ELIOS E-MULTI 2-Head Heat Pump + 48,000 BTU Compressor | Longueuil

A multi-zone solution designed for the residential and multi-unit realities of the South Shore

At AirGreen , we have been installing multi-zone HVAC systems in Longueuil and throughout the South Shore for many years. The ELIOS E-MULTI 2-head heat pump with a 48,000 BTU compressor is one of the configurations we recommend when the needs are clear: to efficiently heat and cool several distinct spaces, with precise zone control, while maintaining excellent energy efficiency even in extreme cold.

This type of system is suitable for single-family homes , plexes , condos , as well as small multi-unit buildings where the usual compromises of classic centralized systems are to be avoided.

A flexible, multi-zone architecture that is truly usable in the field

The heart of this configuration lies in a 48,000 BTU ELIOS E-MULTI outdoor unit , capable of powering up to 6 indoor units , even though the version shown here is configured with 2 active zones . This reserve capacity offers a tangible advantage:
• improved heating stability
• fewer short cycles
• future scalability without compressor replacement

In practice, in Longueuil, we often see this system installed in buildings where an extension, a finished basement or a conversion into additional housing is planned in the medium term.

Extended compatibility of indoor units

The system accepts several formats:

• EMC wall units (6,000 to 24,000 BTU)

• ducted units

• 1-channel or 4-channel cassettes

• consoles

This diversity makes it possible to adapt the HVAC design to the actual architecture of the building, without imposing a single type of air emitter.

Heating efficiency: a concrete response to Longueuil's climate

One of the most important criteria for our customers remains the heating capacity in cold weather .
This ELIOS model is designed to operate down to -25°C , with measured and consistent performance.

Key data for the 48,000 BTU model:

• Rated capacity : 48,000 BTU

• Power at -8°C : ~34,000 BTU

• Power at -15°C : ~36,000 BTU

• COP at -8 °C : 3.9

• ENERGY STAR® Certification – Cold Climate

In practice, this means a real reduction in the use of auxiliary heating , even during the prolonged cold spells that regularly affect the South Shore of Montreal .

Energy efficiency and R-454B refrigerant: a choice for the future

The ELIOS E-MULTI heat pump uses R-454B refrigerant , known for:

• a reduced global warming potential (GWP)

• increased compliance with future environmental standards

• improved volumetric efficiency

The performance indicators are solid:

• SEER2 up to 21.3

• High HSPF2 in multi-zone configuration

• EER2 optimized for actual loads

For our customers in Longueuil, this translates into better-controlled electricity bills , particularly during periods of prolonged summer air conditioning.

Zone-based comfort management: an often underestimated daily advantage

Each zone operates independently. In practice, this allows:

• to lower the temperature in unoccupied rooms

• to adapt comfort according to sun exposure

• to limit conflicts over adjustments in families or multiple dwellings

We regularly observe that this fine-tuning of comfort not only improves satisfaction, but also the overall lifespan of the system, because the machine works more intelligently.

Noise level: a critical point that has been controlled

In Longueuil's dense residential projects, noise is a real issue.

• Outdoor unit : ~65 dB(A)

• Indoor units : up to 20 dB(A) depending on the model and speed

During installation, AirGreen pays particular attention to:

• the exact location of the compressor

• vibration isolation

• the configuration of the supports

These details make a tangible difference on a daily basis.

HVAC Installation in Longueuil: What We Do Differently at AirGreen

Beyond the product itself, the quality of HVAC installation determines 50% of the actual performance.
On this type of ELIOS E-MULTI system, our teams systematically take into account:

• load calculation by zone

• the exact length of piping

• refrigeration balancing

• future access for HVAC maintenance

We have installed similar configurations in Longueuil-East, Saint-Hubert, Greenfield Park and in several condominiums on the South Shore, with very positive feedback on the stability of winter heating.

LogisVert subsidy: a major financial lever

This heat pump is eligible for the LogisVert provincial subsidy , with an amount of up to $4,080 (updated November 2025).
We support our clients in Longueuil with:

• validation of eligibility

• AHRI number compliance

• the preparation of the file

This often tips the decision in favor of a high-efficiency multi-zone system rather than a minimal solution.

Guarantee and peace of mind

Standard configuration:

• Compressor : 10 years

• Parts : 10 years

• Labor : 0 years (extension possible)

Depending on the project, we offer tailored extended warranties , particularly relevant for income properties or long-term owner-occupiers.

For whom is this heat pump really suitable?

This model is particularly relevant if:

• you have several spaces at different temperatures

• You want a scalable system

• You prioritize efficient electric heating

• Your building is located in Longueuil or on the South Shore , with exposed winters

Conversely, for very small areas or a single open space, a different configuration might be more appropriate. This is precisely the type of analysis we conduct before each submission.

Why choose AirGreen for your ELIOS project in Longueuil?

We don't just sell equipment. We deliver a complete HVAC solution , designed to:

• the local climate reality

• the actual use of the building

• long-term sustainability

Our approach is based on transparent pricing , experienced refrigeration technicians , and a strong local presence in Longueuil, Montreal, Laval, North Shore and South Shore.
