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.

When a family in Terrebonne contacted us to upgrade their heating and air conditioning system, their goal was clear: to improve year-round comfort while reducing their electricity bill and preparing for increasingly unpredictable winters. We recommended the installation of a Midea EVOX G3 central heat pump , a high-performance, reliable system perfectly suited to the climate of Greater Montreal.


Context of the house in Terrebonne

The property is a typical single-family home on the North Shore:

  • Partially buried basement made of poured concrete;

  • Exterior cladding in pale vinyl;

  • Basement windows close to the ground, requiring careful management of space and clearance;

  • Wooded backyard, with natural soil and a small border of concrete blocks along the foundation.

These factors guided us in choosing the exact location of the Midea condenser and in designing the support structure. The objective: to protect the unit from snow, water, and debris, while respecting the necessary clearances for ventilation and maintenance.


Type of system installed: a Midea central heat pump

For this project, we installed a Midea EVOX G3 central heat pump , an ideal solution for homeowners who want:

  • To replace or assist an existing hot air system;

  • Enjoy air conditioning in the summer and high-efficiency heating in the winter ;

  • Distribute air evenly throughout the house using existing ducts.

The Midea EVOX G3 is a range of central heat pumps operating with a new generation refrigerant, designed for:

  • To offer excellent energy efficiency;

  • Maintaining good heating capacity even in cold weather;

  • Reduce the environmental footprint compared to older systems.


A carefully designed outdoor installation, specifically tailored to Quebec winters.

The photo highlights several key aspects of our installation approach:

1. Elevated steel wall bracket

The Midea outdoor condenser is installed on a galvanized steel bracket securely anchored to the foundation . This type of installation offers several advantages:

  • Snow protection : the unit is raised above the snow and ice accumulation line, which facilitates natural defrosting and prevents the fan blades or the bottom of the unit from being buried;

  • Stability and durability : the steel support is sized to support the weight of the condenser and withstand freeze-thaw cycles;

  • Vibration elimination : Anti-vibration pads are installed under the feet of the device to reduce vibrations transmitted to the building.

2. Clearances respected for performance and maintenance

The Midea unit is positioned at an appropriate distance from the house wall, the edge of the blocks, and the basement windows. This allows:

  • Good air circulation through the condenser;

  • Easy access for seasonal maintenance and diagnostics;

  • Optimal management of condensate and ice.

3. Land and water runoff management

Beneath the device, there is river stone infill and a slightly sloping floor. This configuration helps to:

  • Clear away rainwater and snowmelt;

  • Avoid pockets of stagnant water under the condenser;

  • Protect the foundation and metal structure against long-term corrosion.


Integration with the existing interior system

Inside, the Midea EVOX G3 central heat pump is connected to an air handling unit/electric furnace and the existing ductwork in the house. This configuration allows for:

  • Uniform distribution of heat and cold throughout all rooms;

  • Possibility of adding or rebalancing certain ventilation outlets to improve comfort;

  • Precise temperature control thanks to a modern programmable thermostat , compatible with various eco modes.

The old main heating source is thus either replaced or greatly relieved, which prolongs its lifespan and reduces overall energy consumption.


Winter performance in Terrebonne

Winters in Terrebonne are harsh, with periods of intense cold, wind, and frequent thaws. The Midea EVOX G3 was specifically selected for:

  • Maintaining a good level of heating at low outside temperatures ;

  • Reduce reliance on backup electrical components;

  • Offers quieter and more stable operation than older compressors.

By combining this heat pump with good insulation and a properly set thermostat, homeowners can:

  • Reduce their electricity bill;

  • Enjoy a comfortable home in every season;

  • Reduce their greenhouse gas emissions compared to fossil fuel heating systems.


Aesthetics and integration into the home

While performance is a priority, aesthetics are very important to our clients. Regarding this project:

  • The dark color of the Midea condenser blends well with the concrete foundation and the light-colored cladding;

  • The sleek metal stand gives a professional and discreet look ;

  • The recessed position, along the side of the house, limits the visual impact from the main courtyard.

The result: a high-performance system that blends seamlessly into the residential environment.


Maintenance and longevity of the Midea heat pump

To fully benefit from the Midea EVOX G3 central heat pump , we recommend:

  • Annual preventative maintenance (refrigerant check, electrical connection inspection, coil and fan cleaning);

  • Regular cleaning of the area around the condenser (leaves, branches, snow);

  • A minimal clearance from any nearby objects or landscaping.

During the project handover, we explained to the client:

  • The basic operation of the Midea heat pump;

  • Heating, air conditioning and defrosting modes;

  • The right reflexes in case of unusual noise or a severe winter storm.

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.

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.

    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.
