A multi-zone solution designed for the real climate of Greater Montreal

At AirGreen, we have been installing multi-zone HVAC systems for years in single-family homes, duplexes, and multi-unit buildings in Longueuil , Montreal , Laval , and on the North and South Shores . The ELIOS E-MULTI 6-head heat pump with a 48,000 BTU compressor is one of the systems we recommend when the needs are clear: to efficiently heat and cool multiple rooms, with precise zone control, without requiring multiple outdoor units.

This model was designed to meet the very specific constraints of Quebec: long winters, significant temperature differences, buildings with varied configurations, high requirements in terms of energy efficiency and eligibility for provincial subsidies.

Why a 6-head multi-zone system truly changes the comfort experience

In practice, a multi-zone system is only worthwhile if it is correctly sized and installed. The ELIOS E-MULTI 48,000 BTU can supply up to 6 independent zones , each with its own indoor unit. This means:

• Temperature adjusted room by room , without compromise.

• Reduction of comfort conflicts between floors, rooms and common areas.

• Optimization of electricity consumption , because only the areas actually used are working.

• A single outdoor unit , a major advantage for municipal regulations, condominiums and the aesthetics of facades.

In several projects carried out by AirGreen in Longueuil and Boucherville , this type of configuration made it possible to replace old partial electric or forced-air systems, while preserving the architectural integrity of the buildings.

Concrete examples of compatible indoor units

The system's flexibility is a key point: it accepts different styles of indoor units depending on the actual needs of the occupants:

• Wall-mounted units (6,000 to 24,000 BTU) for bedrooms and living rooms.

• Discreet ducted units for corridors or open areas.

• 4-way cassettes for suspended ceilings.

• Single-channel cassette decks and consoles , often chosen in targeted renovations.

This modularity allows AirGreen to adapt each project, rather than forcing a single solution.

Technical performance adapted to Quebec winters

Reliable heating down to -25°C

The heating capacity down to -25°C is not just a marketing gimmick. In practice, this means the system continues to provide consistent heat during periods of intense cold, which are common in Montreal , Laval , and the North Shore . At -8°C, the heating output remains high, reducing reliance on supplemental electric heating.

In homes where we replaced electric baseboard heaters with this model, customers have noticed increased thermal stability and better heat distribution, even in distant rooms.

Measurable energy efficiency

The inverter compressor and R-454B refrigerant contribute to high efficiency:

• SEER2 up to 21.3 depending on the configuration.

• HSPF2 is efficient for seasonal heating .

• ENERGY STAR® , including cold climate certification.

These features make the ELIOS E-MULTI 48,000 BTU eligible for the provincial LogisVert grant , currently valued at $4,080 , a deciding factor for many homeowners.

Silence, safety and everyday comfort

Controlled noise levels

Indoors, depending on the unit chosen, the noise level can drop to approximately 20 dB(A) in low mode. Outdoors, the compressor registers approximately 65 dB(A) , a value we consider acceptable for densely populated residential areas of Longueuil and Montreal , provided the installation is properly planned (anti-vibration mounts, strategic location).

Safety related to R-454B refrigerant

The system incorporates refrigerant leak detection mechanisms. In case of a malfunction:

• The compressor stops automatically.

• The internal fan continues to operate to limit the concentration of refrigerant.

• A shut-off valve reduces the flow rate.

These elements are particularly important in multi-zone installations where several indoor units are distributed throughout the dwelling.

What we systematically check during the AirGreen installation

A high-performing multi-zone system depends directly on the quality of the installation. At AirGreen, we pay particular attention to:

• Precise calculation of thermal loads per zone.

• Compliance with the liquid and gas piping diameters for each evaporator.

• Managing maximum lengths and elevation changes.

• Electrical compliance: 220 V , MOP 45 A , suitable circuit breaker.

• The positioning of the units to avoid air recirculation and noise pollution.

We have seen similar systems, poorly installed elsewhere, lose up to 20% of their actual effectiveness. This is precisely what we are avoiding.

Guarantee and peace of mind

The configuration offered by AirGreen for this model typically includes:

• 10 years on the compressor

• 10-year warranty on parts

• Labor costs according to the option chosen

In a multi-zone context, this coverage is essential, as it protects a significant investment over the long term.

Who is the ELIOS E-MULTI 6-head 48,000 BTU really for?

This system is particularly suitable for:

• Large single-family homes.

• Duplexes, triplexes and small apartment buildings.

• Properties with varying comfort requirements depending on the room.

• Projects where only one exterior unit is required by regulation or aesthetic choice.

In Longueuil , several of our clients have chosen this model to modernize existing buildings without completely redoing the ducts or central systems.
