A central ADD-ON solution designed to modernize existing systems without compromise

At AirGreen , we are regularly called upon to work in buildings where the ductwork is still in good condition, but the heating or cooling system is outdated, expensive to operate, or inefficient during periods of extreme cold. It is precisely in this context that the ADD-ON Elios 60,000 BTU central heat pump with coil and cabinet becomes so valuable.

This model is designed for residential owners, property managers, and operators of light commercial buildings in Montreal , Laval , Longueuil , and on the North and South Shores who want to improve the energy efficiency of their central heating system without starting from scratch. The ADD-ON approach allows for the integration of a modern heat pump into an existing installation, while respecting the building's mechanical, electrical, and budgetary constraints.

With a certified heating capacity down to -30°C , a power of 60,000 BTU (5 tonnes) and a design tailored for the Quebec climate, this central heat pump stands out as a robust, reliable and durable solution for large areas.

The Elios ADD-ON logic: a realistic approach to HVAC replacement

Why the ADD-ON is often the best technical decision

In practice, completely replacing a central system can quickly become complex: partial demolition, major modifications to the ductwork, high costs, and extended delays. In many cases, these interventions are unnecessary.

The ADD-ON Elios central heat pump allows:

• to retain the existing duct network when it is properly sized,

• to add an A-frame coil with cabinet , designed for a clean and structured integration,

• to connect a high-modulation inverter outdoor unit ,

• to immediately improve the overall energy efficiency of the building.

At AirGreen, we use this approach in a wide variety of projects. In Laval , for example, we modernized a large single-family home built in the early 2000s. The ductwork was efficient, but the electric central heating system was generating excessive costs. Integrating an Elios ADD-ON 60,000 BTU allowed for a seamless transition to a much more efficient central heating system, without major modifications to the existing infrastructure.

Heating performance designed for extreme winters

Thermal stability down to -30 °C

In a climate like that of Montreal and the North Shore , a system's ability to maintain comfort in extreme cold is a crucial factor. The ADD-ON Elios central heat pump stands out for its ability to maintain stable heat output even when temperatures plummet.

Specific operational data:

• Rated power : 60,000 BTU

• Available power at -8°C : approximately 36,000 BTU

• Available power at -15°C : approximately 43,000 BTU

• Continuous operation down to -30°C

Thanks to Inverter technology combined with the HEAT+ system , power is never delivered abruptly. The compressor constantly adjusts its speed to precisely meet the building's needs. This fine modulation allows for:

• a more stable indoor temperature

• a reduction in on/off cycles

• reduced mechanical wear,

• better management of indoor humidity.

In several projects carried out by AirGreen in Longueuil and on the South Shore , this stability has resulted in significantly greater comfort in rooms far from the centre of the building, which are often problematic with older central systems.

Energy efficiency and figures that really matter

Useful performance indicators in the field

Beyond theoretical values, it's the measurable performance under real-world conditions that interests our customers. The ADD-ON Elios central heat pump delivers solid results:

• SEER2 : 15.2 (seasonal air conditioning efficiency)

• EER2 : 10

• HSPF2 : up to 6.8 depending on the climate region

• COP at -8.3 °C : approximately 2.14 to 2.76 depending on the configuration

These indicators translate into tangible energy savings, particularly in buildings heated primarily by electricity. In some cases observed by our teams, the annual heating bill decreased significantly from the very first full season of use.

R-454B refrigerant: compliance, safety and the future

The Elios ADD-ON central heat pump uses R-454B refrigerant , a strategic choice from both a regulatory and environmental perspective.

This refrigerant allows:

• compliance with current A2L standards

• a reduction in environmental impact compared to previous generations,

• improved compatibility with new security requirements.

The system also incorporates active leak detection , capable of stopping the compressor and maintaining airflow in the event of a malfunction. This feature is particularly valuable in multi-unit residential and commercial buildings, where risk management is paramount.

Dimensions, mechanical integration and actual constraints

Suitable for existing mechanical rooms

Before each installation, AirGreen performs a complete check of the available space. The dimensions of the 60,000 BTU version with cabinet facilitate its integration into many configurations:

• Coil with cabinet : 24.49 × 21 × 27.99 inches

• Outdoor unit : 37.48 × 16.34 × 52.48 inches

• Outdoor noise level : approximately 64 dB(A)

The compact size of the horizontal discharge outdoor unit allows for more discreet installation, even in dense urban environments such as certain areas of Montreal .

Concrete examples of installations carried out by AirGreen

Single-family home in Pierrefonds

In this project, the client was hesitating between a complete replacement of the central system and an add-on solution. After inspection:

• properly sized ducts

• adequate mechanical space

• A real need for power in winter.

The Elios ADD-ON 60,000 BTU solution was the obvious choice. The project was completed more quickly, the budget was better controlled, and comfort was improved from the very first weeks of use.

Rental building on the South Shore

For a small apartment building, the priority was reliable and consistent heating. The Elios central heat pump was integrated into a hybrid configuration, allowing for efficient management of the heating load while reducing the building's overall electricity consumption.

Common mistakes that our team anticipates and avoids

The effectiveness of a central system depends as much on its design as on its installation. At AirGreen, we pay particular attention to:

• the suitability of the airflow (CFM) to the existing ductwork,

• electrical sizing (MCA, MOP, protections),

• the quality and length of the 3/8 – 3/4 refrigeration piping ,

• the precise balancing of the duct network.

A high-performance central heat pump, if poorly integrated, can quickly lose some of its advantages. Our role is precisely to avoid these situations.

Guarantee, support and peace of mind

The ADD-ON Elios 60,000 BTU central heat pump is offered with:

• 10 years on the compressor

• 10-year warranty on parts

• 0 years on labor costs (options available)

At AirGreen , each project includes:

• a clear final offer before work begins

• An installation carried out by certified and experienced refrigeration technicians .

• $5,000,000 liability insurance

• structured and accessible post-installation support.
