The tour

Take a tour of the installation

Each number is a point we check on site. Switch between summer and winter to watch air and heat move.

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.

The job

When it comes to year-round comfort in a single-family home in Laval, a central heat pump remains one of the most effective solutions… provided the indoor installation is done carefully. The photo clearly shows what makes the difference between a quick fix and a system built to last : a properly positioned central air handler, clean connections, a condensate drain, and proper service access.

At AirGreen , we love this type of project because it combines performance, ease of use and discreet integration into the home — a true “set and forget” for the client, while keeping the mechanics accessible for maintenance.


A typical situation in Fabreville: unfinished basement, mechanical space to be optimized

The decor speaks for itself: exposed wood structure, technical basement, sheet metal plenums, compact service area. This is very common in Fabreville and, more broadly, in Laval: the goal is a high-performance central system, but without wasting space , and without turning the mechanical room into a headache.

In this type of environment, our approach is always the same:

  • maintain a logical airflow (return/supply),

  • to facilitate filter changes and access to the panels,

  • secure the drainage of condensate ,

  • reduce vibrations and unwanted noise,

  • and protect the installation against “small problems” that become big (water leaks, condensation on pipes, poorly protected electrical connections, etc.).


Machine type identified: central system (air manager) for central heat pump

This isn't a wall-mounted unit. We see a large internal cabinet connected to conduits (sheet metal plenum), with:

  • copper refrigeration lines (liquid + suction) coming out of the office,

  • insulation along the suction line (to prevent condensation),

  • a PVC condensate drain (drainage),

  • a nearby filter rack/location,

  • and multi-point access panels (convenient for maintenance).

This is exactly the configuration of a Midea air manager paired with an outdoor central heat pump (depending on the pairing, we are typically in a family of the type Midea EVOX G3 or Midea ATOM X , very consistent for residential).


Brand (truth provided): Midea

Even if we could guess something else from the label, here we respect your instruction: the brand is Midea , period — and that's what we're putting forward in the project.


Selected model (consistent with the range): Midea EVOX G3 (central system)

In the photo, the label is not clearly legible. Rather than inventing an exact number, we are using a model consistent with this type of residential installation: Midea EVOX G3 , a modern central system (often associated with configurations of 1.5 to 5 tonnes depending on the sizing).

In a typical single-family home in Laval, capacities are often around 36,000 BTU (3 tonnes) , but at AirGreen, the final capacity is always confirmed by a load calculation (insulation, windows, orientation, volume, lifestyle, etc.). This is key to avoiding oversized (less comfortable) or undersized (less efficient) systems.


Prominent installation details: what we like (and why)

1) A raised cabinet on a metal base

The air manager is installed on a sheet metal base/platform . This detail is far from being merely aesthetic:

  • This protects the equipment if the floor absorbs moisture.

  • This helps manage drain passage and access to conduits.

  • and it allows for better organization of the connections.

2) Clean refrigeration connections + suction insulation

The insulated suction line (the large copper pipe with white insulation) is clearly visible. This is essential for:

  • to avoid condensation and water droplets,

  • stabilize performance,

  • limit the risk of long-term corrosion on copper.

3) Condensate drain provided (and visible)

The small PVC pipe on the floor indicates a condensate drain. On a central system, this is a critical point: a poorly installed drain = risk of backflow, water damage, mold, and unnecessary service calls.

Our AirGreen standard: correct slope, solid connections, logical path, and easy access if cleaning is required.

4) Sealed conduits (aluminum tape/sealant) and neat transitions

The sheet metal joints are sealed. In a central installation, every air leak in the mechanical room means:

  • Energy paid for… to heat the basement,

  • less stable air pressure,

  • and sometimes more noise in the network.

5) Service access: signs and clearance

The multiple fasteners/panels on the cabinet indicate a device designed for maintenance. And that's important: a high-performing central system must remain maintainable (coil, fan, electronics, drain, etc.).


