A central ADD-ON solution designed for the realities of Quebec

In the context of residential and commercial central heating in Quebec , ADD-ON systems occupy a strategic position. They allow for the modernization of an existing installation—often electric or hybrid—without replacing the entire ductwork or the main equipment. The Elios 24,000 BTU ADD-ON central heat pump with coil and cabinet fits perfectly into this framework: a solution designed for Montreal, Laval, Longueuil, the North Shore, and the South Shore , where buildings have highly varied configurations and very real technical constraints.

At AirGreen , we have been installing this type of system in single-family homes, duplexes, apartment buildings, and light commercial buildings for over 15 years. Our field experience allows us to affirm that this Elios ADD-ON version meets a specific need: adding a high-performance central heat pump, capable of heating down to -30°C, while maintaining a functional existing infrastructure .

Understanding the Elios ADD-ON concept in a central system

What is an ADD-ON system?

An add-on system is designed to be integrated into an existing central heating system, typically consisting of a network of ducts and an existing heating source (electric baseboard heaters, electric furnace, or other). The role of the add-on heat pump is to provide:

• The main heating source for most of the year

• Central air conditioning during the summer season

• A complementary function with the existing heating source during extreme cold.

In the case of the Elios ADD-ON 24,000 BTU , the system is optimized for electric or hybrid integration, without compromising on winter performance.

The role of the coil WITH cabinet

The coil with cabinet is a major advantage in many installations completed by AirGreen in Montreal and on the South Shore . This format offers:

• Increased mechanical protection of the coil

• A cleaner and more structured integration into mechanical rooms

• Improved compatibility with certain existing central systems

• A more stable and durable installation over time

In older homes, particularly in Laval or Longueuil , this type of configuration reduces the necessary adjustments and limits corrective work.

Technical performance adapted to harsh winters

Heating capacity down to -30°C

One of the key strengths of this Elios central heat pump is its ability to efficiently heat down to -30°C , an essential factor for Quebec's climate. Specifically:

• Rated power : 24,000 BTU

• Power at -8°C : approximately 19,700 BTU

• Power at -15°C : approximately 21,000 BTU

In projects carried out by AirGreen on the North Shore , this performance stability makes it possible to significantly reduce the use of auxiliary heating, even during periods of sustained cold.

Inverter technology and intelligent modulation

The inverter technology integrated into the Elios system allows for precise capacity modulation according to the building's actual demand. Unlike traditional on/off systems:

• Electricity consumption is better controlled

• The cycles are longer and more stable.

• Thermal comfort is constant

• Mechanical wear is reduced

In several apartment buildings in Montreal , we have observed a clear improvement in the comfort perceived by occupants after replacing old central systems with this Elios ADD-ON solution.

Energy efficiency and compliance with standards

Performance indicators

This central heat pump boasts solid energy performance:

• SEER2 : High for a central ADD-ON solution

• HSPF2 : efficient in seasonal heating

• COP at -8°C : remarkable performance in winter conditions

• ENERGY STAR® and ENERGY STAR® Cold Climate : Compliance confirmed

These indicators play a key role in eligibility for grant programs, including LogisVert in Quebec.

R-454B refrigerant: safety and future

The choice of R-454B meets current environmental requirements while also offering:

• A better GWP profile than older refrigerants

• A2L compatibility with integrated leak detection

• Increased safety thanks to integrated sensors that stop the compressor in case of a malfunction

In our AirGreen installations, this point is systematically explained to customers, as it directly influences the longevity and regulatory compliance of the system.

Actual installation: what we observe in the field

Typical case in Longueuil

In a 1980s bungalow in Longueuil , the client wanted to keep their existing ductwork and supplemental electric heating. The installation of the ADD-ON Elios 24,000 BTU central heat pump with cabinet allowed for:

• Integration without major modifications to the conduits

• A significant reduction in electricity consumption in winter

• Uniform central air conditioning in the summer

• An external noise level that is controlled, at approximately 60 dB(A)

Points to consider during installation

Our experience has taught us that certain elements must be rigorously checked:

• Actual dimensions of the building and ducts

• Pipe length and diameter 3/8 – 3/4

• Available electrical capacity (220V, MOP 20A)

• Optimal placement of the outdoor unit to minimize noise

These checks are an integral part of the AirGreen method, whether in Montreal, Laval or on the South Shore .

Maintenance and durability of the system

A high-performing central add-on system remains dependent on regular HVAC maintenance . We recommend:

• A full annual inspection

• Cleaning the internal and external coil

• Checking the electrical connections

• Airflow control (CFM)

In the installations we have been monitoring for several years, this rigor helps to maintain initial performance and avoid costly breakdowns.

Guarantees and peace of mind

The ADD-ON Elios central heat pump is covered by:

• 10 years on the compressor

• 10-year warranty on parts

• 0 year on labor (additional warranty option available)

At AirGreen, we always clearly explain these elements before installation, so that the customer understands precisely what is covered and what can be added for increased protection.

Why choose AirGreen for this Elios system?

Choosing AirGreen for the installation of this ADD-ON Elios central heat pump means:
