Outdoor unit
One compressor for the whole house. It supplies up to 3 heads and modulates from 10,248 to 28,500 BTU/h depending on what the rooms call for (NEEP).
Base pan heater
A heater keeps the outdoor unit’s base pan free of ice below 1 °C and during defrost (NEEP).
Refrigerant lines
One pair of lines per head.
Indoor heads
One head per room, each with its own remote and temperature. The combination is chosen in the “Zones” menu.
Control
Each zone is set separately, also from your phone.
Turn rooms on and off. Watch the power being shared.

A multi-zone solution truly adapted to the climatic realities of Quebec
At AirGreen Heat Pumps, Air Conditioning & Heating , we have been installing HVAC systems for over 15 years in Montreal , Laval , Longueuil , and on the North and South Shores. The LG Multi F LGRED R32 heat pump with a 24,000 BTU compressor perfectly meets the needs we encounter in the field: complexly configured homes, condominiums, duplexes, single-family homes with distinct zones, and buildings where optimizing outdoor space is crucial.
This dual-zone system allows two independent indoor units to be powered by a single outdoor compressor , while also offering the possibility of upgrading to a triple-zone configuration. In practice, this means precise temperature control, a reduced outdoor footprint, and a scalable solution designed for the long term.
Why the Multi F concept tangibly changes the occupant experience
In several projects completed by AirGreen in Rosemont , Ahuntsic , Laval-des-Rapides , and Brossard , we observed that heating and cooling needs vary significantly from room to room. A north-facing bedroom, a south-facing living room with windows, or a home office occupied all day cannot be treated uniformly.
The LG Multi F LGRED R32 system addresses this reality precisely:
-
Each indoor unit has its own temperature settings ;
-
The compressor adjusts its capacity using inverter technology , avoiding abrupt on/off cycles;
-
Air distribution is optimized thanks to automatic motorized flaps (horizontal and vertical).
The result: stable comfort, without unpleasant variations, even during the coldest winters or the hottest summers.
Actual heating performance, even at very low temperatures
A key concern for our customers in Quebec is winter performance. The LG Multi F LGRED R32 is designed to provide heating capacity down to -25°C , making it perfectly suited to the winters of Montreal , Laval , and the Montérégie region.
During recent installations in Villeray duplexes and semi-detached houses on the South Shore , we observed excellent thermal stability even during prolonged periods of intense cold. The available power remains sufficient to maintain comfort without excessive reliance on supplemental electric heating.
From a technical standpoint, the LGRED R32 compressor is associated with:
-
intelligent defrosting , reducing efficiency losses;
-
an integrated condensate tray heater , limiting ice buildup;
-
an extended operating range, validated for cold climates.
These elements make a tangible difference to energy consumption and long-term reliability.
Choosing R-32 refrigerant: efficiency and environmental responsibility
The switch to R-32 gas represents a significant evolution in the HVAC field. Compared to older refrigerants, it offers:
-
a reduced global warming potential ;
-
improved thermodynamic efficiency;
-
a lower refrigerant charge for an equivalent capacity.
In our projects in Longueuil and on the North Shore , this choice is often part of a comprehensive approach to energy improvement, particularly for owners wishing to maximize access to provincial LogisVert subsidies .
Technical configuration and compatibility of indoor units
Flexibility is one of the major advantages of this heat pump. The KUMXA241A compressor can be paired with several LG indoor unit models, both wall-mounted and compact, depending on the home's layout. This variety allows the system to be precisely adapted to architectural constraints such as low ceilings, load-bearing walls, and hard-to-reach areas.
In the field, our AirGreen teams always take the time to assess:
-
the distribution of thermal loads by zone;
-
the lengths of refrigeration pipes;
-
electrical constraints (220 V, MCA 24 A , MOP 30 A ).
This step is essential to ensure a compliant, efficient and durable HVAC installation.
Noise level and acoustic comfort
Another often underestimated aspect is noise. The outdoor compressor operates at a moderate noise level , well-suited to dense residential environments like Montreal . Inside, the wall units operate at very low levels in normal mode, which is particularly appreciated in bedrooms and home offices.
We have notably installed this system in multi-unit residential buildings where condominium regulations impose strict acoustic constraints: the feedback is very positive.
Professional installation: the AirGreen approach
A multi-zone heat pump requires careful installation. At AirGreen , we emphasize several key points:
-
wall or floor mount suitable for winter conditions;
-
precise management of drainage slopes;
-
careful insulation of the pipes to prevent losses and condensation;
-
complete commissioning with performance testing.
Our certified refrigeration technicians work daily in Montreal , Laval , Longueuil , on the North Shore and the South Shore , with a thorough knowledge of local standards and climatic realities.
Maintenance and durability
Like any HVAC system, longevity also depends on maintenance. We recommend:
-
regular cleaning of the filters of the indoor units;
-
an annual system check;
-
a visual inspection of the compressor before and after winter.
These simple actions help to preserve energy efficiency and reduce the risk of breakdowns in the long term.
Guarantee and peace of mind
The LG Multi F LGRED R32 heat pump is covered by a 10-year warranty on the compressor and parts . Labor is also covered for 6 years, straight from the distributor, and AirGreen can offer additional warranty options depending on the project, providing homeowners with added peace of mind.

What people ask us about multi-zone systems.
Can I heat one room and cool another at the same time?
No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.
What happens when every room calls for heat?
They share the outdoor unit’s capacity: 17,800 BTU/h at −8 °C, 22,000 at −15 °C.
How many heads can I connect?
Up to 3 on this outdoor unit. This product is configured for 2 heads.
How much is the LogisVert grant?
$2,136 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.
Is it ENERGY STAR certified?
Yes, cold climate, ID 3553131. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −25 °C.
Is it noisy?
Indoors, the reference head goes down to 29 dB(A). Outdoors, 55 dB(A): we place the unit away from bedroom windows.
Why a multi-zone instead of several wall units?
One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.
What does the warranty cover?
Our sheet lists 10 years on the compressor and 10 years on parts. AirGreen extended warranty: possible.
A multi-zone system is planned room by room. At your home.
We measure every room, draw the line route and choose the right head for each zone. The on-site estimate is free and the quote arrives within 24 h.
