Generic diagram: central heat pump, indoor module and ducts

In summer, the outdoor unit rejects the house's heat outside.

Generic illustration of this type of installation, not a survey of this job site. Tap a number.

  1. It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.

  2. The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.

  3. A shut-off switch near the outdoor unit isolates it safely for service.

  4. Sitting on the indoor module, it moves heat between the house air and the refrigerant.

  5. Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.

  6. Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.

  7. It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.

  8. It runs the heat pump and the backup heat. It must be compatible with the installed system.

A GREE Central Installation Designed for Daily Comfort in Kirkland

In Kirkland, in Montreal's West Island, many single-family homes already have central heating and ventilation infrastructure: existing ducts, electric or gas furnace, main return air, adapted electrical supply, technical basement, mechanical room, or service space. In this type of property, choosing a central heat pump often becomes a particularly logical solution, as it improves comfort throughout the house without multiplying wall-mounted units in individual rooms.

For this installation, our AirGreen team proceeded with the installation of a GREE central heat pump with an outdoor unit mounted on wall brackets, directly against the residence's foundation. The photo shows a clean, compact, and well-integrated job: the outdoor unit is secured above ground level, the brackets are firmly anchored, the clearance in front of the fan is respected, and the AirGreen identification confirms an installation carried out according to our finishing standards.

This type of project is representative of the requests we regularly receive in Montreal, Laval, Longueuil, on the North Shore and the South Shore: homeowners want to modernize their HVAC system without compromising external aesthetics, while benefiting from more efficient heating in winter and more stable central air conditioning in summer.

In this specific case in Kirkland, the client was looking for a solution capable of better distributing temperature throughout the house, reducing reliance on traditional electric heating during milder periods, and providing uniform air conditioning during heatwaves. The GREE central heat pump perfectly met these objectives, provided that the installation was precisely planned.

A project where installation quality makes all the difference

A central HVAC installation is never limited to placing an outdoor unit and connecting two refrigerant lines. Every detail influences the system's actual performance: unit location, bracket level, line protection, drainage, clearances, service access, electrical supply, compatibility with the indoor system, thermostatic control, and final start-up.

At this Kirkland property, our team paid particular attention to the outdoor unit's location. The chosen wall allowed for a discreet installation, close to the existing mechanicals, while maintaining sufficient clearance for air circulation. The GREE unit is positioned above the foundation, which helps protect it against snow accumulation, water splashes, fallen leaves, and small debris that can end up on the ground.

This installation choice is particularly relevant in the Montreal region, where winters can bring significant snow accumulations, freeze-thaw cycles, and freezing rain episodes. A poorly positioned central heat pump can lose efficiency, become more difficult to maintain, or be exposed to unnecessary stresses. Here, the wall-mounted installation offers a robust, practical, and durable solution.

Why GREE is a serious choice for a central heat pump

GREE is a recognized brand in the field of heat pump and air conditioning systems, notably thanks to its Inverter technologies, modulating compressors, and equipment designed to meet modern residential needs. For a Kirkland home, where comfort must remain stable from one floor to another, Inverter technology represents a significant advantage.

Unlike a traditional system that often operates with more distinct on-off cycles, a GREE central heat pump with Inverter technology can adjust its capacity according to actual demand. This modulation helps maintain a more constant temperature, reduce comfort variations, and improve energy efficiency when outdoor conditions are moderate.

The concrete benefits for the homeowner are numerous:

  • a more homogeneous temperature in rooms served by ducts;
  • smoother, less abrupt central air conditioning;
  • effective heating for a large part of the cold season;
  • a potential reduction in energy consumption depending on usage and the old system;
  • quieter operation than a poorly sized conventional equipment;
  • discreet integration with the existing air distribution system.

For AirGreen, the choice of model is never left to chance. Before recommending a heat pump, we analyze the house's configuration, insulation, duct type, client habits, comfort expectations, available electrical capacity, and installation constraints. A high-performance machine delivers its best results only when it is well-selected and correctly installed.

