A central solution designed for smart replacements and real buildings in Quebec

At AirGreen, we have been installing and replacing central systems in Greater Montreal for over 15 years. This field experience has taught us one essential thing: the majority of buildings are not ideal new constructions, but houses, duplexes and commercial buildings with existing infrastructure that must be respected, analyzed and optimized.

The ADD-ON Elios 36,000 BTU central heat pump with coil and cabinet fits perfectly into this approach. It doesn't aim to replace everything unnecessarily, but rather to radically improve energy efficiency and comfort by intelligently integrating into an existing system.

This model is particularly relevant for:

• Electric single-family homes in Montreal

• Duplexes and triplexes in Longueuil or Laval

• Rental properties on the South Shore

• Buildings exposed to cold and wind on the North Shore

With a heating capacity down to -30°C , this central heat pump is not a compromise: it is a robust solution, designed for real Quebec winters, not for theoretical conditions.

The Elios ADD-ON approach: integrate rather than rebuild

In a large proportion of the HVAC installation projects we undertake in Montreal and Laval , the ventilation ducts are still in excellent condition. Replacing them would represent a high cost, invasive work, and little added value for the client.

The Central-Elios ADD-ON was designed specifically for these situations:

• Replacing an aging central heat pump

• Adding a heat pump to an existing electrical system

• Hybrid configuration with retained electric backup

• Modernizing a central system without modifying the air distribution

The coil with cabinet (GCHMA36RBAS1) plays a key role here. It offers a rigid structure, improved sealing, and clean integration with existing plenums and ducts. This reduces air loss, improves flow consistency, and facilitates system balancing.

Feedback from the field

On the South Shore, we replaced an old central heating system that was over 20 years old in a duplex. The ductwork was properly sized, but overall efficiency had become very low. Thanks to the installation of a 3-tonne Elios ADD-ON , the client was able to keep their existing infrastructure, reduce construction costs, and see a significant decrease in their electricity consumption from the very first winter.

Actual heating and cooling performance: what it means in everyday life

The ADD-ON Elios 36,000 BTU central heat pump doesn't just boast high numbers. It's designed to maintain usable capacity when temperatures become critical , which is crucial in our climate.

Key Capabilities

• Rated power : 36,000 BTU (3 tonnes)

• Power at -15°C : 36,000 BTU

• Power at -8°C : 29,200 BTU

• Guaranteed operation down to -30°C

• SEER2 : 15.8

• HSPF2 : 7.9

• COP at -8 °C : 2.5

In practice, this translates to a truly efficient primary heating system during the winter, without prematurely switching to electric backup. For homeowners in Montreal or Longueuil, this means fewer energy consumption peaks and more consistent comfort, even during prolonged cold spells.

A point we always explain to our customers

A system can "operate" at low temperatures without necessarily being cost-effective. What matters is the amount of heat produced per kilowatt consumed . The Elios ADD-ON stands out precisely in this respect, particularly in temperature ranges where other systems become inefficient.

Inverter technology and HEAT+: precise regulation, not just on/off

The Central-Elios ADD-ON series incorporates advanced Inverter technology combined with HEAT+ mode , allowing continuous power modulation.

In our HVAC installations in Laval and on the North Shore, this technology offers very tangible advantages:

• A more stable indoor temperature, without sudden variations

• Better humidity control during the mid-season

• A reduction in mechanical wear related to frequent starts

• More linear and predictable electricity consumption

Unlike traditional 24V systems that operate on an on/off basis, bidirectional communication between indoor and outdoor components allows the heat pump to adapt in real time to the actual needs of the building .

A choice particularly suited to Greater Montreal

Why does this heat pump work so well in our region?

The climate of Greater Montreal imposes specific constraints:

• Long and sometimes extreme winters

• Rapid temperature variations

• Old buildings with existing mechanical constraints

The ADD-ON Elios central heat pump precisely addresses these realities. It is ENERGY STAR® and ENERGY STAR® Cold Climate certified , making it eligible for the LogisVert subsidy .

Currently, this configuration allows you to benefit from a provincial subsidy of up to $3,504 , a factor that we systematically include in our return on investment analyses.

Key technical details for a durable installation

At AirGreen, we know that it's the technical details that make the difference in the long run.

Essential specifications

• Exterior model : ESHMB36R2AN1

• Interior model with cabinet : GCHMA36RBAS1

• Refrigerant : R-454B (A2L)

• Piping : 3/8" (liquid) – 3/4" (gas)

• Airflow : up to 1,500 CFM

• Outdoor noise level : 64 dB(A)

• Power supply : 208-230 V, 1 phase

The choice of R-454B makes it possible to combine energy performance and compliance with current environmental standards, while integrating safety devices adapted to new requirements.

Safety, noise, and visual integration: often overlooked aspects

Integrated leak detection

The ADD-ON Elios heat pump is equipped with a refrigerant leak detection system. In the event of a fault, the compressor automatically shuts down, air continues to circulate, and a service alert is generated. This type of protection is particularly valuable in residential and multi-unit buildings.

Acoustic comfort

In dense neighborhoods of Montreal or Longueuil, outside noise is a real issue. Compared to a traditional central system that can reach 73 dB(A), the Central-Elios operates at around 65 dB(A) , which represents a significant difference for residents and the neighborhood.

Guarantee and long-term vision

The ADD-ON Elios central heat pump is offered with:

• 10 years on the compressor

• 10-year warranty on parts

• Labor warranty available as an option

In our experience, customers who choose this solution do so with a 10- to 15-year timeframe. The stability of inverter technology and the quality of manufacturing allow them to consider this investment with confidence.

Why entrust your project to AirGreen

Installing an ADD-ON central heat pump requires much more than simply connecting components. It involves:

• A precise analysis of existing conduits

• A rigorous calculation of thermal loads

• A meticulous commissioning

At AirGreen, we have completed this type of installation in Montreal, Laval, Longueuil, on the North Shore and the South Shore , in a wide variety of contexts. Our approach is based on:

• Clear and confirmed pricing before work begins

• Experienced refrigeration technicians specializing in central systems

• $5 million liability insurance

We know exactly when the ADD-ON Elios 36,000 BTU central heat pump is the optimal solution, and when another configuration would be preferable.
