In this project in Rosemont–La Petite-Patrie , we assisted the owners of a red brick duplex who wanted to improve their comfort year-round. Their goal: to replace a noisy and inefficient window air conditioner with a Midea wall-mounted heat pump , capable of providing both summer cooling and economical heating during the shoulder seasons.
Context of the house in Rosemont
The house is typical of the neighborhood: red brick facade, cement-rendered lower walls, and a small landscaped area with rockeries in front. The owners were looking for a solution that would:
-
It blends discreetly into the architecture;
-
Reduces the electricity bill;
-
Provides stable comfort in the main living area;
-
Remains reliable in the face of harsh Montreal winters .
After analyzing the heat load and room configuration, we recommended the installation of a Midea28 (R-454B) wall-mounted heat pump of approximately 12,000 BTU , perfectly suited to a duplex ground floor with an open living area.
The solution: Midea28 wall-mounted heat pump
The Midea28 is a next-generation wall-mounted heat pump that uses R-454B refrigerant and is designed to operate down to approximately -30°C . It offers:
-
High-efficiency inverter technology, which continuously modulates the power;
-
Excellent performance in both air conditioning and heating;
-
Very low noise level, both indoors and outdoors;
-
High energy efficiency, ideal for reducing annual consumption.
Inside, the Midea wall-mounted unit has been strategically positioned to cover the entire living area: living room, dining room, and kitchen. This ensures a uniform temperature without unpleasant drafts, while maximizing energy savings.
Outdoor unit installation details
The photo shows the Midea outdoor unit installed on the side wall of the house:
-
Mounting on galvanized steel wall brackets : the unit is securely fixed to the wall, above ground level and the rockery. This configuration protects the heat pump from snow, water, and debris, while also facilitating snow removal and winter maintenance.
-
Optimized clearance : The unit is installed away from the floor and wall to ensure optimal airflow around the condenser. This improves efficiency and extends the equipment's lifespan.
-
Drainage management : the condensation drain is oriented to avoid water accumulation near the foundation or in rockeries.
-
Preservation of the landscaping : the rockery and plants on the facade were protected during installation, then neatly replaced.
The refrigeration pipes and electrical cable are discreetly routed through the wall, insulated and covered according to best practices to ensure both aesthetics and protection against the elements.
Four-season performance and comfort
With this Midea28 wall-mounted heat pump , Rosemont homeowners now enjoy significantly greater comfort:
-
In summer : efficient and quiet air conditioning, even during Montreal's frequent heat waves. The temperature stabilizes quickly and humidity is better controlled, improving the feeling of coolness.
-
In mid-season : economical heating, ideal in spring and autumn to avoid starting the main system or multiplying auxiliary radiators.
-
In winter : the Midea28 provides efficient heating down to very low temperatures, reducing dependence on electric baseboard heaters and allowing real savings on the Hydro-Québec bill .
Inverter technology automatically adjusts the power according to actual needs, resulting in:
-
Fewer on/off cycles;
-
Optimized electricity consumption;
-
Smoother and more durable operation for the compressor.
A compliant and safe installation
Our certified teams installed this Midea heat pump in accordance with the manufacturer's standards and the requirements of the Code:
-
Vacuuming, leak testing and refrigeration circuit check;
-
Checking the electrical wiring, grounding and dedicated circuit breaker;
-
Complete commissioning with temperature and pressure measurements;
-
Detailed explanation of how to use the remote control and the different modes (cold, hot, dehumidification, auto).
We also advised the owners on basic maintenance : regular cleaning of indoor filters, clearing of space around the outdoor unit, visual inspection before and after winter, and the importance of periodic professional maintenance.