A clean, stable, and accessible outdoor installation

The photo of this installation in Kirkland highlights several important elements. The GREE outdoor unit is installed on well-aligned metal wall brackets, allowing the unit to remain clear of the ground. This type of support is often recommended when ground space is limited or when it is desired to protect the equipment from seasonal accumulations.

The unit is installed against a vinyl exterior siding, above a concrete foundation. This configuration requires great precision, as the fasteners must be solid, well-positioned, and capable of supporting normal operating vibrations. Our technicians take care to install the unit stably to limit noise transmission and ensure good system longevity.

Access to the service panel also remains essential. In this installation, the space around the unit allows for HVAC maintenance, seasonal checks, outdoor coil cleaning, and future diagnostics. An installation that is too tight or poorly oriented complicates interventions and can increase long-term maintenance costs.

At AirGreen, we always insist on this point: a beautiful installation is important, but an accessible installation is just as important. The client does not always see these details at first glance, but they make a big difference after several years of use.

The importance of positioning for Kirkland homes

Kirkland has many homes with side yards, landscaped backyards, setbacks, paved driveways, and outdoor spaces used daily. The positioning of a central heat pump must therefore consider indoor comfort, but also the outdoor use of the property.

In this project, the chosen location helped limit the visual impact of the equipment while maintaining a practical distance from mechanical connections. We also considered the airflow around the unit. An outdoor fan must be able to discharge air without obstruction; otherwise, the system can lose efficiency, especially on very hot days or during prolonged heating periods.

A common mistake is to place an outdoor unit too close to an obstacle: fence, dense hedge, shed, parallel wall, storage bin, or enclosed patio. Even if the installation may seem clean initially, performance can be affected if air circulation is poor. That's why our team always checks recommended clearances and adapts the solution to the actual terrain.

Integration with the existing central system

A central heat pump generally works with an indoor system connected to the house's duct network. This can involve an indoor coil, an air handling unit, an existing furnace, or a hybrid configuration depending on the building. The goal is to circulate heated or air-conditioned air through the different zones of the house.

In an installation like this one in Kirkland, a prior analysis of the indoor system is essential. Ducts that are too small, poorly balanced, or insufficiently insulated can limit the performance of excellent equipment. A house can have a new, high-performing machine, but if the air distribution is not adequate, some rooms will remain too hot or too cold.

Our technicians therefore check several elements before and during installation:

  • the compatibility of the outdoor unit with the indoor system;
  • the general condition of the ducts;
  • ventilation capacity;
  • thermostat location;
  • return air;
  • electrical requirements;
  • refrigerant line path;
  • connection protection;
  • start-up and operating parameters.

This approach avoids unpleasant surprises and allows the client to fully benefit from their investment.

A solution adapted to the climate of Montreal and the West Island

Kirkland's climate is that of Greater Montreal: humid summers, cold winters, unstable springs, and variable autumns. A good HVAC system must therefore be able to handle several realities, sometimes within the same week. A well-sized GREE central heat pump can provide very significant comfort, especially in homes where temperature differences between rooms are to be avoided.

For air conditioning, the advantage of a central system is uniform distribution. Cool air circulates through the ducts and reaches the main rooms, bedrooms, corridors, and living spaces according to the network configuration. For families who want to avoid visible units in each room, this is a very interesting option.

For heating, the heat pump can cover a significant portion of needs depending on outdoor temperatures, insulation, and system configuration. During periods of moderate cold, it can offer higher efficiency than several forms of direct electric heating. During more intense cold spells, a backup system can take over or supplement demand, depending on the overall design.

Subsidies and energy efficiency: what homeowners need to check

Homeowners in Kirkland, like those in Montreal, Laval, Longueuil, on the North Shore, and on the South Shore, are often interested in available subsidies for installing a heat pump. Some models may be eligible for financial assistance programs, especially when the equipment meets the required criteria for energy performance.

