A central solution designed for the realities of Quebec and existing buildings

At AirGreen, we install central heat pumps in single-family homes, duplexes, and small apartment buildings throughout Montreal , Laval , Longueuil , and on both the North and South Shores . One common issue arises: many buildings already have a ductwork system in good condition, but their heating or cooling equipment is nearing the end of its lifespan. The MIDEA EVOX G3 | 1.5 T - R454B "ADD-ON" Central Heat Pump was specifically designed for this situation.

This ADD-ON system allows for direct integration into an existing central system, without major building modifications. Specifically, we are talking about a central forced-air heat pump capable of providing heating , cooling , and dehumidification , while respecting the space, electrical, and energy performance constraints specific to Quebec homes.

Actual performance in central heating down to -30°C

A system designed for Quebec winters

One of the most critical factors for our clients remains performance in extreme cold. The MIDEA EVOX G3 is Cold Climate certified, with heating capabilities down to -30°C . In our installations in Laval and on the North Shore, we have observed remarkable thermal stability, even during prolonged cold spells.

For this 1.5-tonne model, the nominal output of 18,000 BTU is maintained at -15°C , with a measured output of 15,200 BTU at -8°C . This effectively covers the heating needs of a well-insulated house or a centrally located dwelling without the need for constant supplemental heating.

Measurable energy efficiency

The numbers speak for themselves:

• SEER2: 16.1

• HSPF2: 9.5

• COP at -8 °C: 1.206

• ENERGY STAR® and ENERGY STAR® Cold Climate

In a recent project in Boucherville , a client switched from an old electric system to an ADD-ON MIDEA EVOX G3 central heat pump . The result: a reduction in annual heating consumption measured from the first full season, without compromising on comfort.

ADD-ON technology: integrate without rebuilding

Intelligent replacement of existing systems

The ADD-ON approach is based on a simple idea: keep what works. Ducts, air distribution, and sometimes even certain electrical components can be reused. This reduces:

• Installation time

• Labor costs

• Invasive interventions in the building structure

At AirGreen, we regularly use this approach in Montreal homes built between 1970 and 2000, where the ducts are often in excellent condition.

Dimensions and compatibility

The indoor unit ( MAAHE-H24B-AA ) boasts compact dimensions of 14.5 x 21 x 18 inches , making it easy to install in tight spaces. The outdoor unit ( MO1HE-H18B-2A ) is equally discreet, measuring 35.04 x 13.46 x 26.50 inches , and has an outdoor sound level of 56.5 dB(A) , an important consideration in densely populated residential areas.

R-454B refrigerant: a choice for the future

Ecological transition without compromise

The MIDEA EVOX G3 uses R-454B , a new-generation refrigerant with a low global warming potential. This choice reflects a commitment to long-term regulatory compliance, while also offering excellent thermal efficiency.

In our recent projects on the South Shore , this type of refrigerant also facilitates access to provincial subsidies , notably LogisVert , which currently amounts to $1,824 for this model (updated: November 26, 2025).

Intelligent air and comfort management

Constant airflow and filtration

With an airflow of up to 1,500 CFM , the EVOX G3 central heat pump ensures uniform air distribution throughout the building. It accepts high-performance filters, which improves indoor air quality—an often underestimated but crucial aspect for families and multi-unit buildings.

In a building in Longueuil , we corrected a recurring problem of rooms being too cold upstairs thanks to a precise adjustment of the airflow, made possible by the intelligent regulation of the system.

Built-in WiFi and precise control

The built-in Wi-Fi allows for remote control via a compatible thermostat. For our customers, this means:

• Precise programming of heating and air conditioning schedules

• Rapid adjustments in case of weather changes

• Energy consumption monitoring

Professional installation: what we learned in the field

Common mistakes to avoid

Over the years, we have observed several common mistakes when installing ADD-ON central systems:

• Undersized capacity

• Poor fit to existing conduits

• Neglect of electrical calibration (MCA: 16A , MOP: 20A )

At AirGreen, each project begins with a complete analysis: thermal load, condition of the ducts, electrical constraints and usage habits of the occupants.

A concrete case in Montreal

In a bungalow in East Montreal , the client was hesitating between completely replacing their central heating system or opting for an add-on solution. After evaluation, the MIDEA EVOX G3 1.5 T central heat pump proved to be the perfect fit. The installation was completed in one day, with immediate commissioning and no prolonged interruption of indoor comfort.

Guarantee and peace of mind

The standard warranty offered on this model is clear:

• 12 years on the compressor

• 12 years on parts

• 0 year on labor (extended warranty available)

At AirGreen, we systematically offer additional warranty options to ensure comprehensive protection for installation and long-term operation.
