It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.
The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.
A shut-off switch near the outdoor unit isolates it safely for service.
Sitting on the indoor module, it moves heat between the house air and the refrigerant.
Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.
Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.
It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.
It runs the heat pump and the backup heat. It must be compatible with the installed system.
A well-thought-out central installation in a residential area of Fabreville
In Fabreville, in the west of Laval, our AirGreen team completed the installation of a MIDEA EVOX G3 2.5-ton central heat pump, a solution designed to improve the overall comfort of a family home using the existing or adapted ductwork. This type of project requires more than just installing equipment: it involves evaluating the actual capacity of the house, the location of the outdoor unit, indoor air circulation, clearances around the unit, accessibility for maintenance, and the expected performance in both heating and cooling.
In the photo of this installation, one immediately notices an outdoor unit installed cleanly and stably, on metal supports, along the foundation wall. This choice is not insignificant. In a residential neighborhood like Fabreville, where lots can be narrow and side access is sometimes limited, the positioning of a central heat pump must meet several constraints simultaneously: air clearance, distance from windows, protection against snow accumulation, mechanical stability, outdoor aesthetics, and ease of access for future HVAC maintenance.
The MIDEA EVOX G3 installed here is a 2.5-ton central heat pump, with a nominal capacity of approximately 30,000 BTU, well-suited for many medium-sized single-family homes when sizing is properly validated. AirGreen presents this model as offering a cooling capacity of 30,000 BTU, heating operation down to approximately -30 °C, and announced efficiencies of SEER2 17.2 and HSPF2 10.8 for this 2.5-ton configuration.
Why a central heat pump instead of a wall-mounted system?
In many homes in Laval, Montreal, Longueuil, the North Shore, and the South Shore, homeowners hesitate between a wall-mounted heat pump and a central heat pump. The choice rarely depends on a single factor. Internal configuration, the presence or absence of ducts, the type of existing heating, the desired comfort level, and energy objectives must all be considered.
In this project in Fabreville, the central solution allowed for more uniform distribution throughout the house. Unlike a wall-mounted system that primarily treats an open area or a specific section, a 2.5-ton central heat pump can supply several rooms through the ventilation network. For a family wishing to avoid temperature differences between the ground floor, bedrooms, and living areas, this approach is often more consistent.
The MIDEA EVOX G3 is also interesting for projects where an existing system needs to be modernized without completely transforming the interior architecture. The manufacturer highlights a modular design, compatibility with various electrical configurations, wireless communication between certain components, and a design aimed at simplifying installation and integration into sometimes restricted mechanical spaces.
Precisely chosen outdoor location
The outdoor unit visible in the photo was installed near the side wall, on suitable supports, with particular attention paid to its height relative to the ground. In Fabreville, as everywhere in Greater Montreal, this decision is essential. An outdoor heat pump installed too low can be exposed to snow accumulation, splashing, constant humidity, or debris. Conversely, an installation that is too high or poorly supported can create vibrations, detract from aesthetics, or complicate technical access.
Here, the unit is installed above ground level, with solidly attached legs. The proximity of a basement window and a wall outlet is also visible. Our team therefore had to ensure necessary clearances, avoid any obstruction of airflow, protect refrigerant lines, and ensure a clean installation along the exterior siding.
This kind of detail is often what distinguishes a standard installation from a truly professional HVAC installation. At AirGreen, we analyze the building before installing the unit, because a poor location can cause several medium-term problems: reduced performance, excessive noise, ice accumulation, difficult access for cleaning, or discomfort near openings.
Specific challenges of this Fabreville installation
Each central heat pump installation has its own specificities. In this case, the main challenge was to achieve a clean integration in a relatively limited side space, while maintaining sufficient access around the unit. The grassy area, the proximity of the foundation, the presence of low windows, and the alignment of the exterior cladding required a measured approach.
Our team paid particular attention to three elements:
- The stability of the outdoor unit, to limit vibrations and ensure good durability.
- The protection of connections, especially refrigerant and electrical lines.
- Air circulation around the heat pump, essential for maintaining good heating and cooling performance.
The result is a discreet, functional, and building-adapted installation. The unit integrates cleanly against the side facade, without unnecessarily encroaching on the outdoor space. For homeowners, this means efficient equipment that remains accessible, but does not visually dominate the exterior landscaping.
The MIDEA EVOX G3 2.5 tons: a serious choice for Quebec's climate
The MIDEA EVOX G3 falls into a category of central systems that meet the current expectations of Quebec homeowners: energy efficiency, four-season comfort, compatibility with various residential installations, and the ability to operate in demanding winter temperatures. The manufacturer indicates that the EVOX G3 range can achieve up to 19.0 SEER2, 12.5 EER2, and 10.8 HSPF2-4, depending on configurations, with a heating capacity announced at 100% down to -25 °C for some systems.
A 2.5-ton capacity well-suited to Laval homes
A 2.5-ton central heat pump is not chosen by chance. A common mistake is to believe that a larger unit will automatically provide better comfort. In reality, an oversized system can cause short cycling, poor dehumidification, premature wear, and more pronounced temperature fluctuations. Conversely, an undersized unit can run too long without reaching the desired temperature.
