Outdoor unit
One compressor for the whole house. It supplies up to 6 heads and modulates from 13,000 to 45,000 BTU/h depending on what the rooms call for (NEEP).
Base pan heater
A heater keeps the outdoor unit’s base pan free of ice below 1 °C and during defrost (NEEP).
Refrigerant lines
One pair of lines per head.
Indoor heads
One head per room, each with its own remote and temperature. The combination is chosen in the “Zones” menu.
Control
Each zone is set separately.
Turn rooms on and off. Watch the power being shared.
One outdoor unit supplies every head: when several rooms call at once, they share its capacity. Pick an outdoor temperature.
Tell us your rooms. We tell you if this size is enough.
Pick the number of rooms and their size. The estimate targets a −15 °C day; it is a guide, the real calculation is done room by room at your home.

A powerful and flexible dual-zone heat pump, perfectly adapted to the climatic realities of Quebec
At AirGreen, we know how much the thermal comfort of a home or business premises depends on the ability of an HVAC system to effectively manage Quebec's extreme climatic variations. That's why we offer solutions like the MIDEA28 2-Zone heat pump , a dual-zone unit with a 48,000 BTU compressor, compatible with several types of indoor units, ideal for heating or cooling two separate rooms with precision .
Thanks to its advanced inverter technology , its multi-type compatibility (wall, cassette, console, ducted), its ecological R-454B refrigerant and its guaranteed performance down to -30°C , this heat pump represents a long-term investment for residences, condos or businesses in Montreal, Laval, the South Shore and the North Shore .
A high-performance compressor designed for the Quebec climate
The heart of this heat pump is its MIDEA MO6HX-H48B-2A outdoor unit, capable of managing up to 6 zones , although it is optimized here for two zones (dual zone) . This Energy Star® Cold Climate certified compressor ensures consistent performance, even during harsh winters.
Key specifications:
-
Heating capacity: -30°C
-
Cooling power: 48,000 BTU
-
SEER2: 23.0
-
HSPF2: 11.0
-
EER2: 12.0
-
Exterior noise level: 65 dB(A)
-
Refrigerant: R-454B , more environmentally friendly
This level of energy efficiency not only reduces your electricity bills , but also makes you eligible for the LogisVert grant of $5,280 (updated May 2025).
2-zone configuration: a system adapted to your real needs
The dual-zone system allows you to connect two independent indoor units to a single compressor. This modularity offers individual control in each zone , allowing you to adapt the temperature according to occupancy, room function or individual preferences.
Examples of possible combinations:
-
Living room + master bedroom (e.g. 18,000 + 30,000 BTU)
-
Office + family room
-
4 1/2 apartment: living room + open kitchen
The wide variety of compatible indoor units (wall-mounted, cassettes, ducted, floor consoles) allows you to customize the installation to each residential or commercial configuration .
Why choose a model compatible with R-454B?
R-454B refrigerant gas has been designed to meet new environmental standards without compromising performance. It features:
-
Low global warming potential (GWP) compared to R-410A
-
Better energy efficiency
-
Regulatory sustainability assured over the long term
As a responsible HVAC player, AirGreen favors models that anticipate new refrigerant laws while offering superior performance.
Exceptional installation flexibility
Thanks to its multi-compatible system , the MIDEA28 accepts several models of indoor units:
-
MSEHU-H06B to H36B (wall-mounted)
-
MFAHU and MFBHU (floor console, ceiling/floor)
-
MACHU or MDHHU (gainable)
-
Single-track and four-track cassette (MCAHU, MCDHU)
This flexibility allows:
-
A discreet installation , without altering the interior design
-
Better air distribution , adapted to the specific characteristics of each room
-
A hybrid system (ducted + wall-mounted) if desired

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 2 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 11 combinations, from 6+24 to 33+33 (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; 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.
