A central ADD-ON solution designed for Quebec's real climate

At AirGreen , we have been installing ADD-ON central systems for many years in very concrete contexts: replacing existing electric heating, adding a heat pump to an existing forced air system, modernizing hybrid installations in single-family homes, duplexes or small buildings in Montreal , Laval , Longueuil , on the North Shore and the South Shore .
The ADD-ON Elios 18,000 BTU Central Heat Pump with coil WITH cabinet is one of the solutions we favor when the customer seeks a clear balance between winter performance, clean integration with the existing system and control of installation costs.

Unlike many central heat pumps designed primarily for milder climates, this model is truly suited to Quebec winters, with a certified heating capacity down to -30°C , without immediately relying on an energy-intensive backup heating system.

An add-on design that simplifies replacements and upgrades

Direct integration into existing systems

In many projects carried out by AirGreen, clients already have:

• of a central electrical system ,

• of an electric or hybrid furnace ,

• or a network of conduits in good condition but with equipment that has become inefficient.

The Elios ADD-ON configuration allows you to add the heat pump without rebuilding the entire system. The coil WITH cabinet (indoor model GCHMA24RBAS1 ) integrates neatly into the existing plenum, which reduces:

• modifications to conduits,

• construction time,

• and unforeseen costs.

This is a point we systematically check during our technical home assessments, particularly in older homes in Montreal East , Laval-des-Rapides or Longueuil .

Actual heating performance: a non-negotiable criterion in Quebec

Stable capacity in cold weather

This ADD-ON central heat pump features:

• 18,000 BTU rated power,

• 15,200 BTU at -8°C ,

• 18,000 BTU at -15°C ,

• and operation maintained down to -30 °C .

In practice, this means that the system continues to provide useful heat even during the cold spells that we regularly experience on the North Shore and in some exposed areas of the South Shore .

COP and energy efficiency

With a COP of approximately 2.7 at -8.3 °C , the heat pump transforms each kilowatt consumed into several kilowatts of useful heat.
At AirGreen, we always explain to our clients that this yield has a direct impact on:

• the winter electricity bill,

• reducing the use of auxiliary heating,

• and the stability of interior comfort.

Efficient and even central air conditioning

In summer, the 18,000 BTU cooling capacity allows for efficient air conditioning of medium-sized residences with uniform distribution in all rooms connected to the ducts.

The efficiency values ​​are particularly high for a central system:

• SEER2: 16.1

• EER2: 11.7

In the homes we have equipped in Boucherville or Laval , this translates into stable air conditioning, without overconsumption, even during prolonged periods of heat.

Inverter technology and intelligent modulation

The Inverter technology integrated into the ADD-ON Elios heat pump allows for variable speed operation. Unlike conventional on/off systems, the compressor continuously adjusts its power according to the actual needs of the building.

The tangible benefits observed by our clients:

• more stable temperature

• fewer short cycles,

• noise reduction,

• slower mechanical wear.

This modulation is particularly appreciated in open-plan houses or partially renovated buildings where thermal loads vary from one area to another.

R-454B refrigerant: efficiency and current compliance

The system uses R-454B refrigerant , which complies with new environmental standards and is compatible with A2L requirements.
At AirGreen, we have already adapted our installation and safety procedures for this type of refrigerant, particularly during recent projects in Montreal and Longueuil .

This choice allows:

• a reduction in environmental impact,

• long-term regulatory compliance,

• and a better sustainability of the system.

Noise level and outdoor integration

The outdoor unit (model ESHMA18R2AN1 ) has a noise level of approximately 58 dB(A) .
In densely populated areas or on narrower plots of land, this factor is crucial for:

• respect the neighborhood

• to avoid complaints,

• and maintain a pleasant outdoor environment.

We pay particular attention to the location of the condenser during each installation, taking into account local municipal constraints.

Key technical data for well-planned projects

• Capacity : 1.5 tonnes (18,000 BTU)

• Voltage : 220 V

• Piping : 3/8 – 3/4

• Airflow (CFM) : up to 1,500

• Indoor unit dimensions : 17.52 × 21 × 17.99 in

• Outdoor unit dimensions : 35.04 × 13.46 × 26.5 in

These parameters are systematically checked by our technicians to ensure perfect compatibility with the existing installation.

LogisVert subsidy: a concrete financial advantage

This model is eligible for the LogisVert provincial grant , with an amount of up to $1,824 (updated: November 2025).
At AirGreen, we support our clients in Montreal , Laval , Longueuil , the North Shore and the South Shore in:

• validation of eligibility,

• preparing the file,

• and compliance with the required technical criteria.

Why AirGreen for an Elios ADD-ON installation?

Each ADD-ON central installation requires real expertise: load calculations, duct analysis, electrical verification, airflow adjustment.
At AirGreen , we combine:

• certified refrigeration technicians ,

• $5 million liability insurance ,

• Clear pricing before work begins .

• and proven field experience on hundreds of central installations in Quebec.

Our goal is not simply to install equipment, but to ensure measurable performance over several years.