It is important to check the exact eligibility of the installed model at the time of the project, as programs, amounts, and requirements can be updated. At AirGreen, we help our clients understand the usual steps: choosing eligible equipment when possible, keeping necessary documents, obtaining a detailed invoice, and submitting the application according to the rules of the applicable program.

A mistake to avoid is choosing a system solely based on a subsidy. The subsidy is a financial advantage, but it does not replace a good HVAC analysis. The right equipment must first match the house, the duct network, comfort expectations, and technical constraints. Then, financial aid can improve the return on investment.

Technical challenges encountered during this type of installation

Even when the outdoor installation seems simple, a central heat pump requires rigorous coordination. In Kirkland, properties are often well-maintained, with neatly arranged outdoor spaces. Therefore, it is necessary to work cleanly, protect surfaces, limit visual impact, and respect the physical constraints of the house.

Among the frequent challenges in this type of project, we find:

  • selecting the best exterior wall for the unit;
  • managing the passage of refrigerant lines;
  • protecting the exterior siding;
  • respecting clearances around the unit;
  • coordination with the electrical supply;
  • vibration reduction;
  • perfect leveling of the unit;
  • checking drainage and defrost cycles;
  • future access for maintenance.

In this project, the wall-mounted installation allowed the unit to remain well-cleared, while maintaining a compact integration. The final result is clean, professional, and functional, exactly what we aim for in a system designed to operate for many seasons.

What the client wanted to achieve

The owner primarily wanted to improve the overall comfort of the house without adding multiple visible appliances indoors. A central heat pump was therefore a natural option. The central system allows for maintaining a clean interior aesthetic while enjoying comfort distributed throughout the residence.

The client also wanted reliable equipment, capable of meeting summer air conditioning needs and supporting heating during colder seasons. Like many Kirkland homeowners, they were looking for a modern, efficient, and well-installed solution, with professional support from start to finish.

Our role was to transform these expectations into a concrete solution: equipment recommendation, technical planning, outdoor installation, connections, checks, start-up, and explanation of operation.

Practical tips before installing a central heat pump

For homeowners considering a similar installation in Kirkland or elsewhere in Greater Montreal, a few tips can help avoid costly mistakes.

First, the house should be evaluated before choosing the machine. Too high or too low capacity can impair comfort and efficiency. Second, the condition of the duct network should be checked. Even the best central heat pump will not perform at its best if air circulation is poor. Third, the outdoor location must be chosen carefully. The unit needs to breathe, remain accessible, and be protected as much as possible from seasonal constraints.

It is also preferable to consider HVAC maintenance from the outset. A unit installed too low, too close to an obstacle, or in a difficult-to-access location will complicate future cleanings. Finally, it is essential to work with a company that understands local standards, electrical requirements, Quebec's climatic realities, and the expectations of homeowners in the region.

    What people ask us about this kind of work

    11 questions
    Can I keep my current ducts?
    Often, yes: the central heat pump connects to the existing ducts. We check their condition and size during the estimate.
    What happens in extreme cold?
    The indoor module (furnace or air handler) works with the central heat pump and takes over in extreme cold.
    Furnace, air handler, ducted: what is the difference?
    The furnace or air handler is the indoor module of the central system. A ducted system hides in the ceiling: all you see are small supply grilles.
    Are there grants?
    Depending on the equipment and your situation, assistance programs may apply. AirGreen checks the exact combination before quoting an amount. See the grants.
    Do I need a permit?
    Rules vary from city to city. See permits and by-laws, and we check for your address.
    How much can I save?
    Hydro-Québec says a heat pump can be up to three times more efficient than baseboards for heating in the colder months. The result depends on the house, the climate and how it is used.
    How is the LogisVert assistance calculated?
    For ENERGY STAR cold-climate certified heat pumps, Hydro-Québec lists assistance of $120 per 1,000 BTU/h of heating capacity at −8 °C. AirGreen checks the exact model before quoting an amount; only Hydro-Québec confirms the assistance granted. See the grants.
