A multi-zone solution designed for the residential and multi-unit realities of Greater Montreal

At AirGreen, we've been installing HVAC systems long enough to know that a multi-zone product is never chosen by chance. It's almost always the result of a very specific context: multi-story houses with very different thermal zones, renovated duplexes in Laval, condos without existing ductwork, or residences where precise room-by-room control is desired without multiplying the number of outdoor units.

The ELIOS E-MULTI 4-head heat pump with a 36,000 BTU compressor perfectly meets this type of need. It can supply up to four independent zones from a single high-performance outdoor unit, designed to operate efficiently down to -25°C , a non-negotiable requirement for the climate of Laval, Montreal, the North Shore and the South Shore .

In several recent projects completed by our team, including single-family homes in Laval-des-Rapides and rental buildings in Duvernay, this model has proven itself for its stability in winter heating, its configuration flexibility and its excellent energy performance eligible for the LogisVert subsidy .

A truly flexible multi-zone architecture

One compressor, multiple comfort realities

The heart of the system lies in the EXHSA3652AV1 outdoor unit, a 36,000 BTU compressor capable of powering several types of indoor units: wall-mounted, 4-way cassette, console, or ducted units. This flexibility is essential in real-world situations. Very often, a single home presents a variety of challenges: an open-plan living room, closed bedrooms, a more humid basement, or an upper floor facing due south.

With this system, each zone is managed independently:

• target temperature per room

• simultaneous operation in heating or air conditioning

• adjusting the airflow according to actual usage

This not only allows for greater comfort , but also a concrete reduction in energy consumption , since only occupied areas are used.

Actual heating capacity in cold weather

One point we always check when analyzing a project is the power available in real winter conditions , and not just the nominal value.

Based on this model:

• 36,000 BTU nominal

• 27,000 BTU at -8°C

• 26,000 BTU at -15°C

• guaranteed operation down to -25°C

In installations carried out in Laval and on the North Shore , we have observed excellent thermal stability even during prolonged periods of cold, where less well-sized systems begin to lose efficiency or require supplementary heating.

Energy efficiency and compliance with Quebec programs

Measurable performance and certifications

The ELIOS E-MULTI 36,000 BTU heat pump boasts efficiency values ​​that clearly place it in the category of high-performance multi-zone systems:

• ENERGY STAR®

• ENERGY STAR® – cold climate

• SEER2 up to 23.1

• High HSPF2 for heating

• COP of 12.03 at -8 °C

These performance levels allow access to the LogisVert subsidy , currently estimated at $3,240 for this model, a determining factor in the final decision of several clients in Laval and on the South Shore .

R-454B refrigerant: a choice aligned with the new standards

The system uses R-454B gas , a new-generation refrigerant with a reduced global warming potential , in line with current environmental guidelines. In practice, this also translates to:

• improved pressure stability

• increased thermal efficiency

• integrated leak detection and safety devices

These elements are particularly important in multi-zone configurations, where several evaporators are connected to the same outdoor unit.

Choice of indoor units: true personalization

Extended compatibility according to building needs

Depending on the project configuration, we can integrate different models of compatible indoor units, including:

• EWHMA06 / 09 / 12 / 18 / 24 / 33

• Wall-mounted for enclosed rooms

• 4-way cassettes for open areas

• Ducted units for discreet integration

In a recent project in a triplex in Laval, we combined two wall-mounted units in the bedrooms, a 4-way cassette in the living room, and a ducted unit for an office space, all powered by the same compressor. This type of configuration would be much more complex, if not impossible, with traditional systems.

Controlled acoustic comfort

One aspect often underestimated by customers, but immediately noticeable after installation, is the noise level :

• Indoor units from 20 dB(A) depending on the model

• outdoor unit at 63 dB(A)

In townhouses in Laval or terraced condos, this quietness makes a real difference in everyday life, especially at night.

HVAC installation: where AirGreen's expertise makes the difference

Multi-zone sizing and balancing

Installing a multi-zone heat pump is more than just connecting units. At AirGreen, every project begins with:

• a detailed thermal analysis

• calculating charges per room

• validation of pipe lengths

• strict adherence to MCA and MOP values ​​(35A)

Improper balancing can lead to uneven performance, excessive energy consumption, or premature compressor wear. This is a mistake we regularly correct in installations carried out without prior analysis.

Concrete feedback from our customers

Across several installations carried out in Laval, Montreal and Boucherville , the feedback is consistent:

• consistent comfort between floors

• better humidity management in summer

• significant reduction in energy bills

• absence of noisy or unstable cycles in winter

These results are not theoretical: they come from real projects monitored by our after-sales service team.

Guarantee and sustainability of the system

The system is covered by:

• 10 years on the compressor

• 10-year warranty on parts

• 0 years on labor costs (option available)

We always clearly explain these elements before installation, as transparency is an integral part of our approach. An additional warranty on labor can be added depending on the project and the client's expectations.