For this Fabreville home, the 30,000 BTU capacity corresponded to the actual needs of the building, taking into account the volume to be treated, insulation, heat losses, air distribution, and daily use of the house. It is precisely for this reason that we always insist on evaluation before installation. A MIDEA EVOX G3 2.5-ton central heat pump can be an excellent choice, but only if it is correctly selected and installed.
A solution compatible with heating and cooling needs
Comfort in Laval is not limited to cooling during heat waves. A good HVAC installation must also take into account long heating periods, rapid temperature variations, and indoor humidity. The MIDEA EVOX G3 is designed to provide efficient heating in cold climates, while ensuring powerful cooling during the summer.
For homeowners, this translates into several concrete benefits:
- More stable temperature throughout the house.
- Better humidity management in summer.
- Potential reduction in reliance on a less efficient heating system.
- Quieter and more gradual operation than a traditional system with abrupt cycles.
- More discreet interior integration when a duct network is already present.
In this Fabreville installation, the goal was precisely to provide uniform comfort without multiplying visible wall units in the rooms. The central heat pump meets this expectation by using a more global air distribution.
LogisVert subsidy and eligibility: a point to check at the time of installation
Subsidies often play an important role in the decision to install a central heat pump. For the MIDEA EVOX G3 2.5-ton model, AirGreen indicates eligibility for LogisVert financial assistance of up to $2,880 or $3,000 depending on the version and the update applicable at the installation date.
However, it is essential to remember that amounts and eligibility lists can change. Hydro-Québec specifies that the list of eligible heat pumps and the amount of financial assistance may vary over time, and that reference should be made to the list in effect at the time the heat pump is installed.
At AirGreen, we support our clients through this step. We verify the configuration, model, documentation, and necessary information so that the client can submit their file correctly after installation. This assistance is particularly appreciated, as an error in model, invoice, or configuration can slow down or jeopardize a subsidy application.
Mistakes to avoid during a central installation
A high-performance central heat pump can lose much of its potential if the installation is poorly planned. Here are the mistakes we regularly observe when clients call us to correct or evaluate existing installations:
Choosing capacity based solely on surface area
The surface area of the house gives an indication, but it is not enough. Insulation, windows, orientation, air infiltration, ceiling heights, and duct configuration are equally important.
Installing the outdoor unit too close to an obstacle
A heat pump needs to breathe. If air is blocked by a wall, fence, hedge, or outdoor bin, performance may decrease. In Fabreville, our team specifically chose a location that allows for adequate airflow.
Neglecting height relative to the ground
In Greater Montreal, snow and ice are not minor details. Installing the unit on solid supports better protects the appliance during winter and facilitates maintenance.
Underestimating the importance of the duct network
A central heat pump depends on the quality of air distribution. Poorly sized, leaky, or obstructed ducts can impair comfort, even with an excellent appliance.
Forgetting annual maintenance
Regular HVAC maintenance helps preserve performance, coil cleanliness, air quality, and system lifespan. A central unit must be inspected, cleaned, and checked according to its use.
The AirGreen approach: precision, cleanliness, and follow-up
This installation in Fabreville perfectly illustrates our way of working. We don't just aim to install a machine. We aim to deliver a complete, reliable, and coherent system for the house. This includes equipment selection, site preparation, mechanical installation, connections, functional testing, and customer advice after commissioning.
Our technicians pay particular attention to the exterior finish. In the photo, the MIDEA unit is neatly aligned, well-cleared, and mounted on a stable structure. These choices facilitate future interventions and reduce the risk of problems related to vibrations, drainage, or ground accumulations.
We regularly work in similar contexts in Montreal, Laval, Longueuil, on the North Shore and South Shore, with houses of very different styles: bungalows, cottages, duplexes, houses with existing furnaces, renovated properties, and residences where mechanical space is limited. This experience allows us to offer tailored solutions rather than forcing the same installation model everywhere.
What homeowners appreciated in this project
In this Fabreville project, the owners wanted a sustainable solution that would improve comfort without multiplying visible equipment. They also wanted an appliance capable of meeting Laval's climatic realities: humid heat in summer, intense cold in winter, and transition periods where heating and air conditioning might be needed within days of each other.
After installation, the most appreciated points were the discretion of the outdoor unit, the cleanliness of the work, and the prospect of more evenly distributed comfort throughout the house. The MIDEA EVOX G3 central heat pump allows for modernization of the residential system without altering the interior appearance of the rooms, which is a significant advantage for many families.
Practical advice for homeowners in Fabreville and Laval
For those considering a central heat pump in Fabreville or elsewhere in Laval, here are some recommendations based on our field experience:
- Have the actual required capacity verified before choosing the model.
- Ensure the outdoor unit will be installed at a height suitable for Quebec winters.
- Request a check of the ductwork condition.
- Confirm eligibility for subsidies before installation.
- Plan for regular maintenance from the first year.
- Choose a contractor who understands mechanics, electricity, ventilation, and local requirements.
A central heat pump is a significant investment. When properly installed, it can transform the comfort of a home. When poorly planned, it can become a source of frustration. This is why our role is not limited to recommending a brand or capacity: we analyze the entire project.

What would it look like at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
