Outdoor unit
One compressor for the whole house. It supplies up to 4 heads and modulates from 8,400 to 23,600 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 heat pump designed for Quebec's climatic realities
At AirGreen Heat Pumps, Air Conditioning & Heating , we have been installing multi-zone systems for many years in a wide variety of settings: single-family homes in Laval , renovated duplexes in Montreal , new condos on the South Shore , and multigenerational residences on the North Shore . The ELIOS E-MULTI 4-head heat pump with a 27,000 BTU compressor perfectly fits this reality: offering precise, reliable, and efficient temperature control in several distinct zones, all from a single outdoor unit.
This model was designed to meet the specific needs of Quebec buildings: harsh winters, significant temperature variations, outdoor space constraints and high requirements for indoor comfort.
A truly flexible multi-zone solution for 4 distinct spaces
The ELIOS E-MULTI's quad-zone configuration allows for up to four independent indoor units , each selectable according to the room it serves: bedroom, living room, office, basement, or open-concept space. In our projects in Laval and Longueuil , we frequently combine different formats to optimize air distribution and architectural integration.
-
EMC wall units from 6,000 to 24,000 BTU
-
Ducted units for ceilings or false ceilings
-
4-way cassettes for central spaces
-
1-channel cassettes or consoles depending on the configuration
Each zone is controlled separately, allowing the temperature to be precisely adjusted according to the actual occupancy of the rooms. This approach reduces unnecessary energy consumption and improves daily comfort, particularly in homes where habits vary from one floor to another.
Heating performance down to -25°C: an essential criterion in Quebec
One point we systematically analyze at AirGreen when selecting a heat pump is its actual heating capacity in cold weather . The EXHSA2742AV1 outdoor unit maintains stable performance down to -25°C , a crucial threshold for winters in Montreal , Laval , and the Montérégie region.
Key technical data for heating:
-
Rated power: 27,000 BTU
-
Power at −8 °C: 18,000 BTU
-
Power at −15 °C: 19,000 BTU
-
Coefficient of performance ( COP ) at −8 °C: 12.03
In several residences on the North Shore , this model has made it possible to significantly reduce the use of supplementary electric systems, while maintaining a homogeneous temperature throughout the building.
Energy efficiency and LogisVert subsidy
The ELIOS E-MULTI 27,000 BTU stands out with efficiency ratings that exceed current standards:
-
SEER2 : 23.0+
-
HSPF2 : 19.5
-
EER2 : 11.2
These performance levels explain its eligibility for the $2,160 LogisVert provincial grant , a financial benefit we systematically include in our estimates for clients in Laval , Montreal , and the surrounding areas. At AirGreen, we guide our clients in understanding the technical criteria to avoid grant rejections or delays.
R-454B refrigerant: increased efficiency and safety
The choice of R-454B gas represents a significant evolution compared to older refrigerants. It offers:
-
a reduced global warming potential
-
improved thermodynamic efficiency
-
increased compliance with current environmental standards
The system also incorporates leak detection mechanisms , including automatic compressor shutdown and refrigerant circuit closure. During our installations in dense residential environments, particularly in condominiums in Montreal , these devices are essential to ensure occupant safety.
Controlled acoustic comfort both inside and outside
Comfort isn't just about temperature. Noise levels play a major role, especially in bedrooms and living areas. Depending on the configuration, the ELIOS E-MULTI indoor units can achieve noise levels as low as 20 dB(A) , which is particularly appreciated in residential projects in Laval-des-Rapides and Chomedey .
Outside, the unit displays a noise level of approximately 61 dB(A) , a parameter that we take into account when positioning in order to respect the neighborhood and municipal regulations.
HVAC installation: the AirGreen approach
Installing a multi-zone heat pump is not simply a matter of connecting units. At AirGreen, each project begins with a detailed analysis of the thermal loads , the electrical configuration (220 V, MCA , MOP 25 A ) and the architectural constraints.
In a recent project in Laval , we adapted the refrigeration system layout to preserve the exterior aesthetics while respecting maximum pipe lengths. This type of technical decision directly influences the system's durability and efficiency.
Common mistakes that we systematically avoid:
-
compressor oversizing
-
poor distribution of capacities between areas
-
absence of precise calculation of airflow ( CFM )
-
neglect of vibrations and support for the outdoor unit
Guarantee and peace of mind
The standard 10-year warranty on the compressor and parts reflects the system's reliability. An extended warranty can be added as needed, particularly for multi-unit residential projects or homeowners seeking extra protection.
Our role does not stop at installation: we also provide monitoring, HVAC maintenance and optimization of seasonal settings to preserve long-term performance.

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: 23,600 BTU/h at −8 °C, 19,000 at −15 °C.
How many heads can I connect?
Up to 4 on this outdoor unit. This product is configured for 4 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 8 combinations, from 6+6+6+6 to 9+9+9+9 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$2,832 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 3799027. 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, 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 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.
