  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.

The job

A central MIDEA EVOX G3 installation in Brossard designed for performance, technical access, and durability

In Brossard, AirGreen recently installed a 2-ton MIDEA EVOX G3 electric furnace, also known as an air handler or indoor unit of a central system. This project was precisely the kind of intervention where field experience in HVAC installation makes all the difference: limited mechanical space, existing ductwork, visible electrical connections, required clearances, and clean integration between the new equipment and existing elements.

At first glance, the installation shows a typical mechanical environment found in many homes on the South Shore: a compact technical room, existing galvanized ducts, exposed wood structure, and piping very close to the unit. In this context, the goal was not just to install a new machine. It was to create a reliable, accessible, and safe system, capable of efficiently supplying the central network of the house while facilitating future maintenance.

The 2-ton MIDEA EVOX G3 is a particularly interesting solution for homeowners who wish to modernize their central system without multiplying wall-mounted units. It allows for air distribution through ducts, while benefiting from recent equipment, adapted to current residential heating and air conditioning needs.

Why choose a central electric furnace over a wall-mounted system?

Many clients in Brossard, Longueuil, Montreal, Laval, on the North Shore and South Shore ask us this question when comparing different HVAC options. A central system with an air handler often becomes the best choice when the house already has a functional duct network. It allows for more uniform air distribution, discreet integration, and better overall comfort in multiple rooms simultaneously.

Unlike a wall-mounted air conditioner or a single-zone wall-mounted heat pump, the central unit works with existing ducts. This allows the entire dwelling to be treated from a main mechanical point. In a family home, this approach is often more coherent when occupants want to avoid temperature differences between bedrooms, the living room, and common areas.

The MIDEA EVOX G3 electric furnace installed here acts as the internal heart of the system. It manages air circulation, integrates with the distribution network, and can be paired with an outdoor central heat pump depending on the complete project configuration. For the client, this means centralized comfort, better temperature stability, and a more discreet appearance in living areas.

Visible peculiarities of this installation in Brossard

The image of this installation highlights several important elements. The MIDEA unit is installed vertically in a technical space where every inch counts. To the right, we can see the connection to the galvanized metal duct network. Near the unit, electrical lines and mechanical components require precise installation to maintain the necessary clearances for access, maintenance, and safety.

We paid particular attention to three aspects:

  • the alignment of the unit with existing ducts;
  • the protection and organization of connections around the furnace;
  • future accessibility to service panels, technical labels, and internal components.

This last point is often underestimated. However, a good HVAC installer doesn't just think about the installation day. They also think about the technician who will have to return in a few years for HVAC maintenance, a diagnosis, a filter replacement, an electrical check, or an airflow adjustment.

Clean integration in a narrow mechanical room

In this project in Brossard, the space around the machine was limited. The ductwork, wooden structure, and existing elements imposed very concrete constraints. Installing a central electric furnace in this type of environment requires rigorous planning.

Before fixing the unit, our team always checks:

  1. the position of the plenum and return air;
  2. the general condition of existing ducts;
  3. connection possibilities without forcing the structure;
  4. clearances around access panels;
  5. electrical compatibility;
  6. the quality of the equipment's support and base.

A misaligned central system can lead to vibrations, pressure losses, excessive noise, or less efficient air circulation. That's why we always prioritize a stable, straight, and well-connected installation, even when space is tight.

The role of the MIDEA EVOX G3 air handler in daily comfort

The 2-ton MIDEA EVOX G3 air handler ensures air circulation through the central network. Its 2-ton capacity is suitable for several residential configurations, depending on the area, insulation, sun exposure, number of floors, and duct design.

In a Brossard home, where temperature differences between winter and summer can be significant, the quality of air distribution is essential. A good indoor unit helps reduce overly hot or cold zones, especially when the system is properly sized and the ducts are correctly assessed.

