The thermal comfort revolution: power, reliability and performance by MIDEA

At AirGreen , we believe that the comfort of your home or business should never depend on the whims of Quebec's climate. That's why we chose to offer the MIDEA ATOM X | 5 Ton Electric Furnace , a next-generation HVAC solution designed to meet the energy, ecological and comfort needs of today's families and businesses.

This high-end model combines Mini VRF Inverter technology with precision engineering , capable of providing stable heating even in extreme cold down to -30°C . In summer, the same unit provides constant and gentle air conditioning, even during heat waves of 51°C . It is a true technological feat designed for Montreal winters, Laval's shoulder seasons, or even the hot summers of the South Shore.

Intelligent design adapted to the Quebec climate

Mini VRF technology: intelligent and flexible comfort management

The Midea Atom X series represents a major advancement in the world of heating and cooling. Thanks to its Inverter Mini VRF (Variable Refrigerant Flow) technology, the furnace can power multiple indoor units —whether wall-mounted, cassette, ducted, or electric—while providing precise, individual temperature control in each zone.

This means a house, duplex, or commercial building can benefit from perfectly balanced multi-zone comfort , with stable and consistent temperatures in every room. No more fluctuations between floors, overheating in the living room, or overly cold bedrooms in the basement.

Each indoor unit communicates intelligently with the main system to adjust power, reducing power consumption and extending compressor life.

Certified and measurable performance

Exemplary energy efficiency

The MIDEA ATOM X 5 Ton Electric Furnace displays performance values ​​that place it among the best in its category:

• SEER2 (air conditioning efficiency): 20.0

• HSPF2 (heating efficiency): 10.1

• EER2 (instantaneous efficiency): 9.5

These figures reflect exceptional energy efficiency. The result: a lower electricity bill, quieter operation, and a minimal environmental footprint. ENERGY STAR Cold Climate certification confirms that this system is designed to operate efficiently even in northern climates.

Guaranteed heating down to –30°C

Thanks to its high-efficiency dual rotary compressor, the MIDEA ATOM X maintains full power down to –20°C , and continues to provide stable heating down to –30°C . This ensures consistent comfort, even during the harshest Montreal winters. In contrast, the system supports air conditioning temperatures of up to 51°C , an extremely wide operating range that makes it ideal for year-round use.

Sustainable, eco-responsible and silent engineering

R-454B Refrigerant: An Environmentally Friendly Choice

The Atom X series uses R-454B refrigerant, known for its low global warming potential (GWP 466) , which is nearly 80% lower than traditional R-410A. This new generation refrigerant combines superior energy performance with reduced environmental impact , making this model a sustainable choice for the long term.

R-454B also provides:

• better heat transfer for optimized performance,

• less pressure loss , therefore a constant flow,

• and increased efficiency in heat recovery .

At AirGreen, we always prioritize environmentally friendly HVAC solutions without compromising on comfort.

A quieter and more stable system

The MIDEA ATOM X has been designed to blend discreetly into your environment. With a noise level of just 60 dB(A) , even at full power, the system blends into everyday life without disruption. This discretion is combined with smooth operation without excessive vibration, thanks to the optimized compressor design and automatic fan speed management.

A system designed for simplicity and precision

Automatic refrigerant charging

No more long and complex manual procedures: the MIDEA ATOM X is equipped with an automatic refrigerant charging system . This innovation significantly reduces installation time and the risk of human error.
Once the tank is connected, the system calculates the required quantity and automatically adjusts the load, ensuring optimal performance from the first start-up.

Long range and flexible installation

The Atom X Series offers a communication distance of up to 2,000 meters (6,562 ft) between units, thanks to free-topology cabling and excellent interference protection .
It supports a total piping length of 984 ft , a height difference of 164 ft between units, and up to 9 indoor units connected to the same outdoor unit.
This level of flexibility allows our teams to install the system in buildings of all sizes—townhouses, condos, offices, restaurants, or retail—without compromising on performance.
