea brand is one of the manufacturers we regularly install in Greater Montreal. It is known for:
-
Its excellent energy performance, both in heating and cooling modes.
-
Its inverter compressor technology continuously modulates power to maintain a stable temperature.
-
Its compatibility with harsh winters, with good heating capacity at low temperatures.
In this project, we opted for a new generation Midea central heat pump with R-454B refrigerant , a more modern refrigerant that reduces environmental impact while maintaining very good energy efficiency.
Inside, the heat pump is connected to a central air handler that distributes air through the existing ductwork. Outside, the Midea condenser shown in the photo is the heart of the system: it removes heat in the summer and extracts it from the outside air in the winter to transfer it inside.
Installation details visible in the photo
Several technical elements are important for this installation in Rosemont–La Petite-Patrie:
1. Positioning of the outdoor condenser
The Midea outdoor unit is installed on sturdy wall brackets , above ground level and drainage stones. This choice allows for:
-
Protect it against the accumulation of snow and ice.
-
Improve water drainage around the foundation.
-
Facilitating airflow around the fan is essential for performance.
The free space behind and around the unit complies with the clearances recommended by the manufacturer, which ensures good air circulation, therefore better efficiency and a longer compressor life.
2. Protection of refrigeration connections
The refrigerant and drain pipes are fully protected by a rigid line-set cover mounted on the facade. This finish has several advantages:
-
Mechanical protection against shocks, weather and rodents.
-
Improved aesthetics: the refrigeration lines are not visible and blend into the house.
-
Facilitating possible future maintenance or replacement of the pipes.
3. Electricity management and safety
We can distinguish:
-
An electrical disconnect box in the immediate vicinity of the unit, as required by Quebec electrical standards.
-
A rigid conduit neatly fixed to the wall for the wiring, avoiding exposed wires and increasing the durability of the installation.
This allows a technician to quickly shut off the heat pump's power supply in case of maintenance or emergency, while complying with the Electrical Code requirements.
4. Respect for openings and windows
The unit is installed near a basement window , but far enough away to:
-
To prevent the airflow from disturbing the occupants.
-
Do not obstruct natural light.
-
Reduce the risk of vibrations transmitted to the structure.
The positioning has been carefully studied to offer an ideal compromise between performance, accessibility for maintenance and acoustic comfort.
Technical Challenges and AirGreen Solutions
In the case of this house in Rosemont–La Petite-Patrie, several challenges had to be addressed:
-
Limited space behind the terrace :
The presence of the wooden deck and support structure required a compact installation that didn't obstruct access to the basement. We worked with adjustable wall brackets and optimized unit orientation to maximize circulation space. -
Concrete foundation and surface drainage :
The ground covered with river stones ensures good drainage, but we had to avoid excessive vibration on the foundation. The supports are fitted with anti-vibration pads and the unit is perfectly level, which reduces noise and vibration. -
Route of the pipes to the indoor unit :
We chose a direct passage to the basement, behind the white formwork, in order to minimize the length of the refrigeration lines , which improves the performance of the system and reduces losses.
Results for the client
After commissioning and performance testing, the customer now benefits from:
-
Consistent comfort throughout the house, both in the basement and on the ground floor.
-
Efficient heating even during periods of extreme cold , thanks to the advanced technology of the Midea central heat pump.
-
A reduction in energy bills compared to the old system, thanks to the inverter compressor and high seasonal efficiency.
-
A discreet, clean and easily accessible installation for maintenance, which respects the architecture of the backyard.
System maintenance and longevity
As with any central heat pump, we recommend:
-
A professional annual service , including checking the refrigerant level, cleaning the outdoor coil, checking the electrical connections and the condensation drain.
-
Regular cleaning of the indoor air manager filters to maintain good airflow and optimal air quality.
With proper maintenance, a Midea central heat pump can provide many years of reliable and economical service.
