LG Multi F MAX LGRED R32 Heat Pump | 2 Heads + 36000 BTU | Montérégie

A multi-zone solution designed for the residential and multi-unit realities of the Montérégie region

At AirGreen Heat Pumps, Air Conditioning & Heating , we have been installing multi-zone systems for many years in a wide variety of settings: single-family homes, duplexes, triplexes, new condos, major renovations, and multi-unit buildings. The LG Multi F MAX LGRED R32 | 2 Heads + 36,000 BTU Heat Pump is one of the solutions we recommend when flexibility, winter performance, and precise comfort control are top priorities, particularly in the Montérégie region , Longueuil , the South Shore , and as far north as the South Shore .

This system is based on a simple logic: a high-performance outdoor unit capable of powering several independent indoor units, while maintaining excellent energy efficiency, even during periods of intense cold typical of the Quebec climate.

Understanding the Multi F MAX architecture: why this system stands out

The LG Multi F MAX LGRED R32 is not a typical wall-mounted heat pump. It is an advanced multi-zone system, designed to distribute heating and cooling power precisely where it is needed.

A robust and intelligent outdoor unit

The KUMXA361A outdoor unit offers a nominal capacity of 36,000 BTU , with an operating range that remains stable down to -25°C in heating mode . In practice, this means the system continues to provide reliable comfort even during the prolonged cold spells we regularly experience in Montreal , Laval , Longueuil , and the Montérégie region .

Thanks to LGRED technology combined with R-32 gas , this heat pump offers:

• Improved seasonal energy efficiency

• A reduction in the environmental burden

• Increased performance stability in extreme conditions

The electrical parameters, current management (MCA 33 A, MOP 40 A) and internal design are suitable for serious residential installations, without compromising on safety or durability.

Two zones today, up to five tomorrow

Although this configuration is shown with 2 indoor units , the system allows for up to 5 zones in total. This scalability is particularly advantageous in projects where:

• A renovation is planned in several phases

• A basement or secondary dwelling will be created at a later date.

• The owner wants to maintain room for expansion.

We have installed this type of configuration in several properties on the South Shore , where needs are evolving rapidly with family or rental projects.

Indoor units: targeted comfort, precise control

One of the major advantages of a multi-zone system lies in the independent management of each space . Compatible indoor units (including the KNUAK , KNUAB and KNMAB series) allow the power, airflow and airflow direction to be adapted according to the actual use of each room.

A comfort that is noticeable on a daily basis

In the residences we have equipped in Boucherville , Saint-Hubert and Saint-Lambert , the occupants quickly notice:

• A more stable temperature

• Fewer abrupt variations between rooms

• A reduction in overheated or underheated areas

The internal noise level , which can go down to around 29 dB(A) depending on the model chosen, makes these units perfectly suited for bedrooms, home offices and open living spaces.

Air direction and diffusion quality

Automatic motorized louvers , both horizontal and vertical, ensure even air distribution. This limits direct drafts, an often overlooked but essential point for real comfort, especially during prolonged heating.

Energy efficiency: beyond the numbers, real savings

The seasonal efficiency values ​​announced for this system are high, but at AirGreen , we always insist on the concrete interpretation of this data.

What this means for a homeowner in Montérégie

In real-world projects that we have followed over several heating seasons:

• Electricity consumption is more stable

• Demand peaks are better controlled.

• Comfort is maintained without frequent recourse to supplementary sources

The high COP at -8°C indicates the system's ability to produce more heat per kilowatt consumed, even when the outside temperature drops. This is a key factor for homeowners concerned about their long-term operating costs.

HVAC installation: a determining factor often underestimated

A system like the LG Multi F MAX LGRED R32 doesn't tolerate approximations. The quality of the HVAC installation directly influences the performance, reliability, and lifespan of the equipment.

Refrigeration network management

Adherence to maximum pipe lengths, permitted elevation differences, and refrigerant distribution is essential. In multi-story buildings or multi-unit dwellings, we pay particular attention to:

• The location of the outdoor unit

• The routing of the main and secondary pipes

• Reducing pressure losses

These elements are crucial to ensuring that each indoor unit receives the intended capacity, without imbalance.

An approach tailored to each building

Every installation we carry out in Montreal , Laval , Longueuil , or on the South Shore begins with a precise analysis of heating and cooling needs, building configuration, and occupancy patterns. This approach allows us to fully exploit the potential of an advanced multi-zone system.

Concrete scenarios encountered by AirGreen
