A central solution designed for existing Quebec buildings

At AirGreen, we work daily on real, inhabited buildings, often built 20, 30, or 50 years ago, with very real constraints: existing ductwork, limited electrical panels, aging dual-energy systems, or old electric furnaces that have become expensive to operate. The ELIOS R410A "ADD-ON" central heat pump – 4 tons – is designed precisely for this type of project.

This model wasn't designed for ideal homes on paper, but for the real estate market in Montreal, Laval, Longueuil, the North Shore, and the South Shore . Its ADD-ON concept allows for the addition of a high-performance central heat pump to an existing system, without starting from scratch. This means less demolition, fewer structural modifications, and above all, much smarter integration with existing systems.

In many projects completed by our teams, this approach allows homeowners to modernize their heating and air conditioning without turning their house into a prolonged construction site. It's a pragmatic, consistent solution perfectly suited to local realities.

A 4-tonne capacity suitable for large volumes

With a rated capacity of 48,000 BTU , the ELIOS 4T central heat pump meets the needs of large residences, multi-story homes, multi-unit dwellings, and several light commercial buildings. This capacity allows for uniform air distribution throughout the ductwork, provided that the sizing and balancing are performed correctly.

At AirGreen, we place particular emphasis on this point: a high-performing central heat pump is more than just its technical specifications. Its actual efficiency depends on the quality of the installation, the airflow, the ductwork configuration, and the electronic controls. That's why every project begins with a detailed building analysis, not simply a replacement with equivalent capacity.

Reliable heating down to -30°C: an essential factor in Quebec

One of the most important factors for our customers remains heating performance in cold weather. The ELIOS R410A central heat pump is designed to operate down to -30°C , making it perfectly suited to the harsh winters we experience year after year.

In practical terms, this means:

• A significant reduction in the use of auxiliary electric heating elements

• A more stable indoor temperature during cold spells

• Improved predictability of energy costs

In several projects carried out in Laval and on the North Shore, this ability to maintain high heat production in very cold weather has allowed our clients to reduce their overall electricity consumption from the first full heating season.

Inverter technology and HEAT+: intelligent modulation and constant efficiency

The ELIOS central heat pump incorporates advanced Inverter technology , combined with the HEAT+ function, specially designed for northern climates. Unlike traditional systems that constantly switch on and off, the Inverter compressor continuously adjusts its power according to the building's actual needs.

This fine modulation offers several concrete advantages:

• Fewer temperature fluctuations

• Reduction in peak consumption

• Reduction of mechanical wear on the compressor

• Quieter operation

In practice, this translates into more consistent daily comfort. Occupants experience fewer sudden variations, particularly in rooms far from the plenum or located on upper floors, a common issue in single-family homes.

Measurable and consistent energy efficiency

The efficiency values ​​of the ELIOS 4T central heat pump demonstrate an interesting balance between performance and stability:

• SEER2: 14.3

• HSPF2: 19.0

• EER2: 18.6

• COP at -8 °C: 11.83

This data becomes truly meaningful when considered in relation to a properly calibrated installation. In several projects completed in Longueuil and Boucherville, we observed a measurable decrease in annual electricity consumption, without compromising comfort.

Quieter operation, both indoors and outdoors

Noise is often a point of contention in dense residential areas. The ELIOS central heat pump stands out with its noise-reduction-focused design, boasting an outdoor sound level of approximately 64 dB(A) for the 4-tonne version.

For our customers, this means:

• Less noise pollution for the occupants

• Better coexistence with the neighbors

• A more acceptable installation in urban areas

Inside, the stability of the Inverter compressor also reduces the sudden start-up and stop noises often associated with older central systems.

A compact and easy-to-integrate outdoor unit

The outdoor unit of the ELIOS central heat pump features a side vent , making it significantly more compact than many traditional models. This is particularly advantageous for projects in urban areas or on limited land.

For our teams, this design offers:

• More flexibility for location

• A more discreet visual integration

• Improved compliance with municipal regulations

Inside, the boxed coil was designed to integrate efficiently into existing mechanical rooms, a critical point in homes where space is limited.

Key technical specifications – 4-tonne version

• Cooling capacity: 48,000 BTU

• High heating capacity at low temperature

• Refrigerant gas: R-410A

• Power supply: 220 V

• Piping: 3/8 – 3/4

• MCA: 40 A

• MOP: 50 A

• Wi-Fi: optional via compatible thermostat

These parameters are systematically validated by our refrigeration engineers to ensure perfect compatibility with the building's existing infrastructure.

Warranty and long-term protection options

The ELIOS central heat pump is covered by a 10-year warranty on the compressor and parts . Labor is not included as standard, which is common in this product category.

In several projects, particularly for rental buildings on the South Shore, we recommend additional warranty options to secure the long-term investment and simplify maintenance management.

Real-world example of an ADD-ON installation on the South Shore

In a recent project in Saint-Hubert, our teams replaced an old, energy-inefficient central electrical system with a 4-ton ELIOS central heat pump in an ADD-ON configuration. The existing ductwork was retained after adjustments and balancing.

Result :

• Work completed quickly

• Immediate improvement in comfort

• Significant reduction in electricity consumption

• No compromise on air distribution

This type of project perfectly illustrates the relevance of this model for owners wishing for a gradual and well-controlled energy transition.

Key points to check before installation

Even with a high-performing product, certain elements remain essential:

• Analysis of the actual thermal load

• Condition and sizing of the ducts

• Available electrical capacity

• Choosing the right thermostat for everyday use

At AirGreen, these checks are an integral part of our process, in order to avoid problems of underperformance or oversizing.
