A central heat pump designed for Quebec's climatic realities

At AirGreen , we have been installing central heat pump systems long enough to know that a product is only truly relevant if it meets the specific requirements of buildings in Greater Montreal , Laval , Longueuil , the North Shore , and the South Shore . The MIDEA EVOX G3 | 3 T R454B "ADD-ON" Central Heat Pump fits perfectly into this framework: a central system designed to replace or supplement existing heating, while offering consistent performance down to -30°C , without compromising energy efficiency or long-term reliability.

In practice, this model is particularly sought after by homeowners who want to modernize a house equipped with an older forced-air system or a gas furnace, without completely rewiring the ductwork. We have installed this central heat pump in single-family homes, duplexes, and even small apartment buildings, where the installation flexibility makes a real difference on the job site.

Heating and air conditioning performance: figures that really matter

The MIDEA EVOX G3 3 tonnes (36,000 BTU) is not just a product that looks good on paper; its performance translates concretely into everyday use.

Heating in cold climates

• Heating capacity down to -30°C , suitable for the harshest Quebec winters

• Power at -15°C: 36,000 BTU , allowing for stable comfort even during prolonged cold spells

• COP at -8°C: 1.93 , a clear indicator of solid energy efficiency in real-world conditions

During an installation carried out by our team on the North Shore , in a house built in the 1990s with an existing ductwork system, the client noticed a significant reduction in the use of supplemental electric heating, even on nights as low as -20°C. This is exactly the type of result we look for when we recommend an ADD-ON central heating system.

Stable and quiet summer air conditioning

• Cooling capacity: 36,000 BTU

• SEER2: 18.0 , demonstrating excellent seasonal efficiency

• EER2: 12.0 , guaranteeing consistent performance even on days of sustained heat

In urban areas like Montreal or Longueuil , where residential density requires particular attention to noise, the outdoor sound level of 62.5 dB(A) is a feature appreciated by our clients, especially when a neighbour is close.

Intelligent technical design: designed for installation and durability

A truly adaptable central architecture

The MIDEA EVOX G3 stands out for its modular and compact design, facilitating the replacement of existing systems:

• Width equivalent to several old furnaces

• Installation possible in vertical ascending, vertical descending or horizontal

• Compatible with so-called "low-boy" configurations when height is limited

In practice, this means fewer structural modifications, fewer surprises during installation, and better cost control for the customer.

Air management and indoor comfort

The indoor unit is designed to provide a stable airflow, even when the ducts are under stress:

• Airflow up to 1,500 CFM

• Automatic adaptation to static network pressure

• Compatible with high-efficiency filters (up to MERV 13)

In several projects carried out in Laval , we corrected recurring problems of areas that were too hot or too cold simply by adapting the airflow, without having to redo the entire duct network.

R-454B refrigerant: a consistent choice for today and tomorrow

The MIDEA EVOX G3 central heat pump uses R-454B refrigerant , classified A2L , known for its reduced global warming potential compared to previous generations. This choice is not insignificant:

• Reducing the environmental footprint

• Compliance with new North American standards

• Improved regulatory sustainability of the system

For our clients in Greater Montreal , this means an investment that remains relevant in the long term, both environmentally and from a regulatory perspective.

Key technical data for the 3-tonne model

• Exterior model : MO1SE-H36B-2A

• Interior model : MAAHE-H36B-BA

• AHRI Number : 216623524

• Voltage : 220 V

• MCA : 29 A | MOP : 30 A

• Piping : 3/8 – 3/4

• External dimensions : 38.58 x 16.34 x 38.39 in

• Interior dimensions : 17.5 x 21 x 23.5 in

These features, combined with a robust design, explain why we favor this model in demanding residential projects.

LogisVert subsidy: a concrete financial advantage

At the time of writing, the MIDEA EVOX G3 | 3 T R454B "ADD-ON" Central Heat Pump is eligible for a $3,504 LogisVert provincial grant . In several cases we have handled in Montreal and on the South Shore , this financial assistance has made the transition to a central heat pump much more accessible, while significantly improving the building's energy performance.

Reliability and guarantees: an unambiguous approach

Peace of mind is an integral part of our role at AirGreen . This model benefits from a robust warranty program:

• 12 years on the compressor

• 12 years on parts

• Additional guarantees may be available depending on the project context.

We have observed, on our previous installations of Midea systems, a remarkable consistency in manufacturing quality, which is reflected in the low frequency of corrective interventions after installation.

Why entrust the installation to AirGreen?

Installing an ADD-ON central heat pump requires much more than a simple connection. Each project requires:

• A detailed analysis of the building and existing ducts

• Rigorous sizing based on actual loads

• An installation that complies with Quebec's electrical and mechanical standards

At AirGreen , our certified refrigeration technicians work daily in Montreal , Laval , Longueuil , and on both the North and South Shores , using a methodical and transparent approach. We always provide a clear quote before starting any work, with no surprise adjustments afterward.

Conclusion

The MIDEA EVOX G3 | 3 T R454B "ADD-ON" Central Heat Pump represents a coherent central solution for homeowners seeking reliable heating in cold climates , efficient air conditioning , and a smart energy transition , while retaining their existing infrastructure.
