MIDEA28 4-Zone Heat Pump | Compressor: 48,000 BTU | Montreal, Laval, South Shore and North Shore

Stable and lasting comfort for your entire property

At AirGreen, we offer the MIDEA28 4-zone heat pump with 48,000 BTU compressor , a complete heating and cooling solution for homeowners looking for reliable performance. With its multi-zone design and operation down to -30 °C, this model fits perfectly with the needs of homes and businesses in Montreal , Laval , Longueuil , the North Shore and the South Shore . Here we would like to present the concrete details of this product, the specifics of its installation and the benefits we have observed among our customers.

Why choose a 4-zone heat pump?

The multi-zone heat pump meets the realities of large properties, or those whose room distribution sometimes complicates air diffusion. With the MIDEA28 4-zone heat pump , you benefit from a single outdoor unit to serve up to 4 indoor units, each individually controllable. This allows for remarkable thermal balance in the different zones of a building, while promoting a reduction in energy consumption thanks to the modularity of the device.

Essential technical characteristics

• Heating capacity : down to -30°C to face our Montreal winters.

• Cooling capacity : 48,000 BTU , ideal for covering large areas.

• R-454B refrigerant gas : recognized as a more environmentally friendly solution than conventional gases.

• SEER2 : 23.0, a high rating that indicates excellent seasonal efficiency in air conditioning mode.

• HSPF2 : 11.0, reflecting appreciable heating performance.

• EER2 : 12.0, for a satisfactory ratio between the electrical energy consumed and the cooling delivered.

• Optional WiFi : Allows remote management and monitoring, very convenient for owners wanting smart control.

• Noise level : 65 dB(A) in outdoor mode, which remains discreet in most residential environments.

• Warranty : 12 years on the compressor, 12 years on parts and 10 years on labor. An extended warranty (10-10-10) is also included.

Real example of installation in Boucherville

We recently installed a MIDEA28 4-zone heat pump in a home in Boucherville, on the South Shore . The homeowner had a basement, a ground floor, and an upper floor, each with different thermal requirements. By adding four wall-mounted units tailored to each space, the family was able to benefit from precise temperature control in the bedrooms, family room, and kitchen. The user configured time slots specific to each unit, reducing overall energy costs while ensuring consistent comfort.

How 4-Zone Design Promotes Energy Savings

1. Individualized management : Heat or air condition only the rooms actually occupied.

2. Performance by zone : Limit losses in low-traffic areas.

3. Automatic adaptation : Thanks to the compressor inverter, the heat pump modulates its power according to the overall or specific demand of each zone.

LogisVert Grant

A crucial piece of information not to be overlooked: the LogisVert Provincial Grant associated with the MIDEA28 4-zone heat pump can reach $5,280 (updated May 1, 2025). This grant encourages the adoption of energy-efficient HVAC systems. We have often observed, during our interventions in Montreal , Laval and surrounding municipalities, that this type of financial support encourages homeowners to adopt greener solutions, by modernizing their old, less efficient electric heating or central air conditioning systems.

Installation process at AirGreen

We ensure that we deploy an optimal HVAC installation , taking into account:

• The location of the outdoor unit : the device must be placed in a location accessible for maintenance, while minimizing noise pollution for the resident and the neighborhood.

• Refrigeration duct passage : to ensure discreet integration, we provide wall passages reducing the length of piping.

• Indoor units : We evaluate both the surface area of ​​each room and the position of the furniture to take advantage of air circulation.

• Electrical requirements : with 220 V required, we ensure compliance with the standards and installation codes in force in Quebec.

Each step is overseen by our professional refrigeration engineers , who have years of experience in residential and commercial projects. We have often found that the success of a commissioning depends on a rigorous upstream study (load calculations, structural validations, etc.).

Recommended maintenance and follow-up

To maximize the durability of the MIDEA28 4-zone heat pump , we recommend regular HVAC maintenance , including:

• Cleaning the interior filters : to remove accumulated dust and pollen, which can affect the efficiency of the system.

• Check electrical connections : at least once a year, especially before the heavy heating season.

• Compressor Inspection : Check refrigerant charge, ensure there are no leaks and calibrate pressures according to manufacturer's recommendations.

• Examine exterior parts : remove anything that could obstruct the heat exchanger (leaves, debris, accumulated snow).

Our after-sales service technicians, based in Montreal and Boucherville , are trained to handle these interventions. The benefit of a proactive annual inspection is reflected in product longevity and energy savings. Some of our customers have experienced slightly reduced performance due to lack of maintenance, but prompt intervention has restored normal operation.

Adaptability to Quebec winters

Our winters are known for their extreme low temperatures. This is where the MIDEA28 4-zone heat pump stands out. Its operation down to -30°C makes it capable of providing efficient heating, even in the bitterest cold. Many of our customers on the North Shore , where temperatures can sometimes be harsher, confirm that their homes remain warm and comfortable without constantly resorting to expensive backup systems.

Some examples of successful installations with AirGreen

• Laval : Installation in a multi-room condo where the owner wanted to thermally insulate the bedrooms to save energy at night. The 4-zone heat pump allowed for lower temperature settings in unoccupied rooms.

• Longueuil : intergenerational house, two separate main areas, each with a dedicated interior unit, plus two other units for the basement and the garage converted into a workshop.

• Montreal : project in a rental duplex, where the owner chose to install two units per floor in order to offer its tenants the comfort of individual control while limiting the complexity of maintenance.

MIDEA28 and its multiple combinations

Although the unit is configured for 4 zones as standard, it can accommodate up to 6 indoor units (in the MIDEA range). This provides flexibility for future projects, in the event of a home extension or space transformation. In addition, compatibility with different types of units (wall-mounted, discrete ducts, consoles) opens up possibilities in terms of architectural configuration.

Tips for maximizing yield throughout the seasons

• Keep the outdoor unit clear : In winter, a buildup of snow or ice can reduce airflow and disrupt the performance of the heat pump.

• Program operating ranges : adjust the power required in each zone, taking into account the actual occupancy of the rooms (night/day, week/weekend).

• Carry out an annual inspection : call on our maintenance services, particularly before the cold weather and before the summer period.

• Monitor consumption : a sudden change in the electricity bill or the behavior of the heat pump may be a sign of an anomaly (clogged filters, drop in refrigerant, etc.).
