A discreet and efficient DoubleZone installation in a typical residential context in Terrebonne
In Terrebonne, many homeowners are looking for a heating and air conditioning solution that can meet two needs at once: improving comfort in multiple rooms and limiting the visual impact of the outdoor installation. This AirGreen project perfectly illustrates this type of project: the installation of a GREE FREE MATCH R32 DoubleZone heat pump, with 2 wall-mounted units powered by a single outdoor unit.
Upon arrival, our team quickly realized that the project required a precise approach. The outdoor unit had to be installed under a balcony, against a concrete foundation, in a limited space, while respecting the necessary clearances for the machine's proper functioning. The chosen location protected the device, reduced its direct exposure to bad weather, and preserved the aesthetic of the back facade.
The project photo clearly shows the result: a GREE outdoor unit neatly installed on wall mounts, with refrigerant lines and wiring carefully routed to the indoor zones. In this type of configuration, every detail counts: mounting height, conduit path, drainage management, anchor strength, clearance in front of the fan, and accessibility for future HVAC maintenance.
Why a DoubleZone heat pump was the right choice for this property
A DoubleZone heat pump is particularly interesting when a building has two distinct comfort zones. In this project in Terrebonne, the goal was to provide a stable and personalized temperature in two different spaces, without multiplying outdoor units. A single outdoor unit can power two indoor units, which reduces clutter, simplifies visual integration, and improves usage flexibility.
The GREE FREE MATCH R32 system is designed to meet this type of need. It allows for independent zone management, meaning each indoor unit can be used according to the actual habits of the occupants. For example, a living area can be air-conditioned more in the evening, while a bedroom or office can be kept at a different temperature. This approach avoids overheating or over-air-conditioning unused rooms.
For homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore, this type of installation often represents an excellent compromise between performance, comfort, and operating cost. In Terrebonne, where winters can be harsh and summers very humid, a well-designed HVAC installation improves comfort throughout the year.
GREE FREE MATCH R32: a flexible solution for Quebec homes
The GREE FREE MATCH R32 range is appreciated for its versatility. It is well suited for multi-zone installations, particularly in houses, duplexes, condos, and small residential buildings where several rooms need to be heated and air-conditioned without resorting to a full central system.
The R32 refrigerant also represents a significant advantage. It is increasingly used in new generations of heat pumps due to its better thermodynamic performance and reduced environmental impact compared to some older refrigerants. For an owner looking for a modern and sustainable solution, this is an important factor to consider.
In this installation, the choice of a 2-zone – 2-head system allowed for efficient distribution of heating and cooling capacity. The outdoor unit coordinates the demand of the two indoor heads as needed, enabling modulating operation that is more stable and comfortable than a system that constantly starts and stops.
An outdoor installation under a balcony: the details that make the difference
One of the most important aspects of this project was the location of the outdoor unit. Installing a heat pump under a balcony can be advantageous, but only if the work is well planned. It is essential to ensure that air can circulate freely in front of the unit, that the unit remains accessible for maintenance, and that the refrigerant lines are properly protected.
In this case, our team installed the outdoor unit on wall mounts securely attached to the foundation. This method raises the unit above the ground, which is very useful in Quebec's climate. In winter, snow, ice, and fallen leaves can impair performance if the unit is placed too low. Wall mounting limits these risks and facilitates clearance around the unit.
The installation visible in the photo also demonstrates the importance of clean conduit routing. The refrigerant lines were routed upwards, following a logical path along the building, to reach the indoor units. This type of work requires experience, as a poor path can create problems with aesthetics, drainage, mechanical protection, or future access.
At AirGreen, we pay particular attention to these details, as they directly influence the system's durability. A high-performance heat pump loses some of its value if installed without precision. Conversely, a well-executed installation allows the equipment to operate in better conditions for several years.
Challenges encountered on site
Each building imposes its own constraints. On this project in Terrebonne, several elements had to be taken into account:
- the restricted space under the balcony;
- the presence of a concrete foundation;
- the proximity of windows and the back door;
- the need to maintain sufficient access to the outdoor unit;
- the routing of conduits to two distinct indoor zones;
- the protection of lines against weather and impacts;
- the management of wall unit drainage.
