An ADD-ON central heat pump designed for the real conditions of Quebec

At AirGreen , we never select a central system based solely on a technical specification sheet. Every product we offer must first prove its suitability in real-world conditions, within existing buildings, under real installation constraints and in the sometimes extreme climatic conditions of Montreal , Laval , Longueuil , the North Shore , and the South Shore . The ADD-ON Elios 30,000 BTU central heat pump perfectly embodies this approach.

This model was designed for conversion , modernization , or energy optimization projects where a house or building already has a ductwork system and often an electric furnace or hybrid system. The ADD-ON approach allows for significant improvements in the building's overall performance without unnecessary demolition or complete reconstruction of the central system.

The ability to maintain heating down to -30°C is a crucial factor. In Quebec, a central heating system that performs well at -10°C but fails during extreme cold is simply unacceptable. With the Elios ADD-ON, consistent comfort remains stable even during prolonged periods of cold.

A core technology that goes beyond simply adding equipment

A-shaped coil: a key element often underestimated

The A-coil integrated into this ADD-ON central heat pump plays a central role in the overall system performance. Unlike older or generic coils, this one is designed to maximize heat exchange in variable-speed central configurations. This allows the system to operate precisely, without excessive cycling, while ensuring even distribution of heated or cooled air throughout the entire duct network.

In the projects we have carried out in Boucherville and on the North Shore , this design has made it possible to eliminate significant temperature differences between floors, a problem frequently encountered with poorly adapted or oversized central systems.

Intelligent communication between components

The Elios ADD-ON stands out thanks to its bidirectional communication between the indoor and outdoor units. This real-time interaction allows for precise capacity modulation, unlike older 24V central control systems that only operate in on/off mode.

In practical terms, this means:

• an instant adaptation to the building's actual thermal needs,

• a marked reduction in peak electricity consumption,

• quieter operation

• and improved stability of indoor humidity.

These advantages become particularly noticeable in well-insulated or energy-renovated homes, where a traditional central system would tend to overheat or operate in cycles that are too short.

Heating and cooling performance under real-world conditions

Reliable heating even in very cold weather

The ADD-ON Elios 30,000 BTU central heat pump offers a nominal heating capacity suitable for single-family homes, duplexes, and some multi-unit buildings. At -8°C , it provides approximately 25,000 BTUs , and its capacity remains high down to -15°C , significantly reducing the need for supplemental heating.

In several projects carried out in Montreal , we have found that clients can delay, or even greatly limit, the activation of their electric furnace, which directly translates into savings on the winter energy bill.

Stable and comfortable central air conditioning

In cooling mode, the 30,000 BTU capacity ensures consistent comfort even during heat waves. Inverter modulation prevents sudden temperature fluctuations and reduces the dry air effect often associated with older central systems.

For open-plan buildings, this stability is particularly appreciated, as it eliminates overcooled areas and improves the overall feeling of comfort.

Essential technical data for an informed choice

For property owners and managers who want a clear vision before committing, here are the most relevant technical elements:

• Nominal capacity : 30,000 BTU (2.5 tonnes)

• Certified heating capacity : down to -30°C

• Refrigerant : R-454B , A2L compatible

• SEER2 : 16.1

• HSPF2 : 8.2 (cold climate)

• COP at -8 °C : approximately 2.5

• Outdoor noise level : ~62 dB(A)

• Piping : 3/8 – 3/4

• Power supply : 208–230 V single phase

• ENERGY STAR® cold climate certification : yes

These technical characteristics explain why this model is eligible for the $3,000 LogisVert grant , a major financial incentive for owners wishing to improve the energy performance of their building.

Installation scenarios encountered by AirGreen

Existing house with electric furnace – Laval

In this type of project, the goal is rarely to replace everything. The Elios ADD-ON allows you to keep the electric furnace as a backup system while providing the majority of your heating with the heat pump. This hybrid configuration offers excellent energy security and reduces annual operating costs.

Multi-unit housing on the South Shore – noise and space constraints

In multi-unit residential buildings, noise levels and exterior footprint are often critical factors. The horizontal discharge condenser, more compact than many vertical models, facilitates integration without disturbing residents or neighbors. In this context, the difference between a traditional central system and the ADD-ON Elios becomes immediately apparent.

Safety, reliability and long-term HVAC maintenance

R-454B refrigerant and integrated safety features

The choice of R-454B is part of a transition towards more environmentally friendly refrigerants. The Elios ADD-ON incorporates safety devices that continuously monitor the system. In the event of a malfunction, operation is automatically adjusted to protect the equipment and the building.

HVAC Maintenance: An Often Neglected Factor

Even the best central system requires rigorous maintenance. At AirGreen , we emphasize:

• the annual inspection of the coil,

• checking airflow rates,

• cleaning critical components,

• and the control of electrical parameters.

These simple interventions help to preserve the advertised performance and avoid the drops in efficiency that we too often observe on poorly maintained systems.

Guarantees and long-term peace of mind

The ADD-ON Elios central heat pump comes with a robust warranty covering the compressor and parts for an extended period, with the option to add further protection as needed for your project. This coverage, combined with professional installation, ensures lasting peace of mind.

Why entrust your ADD-ON project to AirGreen

Installing an ADD-ON central heat pump is not a simple equipment replacement. It requires a thorough understanding of the building, existing ductwork, actual heat loads, and occupants' usage patterns.

At AirGreen , we approach every project in Montreal , Laval , Longueuil , and on the North and South Shores with a thorough analysis, a clear final offer, and meticulous commissioning. This approach ensures that the ADD-ON Elios 30,000 BTU central heat pump operates at its full potential, year after year.
