Outdoor unit
One compressor for the whole house. It supplies up to 8 heads and modulates from 12,420 to 56,500 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.
One outdoor unit supplies every head: when several rooms call at once, they share its capacity. Pick an outdoor temperature.

A multi-zone HVAC solution designed for complex buildings in Quebec
At AirGreen, we work daily with owners of plexes , multi-unit residential buildings, intergenerational residences, and light commercial buildings in Montreal , Laval , Longueuil , on the North Shore and the South Shore . They all share a common need: an HVAC system capable of providing precise zone control , reliability in cold climates , and intelligent energy management , without multiplying the number of outdoor units.
The LG MULTI F MAX R32 7-Head Heat Pump – 60,000 BTU compressor – perfectly meets this need. This high-capacity, multi-zone system can power up to 7 indoor units (8 maximum) from a single outdoor unit, while maintaining stable heating and cooling performance. We regularly install it in projects where flexibility and technical planning make all the difference.
Why the LG MULTI F MAX stands out on the field
A truly usable multi-zone architecture
Unlike many multi-split systems limited by pipe length or height difference, the LG MULTI F MAX R32 offers exceptional design freedom . In multi-story buildings or buildings with complex layouts, this flexibility allows for optimal placement of indoor units without compromising performance.
From a technical standpoint, the system accepts:
-
A total length of piping that can reach nearly 476 ft
-
Significant height differences between the outdoor unit and the indoor units
-
The use of distribution boxes for a balanced distribution of the refrigerant
These parameters, which we control during our calculations and installation plans, are essential to avoid capacity losses and ensure long-term sustainability.
A capacity adapted to local climatic realities
With a rated output of 60,000 BTU , this system is designed to efficiently serve several distinct zones, each with its own heating requirements. In practice, we have installed it in:
-
Triplexes with one apartment per floor
-
Multi-unit houses with home offices
-
Small shops combining open spaces and closed offices
In terms of heating, capacity remains robust even when temperatures drop, which is crucial in the Quebec context. At -8°C , available power remains high, reducing reliance on supplemental electric heating.
R-32: a coherent technical and environmental choice
The R-32 refrigerant offers a tangible advantage, not just a marketing gimmick. Compared to previous generations, it offers:
-
A lower global warming potential
-
Improved thermal efficiency
-
Reduced fluid charge for the same capacity
For our clients concerned about their environmental footprint, particularly in projects eligible for certain provincial subsidies , this choice is part of a responsible and sustainable HVAC approach.
Key technical data mastered by our teams
When we propose this system, we analyze each project based on specific parameters:
-
Air conditioning capacity : 60,000 BTU
-
Areas served : 7 zones (8 maximum)
-
Electrical voltage : 220 V
-
MCA : 34 A
-
MOP : 40 A
-
Outdoor noise level : 58 dB(A)
-
Gas : R-32
-
Built-in Wi-Fi
-
Warranty : 10 years compressor, 10 years parts, 6 years labor straight from the distributor (extension possible)
These elements are systematically validated with the existing electrical infrastructure, in collaboration with the project electrician, in order to avoid any unpleasant surprises during commissioning.
Choosing internal units: a real strategy, not a coincidence
One of the strengths of the LG MULTI F MAX lies in the diversity of compatible indoor units: wall-mounted, console, cassette, and ducted. At AirGreen, we never select these units randomly.
A concrete example in Longueuil
In a three-story residential building, we combined:
-
Wall units in the bedrooms
-
A discreet cassette in the common area
-
A ducted unit for a closed office space
Result: uniform comfort , very low noise levels (up to 29 dB(A) inside depending on the model), and independent zone management which reduces conflicts between occupants.
What we learned on the ground
Common mistakes to avoid
Our experience has shown us that problems with multi-zone systems rarely originate from the equipment itself, but rather from:
-
Poor overall sizing
-
Inadequate allocation of charges by zone
-
Poorly optimized pipe lengths
-
Lack of a centralized control strategy
That is why we always integrate a detailed HVAC design phase, including the calculation of thermal loads and the planning of piping routes.
Maintenance and follow-up
A system of this size requires structured HVAC maintenance :
-
Periodic pressure checks
-
Cleaning of filters and heat exchangers
-
Wi-Fi and control settings update
-
Preventive diagnosis before the heating season
Our maintenance contracts in Montreal , Laval and on the South Shore help to preserve performance and extend the life of the system.
Why entrust the installation to AirGreen
Choosing this type of heat pump without an experienced team is an unnecessary risk. At AirGreen, we provide:
-
Certified refrigeration technicians specializing in multi-zone systems
-
$5 million liability insurance
-
Complete transparency on costs before work begins
-
A thorough knowledge of local standards and manufacturers' requirements
We have installed LG MULTI F MAX systems in very diverse contexts, from high-end residential to multi-unit dwellings, always with the same approach: precision, rigor and durability.
A coherent solution for demanding projects
The LG MULTI F MAX R32 7-Head Heat Pump | 60,000 BTU is clearly designed for projects where a simple residential system is no longer sufficient. It combines:
-
High power
-
Exceptional installation flexibility
-
Advanced zone control
-
Energy efficiency adapted to Quebec

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: 42,000 BTU/h at −8 °C, 46,000 at −15 °C.
How many heads can I connect?
Up to 8 on this outdoor unit. This product is configured for 7 heads.
How much is the LogisVert grant?
$2,100 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, ID 3621277. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −16 °C.
Is it noisy?
Indoors, the reference head goes down to 29 dB(A). Outdoors, 58 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.
