A central ADD-ON solution designed for Quebec's existing building stock

At AirGreen, much of our expertise lies in central installations in buildings not originally designed to accommodate a modern heat pump . It is precisely in this context that the Elios 36,000 BTU ADD-ON Central Heat Pump with coil and no cabinet truly shines.

In reality, in Montreal , Laval , Longueuil , and on both the North and South Shores , we frequently work on single-family homes, duplexes, triplexes, and multi-unit buildings equipped with an existing electric furnace or an aging hybrid system. Complete replacement of the central system is neither desired nor justified. The ADD-ON concept allows for the addition of a high-performance central heat pump while preserving the existing infrastructure.

The choice of a coil without a cabinet is not insignificant. It responds to very specific constraints:

• Limited height in the mechanical room

• Existing sheathing to be retained

• Access restricted during renovations

• The need to limit invasive procedures

In many projects, this format allows us to optimize space, reduce overall costs and, above all , make possible an installation that would otherwise be impossible .

A central heat pump truly adapted to the Quebec climate

One of the most important criteria for our customers remains heating performance in cold weather . Too often, central systems are installed without taking into account local climatic conditions, leading to excessive reliance on supplementary electric heating.

The ADD-ON Elios central heat pump was designed to operate down to -30°C , a threshold that corresponds to the actual winter conditions observed in Quebec. In practice, this means that the system continues to provide primary heating for most of the winter, without prematurely switching to electric resistance heating.

Thermal behavior observed under real-world conditions

During our installations:

• At -8°C , the heat pump maintains a heating capacity of approximately 29,200 BTU

• At -15°C , it retains its nominal capacity of 36,000 BTU

• At very low temperatures, the efficiency remains stable thanks to inverter modulation.

This progressive operation avoids short cycles, reduces wear on components and significantly improves the comfort felt in living spaces.

Inverter technology and intelligent power modulation

Unlike traditional on/off central systems, the Elios central heat pump relies on advanced Inverter technology . The compressor continuously adjusts its speed to precisely meet the building's actual needs.

In a residential or multi-unit dwelling setting, this offers several concrete advantages:

• More stable temperature in all rooms

• Reduction of gaps between floors

• Reduction in peak electricity consumption

• Quieter operation

In multi-level houses in Longueuil or on the South Shore , this modulation makes it possible to avoid the frequent problems of overheating upstairs and underheating in the basement, without constant manual intervention on the thermostat.

Coil-type pipe without a cabinet: a key flexibility in renovation projects

The A-frame coil without a cabinet is one of the most strategic elements of this model. As part of an add-on project, it allows for direct integration with:

• An existing electric furnace

• A plenary session already in place

• A network of pipes sized for central heating

This format reduces the overall height of the unit, which is crucial in basements with low ceilings, very common in Montreal and Laval . In some replacement projects, this allows us to avoid modifying the floor structure or completely redoing the ductwork.

Concrete example of ADD-ON installation

In a six-unit building on the North Shore , each unit was equipped with an individual electric furnace. The owner wanted to improve energy efficiency without interrupting rentals or undertaking major renovations. The installation of ADD-ON Elios central heat pumps with cabinetless coils allowed for:

• To add central air conditioning in each dwelling

• To reduce heating costs

• To preserve all existing facilities

The project was completed quickly, with minimal disruption to the occupants.

Humidity management and seasonal comfort

Thermal comfort isn't just about the temperature displayed on the thermostat. In summer, dehumidification plays a major role in the feeling of coolness. Thanks to its advanced communication between indoor and outdoor components, the Elios central heat pump fine-tunes its operation to optimize humidity removal.

Result :

• drier and more comfortable air

• Reduction of the feeling of heaviness

• Improved indoor air quality

In several residences in Montreal , this precise humidity management has improved comfort without excessively lowering the temperature, resulting in additional energy savings.

Essential technical data for a well-planned project

For property owners and managers who wish to understand precisely the installed equipment, here are the main characteristics of this model:

• Nominal capacity : 36,000 BTU (3 tonnes)

• Heating capacity down to : -30 °C

• Refrigerant : R-454B (new generation, A2L compliant)

• Piping : 3/8 – 3/4

• Outdoor noise level : approximately 64 dB(A)

• Power supply : 220 V

• ENERGY STAR® and ENERGY STAR® Cold Climate certified

• AHRI Number : 216760015

These parameters directly influence overall performance, eligibility for subsidies, and the longevity of the system.

Integrated safety and quiet operation

The ADD-ON Elios central heat pump incorporates refrigerant leak detection that continuously monitors the circuit. In case of a malfunction, the system:

• Automatically stops the compressor

• Maintains air circulation

• Send a service alert

This preventative approach is particularly appreciated in multi-unit residential buildings, where reliability and safety are priorities.

From an acoustic standpoint, the outdoor unit with horizontal discharge is designed to limit noise propagation, an important advantage in the dense residential areas of Montreal and Laval .

LogisVert subsidy and long-term savings

This model is eligible for the LogisVert provincial grant , which can reach $3,504 , depending on the project's configuration and location. At AirGreen, we incorporate this information from the design phase to maximize the project's profitability.

Our support includes:

• Eligibility analysis

• Preparing the required documents

• An installation that meets the program requirements

On several recent projects, the combination of the subsidy and energy savings has significantly reduced the net cost for owners.

Guarantee and lasting peace of mind

The ADD-ON Elios central heat pump is covered by a 10-year warranty on the compressor and parts , with the option to add an extended warranty as needed. This coverage is particularly reassuring for owners of long-term buildings, where equipment reliability is a key factor.

The AirGreen approach: much more than an installation

Installing an ADD-ON central heat pump requires a thorough building analysis , going far beyond simply choosing a model. At AirGreen, we systematically evaluate:

• The actual sizing of the needs

• Compatibility with existing equipment

• Mechanical and acoustic constraints

• Building occupancy habits

It is this rigorous approach, based on hundreds of installations in Montreal , Laval , Longueuil , North Shore and South Shore , that guarantees a reliable and lasting result.

Conclusion

The Elios ADD-ON Central Heat Pump | 36,000 BTU | -30°C | coil-free unit represents a coherent, high-performance solution perfectly suited to the realities of Quebec's housing stock. It improves comfort, reduces energy consumption, and modernizes an existing central system without excessive construction work.
