A scalable and efficient solution for multi-zone comfort

At AirGreen , we offer the MIDEA28 2-Zone heat pump to meet the needs of homeowners who want a versatile and efficient HVAC (heating, ventilation and air conditioning) system. With its 27,000 BTU compressor , this unit is specially designed to serve two separate zones, providing comfort adapted to multiple rooms or floors of a property. With a proven heating capacity down to -30°C , the MIDEA28 stands out as a reliable heat pump, even in harsh Quebec winters. Below, we discuss its features, benefits and our concrete feedback in the greater Montreal area, Laval , Longueuil , as well as on the North Shore and South Shore .

Exceptional reliability even below -30°C

One of the MIDEA28 2-Zone heat pump 's major strengths is its ability to maintain high performance when temperatures drop. Equipped with Extreme Heat Inverter technology, it remains operational down to -30°C, which is essential for our Canadian winters. Families on the South Shore or in Montreal can thus maintain a comfortable indoor temperature throughout the year, without having to resort to expensive auxiliary heating.

Furthermore, the design of this heat pump incorporates a more environmentally friendly refrigerant, R-454B , which has a reduced global warming potential compared to older refrigerant gases. Thus, the MIDEA28 meets both sustainability requirements and the need for safe and efficient heating.

How Dual Zone Works: A Practical Overview

The MIDEA28 2-Zone heat pump can power two indoor units, each of which can be installed in a different room or floor. This means you can set separate temperatures in different parts of the house. For example, if you want to heat the ground floor more intensely while keeping the upper floor slightly cooler, the MIDEA28 manages these settings independently.

This multi-zone design is particularly useful in properties in Longueuil or the North Shore , where the architectural configuration often includes two floors or a basement. Rather than heating or cooling the entire property uniformly, you can target your actual needs, thus improving overall comfort and reducing energy consumption.

HVAC installation: AirGreen expertise

Our team at AirGreen has extensive experience in HVAC installation and maintenance of heat pumps and air conditioning systems. Installation steps for the MIDEA28 2-Zone heat pump include:

1. On-site assessment : First, we conduct a visit to confirm the best configuration for your space. We analyze the layout of the rooms, the possible placement of the indoor units, and accessibility for the outdoor unit.

2. Choice of indoor units : Depending on the size of the rooms and the level of insulation, we recommend wall-mounted units, mini-consoles or fan coils to precisely meet your comfort requirements.

3. Outdoor Unit Installation : With exterior dimensions of 37.25 x 16.13 x 31.88 in, the MIDEA28 outdoor unit can easily fit into many outdoor spaces or on a balcony, provided the recommended clearances are respected.

4. Connection and commissioning : We then connect the R-454B refrigerant lines and finalize the electrical connections (220V). A complete test is performed to ensure compressor performance, check noise levels, and calibrate the heat pump.

Our expertise ensures fast and reliable installation, minimizing disruptions to your daily life. We also take the time to explain the device's settings, including the option of integrating a Wi-Fi module to control the heat pump from a smartphone.

HVAC Maintenance: Extending the Life of the MIDEA28

Regular HVAC maintenance is essential to maintain the efficiency of your heat pump throughout the seasons. Here are some tips and services we offer:

• Cleaning Filters : Indoor unit filters should be cleaned or replaced periodically to ensure good air quality and maintain optimal flow.

• Coil Inspection : The coils in the outdoor unit can accumulate dust or debris. Annual cleaning extends compressor life and improves efficiency.

• Checking the refrigerant charge : With the new R-454B , it is crucial to maintain the correct pressure to avoid performance losses or possible overheating problems.

• General Operation Check : Our technicians examine fan speed, automatic regulation between heating and cooling mode, and behavior in multi-zone mode to ensure even temperature distribution.

Annual or biannual preventative maintenance helps detect minor problems early before they become costly breakdowns. Additionally, a well-maintained system uses less energy, resulting in long-term savings.

Customer testimonial: a successful installation in Montreal

We recently installed a MIDEA28 2-Zone heat pump in a duplex on Saint-Hubert Street in Montreal . The client wanted to independently heat and cool the ground floor and upper floor, while reducing their energy bill.

After evaluating the insulation and existing layout, we suggested two wall-mounted indoor units, one in the main living area and the other in the upstairs bedroom. From the first winter season, the owner noticed a significant improvement in comfort and a reduction of approximately 15% in electricity consumption, thanks to the MIDEA28's high SEER2 (23.0) and HSPF2 of 10.5.

Using the multi-zone mode, he adjusted the temperature so that the upper floor remained slightly cooler at night, allowing him to save even more money. As for the air conditioning mode, the customer highlighted the compressor's responsiveness, which allows rooms to be cooled quickly during heat waves.

Example on the South Shore: a two-level condo

Another client, located in Boucherville on the South Shore , called on AirGreen to equip his two-level condo with a reliable and quiet heat pump. Since it was a relatively compact space, the noise level of 61.0 dB(A) in outdoor mode was a decisive argument.

After installation, the customer found they could maintain approximately 22°C on the upper level and nearly 20°C on the lower level, all with a single outdoor unit and two indoor units. Acoustic comfort was found to be excellent, and the heat pump operates in extreme weather conditions without any noticeable performance loss.

Economic and environmental benefits

• Energy Efficiency : With a SEER2 of 23.0 , the MIDEA28 2-Zone heat pump uses less energy than a standard heat pump. On an annual basis, this efficiency translates into substantial savings.

• Provincial grants : The LogisVert grant of $3,000 (updated to May 1, 2025) represents significant financial support for those wishing to invest in an ecological and efficient system.

• Precise temperature control : The multi-zone principle allows you to heat or cool only occupied spaces, thus reducing waste.

• Reduced carbon footprint : Choosing a heat pump over a traditional heating system significantly reduces the use of fossil fuels and helps reduce greenhouse gas emissions.

Evolution and customization options

Although designed for two zones, the MIDEA28 2-Zone heat pump can be expanded to four zones by adding additional indoor units (models MSEHU-H06B-2A, MSEHU-H09B-2A, MSEHU-H12B-2A or MSEHU-H18B-2A, for example). This allows the system to be adjusted to future changes in your home: basement conversion, addition of an extension, etc.

For those who want even more advanced control, the Wi-Fi option makes it easy to remotely manage temperature and schedule time. For example, you can set up automatic cooling before you arrive home or lower the temperature when you're away.

Proactive maintenance: avoiding unplanned breakdowns

Our experience at AirGreen shows that regular preventative maintenance is key to extending the life of a heat pump. Beyond simply replacing filters, we recommend scheduling an inspection before each heating or cooling season.

During this visit, we carry out specific tests:

• Checking valves and connections : Detect any micro-leaks of R-454B refrigerant.

• Heat exchanger test : Ensure there is no evidence of oxidation or premature corrosion.

• Electronic Check : Review the operation of the control module, multi-zone mode and electrical panel.

This approach avoids sudden service interruptions and ensures that your HVAC system remains optimal throughout the year.
