LG Multi F MAX LGRED R32 Heat Pump | 3 Heads + 36000 BTU | Montérégie

BROCHURE

A high-end, multi-zone solution designed for residential and multi-unit buildings in Montérégie

At AirGreen , we have been installing multi-zone systems in real-world settings for many years: complex single-family homes, duplexes, triplexes, apartment buildings, local businesses, and professional offices. The LG Multi F MAX LGRED R32 heat pump – 3 heads – 36,000 BTU – falls squarely into this category of advanced technical solutions, designed to offer flexibility, efficiency, and stability in the demanding climate of Montreal, Laval, Longueuil, the North Shore, and the South Shore , including the entire Montérégie region .

This system allows up to three independent indoor units to be powered by a single outdoor unit, with intelligent power management tailored to the actual needs of each zone. This approach is particularly relevant when heating and cooling loads vary from one space to another, something we observe daily in the field.

Multi F MAX LGRED architecture: what this actually changes in an HVAC installation

A robust outdoor unit designed for the Quebec climate

The outdoor model KUMXA361A is based on a variable-speed scroll compressor inverter architecture, designed to operate over a wide temperature range. In practice, this translates to:

• Heating capacity maintained down to -25°C , a critical threshold for the Montérégie and North Shore regions.

• Precise power modulation, reducing on/off cycles

• Improved thermal stability in each zone, even during prolonged cold spells.

During our installations in semi-rural areas of Montérégie , this type of compressor makes a real difference: fewer fluctuations, fewer complaints related to comfort, and better controlled electricity consumption over the entire season.

R-32 refrigerant: technical choice and real impact

The system uses R-32 gas , a choice we are increasingly favoring at AirGreen for several concrete reasons:

• Reduced global warming potential (GWP) compared to older refrigerants

• Better volumetric efficiency, therefore less fluid required

• Compatibility with current and future environmental requirements

In practice, this also facilitates long-term HVAC maintenance and ensures a better lifespan for the installation.

Multi-zone management: true independence of spaces

Three indoor units, three distinct behaviors

The 3-zone configuration allows you to connect different compatible wall units or consoles (e.g., KNUAK091A, KNUAK121A, KNUAK181A , etc.), each with:

• Its own thermostat

• Its own airflow

• His own logic of demand

In a typical Montérégie home that we recently equipped, this allowed us to:

• A main zone heated continuously

• A guest room kept at a reduced temperature

• A home office with independent air conditioning in summer

Result: targeted comfort and measurable savings , without compromise.

Intelligent power distribution

The 36,000 BTU rated power is not rigidly allocated. The system dynamically adjusts the allocation according to the actual demand of the active zones. This logic is essential in buildings where not all rooms are occupied simultaneously, which is extremely common in our projects in Laval and Longueuil .

Key technical data useful in the context of installation

Without delving into theoretical values ​​disconnected from reality, here are the technical elements that directly influence our installation choices:

• Rated cooling capacity : 36,000 BTU

• Heating capacity maintained at low temperature thanks to LGRED technology

• Controlled external noise levels , important for densely populated residential areas

• Voltage 220 V , MCA and MOP compliant with local electrical requirements

• Built-in Wi-Fi , facilitating remote control and diagnostics

The piping diagrams, maximum permissible lengths and permitted elevation differences are particularly generous on this series, which gives us great design freedom during complex installations or advanced renovations.

Installation in Montérégie: what we systematically adapt

Building analysis prior to any final proposal

Before installing an LG Multi F MAX heat pump , we always analyze:

• The building's thermal envelope

• The actual volumes of each area

• Pipe passage constraints

• The acoustic limits of the neighborhood

• The existing electrical configuration

This step helps to avoid common mistakes: oversizing, poor distribution of zones, or disappointing performance during peak periods.

Distribution Unit Management (DUM)

On Multi F MAX systems, the correct use of the distribution units (BDUs) is crucial. At AirGreen, we pay particular attention to:

• Their internal positioning

• Component insulation

• Strict adherence to maximum lengths and heights

Poor management of these elements is one of the main causes of performance losses that we observe when taking over poorly designed installations.

LogisVert subsidy and actual profitability

At the time of writing, this system is eligible for a provincial LogisVert grant of up to $3,552 , subject to project and installation compliance. In the Montérégie region, this financial assistance significantly improves the return on investment, especially when replacing less efficient electrical systems.

We systematically support our clients in:

• Validation of eligibility

• Document preparation

• The technical compliance required by the program

Why entrust the installation to AirGreen

Choosing a multi-zone heat pump of this size requires more than just a simple connection. At AirGreen , we provide:

• Certified refrigeration technicians experienced with complex systems

• Real-world experience in residential, commercial, and multi-unit housing.

• Transparent pricing , confirmed before work begins

• $5,000,000 liability insurance

• A structured and accessible after-sales service

We operate daily in Montreal, Laval, Longueuil, on the North Shore and the South Shore , with a strong presence in Montérégie .

A suitable solution when comfort does not need to be uniform, but precise.

The LG Multi F MAX LGRED R32 Heat Pump | 3 heads | 36,000 BTU is particularly relevant when each space has its own unique thermal requirements. It's a solution we recommend when precision, stability, and flexibility are more important than standardized approaches.
