A central heat pump designed for real Quebec winters, not theoretical conditions.

At AirGreen, we've been installing and maintaining central HVAC systems for many years, and one thing is clear: in Quebec, equipment can't be evaluated solely on a technical specification sheet. The real questions arise in January , when the temperature drops below -20°C , the wind exacerbates heat loss, and the system must maintain comfort 24 hours a day , without instability or excessive energy consumption.

The CANAIR R410A ADD ON Central Heat Pump | 48000 BTU – Cased Coil is one of those solutions that we recommend precisely because it was designed to work in the Quebec climate , as it is actually experienced in Montreal, Laval, Longueuil, on the North Shore and the South Shore .
This is a 4-tonne add-on central system, intended for both replacement projects and complete new HVAC installations, where the objective is clear: to heat efficiently in winter, cool stably in summer, and ensure long-term reliability .

An ADD-ON design that meets the constraints of existing buildings

Understanding the ADD ON principle in a real-world context

In practice, an ADD-ON system means much more than simply assembling units. It's an intelligent approach that enables:

• Integration with an existing electric furnace

• Preserving an existing network of conduits

• A reduction in structural work

• An adaptation for mechanical rooms of limited dimensions

At AirGreen, we regularly encounter this type of configuration in homes in Laval or Longueuil , where mechanical space doesn't allow for the installation of bulky or top-discharge systems. The cased coil format of the indoor coil allows for clean integration without compromising airflow or accessibility for HVAC maintenance.

Installation flexibility and mechanical versatility

The CANAIR ADD ON central heat pump offers great installation flexibility:

• Upward vertical configuration

• Vertical downward configuration

• Horizontal configuration

• Compatible with multiple duct orientations

This flexibility is essential in single-family homes, duplexes and multi-unit dwellings on the South Shore , where each mechanical room presents unique constraints.

A heating capacity that can actually be used in cold climates

Performance measured where it counts

A figure of 48,000 BTU may seem impressive, but what makes the difference in the field is the capacity maintained at low temperatures .
This model is distinguished by:

• Functional heating down to -30°C

• Maintains approximately 99% of capacity at -20°C

• Available power of approximately 40,000 BTU at -15°C

• COP measured at -8 °C: 11.83

In several projects carried out by AirGreen on the North Shore , these characteristics have made it possible to significantly reduce the activation of auxiliary electrical elements, resulting in better thermal stability and more predictable energy consumption .

Stable behavior even in extreme cold.

Unlike some systems that quickly lose efficiency when the temperature drops, this central heat pump maintains modulated operation, without aggressive short cycles. The result:

• more constant indoor temperature

• Fewer variations felt from one room to another

• Less mechanical stress on the compressor

For homeowners in Montreal , especially in open-concept or multi-story houses, this behavior is a tangible daily advantage.

Controlled acoustic comfort, both indoors and outdoors

A central system often operates for several hours a day. Noise therefore becomes a determining factor in the medium and long term.
The CANAIR R410A ADD-ON central heat pump includes:

• Inverter technology with progressive modulation

• A constant flow ECM engine

• Intelligent static pressure management

• An external noise level of approximately 64 dB(A) for the 4-tonne format

In practice, this translates into discreet operation, both outdoors and at the level of indoor distribution grids. In dense residential areas of Longueuil or Laval , this aspect is often crucial for long-term satisfaction.

Essential technical data for a successful HVAC installation

For savvy homeowners, property managers, or building professionals, here are the key elements to consider:

• Nominal capacity : 48,000 BTU (4 tonnes)

• Refrigerant : R-410A

• Voltage : 220 V

• MCA : 40 A

• MOP : 50 A

• Refrigeration piping : 3/8 – 3/4

• External dimensions : 37.48 x 16.34 x 52.48 in

• Interior dimensions (coil) : 21 x 21 x 24 in

• Airflow : suitable for high-capacity central networks

• WiFi : optional, depending on the chosen configuration

At AirGreen, these parameters are always validated beforehand to avoid any electrical or hydraulic undersizing, a problem that is still too frequent in poorly planned HVAC installations.

What AirGreen's field experience reveals about this type of system

Common errors that we regularly correct

Even with a good product, certain errors can compromise performance:

• Poorly sealed pipe network

• Poor airflow distribution

• Inappropriate or incorrectly positioned thermostat

• Lack of balancing after installation

• Underestimation of electricity needs

These problems do not always appear immediately, but in the medium term lead to a decrease in comfort and an increase in operating costs.

Our AirGreen approach to central systems ADD ON

Our methodology is based on:

• A complete analysis of the building , not just the surface area

• An assessment of actual heat losses

• Precise adjustment of flow rates after commissioning

• Functional tests in heating and air conditioning

• A clear explanation of how it works to the customer

In a recent project on the South Shore , this approach made it possible to optimize an existing central system without increasing the installed capacity, while significantly improving comfort on the upper floors.

HVAC maintenance, durability and warranties

The CANAIR R410A ADD ON central heat pump is designed for simplified maintenance :

• Quick access to components

• Easy-to-replace filter

• Corrosion-resistant aluminum coil

• Clear organization of electrical components

Regarding guarantees:

• 10 years on the compressor

• 10-year warranty on parts

• Labor not included , with the option of an extended warranty.

At AirGreen, we recommend HVAC maintenance every 12 to 18 months , especially to preserve heating performance and maintain stable efficiency over several years.