The space under the balcony required precise installation. An outdoor unit must breathe adequately. Even if it is compact, it must never be confined to a place that prevents air discharge or intake. Our technicians therefore positioned the unit to maintain functional clearance in front of the fan.
Another challenge concerned the finishing of the exterior route. On a brick facade, conduits must be installed carefully to avoid a visually heavy result. The goal is not just to connect the machine, but to do it cleanly, robustly, and consistently with the building's architecture. This attention is particularly important in residential areas of Terrebonne, Laval, Montreal, and Longueuil, where owners want a high-performance installation without compromising their property's appearance.
Installation of the two indoor units: targeted comfort and independent control
A DoubleZone heat pump requires more extensive planning than a simple single-zone wall system. It is necessary to determine where each indoor unit will be most effective, taking into account air circulation, room usage, heat sources, sun exposure, and wall layout.
In this project, the two units were chosen to meet two distinct needs. The goal was to avoid uncomfortable zones, temperature differences, and rooms that become too hot in summer or too cold in winter. A well-positioned wall unit can transform the comfort of a space, but poor placement can reduce air reach and create dead zones.
Our technicians always evaluate several factors before finalizing the position of an indoor unit:
- the distance from the outdoor unit;
- the possible path of the refrigerant lines;
- the available height on the wall;
- the orientation of the air jet;
- ease of access for filter cleaning;
- natural condensate drainage;
- visual impact in the room.
This step is essential for obtaining a durable and pleasant HVAC installation for daily use. A beautiful machine that is poorly positioned can become frustrating. A well-integrated machine becomes almost invisible in daily use, while truly improving comfort.
Performance, energy savings, and seasonal comfort
The GREE FREE MATCH R32 system is designed to offer modulating performance. In practice, this means that the unit adapts its power to the actual demand, rather than always operating at full capacity. This modulation helps reduce temperature variations, improve comfort, and limit energy consumption when demand is moderate.
In Terrebonne, as in several sectors of the North Shore, homeowners often seek a system capable of assisting with heating for much of the winter, while providing efficient air conditioning during humid heat periods. A well-sized heat pump often reduces the use of auxiliary heating systems during transitional seasons and better controls indoor temperature in summer.
Comfort is not limited to temperature. A wall-mounted heat pump also helps better manage indoor humidity during air conditioning. In homes where the air becomes heavy in July and August, this improvement is often felt very quickly. Occupants benefit from more stable, less humid air, and better comfort in the targeted rooms.
Grants and eligibility: a point to check before purchasing
For many customers, the question of grants is central. Programs like Hydro-Québec's LogisVert can represent significant financial assistance when an eligible appliance is installed according to the required criteria. Amounts and criteria may vary depending on the model, capacity, certification, and rules in force at the time of installation.
At AirGreen, we support our clients through this step by providing them with the necessary information on the installed machine, a detailed invoice, and useful documents to submit their application. It is important to choose an eligible appliance, but also to ensure that the installation is carried out by a qualified company. A high-performance heat pump must be installed correctly to achieve the best results, both in terms of comfort and administration.
For clients in Montreal, Laval, Longueuil, the North Shore, and the South Shore, our team can recommend models adapted to the desired performance criteria, while taking into account the budget, the building, and actual needs.
Mistakes to avoid during a DoubleZone installation
A multi-zone installation can be very advantageous, but certain mistakes frequently occur when the project is poorly planned.
The first mistake is to choose capacity solely based on the number of rooms. Two rooms of the same area can have very different needs depending on their orientation, insulation, ceiling height, windows, and daily use. This is why an on-site evaluation is often preferable.
The second mistake is neglecting the conduit path. On a 2-head system, the refrigerant lines must be routed logically and precisely. A path that is too long, poorly protected, or incorrectly sloped can affect aesthetics, drainage, or ease of maintenance.
The third mistake is placing the outdoor unit too close to the ground. In our climate, snow and ice can quickly become a problem. Wall mounting, as in this project in Terrebonne, is often an excellent solution when the structure allows it.
The fourth mistake is underestimating the importance of maintenance. A heat pump must be cleaned regularly. The filters of the indoor units must remain clean, and the outdoor unit must be cleared of leaves, snow, and debris. Good HVAC maintenance extends the equipment's lifespan and helps maintain its efficiency.
