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 have been installing multi-zone HVAC systems for many years in a wide variety of settings: single-family homes in Laval, duplexes in Montreal, condos in Longueuil, semi-detached homes on the North Shore , and newer buildings on the South Shore . The ELIOS E-MULTI 5-head heat pump with a 36,000 BTU compressor is one of the configurations we recommend when several zones need to be heated and cooled independently, without requiring multiple outdoor units.
This type of system meets a specific need: to offer personalized comfort per room , while respecting the space, noise and energy efficiency constraints specific to the Quebec climate.
Why choose an ELIOS E-MULTI 36,000 BTU multi-zone heat pump in Laval?
A capacity adapted to the typical buildings of Laval and the surrounding area
With a cooling capacity of 36,000 BTU and efficient operation down to -25°C in heating mode , this heat pump is perfectly suited to the climatic conditions of Laval , Montreal , and the Montérégie region. In practical terms, this means:
-
Stable heating even during winter cold spells
-
Consistent air conditioning during periods of hot and humid weather
-
Sufficient capacity to serve up to 5 separate areas
We've installed it in multi-story homes where needs vary greatly between the basement, ground floor, and upstairs bedrooms. The result is consistent: each occupant can regulate their own zone without compromise.
A truly flexible multi-zone system
The ELIOS E-MULTI series allows you to combine several types of indoor units depending on the building configuration:
-
Wall-mounted units from 6,000 to 24,000 BTU
-
Ducted units for more discreet distribution
-
4-way cassettes for suspended ceilings
-
Single-channel cassettes or consoles depending on the layout
This flexibility is especially useful in renovations in Laval or Longueuil , where some rooms don't allow for the installation of a traditional wall unit. At AirGreen, we always analyze the room layout before proposing the most logical solution.
Energy efficiency and operation in cold climates
Measured yield, not theoretical
The ELIOS E-MULTI 36,000 BTU heat pump offers high energy efficiency:
-
SEER2 up to 23.1 in air conditioning
-
High HSPF2 , optimized for seasonal heating
-
A COP of 12.03 at -8°C , a concrete indicator of performance in real-world conditions.
In our facilities on the North Shore , these figures translate into a measurable reduction in electricity consumption compared to traditional electrical systems or older heat pumps.
R-454B refrigerant: a choice aligned with current standards
The R-454B gas used by ELIOS is known for:
-
Reduced global warming potential
-
Compliance with current environmental standards
-
Stable thermal efficiency over a wide temperature range
We observe in the field that this refrigerant contributes to a more regular operation of the system, particularly during winter defrost cycles.
Acoustic comfort: an often underestimated point
In the densely populated residential areas of Montreal and Laval , noise is a key factor. The ELIOS E-MULTI 36,000 BTU outdoor unit has a noise level of approximately 63 dB(A) , which is considered acceptable for its class.
Indoors, depending on the model, some wall units can operate at as low as 20 dB(A) in silent mode. We have installed this system in master bedrooms and home offices without any negative feedback regarding noise level.
HVAC installation: what the AirGreen experience changes in concrete terms
Actual study of thermal loads
A common mistake is choosing a multi-zone system based solely on the number of rooms. At AirGreen , every project begins with:
-
An analysis of the surfaces
-
The building's orientation
-
The existing insulation
-
Occupational habits
This approach allows us to fully utilize the nominal power of 36,000 BTU , without unnecessary oversizing.
Electrical management and compliance
The EXHSA3652AV1 compressor operates on a 220V power supply, with:
-
MOP: 35 A
-
MCA compliant with current standards
Our teams ensure that the existing electrical panel can support the load, which avoids surprises after installation.
Concrete examples of AirGreen installations
Intergenerational housing in Laval
In an intergenerational residence, we installed an ELIOS E-MULTI 5-zone system combining:
-
3 wall units
-
1 ducted unit for the floor
-
1 cassette for the common area
Result: each generation manages its temperature, without conflict, with lower electricity consumption than the old central system.
Renovated plex in Montreal
In a renovated duplex, where outdoor space was limited, the choice of a single multi-zone compressor allowed for:
-
To comply with municipal regulations
-
To free up rear space
-
To improve the rental value of the building
LogisVert subsidy: a concrete financial advantage
At the time of writing, this heat pump is eligible for a LogisVert provincial grant of up to $3,240 . We consistently assist our clients in Laval , Longueuil , and the South Shore with:
-
Validation of eligibility
-
Document preparation
-
The filing of the application
This step is often overlooked, even though it can significantly reduce the final cost of the project.
Maintenance and durability of the system
A well-maintained multi-zone system retains its performance over the long term. We recommend:
-
An annual HVAC service
-
Cleaning the filters at the change of seasons
-
Periodic checks of refrigeration connections
At AirGreen, we have seen ELIOS systems operate stably for several years without significant loss of performance when properly maintained.
Guarantee and peace of mind
The ELIOS E-MULTI 36,000 BTU heat pump is covered by:
-
10 years on the compressor
-
10-year warranty on parts
-
Optional labor warranty available
We always clearly explain the warranty conditions before installation, in order to avoid any long-term ambiguity.

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 5 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 15 combinations, from 6+6+6+6+6 to 9+9+9+9+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.
