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 compact, high-performance, and well-integrated central installation on a residential balcony in Auteuil

In the peaceful sector of Auteuil, in Laval, our AirGreen team recently carried out the HVAC installation of a MIDEA EVOX G3 2-ton central heat pump, a project that required particular attention to available space, exterior aesthetics, and the stability of the unit on a residential balcony.

The image of this installation perfectly illustrates a type of project we regularly encounter in the greater Montreal, Laval, Longueuil areas, on the North Shore and South Shore: replacing or installing a high-performance central system in an environment where every detail counts. Here, the outdoor unit was installed on an elevated metal structure, solidly fixed to a balcony surface, while maintaining functional access to connections, good airflow, and clean integration with the building.

Why the MIDEA EVOX G3 2-ton was an excellent choice for this property in Laval

The MIDEA EVOX G3 central heat pump is particularly attractive to homeowners looking for a balance between comfort, energy efficiency, reliability, and heating performance. In this project in Auteuil, the 2-ton size was well-suited to the residence's needs, considering the volume to be treated, the interior configuration, and the client's expectations for four-season comfort.

This machine is designed to provide efficient heating during Quebec winters, while ensuring stable air conditioning during warm periods. For a homeowner in Laval, this type of system represents a very relevant solution when one wants to reduce reliance on less efficient systems, improve overall comfort, and enjoy more uniform operation throughout the house.

An outdoor installation that required precision and method

One of the most important elements of this project was the location of the outdoor unit. In the photo, we can see that the available space is limited by the brick wall, the balcony railing, and the proximity of the neighboring building. This type of configuration requires rigorous planning, as a central heat pump should never be placed haphazardly.

Our technicians paid particular attention to several essential points:

  • the stability of the metal base;
  • clearance around the outdoor coil;
  • protection of refrigerant connections;
  • future access for HVAC maintenance;
  • reduction of vibrations transmitted to the structure;
  • visual integration of the unit into the existing environment.

The elevated support also protects the unit against snow accumulation, standing water, and debris on the ground. In residential areas like Auteuil, where many installations are near balconies, side entrances, or restricted backyards, this approach maximizes the system's lifespan while facilitating future interventions.

Particular attention to ducts and connections

In this installation, the insulated ducts and connections to the building were neatly grouped to achieve a clean and durable result. In a central HVAC installation, the quality of the connections is as important as the choice of the machine itself. A good heat pump that is poorly installed can lose efficiency, generate unwanted noise, or experience premature problems.

At AirGreen, we pay particular attention to how refrigerant lines, communication cables, and electrical connections are installed. The objective is simple: to allow the MIDEA EVOX G3 to operate in the best possible conditions, while ensuring a visually clean result.

The concrete advantages of a 2-ton central heat pump

A 2-ton central heat pump is often recommended for moderate-sized houses or residential units, when the calculated thermal load justifies it. Sizing is an essential step. A machine that is too small could run constantly without achieving the desired comfort. A machine that is too large could lead to short cycling, reduce comfort, and impair efficiency.

In this specific case, the choice of the MIDEA EVOX G3 2-ton allowed for a good balance between performance and consumption. This type of system offers several advantages:

  • heating and cooling from the same equipment;
  • better air distribution when connected to an appropriate central network;
  • more uniform comfort in rooms;
  • efficient operation for a large part of the year;
  • possibility of improving the energy value of the property;
  • potential compatibility with certain subsidy programs according to current criteria.

Subsidies and energy efficiency: a point to check before installation

Homeowners in Montreal, Laval, Longueuil, on the North Shore and South Shore often ask us the same question: can this installation be eligible for a subsidy?

The answer always depends on the specific model, the installed combination, the residence, the program available at the time of installation, and the current technical requirements. The MIDEA EVOX G3 range is often considered for projects where energy efficiency is a priority, but it is always necessary to validate exact eligibility before confirming a quote.

At AirGreen, we help our clients understand the important criteria before making a decision. This avoids unpleasant surprises and allows for clear comparison of options.

Mistakes to avoid when installing a central system on a balcony

This project in Auteuil clearly shows why it is important to entrust this type of installation to an experienced team. Installing an outdoor unit on a balcony or restricted surface may seem simple, but several errors can compromise the system's performance.

The most common mistakes are:

  • placing the unit too close to a wall or obstacle;
  • neglecting the stability of the support;
  • forgetting access for maintenance;
  • installing ducts without adequate protection;
  • underestimating vibrations;
  • choosing a machine without correctly calculating actual needs;
  • not taking into account snow accumulation in winter.

In this project, our approach was to secure the unit, optimize its positioning, and maintain a clean, accessible, and durable installation.

An installation designed for future maintenance

A good HVAC project is not limited to the day of installation. It is also important to consider the years that follow. A central heat pump must be able to be inspected, cleaned, and maintained properly. Access to the service panel, coil, connections, and main components must remain convenient.

This is why we avoid installations that are too cramped or difficult to access. In this case in Laval, the positioning on a stand allows for reasonable access while respecting the balcony's constraints.

AirGreen's experience in central installations in Laval

Our teams regularly carry out similar installations in Laval, whether in Auteuil, Sainte-Rose, Vimont, Chomedey, or Duvernay. Each sector has its peculiarities: townhouses, condos, duplexes, narrow balconies, compact backyards, brick walls, limited access, close neighbors.

This local experience allows us to anticipate difficulties even before work begins. We know that a successful installation depends as much on the machine as on the on-site execution. The MIDEA EVOX G3 is an excellent option when it is well-selected, well-installed, and well-suited to the property.

A clean, stable, and professional result

The final result of this installation in Auteuil accurately reflects what we aim for in a residential project: a well-positioned outdoor unit, a solid base, clean connections, good airflow, and discreet integration into the available space.

For the client, this means a more comfortable, more efficient system, better adapted to the actual needs of the home. For our team, it represents another central installation carried out with rigor in the greater Laval area.

Your numbers

And at your place?

Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.

Before / afterThe cost of the same heat

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):

Before · baseboards11.142¢/kWh
After · heat pump–

Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.

    Frequently asked questions

    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.
    Will my current thermostat work?
    Not always: the thermostat has to run the heat pump and the backup heat. We check compatibility during the estimate.
    Central or wall units: which one?
