A multi-zone solution designed for Quebec's climate and the realities of modern homes

At AirGreen, we have been installing multi-zone systems for many years in a wide variety of settings: single-family homes in Montreal, duplexes in Laval, triplexes in Longueuil, newer condos on the South Shore, and older residences on the North Shore. The LG Multi F LGRED R32 heat pump with a 24,000 BTU compressor and up to three indoor units perfectly fits this reality: offering a high-performance, flexible, and sustainable solution when a single system needs to serve multiple living spaces.

This type of configuration is often chosen when occupants wish to air condition and heat several independent zones without multiplying the outdoor units, whether for aesthetic, noise, space or municipal regulation reasons.


Why choose an LG Multi F LGRED R32 multi-zone heat pump?

A comfort-by-zone approach, without compromise

Unlike a simple wall-mounted system, a multi-zone heat pump allows you to control each room or zone independently. In practice, this means:

  • A room kept at a cooler temperature at night

  • A comfortable lounge in the evening

  • A home office that is efficiently heated during the day

Each indoor unit adjusts its operation according to actual needs, which improves comfort and reduces unnecessary cycles.

One outdoor compressor for three indoor units

The KUMXA241A model can power up to three compatible indoor units while maintaining excellent operating stability. During our installations in Montreal and on the South Shore, this configuration is often chosen for:

  • Multi-story houses

  • Open-concept condos with adjacent enclosed rooms

  • Multigenerational housing

This approach limits the external footprint while maintaining a high degree of freedom in interior design.


Actual performance in heating and air conditioning

Reliable heating down to -25°C

The LGRED series is designed for cold climates. In Quebec's winter conditions, this makes a real difference. The variable-speed inverter compressor precisely adjusts its power according to heating demand, which allows for:

  • Stable heating during periods of extreme cold

  • Fewer temperature variations

  • A reduction in electricity consumption during milder periods

In several projects carried out by AirGreen in Laval and on the North Shore, this type of system has made it possible to reduce the dependence on electric baseboard heaters , while maintaining constant comfort throughout the dwelling.

Efficient and quiet air conditioning

With a nominal cooling capacity of 24,000 BTU , this system is perfectly suited to the hot and humid summers of Montreal and the Montérégie region. The indoor units offer:

  • A well-distributed airflow

  • Quiet operation, appreciated in bedrooms

  • Precise control thanks to built-in Wi-Fi


R-32 refrigerant: a responsible and efficient choice

Switching to R-32 refrigerant gas offers a significant advantage:

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

  • Better energy efficiency per unit load

  • Lower quantity of refrigerant required

In the context of current and future environmental standards, this choice contributes to the sustainability of the installation, a point often discussed with our clients in Montreal and Longueuil when selecting the system.


Key technical data of the LG Multi F LGRED R32 compressor

Without going into theoretical values ​​that are not very representative of real-world situations, here are the technical elements that have a concrete impact during HVAC installation :

  • Exterior model : KUMXA241A

  • Cooling capacity : 24,000 BTU

  • Maximum heating capacity at low temperatures : suitable for Quebec winters

  • Voltage : 208-230 V

  • MCA : 24 A

  • MOP : 30 A

  • Outdoor noise level : approximately 55 dB(A)

  • Maximum number of indoor units : 3

  • ENERGY STAR® and ENERGY STAR® Cold Climate certified

These characteristics serve as the basis for our precise calculation of loads and electrical sizing , in accordance with current standards.


HVAC installation: AirGreen's experience makes the difference

What we often see on the field

A poorly installed multi-zone heat pump can quickly lose its advantages: unbalanced flow, reduced heating performance, excessive noise, or unnecessarily high electricity consumption. At AirGreen, we learned, sometimes the hard way several years ago, that the success of a multi-zone system depends as much on the design as on the unit itself .

Our installation approach

For every project in Montreal, Laval, Longueuil, or on the South Shore, we:

  • Let's verify the exact compatibility of the indoor units.

  • Let's optimize the lengths of refrigeration pipes

  • Let's respect the maximum elevations between units

  • Let's adjust the load distribution by zone

  • Let's program and test each unit individually

This rigor explains why our multi-zone installations maintain their performance year after year.


LogisVert subsidy: a real financial advantage

At the time of writing, this system is eligible for the LogisVert provincial grant , with an amount of up to $2,136 , depending on the final configuration and applicable criteria. We systematically support our clients in:

  • Validation of eligibility

  • Preparing the required documents

  • Compliance of the facilities with the program requirements


Who is this system intended for?

The LG Multi F LGRED R32 24,000 BTU heat pump is particularly recommended for:

  • Owners wanting a centralized but zoned solution

  • Housing where outdoor space is limited

  • Residential or multi-unit dwelling buildings

  • Customers seeking a good balance between performance, reliability and environmental impact
