LG ARTCOOL PRESTIGE R32 Wall-Mounted Heat Pump | 24,000 BTU (-25°C)

When a 24,000 BTU heater becomes a true "comfort system" in a Montreal home

In Montreal , Laval , Longueuil , on the North Shore and the South Shore , a 24,000 BTU unit isn't chosen "to be more powerful." It's chosen to be just right : enough capacity to stabilize comfort, enough efficiency to limit consumption, and enough headroom to get through our cold snaps without turning the house into a construction site of thermometers.

The LG ARTCOOL PRESTIGE R32 24,000 BTU (-25°C) (indoor unit KNSAL241A / outdoor unit KUSAL241A ) is one of the few wall-mounted heat pumps that combines three very real expectations of homeowners here: true heating capacity in cold weather, stable cooling during heat waves, and a modern user experience (control, comfort, noise, maintenance). At AirGreen, we install it in a wide variety of settings: urban condos, duplexes, bungalows, open-concept homes, and even properties where the goal is to reduce the use of electric baseboard heaters without complicating daily life.

The numbers that matter (and what they mean on the ground)

Technical specifications are useful… provided they translate into real-world impacts. For this 24,000 BTU wall-mounted heat pump , the factors that directly influence comfort and seasonal performance are:

• Nominal cooling capacity: 24,000 BTU (with a range that allows modulation according to actual needs).

• The advertised heating capacity is down to -25°C , which corresponds to our winter reality (and not just to “mid-season” use).

• R-32 refrigerant , a choice that is part of the evolution of modern refrigerants, with a logic of efficiency and environmental compliance.

• Inverter (variable speed) : instead of alternating “full speed / off”, the machine adjusts continuously, which improves comfort stability, reduces perceived noise and, often, decreases consumption during long periods at partial load.

What we observe most often: when a wall-mounted heat pump in this range is properly sized, it doesn't "just heat". It stabilizes the entire space, avoids temperature fluctuations, and provides that feeling of consistent comfort that makes you forget the system is even there… which is exactly the goal.

ARTCOOL: the design is visible, but the logic is also technical

The choice of ARTCOOL often stems from a simple constraint: the indoor unit isn't hidden away in a mechanical room. In a condo or open-concept living room, it blends seamlessly into the decor. But beyond aesthetics, this series is appreciated for its "complete product" approach: control, smart modes, air management, and features designed for everyday life.

This configuration typically includes:

• Wi-Fi included , convenient for adjusting settings remotely, managing schedules, or quickly checking operating status.

• Automatic control of the shutters (vertical and horizontal) to better distribute the air in the room and limit direct airflow.

• Comfort modes (sleep, timer, final settings) that help reduce irritants: too cold at night, too hot when waking up, or variations when sunlight changes.

• Diagnostic assistance functions , useful for speeding up certain checks and reducing intervention time during a service call.

In our AirGreen practice, the benefit is twofold: the customer gets simpler operation, and we can structure HVAC maintenance more efficiently, with clear control points.

For whom is this 24,000 BTU unit really relevant?

A 24,000 BTU unit is often ideal in the following cases (to be confirmed on site, as each building is unique):

• Common areas of a house (living room/kitchen/dining room) where you want the heat pump to do most of the work.

• Condo or main floor with a large air volume and significant solar exposure.

• Plex where the objective is to stabilize the main unit, while keeping the rooms closed with minimal supplementary heating.

• Renovated properties : when insulation and sealing have been improved, a well-chosen heat pump gives impressive results on the bill.

Conversely, when the space is highly compartmentalized (small, enclosed rooms, hallways, frequently closed doors), we must be more cautious: a wall-mounted unit heats and cools the area it "sees" very well, but it doesn't replace a centralized air distribution system. This is where our on-site assessment becomes crucial: sometimes a multi-zone system, sometimes a different strategy, sometimes a different location that makes all the difference.

AirGreen Case Studies: 3 Typical Scenarios in Montreal, Laval and the South Shore

Scenario 1 – Condo in Griffintown (Montreal): comfort and silence in a glass-enclosed space
Here, the challenge wasn't the size, but the sunlight and sound reverberation. In a glass-walled condo, heat builds up quickly, and the air conditioning needs to react without creating a draft. We chose a location that avoids blowing directly onto the workspace, then adjusted the settings to promote a more gradual distribution. The result: more consistent comfort, fewer fluctuations, and reduced perceived noise, especially in the evening.

Scenario 2 – Bungalow in Vimont (Laval): reducing baseboards without complicating the routine
The client primarily used electric baseboard heaters. The goal wasn't "zero baseboards," but "minimizing their use." We sized the system so the heat pump would cover the open area and passageways, then explained a simple strategy: a stable heating setpoint, doors open at certain times, and slight adjustments during periods of extreme cold. This type of project works very well because the heat pump becomes the primary source of heating, with a backup system that only activates when needed.