Why a Midea central heat pump is a logical choice in Laval

In Fabreville, many homes already have a ductwork system (or a basement that allows for its addition). A central heat pump then becomes a very attractive solution:

  • Uniform comfort across multiple rooms

  • Central filtration (a big plus for dust, hair, allergies)

  • Aesthetics : no wall-mounted headboards in the rooms

  • Simple to use : a central, logical and stable thermostat

  • Good performance in mid-season (and real savings vs. direct electric heating)

And with a range like Midea, we aim for a balance: performance, reliability, parts availability, and compatibility with common residential configurations.


The points we systematically check (for an “AirGreen” result)

Even though the photo shows a very clean job, here's what we always frame in this type of project:

  • Sizing (heating/cooling load)

  • Airflow and static network (comfort + noise)

  • Pipe sealing

  • Humidity management (especially in spring/summer)

  • Drainage and water safety (prevention, prevention, prevention)

  • Easy filter access (otherwise… it will never be changed)

  • Vibrations and mechanical isolation

  • Positioning for future maintenance (without acrobatic dismantling)


Recommended maintenance: performance is protected

A central heat pump is robust, but it's still a machine that breathes. To maintain performance and avoid preventable breakdowns:

  • Filter : check regularly (often every 1–3 months depending on usage)

  • Annual inspection : drain, coil, connections, pressures, general operation

  • Cleaning : as needed, depending on dust and household conditions

It's simple: a clean system consumes less, heats better, cools better, and lasts longer.


Conclusion: A well-executed Midea central installation, ready for Greater Montreal's winters.

This installation in Fabreville (Laval) perfectly illustrates what we at AirGreen strive for: a clean , functional setup designed for accessibility and durability. With a Midea central heat pump ( EVOX G3 model from the consistent product line), we achieve year-round comfort, ideally suited to homes seeking a discreet, stable, and efficient system.

If you want to replicate this level of finish (or optimize an existing mechanical room), we know exactly what to check — from sizing to the last drainage detail.

The steps

The big day, step by step

The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.

Step 1 of 9The on-site estimate

We look at the ducts, the current indoor module, the electrical panel and the planned spot for the outdoor unit.

  1. The on-site estimateWe look at the ducts, the current indoor module, the electrical panel and the planned spot for the outdoor unit.
  2. The quoteThe equipment combination, capacity and price, in writing. We check whether the combination qualifies for assistance programs.
  3. Getting readyAccess protected, old unit disconnected and removed when it is being replaced.
  4. The indoor moduleElectric furnace or air handler, with its coil, connected to the supply and return ducts.
  5. The outdoor unitOn a level base, raised above the snow, with free space all around.
  6. The refrigerant linesInsulated, they enter through a sealed opening and run to the indoor coil.
  7. Electrical and thermostatDedicated circuits, accessible disconnect, a thermostat that works with the heat pump and the backup heat.
  8. Tests and start-upLeak test, vacuum, start-up, airflow check and a test of both modes.
  9. The walkthroughFilter, thermostat, backup heat in extreme cold: what to know before winter.
Your numbers

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.

Size checkYour electric furnace, in BTU/h
–BTU/h of installed electric heat

    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.

    Through the seasons

    What to do, season by season

    Three habits per season for this unit. They take a few minutes and prevent many calls.

    • Check the indoor module's filter.
    • Clear winter debris from the outdoor unit.
    • Test cooling before the heat arrives.
    At your place

    Is your home ready?

    Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.

    0 / 6 checked
    True or false

    Four statements: true or false?

    It all comes down to details you have just seen.

    1. A central heat pump uses the house's ducts.

    2. In extreme cold, electric backup heat can take over.

    3. The filter only gets changed when the unit breaks down.

    4. You can reuse the old unit's size without checking.

    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.
    Is the estimate free?
    Yes. The on-site estimate is free and the quote follows within 24 hours. Book my free estimate.
