A multi-zone solution designed for the residential realities of Laval and Greater Montreal
At AirGreen, we have been installing multi-zone HVAC systems for many years in a wide variety of settings: new condos in Laval, multi-storey single-family homes on the North Shore , renovated plexes in Montreal , and intergenerational residences on the South Shore . The ELIOS E-MULTI 2-head heat pump with an 18,000 BTU compressor fits perfectly into this reality: offering stable, adjustable, and efficient comfort without the need for multiple outdoor units.
This model addresses a clear need that we often encounter in the field: heating and cooling two distinct zones with different uses (for example: main living area and bedrooms), while maintaining a clean, discreet installation that meets current energy requirements in Quebec.
Why the ELIOS E-MULTI system is particularly relevant in Laval
Laval has a very heterogeneous housing stock. It includes everything from 1970s houses with varying levels of insulation to recent constructions with high-performance building envelopes. In both cases, a well-designed multi-zone system helps avoid common mistakes: unnecessary overheating, short cycles, discomfort in certain rooms, or excessive electricity consumption.
With its 18,000 BTU compressor , the ELIOS E-MULTI system efficiently powers two indoor wall units , while maintaining a modulation reserve to adapt to the typical seasonal temperature variations of Laval , where winters can drop well below -20°C.
Efficient heating down to -25°C
A key point for our customers: actual heating capacity. This system is designed to operate efficiently down to -25°C , which corresponds to the winter conditions we regularly experience in the region. In practice, this means:
-
maintaining comfort without systematically resorting to supplementary heating,
-
thermal stability in remote areas,
-
reduction of complaints related to temperature variations between rooms.
In several installations carried out in Laval, we have found that this type of configuration makes it possible to advantageously replace electric baseboard heaters while significantly improving heat distribution.
Balanced and quiet air conditioning
In cooling mode, the 18,000 BTU capacity is particularly well-suited for combined living spaces typical of condos or medium-sized homes. Each indoor unit operates independently, allowing for:
-
to avoid unnecessarily air-conditioning an unoccupied room,
-
to reduce the sensation of direct cold air,
-
to achieve more consistent comfort during periods of heatwave.
The indoor noise level , which can go down to around 20 dB(A) depending on the configuration chosen, is a real advantage in bedrooms or teleworking spaces.
Essential technical details for an informed choice
When a client consults us, we always emphasize the technical data that has a concrete long-term impact, beyond the simple BTU figure.
Energy efficiency and certifications
The ELIOS E-MULTI system is ENERGY STAR® certified, including cold climate recognition, confirming its suitability for the Quebec market. Its seasonal efficiency ratings (SEER2 and HSPF2) indicate controlled energy consumption in both summer and winter, directly impacting electricity bills.
This level of performance also allows eligibility for the provincial LogisVert subsidy , currently set at $1,620 , an element that we systematically integrate into our profitability analyses for our clients in Laval , Montreal and the surrounding areas.
R-454B refrigerant: a responsible choice
The system uses R-454B refrigerant , known for its lower global warming potential compared to previous generations. For homeowners concerned about the sustainability of their investment and compliance with future standards, this is a significant factor.
From a practical standpoint, this type of refrigerant comes with integrated safety devices, including leak detection and compressor protection mechanisms, which enhances the overall reliability of the system.
Flexible multi-zone configuration
Although this product sheet emphasizes a 2-zone configuration, the compressor offers significant scalability: up to a maximum of 3 zones depending on the final design. This flexibility is particularly valuable in projects where a renovation phase is planned in the medium term.
Compatible indoor units (6,000, 9,000 or 12,000 BTU) allow us to precisely adjust the power to each room, rather than unnecessarily oversizing.
Concrete examples of installations carried out by AirGreen
Single-family home in Laval-des-Rapides
In a two-story house, the client wanted to replace an old, inefficient central air conditioning system upstairs while also improving the heating on the ground floor. We installed an ELIOS E-MULTI 18,000 BTU with two wall units: one in the main living area and the other in the bedroom hallway.
Result :
-
consistent comfort even on nights at −22 °C,
-
significant reduction in electric heating costs
-
Absence of noise pollution, an essential criterion for the master bedroom.
Recently built condo near Montmorency metro station
In this case, the main constraint was the limited outdoor space. The multi-zone system made it possible to serve the living room and bedroom without adding a second outdoor unit, thus complying with condominium regulations while significantly improving summer comfort.
Common mistakes that we systematically avoid
Our field experience has taught us that certain problems often recur when a multi-zone system is poorly designed:
-
choosing an overall power output that is unsuitable for actual needs,
-
poor distribution of BTUs between indoor units
-
installation without analysis of occupancy habits.
At AirGreen, every project begins with a rigorous thermal analysis , taking into account the surface area, insulation, orientation, and actual use of the rooms. This approach avoids long-term disappointments and maximizes the system's lifespan.
Why entrust the installation to AirGreen
Beyond the product itself, the quality of the installation remains crucial. Our teams of certified refrigeration technicians work daily in Laval , Montreal , Longueuil , and on the North and South Shores. We provide:
-
an installation compliant with electrical and mechanical standards
-
a complete commissioning with real-world heating and air conditioning tests
-
clear guidance for the maintenance and optimal use of the system.
We also work with transparent pricing, $5M liability insurance, and structured post-installation follow-up.
Conclusion
The ELIOS E-MULTI 2-head heat pump with an 18,000 BTU compressor is a well-balanced solution for homes in Laval and Greater Montreal seeking reliable, high-performance, and long-lasting multi-zone comfort. Properly sized and installed, it offers an excellent balance of energy efficiency, flexibility, and quiet operation.

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: 16,000 BTU/h at −8 °C, 13,500 at −15 °C.
How many heads can I connect?
Up to 3 on this outdoor unit. This product is configured for 2 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 6 combinations, from 6+6 to 12+12 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$1,920 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 3891349. 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, 60 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.
