Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
A Discreet and Solid Installation for Better Distributed Comfort in a Kirkland Home
In Kirkland, our AirGreen team installed a MIDEA MIDEA28 dual-zone heat pump, consisting of two indoor units connected to a single outdoor unit. This type of configuration is particularly popular in West Island residences, where owners want to improve comfort in several rooms without multiplying outdoor equipment.
The photo shows a clean and structured installation: the MIDEA outdoor unit is fixed on robust wall brackets, above ground level, with a vertical drop carefully protected by a brown pipe cover matching the brick facade. This visual detail is not only aesthetic: it protects the refrigeration lines, wiring, and drain from weathering, impacts, and premature wear.
A Dual-Zone Heat Pump Designed for West Island Homes
Why a dual-zone configuration was ideal here
In this Kirkland residence, the client wanted to heat and cool two distinct spaces independently. A dual-zone heat pump allows for separate control of two rooms or living areas, while using a single outdoor unit. This is a very relevant solution when you want to improve comfort without undertaking major ductwork.
Unlike a central system, a multi-zone wall-mounted installation avoids several constraints related to existing homes: absence of ducts, finished ceilings, complex interior divisions, or different temperature needs depending on the floor and room orientation.
With the MIDEA MIDEA28, the client benefits from a system capable of offering good performance in both heating and cooling, while maintaining a discreet exterior appearance. This type of project is common in Montreal, Laval, Longueuil, on the North Shore and the South Shore, especially in homes where comfort varies greatly between the ground floor, upper floor, basement, or a rear extension.
An exterior installation that respects the facade
One of the most important aspects of this installation was visual integration. On a red brick facade with an exposed concrete foundation, every added element had to be carefully positioned. We installed the outdoor unit at a practical height, using adapted wall brackets to ensure good stability and adequate ventilation around the device.
The vertical brown pipe cover was chosen and installed to follow a straight line between the windows, which gives a clean and tidy result. This type of finish is essential in a residential HVAC installation: a high-performance heat pump must also be installed in a durable, safe, and visually acceptable manner.
Technical challenges encountered on site
As with many installations in the West Island, our team had to consider several elements:
- the position of the windows;
- the available space on the facade;
- the ideal height for the outdoor unit;
- the passage of refrigeration lines to the two indoor units;
- drainage management;
- protection of pipes against snow, ice, and temperature variations;
- the final appearance of the pipe cover.
In this specific case, the brick wall offered a good visual base, but required precise fastening so as not to weaken the masonry. Our technicians carefully selected the anchor points, ensuring that the wall brackets were perfectly aligned and strong enough to support the outdoor unit over time.
The importance of well-calculated outdoor positioning
A heat pump should never be installed haphazardly. The outdoor unit must have sufficient clearance to draw in and expel air correctly. Poor positioning can reduce performance, increase noise, complicate maintenance, and even accelerate compressor wear.
Here, the unit was placed on a clear section of the wall, at a height that better protects it against snow accumulation. This is particularly important in the Montreal region, where winters can quickly damage systems installed too close to the ground.
A MIDEA solution adapted to the client's real needs
The MIDEA brand is increasingly in demand for multi-zone residential projects, thanks to its excellent value for money, good performance, and availability. The MIDEA28 model is an interesting option for owners who want a reliable solution for two zones without opting for a more complex or oversized configuration.
In a house like this, the goal was not just to add air conditioning. The client also wanted an efficient heating solution for intermediate seasons and cold periods, while maintaining reasonable energy consumption.
Mistakes to avoid with a dual-zone heat pump
A dual-zone heat pump can offer excellent comfort, but only if it is properly sized and installed. Here are some common mistakes we see during inspections or replacements:
- choosing too low a capacity for both zones;
- installing indoor units in locations that block airflow;
- neglecting condensate drainage;
- leaving refrigeration lines insufficiently protected;
- placing the outdoor unit too close to the ground;
- using inadequate supports;
- prioritizing only price to the detriment of installation quality.
At AirGreen, we always evaluate the entire project before recommending a machine: area, orientation, insulation, interior divisions, client habits, architectural constraints, and access possibilities.
A clean installation facilitates HVAC maintenance
Installation quality also has a direct impact on HVAC maintenance. A well-positioned outdoor unit is easier to inspect, clean, and maintain. Well-protected connections reduce the risk of wear, vibration, or water infiltration. Well-installed indoor units facilitate filter cleaning and maintaining good airflow.
For a dual-zone system, we generally recommend regular maintenance to preserve performance, especially when both indoor units are frequently used for air conditioning in summer and heating in spring or autumn.
A final result that is both functional and aesthetic
The final result of this installation in Kirkland reflects what we aim for in every project: an efficient, durable, and well-integrated solution. The MIDEA outdoor unit is securely fixed, the lines are protected, the pipe cover is straight and harmonized with the facade, and the overall appearance remains discreet despite the presence of a dual-zone system.
This attention to detail makes a real difference. A misaligned or poorly protected installation can give a neglected impression and create long-term problems. Conversely, a well-planned installation inspires confidence and extends the system's lifespan.
AirGreen expertise applicable throughout Greater Montreal
Whether in Kirkland, Montreal, Laval, Longueuil, on the North Shore, or the South Shore, we adapt each HVAC installation to the building, budget, and actual needs of the client. A dual-zone heat pump is not a universal solution, but when chosen correctly, it can transform a home's comfort.
For this project, the MIDEA MIDEA28 represented an excellent balance between performance, flexibility, and visual integration. The installation also demonstrates the importance of entrusting this type of work to a team that understands both the technical requirements and the aesthetic constraints of an existing residence.
Practical advice for homeowners considering a similar installation
Before choosing a dual-zone heat pump, it is important to evaluate the following:
- the rooms to be heated and air-conditioned;
- the distance between the indoor units and the outdoor unit;
- the possible location of the pipe cover;
- the desired noise level;
- winter heating needs;
- available subsidies;
- insulation quality;
- window orientation;
- available space around the outdoor unit.
A thorough analysis avoids unpleasant surprises and ensures the selection of a system truly adapted to the home.
Subsidies and Eligibility
Depending on the exact model, the installed configuration, and the criteria in effect at the time of the project, some heat pumps may be eligible for financial aid programs such as LogisVert or other applicable Quebec subsidies. At AirGreen, we assist our clients in verifying eligible models, AHRI numbers, and the necessary conditions to maximize potential savings.
An installation that improves daily comfort
After installation, the client benefits from better temperature control in two areas of the house. This means fewer rooms that are too hot in summer, fewer cold zones during intermediate seasons, and more targeted energy use. Instead of heating or cooling the entire house uniformly, the dual-zone heat pump allows for adjusting comfort where it is truly needed.
This is precisely what makes this type of system so appealing for homes in Kirkland and the West Island: a modern, efficient, and discreet solution, without completely transforming the existing infrastructure.
