Why the MIDEA ATOM X 4 Tonnes is a strategic choice for residential and commercial properties in Greater Montreal

At AirGreen, we know that every customer needs a central heat pump that can meet Quebec's climate challenges while providing maximum energy efficiency, installation flexibility, and lasting comfort. This is exactly what the MIDEA ATOM X 4 Tonnes offers, a new generation multi-zone mini VRF system, specially adapted to the thermal requirements of Montreal, Laval, Longueuil, the North Shore , and the South Shore .

In this article, we share our expertise, our real-life experiences in the field, and all the essential technical specifications to guide you in your installation decision.

Power adapted to the needs of large spaces

With a cooling capacity of 48,000 BTU and a heating performance down to -30°C , this heat pump is designed to cover large volumes, typically in:

• Large residences

• Neighborhood shops

• Professional offices

• Intergenerational or multi-family homes

Its 4-ton format makes it a leading choice for properties requiring a reliable central system , without compromising between performance and energy consumption.

DC Inverter technology for sustainable energy savings

The DC inverter compressor allows for fine modulation of power according to actual needs. Result:

• Reduced power consumption by up to 30% compared to traditional systems

• A more stable and uniform interior temperature

• Fewer start/stop cycles, extending compressor life

These elements result in a SEER2 value of 17.0 , an HSPF2 of 9.4 , and an EER2 of 10.3 , which places this unit among the most efficient in its class, certified ENERGY STAR® , including for cold climates.

Reliable operation even in extreme conditions

Thanks to the use of the new R-454B refrigerant, the MIDEA ATOM X operates down to -30°C in heating mode and up to 52°C (125°F) in cooling mode. This feature is crucial for our customers in Quebec, where temperature variations are particularly marked.

As HVAC specialists in Montreal , we have installed this model in several properties on the South Shore and the North Shore. We have noted its reliability in periods of intense cold , with consistent performance even during nights at -28°C.

Exceptional installation flexibility

Extended piping length to fit any configuration

• Total piping length: up to 984 feet (300 m)

• Maximum height difference between units: 164 feet

• Up to 49 feet between indoor units

This flexibility allows for installation in multi-story buildings, sloping houses, or atypical configurations that we frequently encounter in Laval neighborhoods or older residences in Longueuil.

Compatibility with multiple indoor units (VRF IDUs)

The ATOM X outdoor unit can be paired with up to 6 types of indoor modules , including:

• Four-track cassette

• Compact cassette

• Low or medium static pressure ducts

• Wall-mounted (perfect for basements or offices)

• Vertical unit type central furnace (air handler)

Each room can be controlled independently or centrally , allowing total customization of comfort.

Quick and secure installation without soldering

The absence of welding is a major advantage for the speed, safety and cleanliness of the installation. At AirGreen, our technicians particularly appreciate this feature which allows:

• Faster installation

• Less risk of fire or sparks

• A clean intervention, with no impact on the rest of the house

Advanced Features: Built-in WiFi, Leak Protection, Auto-Charging

WiFi included

You can control your system remotely , adjust temperatures room by room and track energy consumption in real time.

Refrigerant leak detection

The system has automatic protection in case of leak detection. A cut-off device (optional) prevents refrigerant from leaking into the interior space.

Automatic refrigerant charging

No more dosing errors. The system automatically manages the required amount of refrigerant, reducing the risk of human error.
