A triple-zone heat pump suitable for the large spaces of Greater Montreal
At AirGreen, we know that a 3-Zone heat pump system must meet high performance standards to withstand our harsh winters and sometimes very hot summers. With the MIDEA28 3-Zone Heat Pump | Compressor: 48,000 BTU , we offer a complete HVAC solution for residential and commercial properties that require even distribution of heating and cooling across multiple rooms. With its SEER2 of 23.0 and HSPF2 of 11.0 , this unit is designed to deliver superior energy efficiency, while ensuring consistent comfort throughout the year.
Why Choose a Midea 48,000 BTU 3-Zone Heat Pump
The main strength of a multi-zone heat pump lies in its ability to serve multiple rooms or floors with a single outdoor compressor. The 48,000 BTU MIDEA28 offers three independent outputs (hence the 3-Zone designation), allowing for personalized temperature control. Here are the key points to consider:
-
Adapted to the Quebec climate : The module is ENERGY STAR® Cold Climate certified and operates efficiently down to -30°C . This feature is crucial for homeowners in Montreal, Laval, Longueuil, on the North Shore and the South Shore, where winters are long and cold.
-
R-454B gas : More environmentally friendly, this new-generation refrigerant reduces the impact on ozone and promotes better energy efficiency.
-
48,000 BTU Inverter Compressor : This high power is ideal for larger areas. At AirGreen, we regularly install these systems in two- or three-story homes, as well as medium-sized commercial buildings.
-
Flexible Multi-Zone Technology : While this configuration offers 3 indoor units, the Midea platform can support up to 6 zones, should your layout needs evolve.
-
Optional Wi-Fi : Occupants can manage the temperature of each zone via a user-friendly app. This feature facilitates daily energy management.

-
At AirGreen, we offer a 12-year warranty on the compressor and 12 years on parts , in addition to 6 years on labor , straight from the distributor. It is also possible to extend the labor warranty up to 10 years through the additional warranty option (10-10-10).
-
-
Compatibility with multiple types of indoor units
-
Wall-mounted evaporators (high, medium, or low static), ceiling-mounted units , or ducted units can be combined. This allows you to configure each zone according to the building's architecture and your aesthetic preferences.
-
Concrete examples of successful installations with the MIDEA28 heat pump
-
Triplex in Plateau-Mont-Royal : We installed a 48,000 BTU Midea heat pump in an older triplex where heat distribution was a challenge. Each unit now benefits from a dedicated zone, allowing occupants to regulate their temperature without encroaching on neighbors' energy consumption.
-
Bungalow in Laval : The basement was always too cool and the upper floor too hot. Thanks to a 3-zone system, the owners enjoy a perfect balance. As the seasons change, they notice a significant reduction in their energy costs.
-
Commercial space in Longueuil : A 1,500 sq. ft. office with enclosed spaces (conference rooms, private offices) and open areas (break room, reception). Triple zoning helped maintain a uniform temperature, despite varying needs depending on room occupancy.
AirGreen Installation Process and Quality Protocols
-
Analysis and sizing
-
Before each project, we send an experienced refrigeration engineer to assess the heat load and air volume. The data collected confirms that a 48,000 BTU configuration is adequate to optimally cover each zone.
-
-
Choice of indoor units
-
Depending on the room layout, we offer several options: wall-mounted, recessed ceiling, and mini-ducts. For a room with low or sloping ceilings, we generally recommend a wall-mounted unit . For a larger space, a cassette or ducted ceiling unit may be preferred, ensuring a discreet appearance and even air distribution.
-
-
Installation and commissioning
-
Our AirGreen teams coordinate the installation of the outdoor compressor, the routing of the refrigerant lines, the electrical connection and the fixing of the indoor units. The system is then evacuated to evacuate any residual moisture or air, then charged with the appropriate amount of R-454B .
-
After a thorough test in heating and cooling modes, we validate the pressure, temperature stability, and quiet operation. We also provide a detailed user guide and explain to the customer how to adjust each zone.
-
-
After-sales services and maintenance
-
A 3-zone heat pump requires periodic maintenance. We recommend annual professional cleaning of the compressor and indoor units. This includes checking the filters, coils, and condensation drain. AirGreen offers a convenient scheduled maintenance plan to ensure long-term performance.
-
Tips to maximize the efficiency of your MIDEA28 heat pump
-
Optimize air circulation : Keep air vents (or wall splits) clear of furniture or curtains. Impeded airflow reduces the overall performance of the system.
-
Insulate infrequently used areas : If you don't use certain rooms frequently (a guest room or office), adjust the temperature in that area to an eco-friendly level. This saves money without sacrificing overall comfort.
-
Use WiFi scheduling : The WiFi option allows you to manage the temperature of each zone via a mobile app. For example, you can schedule a temperature drop at night or during extended absences.
-
Schedule Regular Maintenance : Annual maintenance performed by our specialists maintains peak performance, extends the life of the device and helps ensure warranty coverage is respected.
Possible savings and access to subsidies
Thanks to the high efficiency (SEER2 23.0 / HSPF2 11.0) of the MIDEA28 3-Zone Heat Pump , many homeowners are seeing a 30 to 40% reduction in their annual heating and cooling bills. In addition, the Provincial Grant program (LogisVert) can reach $5,280 (updated May 1, 2025) to encourage the adoption of ENERGY STAR® certified equipment. Our AirGreen advisors can help you prepare the documents required to apply for a grant and optimize your investment.

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: 45,000 BTU/h at −8 °C, 47,000 at −15 °C and 24,600 at −30 °C.
How many heads can I connect?
Up to 6 on this outdoor unit. This product is configured for 3 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 9 combinations, from 6+18+18 to 18+18+18 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$5,400 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 3627492. 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 24,600 BTU/h with a COP of 1.27.
Is it noisy?
Indoors, the reference head goes down to 20 dB(A). Outdoors, 65 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. AirGreen extended warranty: included.
