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 realities of Laval and Greater Montreal
In the residential areas of Laval , Montreal , Longueuil , the North Shore , and the South Shore , we often encounter the same challenge: providing precise comfort in multiple rooms without increasing the number of outdoor units or compromising the building's aesthetics. The ELIOS E-MULTI 3-head heat pump with a 36,000 BTU compressor was specifically designed to meet this type of need.
At AirGreen , we regularly install this multi-zone system in single-family homes, renovated duplexes, and medium-sized condos. Its design allows it to power up to three independent zones , while maintaining excellent energy performance, even during the harsh winters typical of Quebec.
Why choose an ELIOS E-MULTI 36,000 BTU multi-zone heat pump?
One single outdoor unit, multiple controlled zones
The EXHSA3652AV1 outdoor unit can supply up to five zones , although this configuration is optimized for three indoor units . This flexibility is a major advantage for scalable projects: several customers in Laval are currently planning for three zones, while retaining the option to add more later without changing the compressor.
Stable comfort down to -25°C
In real-world conditions, this ELIOS heat pump maintains reliable heating capacity down to -25°C , with still very usable power at -15°C and -8°C. In our installations on the North Shore , particularly in Blainville and Boisbriand, this is crucial for ensuring primary heating without relying on a backup system.
R-454B refrigerant: efficiency and compliance
Choosing R-454B refrigerant meets current environmental standards while improving the system's overall efficiency. For homeowners concerned about long-term performance and regulatory compliance, this is a compelling argument.
Energy performance and key technical data
Capabilities and performance
The ELIOS E-MULTI 36,000 BTU heat pump boasts very solid performance indicators for a multi-zone configuration:
-
Cooling capacity : 36,000 BTU
-
Heating capacity at -8°C : approximately 27,000 BTU
-
High SEER2 rating , allowing for efficient air conditioning during the hot and humid summers of Montreal and Longueuil
-
High-performance HSPF2 , contributing to real savings on heating bills
In several projects carried out by AirGreen, particularly in multi-level houses in Laval-Ouest , these performances translate into controlled electricity consumption, even when several zones operate simultaneously.
Controlled noise level
-
Indoor unit : up to 20 dB(A) depending on the model chosen
-
Outdoor unit : approximately 63 dB(A)
This allows for discreet installation, including in dense residential areas where noise is a real concern.
Choice of interior units: true freedom of layout
One of the strengths of the ELIOS E-MULTI system lies in the variety of compatible units:
-
Wall-mounted units from 6,000 to 24,000 BTU
-
Ducted units for a more invisible integration
-
4-way cassettes for suspended ceilings
-
Single-channel cassettes or consoles depending on the room configuration
At AirGreen, we systematically adapt the type of unit to the actual use of the room: bedroom, living room, home office, or open space. In Longueuil , for example, a client opted for two quiet wall-mounted units in the bedrooms and a 4-way cassette unit in the main living area, while sticking with a single outdoor compressor.
HVAC installation: what we systematically check
A successful multi-zone HVAC installation relies on several critical points:
Precise sizing
A 36,000 BTU compressor must be intelligently distributed between zones. We avoid unbalanced combinations that could compromise comfort or the system's longevity.
Electrical management
-
Voltage : 220 V
-
MOP : 35 A
Our teams ensure that the electrical panel and circuit protection are perfectly suited, which is particularly important in older Montreal homes.
Positioning of the outdoor unit
In Laval and on the South Shore , we favour locations that facilitate maintenance, reduce vibration transmission and respect the clearances required for optimal operation in winter.
LogisVert subsidy: a concrete financial advantage
At the time of writing, this model is eligible for a $3,240 LogisVert provincial grant . For many clients, this assistance significantly reduces the net cost of the project and accelerates the decision to replace an old electric or oil heating system.
At AirGreen, we assist our clients in preparing documents and verifying eligibility, in order to avoid common errors that delay the payment of the subsidy.
AirGreen feedback from the field
In a recent project in Laval-des-Rapides , a two-story house suffered from significant temperature variations between the basement, ground floor, and upper floor. After installing an ELIOS E-MULTI 3-head heat pump , each level is now independently controlled. The client particularly appreciated the stable heating during periods of intense cold and the reduced noise compared to their previous system.
Another case on the South Shore , in a recently renovated semi-detached house, highlighted the flexibility of the system: the owners initially installed three zones, with the real possibility of adding a fourth during a future expansion.
Guarantee and peace of mind
The standard configuration includes a 10-year warranty on the compressor and parts , with additional options available depending on the project. While labor is not included by default, AirGreen offers tailored solutions to extend coverage and protect your investment over the long term.

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 3 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 26 combinations, from 6+6+6 to 12+18+18 (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.
