MO4HX-H27B-2A

Outdoor unit

One compressor for the whole house. It supplies up to 4 heads and modulates from 8,400 to 30,000 BTU/h depending on what the rooms call for (NEEP).

03 · How it works

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.

04 · My plan

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 grant you can calculate, not guess.

30,000 BTU/h÷ 1,000 ×$120=$3,600

The capacity at −8 °C comes from Hydro-Québec’s list of October 1, 2026. $120 per 1,000 BTU/h is the rate for ENERGY STAR cold-climate heat pumps (guide v1.10).

Set for this system (AHRI 215471460). Another head combination (ducted, console) can change the AHRI number, and so the amount.
Cap: the grant never exceeds 100 % of the purchase and installation cost before taxes.
9 months after installation to apply; +5 % when two measures are in the same request.

Everything we have written about this system.

An innovative tri-zone system for tailor-made comfort in all seasons

At AirGreen , we understand that optimal comfort requires intelligent temperature management in each room. That's why we offer the MIDEA28 3-Zone heat pump , a high-performance multi-zone system that allows you to individually regulate the temperature of three separate zones, while offering exceptional energy performance. Ideal for homes in Montreal , Laval , Longueuil , as well as on the North Shore and South Shore , this heat pump is designed to meet the rigors of Quebec's climate.

Technology adapted to the reality of the Quebec climate

The MIDEA28 is equipped with a 27,000 BTU compressor that runs on R-454B gas , a more environmentally friendly refrigerant than its predecessors, while maintaining high thermal performance. ENERGY STAR® certified , this unit ensures remarkable energy efficiency, with a SEER2 of 23.0 , an HSPF2 of 10.5 and an EER2 of 12.5 .

Heating down to -30°C

Designed to withstand harsh winters, the MIDEA28 heat pump operates down to -30°C , making it a trusted choice for our customers in Blainville , Brossard , Repentigny or Châteauguay . Its modulating inverter compressor adjusts power according to actual demand, resulting in reduced consumption and consistent comfort.

Unparalleled adaptability thanks to multiple zone configurations

Among the many possible configurations, we find:

  • 6+6+12 BTU for three small moderate zones

  • 9+9+9 BTU for three medium zones

  • 6+9+18 BTU for areas with varying thermal needs

This flexibility allows it to cover bedrooms, an open living room or a finished basement.

Main technical characteristics

  • Outdoor Model Number : MO4HX-H27B-2A

  • External dimensions : 37.25 x 16.13 x 31.88 in

  • Exterior noise level : 61 dB(A)

  • Voltage : 220V

  • Warranty : 12 years compressor, 12 years parts, 6 years labor (included, straight from the distributor)

  • WiFi Compatibility : Optional

An installation by AirGreen: expertise and peace of mind

At AirGreen , each project is treated with unparalleled attention to detail. When installing the MIDEA28 for a family in Saint-Lambert , we responded to a double constraint: ensuring comfort in a north-facing bedroom without windows, and in a living room bathed in afternoon sunlight. We proposed the 6+9+12 configuration , perfectly suited to this thermal distribution.

Our team installed the MSEHU-H06B-2A , MSEHU-H09B-2A and MSEHU-H12B-2A indoor units with aesthetic ducts and strategic positioning, ensuring even and quiet diffusion in each area. Customers expressed great satisfaction from the first weeks of use.

Attractive grants to reduce your costs

The MIDEA28 heat pump is eligible for a $3,000 LogisVert grant (updated May 1, 2025), representing substantial savings for energy-conscious and environmentally friendly homeowners.

Energy-efficient performance adapted to local realities

Consumers in Longueuil and Terrebonne want a system that consumes little energy and meets environmental regulations. R-454B gas , used by MIDEA, reduces the impact on the ozone layer and meets the strictest standards.

A multi-zone system, several types of indoor units

Depending on the comfort needs and the design of the home, the customer can choose:

  • Standard wall murals (MSEHU-HxxB-2A)

  • Floor consoles

  • Built-in units (1 or 4-way cassette)

  • Ducted units for integration into false ceilings

This compatibility allows for harmonious integration into all types of interiors , from modern condos to traditional single-family homes.

SynchroConnect: easy and secure installation

The SynchroConnect connection system allows for quick installation and prevents connection errors: the system automatically recognizes the connection ports of the indoor units. This feature reduces installation time and improves system reliability.

19 · Questions

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 3 heads.

Can I mix head sizes?

Yes. The “Zones” menu offers 15 combinations, from 6+6+6 to 12+12+12 (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. AirGreen extended warranty: included.