At AirGreen, we don't just install the equipment indicated on a box. We analyze the real context: the age of the house, the basement configuration, the type of ducts, access to the unit, and the client's expectations for comfort.

Mistakes to avoid during a central system installation

A central HVAC installation should never be treated as a simple mechanical substitution. Several errors can compromise the system's performance:

Neglecting existing ducts

A new appliance will not automatically correct a poorly designed, obstructed, or unbalanced duct network. Before installation, it is important to check if the ducts allow for good air circulation.

Installing the unit without planning for maintenance

A machine too tightly against a wall, pipe, or structure can become difficult to maintain. For this installation in Brossard, access to the service panels was considered from the outset.

Underestimating the importance of electrical connection

An electric furnace requires adequate and safe power supply. Connections must be clean, compliant, and well protected.

Choosing a capacity without analysis

A 2-ton unit can be ideal in some cases, but insufficient or excessive in others. The choice must be based on the house, not just the old equipment.

Why AirGreen recommends a comprehensive approach

Our HVAC approach is based on a simple idea: a good installation must be as reliable in five years as it is on day one. For this reason, we attach as much importance to the finish as to the performance.

In this installation of a 2-ton MIDEA EVOX G3 in Brossard, our team worked to ensure clean integration into the existing system. The connections were designed to limit mechanical constraints. The unit was positioned to preserve technical access. The final result is a compact, solid installation adapted to the reality of the house.

This precision is particularly important on the South Shore, where several properties combine old mechanical infrastructures with new energy efficiency needs. Homeowners want to improve their comfort without redoing the entire house. This is exactly where a specialized company like AirGreen provides real value.

Subsidies, efficiency, and choosing the right equipment

Subsidy programs can play an important role in choosing a central system, especially when an eligible heat pump is integrated into the project. Depending on the exact configuration, certain systems may be eligible for financial aid, particularly under programs like LogisVert. Eligibility always depends on the complete model, the indoor-outdoor combination, certified performance, and the rules in force at the time of installation.

For clients in Montreal, Laval, Longueuil, Brossard, the North Shore, and the South Shore, we always recommend verifying the specific equipment before making a decision. A small difference in model can affect eligibility or the potential subsidy amount.

In the case of a MIDEA EVOX G3, the interest lies in its ability to integrate into a modern central solution, with an excellent balance between comfort, technology, and accessibility. For many families, it is a serious alternative to more expensive systems, especially when the existing installation allows for retaining the ducts.

What the client gains with a well-executed installation

An installation like this offers several concrete benefits:

  • centralized air distribution throughout the house;
  • improved temperature stability;
  • a compact and well-integrated indoor unit;
  • technical access maintained for maintenance;
  • a solution compatible with current residential needs;
  • a clean finish in the mechanical room.

The client also gets a system installed by a team that understands local realities: Brossard homes, mechanical constraints of basements, climatic variations of the South Shore, winter and summer comfort requirements, and homeowner expectations for reliability.

An HVAC installation in Brossard that illustrates the value of well-planned work

This installation of a 2-ton MIDEA EVOX G3 electric furnace in Brossard clearly shows that an efficient central system begins with a good understanding of the building. The equipment is important, but how it is installed is just as crucial.

At AirGreen, we view each project as a complete package: machine, ducts, electrical supply, access, safety, future maintenance, and real occupant comfort. This approach allows us to deliver durable installations in Montreal, Laval, Longueuil, on the North Shore, and the South Shore.

For homeowners considering replacing an old furnace, adding a central heat pump, or modernizing their heating and air conditioning system, this project in Brossard is an excellent example of what to look for: well-chosen equipment, careful installation, intelligent integration, and an HVAC team that understands the details that matter.

    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?
    If the house has ducts in good shape, a central system heats and cools every room at once. Without ducts, wall units or a multi-zone are often simpler. We compare on site.
    Does AirGreen hold the required licences?
    Yes. AirGreen holds RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration and 16 Electricity.
