Installation of a Midea central heat pump in Terrebonne (North Shore): discreet performance and consistent comfort, even in the attic
The full story

The article, chapter by chapter

In many single-family homes on the North Shore , particularly in Terrebonne , the space available for HVAC equipment is often located in the attic . This type of installation requires rigorous planning, precise execution, and a system capable of providing efficient heating and cooling without compromising comfort.
This is exactly the context of this AirGreen project, installing a Midea central heat pump suspended under the roof structure , with distribution via ducts.


Why a Midea central heat pump in a house in Terrebonne?

The residences in Terrebonne have typical characteristics:

  • detached or semi-detached houses,

  • existing or easily optimized conduit networks,

  • need for consistent comfort across one or two floors,

  • harsh winters and increasingly hot summers.

In this context, a Midea central heat pump is a strategic choice. It allows you to replace or supplement traditional electric heating, while providing efficient and quiet air conditioning, without multiplying the number of visible units in the house.


Machine type: Central heat pump with suspended air manager

The photo clearly shows a Midea indoor air manager installed in the attic , suspended from the structure using sturdy metal brackets . The following are visible:

  • the central control cabinet of the heat pump,

  • insulated ducts connected directly to the unit,

  • electrical cables and control elements,

  • an installation designed to minimize vibrations and facilitate maintenance.

This is unequivocally a central heat pump , perfectly suited to single-family homes on the North Shore.


Installed model: Midea EVOX G3 (consistent core configuration)

Even though the exact model is not legible in the photo, the format, design and application correspond perfectly to a Midea EVOX G3 central heat pump (current Midea central range).

This type of system is known for:

  • its compatibility with residential ducts ,

  • its high energy efficiency ,

  • its reliability in Quebec winter conditions ,

  • its installation flexibility (basement, mechanical closet or attic).


Prominent installation details visible in the photo

1) Suspended installation in the attic

Rather than placing the unit directly on the ground, here it is suspended from the framework using sturdy metal supports.
Benefits :

  • reduction of vibrations transmitted to the structure,

  • better protection against moisture or dust on the floor,

  • optimal clearance for conduits and drainage.

2) Carefully connected insulated ducts

Exposed insulated flexible ducts are essential in an attic:

  • They limit heat loss in winter.

  • reduce heat gain in summer

  • prevent condensation in an unheated space.

Inadequate insulation in this area would severely impair the overall performance of the system.

3) Next generation refrigerant (A2L)

We note the label indicating an A2L refrigerant , typical of recent Midea systems.
This implies:

  • an installation that complies with current standards

  • strict procedures (sealing, vacuum sealing, precise loading)

  • A professional approach is essential for safety and sustainability.

4) Intelligent space management

In an attic, every inch counts. The installation was designed with this in mind:

  • maintain reasonable access to the unit,

  • to avoid crushing the pipes,

  • ensure adequate air circulation around the manager.


The tangible benefits for the occupants

Uniform comfort throughout the house

Thanks to distribution via conduits:

  • Each room receives a balanced amount of air.

  • Temperature variations are reduced,

  • The comfort is consistent, from the main floor to the bedrooms.

Invisible and aesthetically pleasing system

No wall units are visible in the living areas. Everything is concealed in the attic, which is particularly appealing to homeowners who wish to maintain a clean interior aesthetic.

Long-term energy savings

A properly sized and installed Midea central heat pump allows you to:

  • to reduce electric heating consumption,

  • to improve the overall efficiency of the home,

  • to take advantage of a 2-in-1 system (heating + air conditioning).


The AirGreen approach for this type of project in Terrebonne

For central installations in attics, our method is always structured:

  • comprehensive assessment of the existing conduit network,

  • choosing the Midea system best suited to the surface area and insulation,

  • stable and safe suspended installation

  • insulation and sealing of ducts,

  • reliable condensation drainage

  • comprehensive functional and balancing tests,

  • clear explanation to the customer on maintenance and use.

It is this rigor that guarantees lasting performance, even after several harsh winters.


Recommended maintenance for a central heat pump in an attic

A central system installed in an attic requires special attention:

  • Regular filter replacement,

  • annual inspection of the drainage and the coil.

  • checking the insulation of the ducts,

  • Preventive maintenance to avoid yield losses.

Proper maintenance prolongs the system's lifespan and maintains its energy efficiency.


Conclusion: a Midea central solution perfectly suited to the North Shore

This installation in Terrebonne demonstrates how a Midea central heat pump , installed methodically and precisely, can offer superior, discreet and lasting comfort in a single-family home.

At AirGreen , we adapt each installation to the realities of Quebec buildings and climate, to deliver reliable, high-performance systems designed to last.

Your numbers

The job tools

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.

    The steps

    How the job unfolds

    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.

    What we check on a job like this one

    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.

    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.
