A central ADD-ON solution designed to intelligently modernize existing buildings

In the Quebec real estate market, a large proportion of residential, commercial, and multi-unit buildings in Montreal , Laval , Longueuil , the North Shore , and the South Shore already have a functional ductwork system. The real challenge, therefore, is not to start from scratch, but to upgrade the heating and cooling system in a coherent, sustainable, and cost-effective manner .

The ADD-ON Elios central heat pump with coil and cabinet – 48,000 BTU – was developed precisely for this type of project. This system was designed to integrate with existing installations, whether it's an electric furnace, a hybrid system, or an older central condenser that needs replacing.

At AirGreen , we regularly install this model in real-world, often complex, environments: cramped mechanical rooms, occupied buildings, electrical constraints, and high expectations for winter comfort. The ADD-ON approach allows for the addition of a high-performance central heat pump without unnecessary demolition , while immediately improving the building's energy efficiency and thermal stability.

A core performance truly adapted to the Quebec climate

48,000 BTU designed for heating, not just air conditioning

Many central systems boast a high nominal capacity, but their performance drops rapidly when the outside temperature falls below -10°C. This is not the case with the ADD-ON Elios central heat pump .

With a rated output of 48,000 BTU (4 tonnes) , this system is designed to provide reliable heating over an extremely wide temperature range:

• Approximately 37,000 BTU at -8°C

• Approximately 46,000 BTU at -15°C

• Stable and continuous operation down to -30°C

In practice, this means that the system continues to cover a large part of the building's heating needs even during intense cold spells, significantly reducing the need for energy-intensive backup heating.

Inverter technology and intelligent power management

The core of this performance lies in advanced inverter technology , combined with an architecture designed for cold climates. Unlike traditional central systems that abruptly switch between on and off, the compressor continuously adjusts its speed according to the actual building load.

At AirGreen, we have observed the following tangible benefits:

• More stable indoor temperature

• Less variation in humidity

• Reduction of peak electricity consumption

• Less mechanical wear in the long term

This fine modulation is particularly appreciated in open-plan houses and multi-zone buildings, where heating needs vary constantly.

Measurable and consistent energy efficiency throughout the year

Performance indicators tailored to real-world use

The ADD-ON Elios 48,000 BTU central heat pump delivers solid energy performance for a central system in this category:

• SEER2: 15.23 for air conditioning

• HSPF2: 18.815 for seasonal heating

• EER2: 10.02 in instantaneous efficiency

• COP at -8 °C: 1.93

These values ​​are not purely theoretical. In practice, we observe controlled consumption even during periods of intensive heating, which explains the system's eligibility for provincial subsidy programs, including LogisVert , with assistance of up to $4,440 depending on the project.

R-454B refrigerant: compliance and long-term vision

The choice of R-454B refrigerant is part of a responsible transition strategy. This new generation fluid has a reduced global warming potential, while maintaining excellent thermodynamic properties.

A particularly important feature for building owners and managers is the integrated leak detection system . The system continuously monitors the condition of the refrigeration circuit. In case of an anomaly:

• The compressor is automatically switched off

• Air circulation is maintained

• A service alert is generated

This approach enhances security and protects long-term investment.

Serpentine WITH cabinet: a strategic technical choice

Why choose a coil with an ADD-ON cabinet?

In replacement or modernization projects, the coil with cabinet (interior model GCHMA48RCAS1) offers several concrete advantages:

• Rigid casing for easy installation

• Improved overall system sealing

• Cleaner integration with existing ductwork

• Enhanced protection of internal components

Its dimensions ( 21.61 × 21.5 × 27.8 in ) make it compatible with many mechanical rooms, including in older houses in Montreal or multi-unit residential buildings in Longueuil.

Airflow, balance and real comfort

With an airflow of up to 1,160 CFM , this coil ensures even distribution of heated or cooled air. However, performance depends on more than just the equipment.

At AirGreen, each installation includes:

• Analysis of the existing conduit network

• Adjusting the registers and air outlets

• The final balancing of the system

These steps are essential to avoid cold spots, overpressures, and discomforts often associated with poorly configured central systems.

Quiet operation and exterior integration

Acoustic comfort is an increasingly important criterion, especially in the dense residential areas of Laval or the South Shore . The outdoor unit of this model has a noise level of approximately 65 dB(A) , making it significantly quieter than many older central systems.

Its compact, horizontal discharge design also facilitates its aesthetic integration, whether in a backyard, on the side of a building, or near a service entrance.

Concrete examples of installations carried out by AirGreen

Single-family home – North Shore

In a residence equipped with an aging electric furnace but with ductwork in excellent condition, we installed an ADD-ON Elios 48,000 BTU central heat pump with a coil and cabinet. The client wanted to reduce their heating costs while maintaining a reliable solution during periods of extreme cold.

Observed results:

• Immediate improvement in comfort

• Significant reduction in electricity consumption

• Access to the LogisVert subsidy

• Work completed without major disruption

Multi-unit residential building – Longueuil

In a rental building, the priority was stability and reliability in winter. The system's ability to operate down to -30°C made it possible to limit the use of backup systems, while ensuring consistent comfort for the occupants.

Common mistakes to avoid with ADD-ON core systems

Our field experience has allowed us to identify several common mistakes:

• Choosing the capacity without precise thermal calculation

• Neglecting the compatibility between the coil and the ducts

• Underestimating the importance of air balancing

• Installing without planning for the future evolution of the building

Each AirGreen project begins with a comprehensive analysis to avoid these pitfalls and ensure sustainable performance.

Guarantee, reliability and professional support

The ADD-ON Elios central heat pump is covered by a 10-year warranty on the compressor and parts , with additional protection options depending on customer needs.

Beyond the warranty, reliability depends on the quality of the installation. Our certified refrigeration technicians operate throughout Montreal , Laval , Longueuil , on the North Shore and the South Shore , with a rigorous, documented and transparent approach.
