LG TripleZone MULTI F R32 Heat Pump | 36000 BTU Compressor

When three zones need to remain comfortable, without compromising on control or fuel consumption

In Greater Montreal, the reality of homes is rarely "simple." A glass-fronted ground floor that heats up too quickly in the summer, an upper floor that becomes drier in the winter, a basement that stays cool even in July, or a duplex where each level operates at its own pace: these are scenarios we see every week. This is precisely where a multi-zone heat pump becomes a very tangible comfort tool—and where the LG TripleZone MULTI F R32 Heat Pump | 36,000 BTU Compressor (outdoor unit KUMXB361A ) positions itself as a particularly well-suited solution.

At AirGreen , we've observed that multi-zone systems are often chosen for "good reasons" but installed for "bad reasons" when the time isn't taken to properly define the zones. A system like this isn't just about "adding three heads." It's about stabilizing a home by taking real-life conditions into account: room occupancy, sunlight, air circulation, humidity, and how a house behaves at -10°C or on a 32°C day.

This unit features an inverter-driven logic designed to modulate power, R-32 refrigerant, built-in Wi-Fi , and an architecture designed to power 3 zones (with the possibility of up to 4 zones depending on the configuration). In practice, this means more precise control, fewer fluctuations, and above all, more stable comfort in the neighborhoods of Montreal , Laval , Longueuil , as well as on the North and South Shores , where housing types and exposure vary considerably.

Why the “TripleZone” format is changing the way a house is heated and cooled

Multi-zone systems are often described as a luxury. In our daily lives, they are primarily a logical solution for homes where a single distribution point is insufficient to balance the overall sound.

With a well-designed TripleZone configuration, you gain on several levels:

• Room-by-room control , without having to "over-air condition" one area to correct another.

• More consistent comfort , especially in multi-level houses and plexes with rooms at the front.

• Smarter management of occupancy periods (living area during the day, night area in the evening).

• Reduction of typical temperature differences between floors or between the front and back of the building.

• Flexibility of evolution : the possibility of switching to a configuration of up to 4 zones opens up options for an added room, an office, or a bedroom in the basement.

We see this benefit particularly in:

• the cottages and split-level homes in Laval (Fabreville, Sainte-Dorothée) where the floors do not have the same thermal inertia,

• The plexes of Montreal (Rosemont, Ahuntsic, Villeray) where sunlight, shared walls, and insulation create very different behaviors,

• houses in Longueuil , Boucherville and surrounding areas where open spaces and large windows can cause “dominant” areas that are difficult to stabilize.

A useful reading of the features: what the numbers really mean

A product sheet often displays impressive specifications, but the important thing is to understand how these translate into real-world comfort. Here are the key features of this LG MULTI F TripleZone, explained as we would during an on-site visit.

Cooling capacity: 36,000 BTU

A 36,000 BTU air conditioning capacity in a multi-zone system primarily serves to ensure that several zones can be cooled without any single zone dominating the system. In practice, this prevents the following:

• the most exposed area (often the living room facing southwest) which monopolizes the effort,

• the rooms that remain “behind” during heat waves,

• the feeling that the setting needs to be lowered excessively to feel an effect throughout the house.

When the distribution of indoor units is well designed, this power becomes a very stable comfort lever, even in houses where heat accumulates on the second floor.

Heating: advertised capacity down to -16°C

In Quebec's climate, we like to be pragmatic. A heat pump does a remarkable job for much of the winter, but it's normal for a supplemental heating system to take over during more extreme periods. The goal with a system like this is to optimize comfort and energy consumption for as much of the cold season as possible, while maintaining simple and reliable operation.

What we often observe:

• A properly sized multi-zone system provides a very pleasant feeling of comfort on typical winter days.

• Temperature stability by zone reduces the temptation to constantly "play with the thermostat".

• The supplementary income becomes a safety net rather than a primary mode of transport.

R-32 refrigerant: a current choice

R-32 is a modern refrigerant, increasingly used in residential settings. From a practical standpoint, what matters to a customer is:

• The equipment is from a recent generation,

• The approach is consistent with market developments.

• The machine is designed for stable performance and long-term compatibility.

WiFi included: useful if used wisely.

WiFi isn't just a gadget. For homeowners with routines, it's a real tool:

• adjust a night zone without getting up,

• stabilize a temperature before returning home,

• avoid leaving an "unnecessary" area operating at full capacity,

• to harmonize habits between occupants of the same dwelling.

Our advice: the best use of WiFi is stability . Program and make small adjustments, rather than making abrupt changes several times a day.

Outdoor noise level: 54 dB(A)

Noise is often underestimated… until the first summer on the patio. A value of 54 dB(A) is good, but the real difference depends mainly on the installation:

• location (avoid corners that amplify the echo),

• clearance (to limit air recirculation),

• support (wall-mounted vs. floor-mounted base)

• vibration management (pads, anchors, leveling),

• distance from windows and rooms.

In Montreal and in several areas of the South Shore , where land is closer, this aspect becomes a critical point of satisfaction.

Electrical: 220V, MCA 19A, MOP 25A

This data is not insignificant. It guides compliance and reliability:

• good circuit breaker,

• good cable gauge,

• adequate protection

• clean and safe installation.

A successful multi-zone installation is also an electrical installation designed to last.

