Outdoor unit
One compressor for the whole house. It supplies up to 5 heads and modulates from 10,000 to 31,000 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.

A multi-zone solution designed for the residential and multi-unit realities of Greater Montreal
At AirGreen, we've been installing HVAC systems long enough to know that a multi-zone product is never chosen by chance. It's almost always the result of a very specific context: multi-story houses with very different thermal zones, renovated duplexes in Laval, condos without existing ductwork, or residences where precise room-by-room control is desired without multiplying the number of outdoor units.
The ELIOS E-MULTI 4-head heat pump with a 36,000 BTU compressor perfectly meets this type of need. It can supply up to four independent zones from a single high-performance outdoor unit, designed to operate efficiently down to -25°C , a non-negotiable requirement for the climate of Laval, Montreal, the North Shore and the South Shore .
In several recent projects completed by our team, including single-family homes in Laval-des-Rapides and rental buildings in Duvernay, this model has proven itself for its stability in winter heating, its configuration flexibility and its excellent energy performance eligible for the LogisVert subsidy .
A truly flexible multi-zone architecture
One compressor, multiple comfort realities
The heart of the system lies in the EXHSA3652AV1 outdoor unit, a 36,000 BTU compressor capable of powering several types of indoor units: wall-mounted, 4-way cassette, console, or ducted units. This flexibility is essential in real-world situations. Very often, a single home presents a variety of challenges: an open-plan living room, closed bedrooms, a more humid basement, or an upper floor facing due south.
With this system, each zone is managed independently:
-
target temperature per room
-
simultaneous operation in heating or air conditioning
-
adjusting the airflow according to actual usage
This not only allows for greater comfort , but also a concrete reduction in energy consumption , since only occupied areas are used.
Actual heating capacity in cold weather
One point we always check when analyzing a project is the power available in real winter conditions , and not just the nominal value.
Based on this model:
-
36,000 BTU nominal
-
27,000 BTU at -8°C
-
26,000 BTU at -15°C
-
guaranteed operation down to -25°C
In installations carried out in Laval and on the North Shore , we have observed excellent thermal stability even during prolonged periods of cold, where less well-sized systems begin to lose efficiency or require supplementary heating.
Energy efficiency and compliance with Quebec programs
Measurable performance and certifications
The ELIOS E-MULTI 36,000 BTU heat pump boasts efficiency values that clearly place it in the category of high-performance multi-zone systems:
-
ENERGY STAR®
-
ENERGY STAR® – cold climate
-
SEER2 up to 23.1
-
High HSPF2 for heating
-
COP of 12.03 at -8 °C
These performance levels allow access to the LogisVert subsidy , currently estimated at $3,240 for this model, a determining factor in the final decision of several clients in Laval and on the South Shore .
R-454B refrigerant: a choice aligned with the new standards
The system uses R-454B gas , a new-generation refrigerant with a reduced global warming potential , in line with current environmental guidelines. In practice, this also translates to:
-
improved pressure stability
-
increased thermal efficiency
-
integrated leak detection and safety devices
These elements are particularly important in multi-zone configurations, where several evaporators are connected to the same outdoor unit.
Choice of indoor units: true personalization
Extended compatibility according to building needs
Depending on the project configuration, we can integrate different models of compatible indoor units, including:
-
EWHMA06 / 09 / 12 / 18 / 24 / 33
-
Wall-mounted for enclosed rooms
-
4-way cassettes for open areas
-
Ducted units for discreet integration
In a recent project in a triplex in Laval, we combined two wall-mounted units in the bedrooms, a 4-way cassette in the living room, and a ducted unit for an office space, all powered by the same compressor. This type of configuration would be much more complex, if not impossible, with traditional systems.
Controlled acoustic comfort
One aspect often underestimated by customers, but immediately noticeable after installation, is the noise level :
-
Indoor units from 20 dB(A) depending on the model
-
outdoor unit at 63 dB(A)
In townhouses in Laval or terraced condos, this quietness makes a real difference in everyday life, especially at night.
HVAC installation: where AirGreen's expertise makes the difference
Multi-zone sizing and balancing
Installing a multi-zone heat pump is more than just connecting units. At AirGreen, every project begins with:
-
a detailed thermal analysis
-
calculating charges per room
-
validation of pipe lengths
-
strict adherence to MCA and MOP values (35A)
Improper balancing can lead to uneven performance, excessive energy consumption, or premature compressor wear. This is a mistake we regularly correct in installations carried out without prior analysis.
Concrete feedback from our customers
Across several installations carried out in Laval, Montreal and Boucherville , the feedback is consistent:
-
consistent comfort between floors
-
better humidity management in summer
-
significant reduction in energy bills
-
absence of noisy or unstable cycles in winter
These results are not theoretical: they come from real projects monitored by our after-sales service team.
Guarantee and sustainability of the system
The system is covered by:
-
10 years on the compressor
-
10-year warranty on parts
-
0 years on labor costs (option available)
We always clearly explain these elements before installation, as transparency is an integral part of our approach. An additional warranty on labor can be added depending on the project and the client's expectations.

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: 31,000 BTU/h at −8 °C, 26,000 at −15 °C.
How many heads can I connect?
Up to 5 on this outdoor unit. This product is configured for 4 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 28 combinations, from 6+6+6+6 to 12+12+12+12 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$3,720 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 3799030. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −25 °C.
Is it noisy?
Indoors, the reference head goes down to 20 dB(A). Outdoors, 63 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 10 years on the compressor and 10 years on parts; labour is not included by the manufacturer. AirGreen extended warranty: possible.
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.