Scenario 3 – Cottage in Boucherville (South Shore): Winter performance and controlled de-icing
The client had a legitimate concern: “Will it still work in January?” Part of the answer lies in the product, but another part lies in the installation: clearance around the outdoor unit, drainage management, a location that minimizes snow accumulation, and rigorous commissioning. In this type of project, nothing is left to chance: we consider ice storms, thaws, and how water drains. The desired result isn't just a warm house, it's a warm house without any surprises .

AirGreen Installation: What we check to ensure you get the advertised performance in your home

A successful HVAC installation is a series of simple, but non-negotiable decisions. On the LG ARTCOOL PRESTIGE R32 24,000 BTU , here's what we systematically focus on, because these details make the difference between "it works" and "it's pleasant every day."

1) Sizing: avoiding two costly mistakes

Mistake #1: Oversizing “just to be sure”
Too big = short cycles, less well controlled humidity in summer, less stable comfort, and sometimes a recurring “hot/cold” sensation.

Mistake #2: Undersizing “to save money”
Too small = device at full load too often, more frequent electrical top-ups, and performance that plateaus during cold snaps.

At AirGreen, we design based on the actual architecture: volumes, insulation, windows, orientation, air infiltration, and lifestyle (teleworking, constant presence, closed rooms). In Montreal and on the North Shore , two houses that appear "similar" on paper can perform very differently depending on wind exposure, the condition of the building envelope, and the floor configuration.

2) Indoor unit location: comfort is not about “blowing hard”

With a wall-mounted fan, the goal is to mix the air without creating uncomfortable zones. A good location:

• limits direct breathing towards a sofa, bed or dining table

• promotes a sweep of the common area

• avoids obstacles that break the flow (falls, beams, tall cabinets)

• maintains realistic access for maintenance (filters, cleaning, inspection)

In some cases, a few tens of centimeters make all the difference. This is often seen in condos and open-plan rooms: the device may be excellent, but a poor diffusion angle gives the impression that it is "forcing" itself when it simply lacks a better trajectory.

3) Piping and finishing: reducing losses and simplifying HVAC maintenance

Piping is not just an aesthetic detail. A well-designed refrigeration line:

• reduces the risk of vibration and noise

• protects the installation against wear and tear (friction, UV rays, impacts)

• facilitates future diagnosis if an interview is required

• improves the overall quality of the installation (and therefore customer satisfaction)

We pay particular attention to the slope, protection, wall penetrations, sealing, and pipe coverings. A beautiful finish is not a luxury: it is often an indicator of methodical work.

4) Vacuum, sealing, commissioning: the key elements that determine the reputation of an installation

This is where many "mediocre" projects are created. A serious commissioning involves:

• a well-executed and controlled vacuum draw

• a leak test

• tested drainage (especially if the slope is long or if the unit is above a finite space)

• validation of the modes (heating/cooling) and general behavior

These are steps that don't attract attention in a photo, but determine longevity and yield.

5) Electricity: compliance, safety, reliability

This machine operates on 220V , and the connection must comply with protection, amperage, and wiring regulations. We verify the panel capacity, circuit quality, and appropriate protection, and we clearly document the installation.
In Laval and Longueuil , we often encounter homes where electrical additions have been made over the years; our role is to ensure that the heat pump is connected correctly, without compromise.

6) Outdoor unit: snow, ice, surrounding area and clearance

Winter is not a “normal season” for a heat pump in Quebec. You need to consider:

• the accumulation of snow

• water runoff during defrosting

• the clearance around the unit to allow for proper breathing

• vibrations and sound transmission

In urban Montreal , location can also be dictated by neighborhood constraints: distance from a window, access, condominium rules. This is part of AirGreen's work: finding a solution that respects these constraints without sacrificing performance.

7) Noise: what we do to make the machine unobtrusive

The perceived noise depends as much on the installation as on the device. To limit vibrations and disturbances:

• anti-vibration mounts adapted to the surface type

• solid anchoring (avoid the “drum” effect)

• Sufficient clearance to avoid turbulence

• pipe routing designed to avoid vibration within the walls

In a condo, good noise management also means good neighborly relations. We treat this aspect as an installation criterion, not as an option.

8) Wi-Fi and everyday use: the goal is simplicity

The included Wi-Fi is only useful if the customer is comfortable using it. That's why we're taking the time to explain the simple reasoning:

• Stable heating setpoint (avoid extreme variations)

• realistic schedules (not aggressive “off/on”)

• use of comfort modes according to habits

• Intelligent management during absences (no need to turn everything off)

A poorly managed heat pump can become costly, even if it is efficient. A well-managed heat pump provides measurable savings and more consistent comfort.

9) HVAC Maintenance: What we recommend to maintain efficiency

Even with self-cleaning functions, maintenance remains a major driver of performance. Our recommendation, tailored to the realities of homes in Montreal , Laval , and the South Shore :

• Filters : regular inspection, cleaning depending on dust levels and the presence of animals

• Drainage : periodic checks to prevent odors, overflows, or dampness

• External battery : gentle cleaning, leaf clearing, obstacle control

• Seasonal inspection : verify stability, listen for abnormal noises, check diffusion quality

Proper maintenance prolongs lifespan, maintains efficiency, and reduces the risk of service calls in the middle of winter.
