Everything we have written about this system.

A versatile HVAC solution adapted to our climate

When we talk about the MIDEA28 dual-head heat pump , we are talking about a system designed to optimize your heating and cooling comfort in the Montreal , Laval , Longueuil , North Shore and South Shore regions. At AirGreen, we have seen the effectiveness of this model in numerous installations, particularly in residential homes and commercial buildings concerned with energy efficiency. Thanks to its 36,000 BTU compressor , the MIDEA28 heat pump supports two separate indoor zones, allowing for precise temperature control and evenly distributed comfort in each room.

We know that in Quebec, temperatures can drop as low as -30°C. However, the MIDEA28 is designed to withstand harsh winters. Moreover, thanks to its SEER2 of 23.0 , its HSPF2 of 10.7 and an EER2 of 13.0 , this multi-zone heat pump perfectly meets modern energy saving requirements while ensuring balanced performance, summer and winter. With the support of our AirGreen team, we have already assisted several homeowners throughout the greater Montreal area, offering them the appropriate heat pump installation and HVAC maintenance to extend the life of their equipment.

Energy efficiency and technical characteristics

  • Heating capacity down to -30°C : Users of the MIDEA28 dual-head heat pump can expect stable heat output even during the region's typical cold spells. We have completed installations in Laval and on the South Shore where the temperature dropped below -25°C. In these situations, the MIDEA28 continued to provide sufficient heating, eliminating the need for a backup system.

  • 36,000 BTU Compressor : This compressor power was designed to easily support two indoor units (2 zones). In other words, it is ideal for larger spaces or to separate, for example, the living area from the sleeping area. We installed this heat pump in a triplex in Longueuil where each floor benefited from precise heat and air conditioning distribution.

  • R-454B Refrigerant : The transition to more environmentally friendly refrigerants is a key issue in the industry. With R-454B, this heat pump reduces its environmental impact and complies with current Quebec standards.

  • Warranty : The manufacturer offers an extended warranty (12 years on the compressor, 12 years on parts, and 10 years on labor). At AirGreen, we even offer an additional 10-10-10 warranty already included, to ensure maximum peace of mind for homeowners.

  • Provincial Grant (LogisVert): $3,600 : Updated as of May 1, 2025, this provincial grant can significantly reduce your total purchase and installation costs. Our team will provide you with information on eligibility criteria and administrative support.

Heat pump installation: the essential steps

  1. Building Analysis : Before any project, at AirGreen, we conduct a needs assessment. We consider the square footage, insulation, room layout, and the type of HVAC system already in place. For example, in a 1,500-square-foot residence in Boucherville, we found that a dual-head indoor unit configuration (one on the ground floor and one upstairs) was ideal for balancing heating and cooling.

  2. Choosing indoor locations : The MIDEA28 dual-head heat pump has the advantage of adapting to various types of wall-mounted or console units. Depending on room occupancy, we position the wall-mounted units to optimize air distribution. We also check the length of the ducts and the proximity of each head to minimize efficiency losses.

  3. Outdoor Unit Installation : With a size of 38.5 in x 16.38 in x 38.38 in and a noise level of 65 dB(A), the outdoor unit remains relatively compact and discreet. We take care to position it on a solid base, protected from snow and bad weather. For regions like the North Shore , where snow accumulation can be significant, we recommend a raised base or a suitable canopy.

  4. Connection and configuration : The step of connecting the refrigeration lines and the electrical wiring must be carried out by professional refrigeration engineers . At AirGreen, we scrupulously follow the manufacturer's recommendations for HVAC installation . We then use diagnostic tools to check that there are no leaks and that the refrigeration circuit is properly vacuumed.

  5. Commissioning and Calibration : Once the installation is complete, we conduct operational tests to calibrate the temperature, verify airflows, and evaluate overall performance. We then explain to the occupants how to use the thermostat, adjust the fan speed, or schedule the system, if applicable.

Tailor-made comfort thanks to two zones

With its two indoor units, the MIDEA28 dual-head heat pump offers individualized control. This means each occupant can enjoy a different temperature depending on the zone they are in. Here are some concrete benefits:

  • Reduced temperature conflicts : A family in Saint-Léonard wanted a cooler living area on the ground floor, while the master bedroom required a little extra heat at night. The MIDEA28 allowed two different temperature settings to be configured, satisfying all preferences.

  • Energy Consumption Optimization : In both air conditioning and heating mode, Midea's inverter technology adjusts compressor speed in real time. When only one zone requires modulation, the system can reduce its consumption. Similarly, if the other zone doesn't need additional cooling or heating, the heat pump operates at partial load, resulting in savings.

  • Uniformity of comfort : With adjustable fan speeds, each indoor unit can distribute air evenly. In a South Shore home, we observed more stable overall comfort compared to a single-zone heat pump. This balanced distribution had a positive impact on the quality of life in the home.

Testimonials and feedback

For several years, we have supported owners in Montreal , Laval , Longueuil , as well as the North Shore and the South Shore . Recent examples include:

  • Installation in a single-family home in Laval : The owner had a finished basement where the temperature was constantly cool. Thanks to one of the indoor heads dedicated to the basement, he was able to ensure consistent comfort, even when the ground floor already had a suitable temperature.

  • Renovation project in Longueuil : In a duplex, the MIDEA28 dual-head heat pump was installed to serve two independent units. In winter, the tenants appreciated the responsiveness of the heating, and in summer, they benefited from efficient air conditioning. We received positive feedback: the electricity bill was more stable, and total consumption decreased.

HVAC Maintenance and Sustainability

Like any other HVAC equipment, the MIDEA28 dual-head heat pump requires periodic maintenance to maintain its efficiency. Recommended interventions include:

  • Cleaning the interior filters : A clogged filter can reduce airflow and increase energy consumption. We suggest monthly cleaning, especially in environments where the air may contain more dust.

  • Annual inspection of the refrigeration circuit : Seals and connections must be checked to prevent any R-454B gas leaks. Low refrigerant levels can reduce the efficiency of the heat pump and, ultimately, damage the compressor.

  • Heating Defrost Check : A heat pump operating at sub-zero temperatures requires proper defrosting to prevent frost buildup on the outdoor unit. We ensure the defrost cycle is working properly, especially in regions with varying climates, such as the North Shore .

  • Complete diagnostics by a professional : At AirGreen, our technicians are trained to quickly detect any anomalies and extend the life of your unit. We offer a complete HVAC maintenance service, including electrical inspection, airflow monitoring, and heat pump calibration.

AirGreen's Practical Tips for Maximum Performance

  • Positioning indoor units : Avoid obstructing the air outlet with furniture or curtains. Overly restricted airflow can cause uneven comfort zones.

  • Smart Programming : The Wi-Fi option (optional on this model) allows remote control via an app. Some users take advantage of this feature to lower the temperature at night or during extended absences.

  • Building insulation : Even though the MIDEA28 dual-head heat pump is efficient, good insulation of the walls and roof remains the best way to retain heat or coolness.

  • Exterior Cleaning : Clear the outdoor unit of leaves, dust, or snow. Sufficient clearance ensures optimal air exchange.
