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 solution designed for residential and multi-unit dwellings in Laval and Greater Montreal
At AirGreen, we've been installing multi-zone HVAC systems for years in a wide variety of settings: single-family homes in Laval, multi-unit dwellings in Montreal, condominiums on the North Shore , and renovated residences on the South Shore . The ELIOS E-MULTI 3-head heat pump with a 27,000 BTU compressor is a perfect fit for these situations. It allows you to manage three independent zones from a single outdoor unit, while still offering the flexibility to expand to four zones depending on the configuration.
This model addresses a common problem we observe in the field: varying heating needs from room to room, combined with constraints related to outdoor space, noise, and performance during Quebec winters. With heating capacity maintained down to -25°C , this system ensures consistent comfort even during cold snaps, without systematically resorting to supplemental heating.
Understanding the E-MULTI 27,000 BTU configuration and its concrete advantages
Three independent zones, precise comfort control
The triple-zone configuration allows the EXHSA2742AV1 outdoor unit to be combined with different types of indoor units: wall-mounted, ducted, cassette, or console. Each zone has its own thermostat and operates according to the actual needs of the room. In practice, this means:
-
a room kept at a lower temperature at night;
-
a living room that is heated more consistently in the evening;
-
an air-conditioned office, occasionally during the day.
This independence limits unnecessary cycles, improves overall efficiency and helps to reduce annual electricity consumption.
Actual capacity and measured performance
With a cooling capacity of 27,000 BTU and a useful heating output of 18,000 BTU at -8°C , this system efficiently covers typical areas of multi-story homes or large condominiums. SEER2 , HSPF2 , and COP values demonstrate consistent seasonal performance that meets local climate requirements, making it suitable for installations eligible for energy efficiency programs.
In several projects carried out in Laval and Longueuil, we have observed a notable improvement in thermal stability compared to undersized dual-zone systems, often installed during quick renovations.
R-454B refrigerant: efficiency and environmental compliance
The choice of R-454B refrigerant is not insignificant. It offers a lower global warming potential than previous generations, while maintaining excellent thermodynamic properties. For our customers, this translates into:
-
increased compliance with current environmental standards;
-
improved durability of the installation;
-
easier integration into energy renovation projects.
HVAC installation: what the AirGreen experience changes in concrete terms
Sizing and selection of indoor units
One of the common pitfalls of multi-zone systems lies in an improper balance between indoor units and compressor capacity. At AirGreen, every project begins with a detailed analysis of thermal loads : room orientation, existing insulation, air volumes, and occupancy patterns.
We recently installed this ELIOS E-MULTI 27,000 BTU configuration in a duplex in Laval, where the ground floor required a discreet cassette unit, while the upper floor benefited from two quiet wall-mounted units. The result: even air distribution and an indoor sound level measured between 20 and 44.7 dB(A) depending on the mode, perfectly suited to living spaces.
Electrical constraints and safety
With a 220V power supply, a 25A MOP , and a suitable MCA , this heat pump integrates easily into most modern residential panels. Our teams systematically verify the circuit capacity, conductor gauge, and compliance with local standards before installation to prevent any overload or nuisance tripping.
Noise management and outdoor installation
The outdoor noise level of approximately 61 dB(A) is a key consideration in the densely populated areas of Montreal and Laval. We prioritize locations that minimize noise propagation: anti-vibration mounts, adequate clearances, and careful unit orientation. These details often make a difference in long-term satisfaction.
Energy efficiency and LogisVert subsidy
The ELIOS E-MULTI 3-head heat pump is ENERGY STAR® certified , including for cold climates, making it eligible for the $2,160 LogisVert provincial grant (updated November 26, 2025). For many customers on the North Shore and in the Montérégie region , this financial assistance allowed them to choose a more efficient multi-zone configuration rather than a less effective compromise.
At AirGreen, we support each client in preparing their file: validation of AHRI numbers, conformity of installed models and transmission of required documents.
Reliability, guarantees and after-sales service
The standard warranty covers 10 years on the compressor , 10 years on parts , and 0 years on labor , with additional warranty options available depending on the project context. Beyond the numbers, our added value lies in our follow-up: rapid diagnostics, readily available parts, and technicians specializing in HVAC maintenance and multi-zone heat pump repair .
In several interventions carried out after installation, we were able to optimize seasonal settings, correct airflow imbalances and extend the lifespan of the equipment.
Common mistakes to avoid with a multi-zone system
-
Undersize the compressor relative to the actual number of zones used.
-
Mixing indoor units that are unsuitable for the room sizes.
-
Neglecting the placement of the outdoor unit in noise-sensitive areas.
-
Neglecting annual HVAC maintenance, which is essential to maintaining the advertised yields.
These points are integrated from the design stage of each AirGreen project, in order to avoid costly corrections afterwards.

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 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?
$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.