Guarantee: 10-10-0 and the importance of a protection strategy

The advertised warranty (compressor and parts) is reassuring, but the real question is: "How can we maintain peace of mind for several years?" With a multi-zone approach, some customers opt for additional protection, especially if the house is rented or if the owner wants maximum predictability.

How we design a TripleZone: the AirGreen method, step by step

Multi-zone systems are one of the segments where the quality of the result depends more on the design and execution than on the brand itself. As we often say: an excellent machine poorly integrated can produce mediocre results. A good machine well integrated can produce outstanding results.

1) Define 3 “functional” zones, not just 3 rooms

A zone is a volume that behaves in a similar way. We analyze:

• open volumes,

• stairs and heat stratification,

• the exposure (south, west, shaded),

• occupational habits,

• internal sources (kitchen, appliances, teleworking),

• air permeability (old window frames, doors, etc.).

A common real-life example : in Montreal (Ahuntsic) , a client wanted only units in the bedrooms because “the living room is already fine.” After analysis, it turned out to be the opposite: the living room overheated considerably in the summer, affecting the entire apartment. By designing two living areas (living room/kitchen + upstairs) and a separate sleeping area, the comfort level became significantly more stable, and energy consumption normalized.

2) Choose indoor units based on the desired comfort level, not just on BTU rating.

Several indoor models can be used for this outdoor unit. The choice depends on:

• acceptable noise level (bedroom vs living room),

• the range of the air jet,

• the room layout,

• ease of drainage,

• the aesthetics and the flow of the pipes.

We want to emphasize one point: an overly powerful indoor unit in a small room can create a drafty feeling and less comfortable conditions, even if the BTU rating seems perfect on paper. The goal is discreet comfort, not an "aggressive" presence.

3) The key factor: piping, lengths, insulation and drainage

In multi-zone systems, there's no room for improvisation. The errors we most often correct during replays or diagnostics are:

• lines that are too long or poorly routed,

• damaged or incomplete insulation (condensation, losses),

• poorly configured drains (insufficient slope, backflow),

• unsealed penetrations (noise, air infiltration),

• uneven supports (vibration, mechanical fatigue).

At AirGreen, we prioritize a clean finish:

• neatly aligned caches,

• sturdy fixings

• respecting clearances,

• clean and watertight wall penetrations,

• Clear identification of circuits and wiring.

These are details that are not always visible in the final photo, but that are felt every day.

4) Commissioning: the moment when the difference is confirmed

A proper commissioning includes:

• compliant vacuum drawing

• leak tests,

• validation of communications,

• verification of modes and reactions,

• settings adapted to the zones

• explanation to the customer (simple, practical, without jargon).

We then provide simple usage rules, because many “problems” are actually control habits that disrupt inverter modulation:

• avoid frequent changes in setpoints,

• maintain a stable temperature in each zone.

• Use the modes correctly according to the season.

• Adjust the ventilation to avoid the sensation of direct airflow.

The most frequently asked questions from homeowners: concrete answers

“Are three zones too many?”

In many homes, three zones strike the perfect balance: a main living area, a sleeping area, and a cooler/warmer zone (basement, office, sunroom). Too much happens when zones are created haphazardly, or when rooms aren't truly separated (doors always open, large interconnected spaces).

“Can I heat only one zone in winter?”

Yes, but it needs to be done intelligently. Completely closing off an area for extended periods can create temperature and humidity fluctuations throughout the house. Our approach: maintain a reasonable temperature setting everywhere, then prioritize the occupied area.

“Why is the sensation different from one area to another?”

Because each zone has its own constraints: volume, insulation, windows, exposure. Multi-zone design doesn't eliminate the building's physics, but it provides tools to manage it. Sometimes, the best investment isn't an increase in BTUs, but:

• improved sealing,

• window treatment,

• an air circulation solution,

• a correction to the placement of the units.

“What mistakes are costly with multi-zone?”

Here are the mistakes we see most often:

1. Oversize a small area “just to be sure”.

2. Placing an indoor unit too close to a bed or sofa.

3. Neglecting drainage (slope and path).

4. Choose an outdoor location that amplifies the noise.

5. Wanting a radically different temperature in each zone (which increases the need for constant adjustments).

LogisVert subsidy and purchasing context: how we integrate it into the decision

An announced subsidy can help make a multi-zone setup more accessible. In practice, we primarily use it as leverage to:

• improve the quality of the design (instead of reducing the budget on installation),

• choose a more coherent configuration (better zones),

• leave room for a clean finish (supports, covers, proper drainage).

Our view: a grant is useful if it serves the overall quality of the project, not if it pushes for a quick decision.

Typical scenarios where this LG MULTI F TripleZone becomes an obvious choice

1) Duplex/Triplex in Montreal: Comfort per level

In several multi-unit buildings, the floors behave differently. A TripleZone allows for the processing of:

• a more exposed level

• a more shaded level,

• a quieter bedroom area.

Typical result: fewer complaints of “it’s too hot upstairs” and fewer constant thermostat adjustments.

2) Cottage in Laval: open rooms and central staircase

The stairs create a fireplace effect. With a cohesive multi-zone design:

• The living area remains stable.

• the night zone is not “pulled” by the needs of the lower level,

• The balance becomes more natural.

3) House on the South Shore: large windows + teleworking

A home office has become a real necessity. A dedicated office space allows you to:

• stable comfort throughout the day,

• precise control without disturbing other areas,

• a more logical consumption.
