A versatile air conditioning and heating solution for your property
In the field of HVAC (heating, ventilation and air conditioning), homeowners' needs vary considerably depending on the size of the home, room layout and comfort preferences. At AirGreen, we use our expertise to recommend efficient and durable systems. The MIDEA28 4-Zone heat pump | Compressor: 27,000 BTU stands out for its ability to serve up to four separate zones, all while offering remarkable energy efficiency and personalized comfort. Here is a detailed overview of this product, its benefits and how we install and maintain it in Montreal , Laval , Longueuil , on the North Shore and the South Shore .
How does the MIDEA28 4-Zone heat pump work?
The MIDEA28 4-Zone heat pump uses a 27,000 BTU compressor and R-454B refrigerant to provide both heating and cooling for multiple spaces. The multi-zone design allows for multiple indoor units (up to four) to be connected, each of which can be individually controlled to precisely adapt to each section of your building.
With a SEER2 of 23.0 and an HSPF2 of 10.5 , this heat pump uses less energy than many other systems on the market. Plus, it's ENERGY STAR® certified and suitable for cold climates down to -30°C in heating mode.

Thanks to its inverter control mode, the heat pump automatically modulates its power according to actual needs. Thus, when not all zones require the same level of air conditioning or heating, the machine adjusts its consumption accordingly.
Major benefits for owners in Montreal, Laval, Longueuil, North Shore and South Shore
Personalized temperature control
With the MIDEA28 multi-zone heat pump , you can optimize the comfort of each room. For example, a basement bedroom, a ground-floor living room, or an upstairs office do not all have the same sun exposure or insulation. The multi-zone system allows you to maintain a cooler temperature where you want it (living room, family room) and a slightly warmer temperature in the bedrooms, all without wasting energy by uniformly cooling or heating unoccupied rooms.
Reducing energy costs
By offering flexible control, the MIDEA28 4-Zone heat pump helps reduce overall energy consumption. You can precisely target the rooms that need heating or cooling , avoiding unnecessary heating of unoccupied spaces. The integration of inverter technology and R-454B refrigerant also ensures high efficiency. At our facilities in Montreal , Laval , and elsewhere, we have seen significant reductions in energy bills when homeowners upgrade to high-efficiency multi-zone systems.
Grants and financial aid
The MIDEA28 4-Zone heat pump is among the devices eligible for grant programs in the province. Currently, the provincial LogisVert grant offers up to $3,000 (updated May 1, 2025) for the installation of this type of high-efficiency heat pump . At AirGreen, we support our clients through the administrative procedures to maximize savings.
Flexible and quiet installation
The outdoor unit, measuring approximately 37.25 in x 16.13 in x 31.88 in , can easily fit into different types of layouts, whether it is a small backyard in an urban setting (Montreal, Longueuil) or a more spacious area (Laval, South Shore, North Shore). In addition, the noise level of only 61 dB(A) makes this heat pump discreet, both for the occupants and for the neighborhood. Indoors, each evaporator is designed to be compact and can be installed on the wall, in a ceiling cassette, or in a console, depending on the desired configuration.
Reliability and guarantee
Midea, renowned for the quality of its compressors, offers a 12-year warranty on the compressor, 12 years on parts, and 10 years on labor. At AirGreen, we also support our customers with reliable HVAC maintenance and after-sales service. This provides long-term peace of mind for all homeowners who invest in this heat pump .
HVAC Installation Process by AirGreen
Home assessment
Before installing a MIDEA28 4-Zone heat pump , we first perform a free on-site estimate to assess the home's layout. We identify the number of indoor units required, the length of the refrigerant pipes, the space available for the outdoor unit, and the specifics of the power supply (220 V). This step is crucial to properly size the unit and ensure optimal performance.
Multisplit planning and configuration
With the MIDEA28 multi-zone heat pump , there are several combinations of interior capacities (6,000, 9,000, 12,000, 18,000 BTU, etc.). Depending on your needs, we can install wall-mounted fan coils in some rooms and opt for a cassette or discreet mini-duct in others. For example, for an apartment divided into four main rooms, we recently opted for a 6+6+9+12 combination, guaranteeing ideal distribution and individualized comfort.
Installation and connection
Once the equipment has been selected, our experienced technicians proceed to install the pipes, assemble the outdoor unit, and install the indoor heads. We pay particular attention to the insulation of the pipes , the location of the condensate drain, and the refrigerant connection. The goal is to ensure stable refrigerant circulation and a perfect seal.
At AirGreen, we insist that everything is done in compliance with RBQ standards and manufacturer specifications. We don't require an initial deposit: you only pay once you're 100% satisfied with the result.
Verification and commissioning
Before finalizing, we perform a series of tests: pressure check, wiring inspection, thermostat calibration, etc. We also explain how to effectively control each zone (temperature setting, operating mode, possible programming). We believe that basic knowledge on the part of the owner is essential to get the most out of this HVAC system.
Customer testimonials and feedback
Over the years, at AirGreen, we have installed numerous 4-Zone MIDEA28 heat pumps in Montreal duplexes, single-family homes in Laval , and condos on the South Shore . Homeowners particularly highlight:
-
Significant reduction in electricity costs, especially in winter, thanks to stable heating power down to -30°C.
-
Tailor-made comfort , with the ability to keep one area warmer while other rooms remain cooler.
-
The silent system , well appreciated in dense residential areas.
-
The compactness and discreet appearance of the indoor units, which fit well with the existing decoration.
Some customers have also appreciated the flexibility of this multi-zone system for future upgrades. For example, a Longueuil homeowner who renovated his basement was able to easily connect a new indoor head to his existing outdoor unit, adding localized comfort without having to replace the entire HVAC system.
HVAC Maintenance and AirGreen Services

-
Cleaning the internal coils and filters.
-
Checking the pressure of R-454B refrigerant.

What people ask us about multi-zone systems.
Can I heat one room and cool another at the same time?
No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.
What happens when every room calls for heat?
They share the outdoor unit’s capacity: 30,000 BTU/h at −8 °C, 27,000 at −15 °C and 14,000 at −30 °C.
How many heads can I connect?
Up to 4 on this outdoor unit. This product is configured for 4 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 8 combinations, from 6+6+6+6 to 9+9+9+9 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$3,600 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.
Is it ENERGY STAR certified?
Yes, cold climate, ID 3627486. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −30 °C. At −30 °C, it still delivers 14,000 BTU/h with a COP of 1.26.
Is it noisy?
Indoors, the reference head goes down to 20 dB(A). Outdoors, 61 dB(A): we place the unit away from bedroom windows.
Why a multi-zone instead of several wall units?
One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.
What does the warranty cover?
Our sheet lists 12 years on the compressor and 12 years on parts; labour is not included by the manufacturer. AirGreen extended warranty: included.
A multi-zone system is planned room by room. At your home.
We measure every room, draw the line route and choose the right head for each zone. The on-site estimate is free and the quote arrives within 24 h.
