LG DUALCOOL R32 Heat Pump | 36000 BTU | Laval

When 36,000 BTUs make a real difference in Laval

In Laval, we very often encounter homeowners who already have a "working system," but it never achieves the expected comfort. In the summer, the air conditioning seems adequate near the wall unit, but the coolness doesn't reach the more distant rooms. In the winter, the heating is present, but the sensation isn't uniform: one area is too hot, another remains cool, one floor doesn't keep up, or the basement becomes a veritable "cold trap." In these situations, a 36,000 BTU wall-mounted heat pump isn't simply a matter of power; it's a concrete solution to problems of air volume , circulation , and thermal balance.

The LG DUALCOOL R-32 36,000 BTU (indoor unit KNSAP361A , outdoor unit KUSAP361A , AHRI 215735332 ) is specifically designed to meet this need: a unit capable of handling higher loads while maintaining the flexibility of an inverter system (meaning it can modulate rather than operate in an "on/off" mode). In practice, this modulation truly transforms the experience: fewer fluctuations, fewer harsh cycles, and a more stable feeling of comfort, especially in open-plan homes.

What we're taking away from Laval (and why)

When we evaluate a property in Laval, we don't just analyze the land area. We analyze the reality, the one that influences performance every day:

• The actual volume to be treated : cathedral ceiling, mezzanine, open area, central staircase, partially open basement.

• The geometry of the rooms : a long corridor, rooms in a row, doors permanently closed.

• Orientation : a west-facing facade can turn the end of the day into an air conditioning challenge.

• The building envelope : insulation, windows, thermal bridges, air leaks, addition of extensions.

• Air circulation : where air “can travel”, and where it cannot.

• Lifestyle habits : teleworking, bedrooms upstairs, kitchen used intensively, presence of animals (dust/hair), etc.

With a capacity of 36,000 BTU , the goal isn't to "make it too cold" or "too hot." The goal is to have enough reserve so the machine can operate comfortably , without being pushed to its limits, and without losing its stability during extreme conditions.

Useful key data (clear, practical, and above all relevant)

Here are the elements we consider truly important for a successful HVAC installation :

• Cooling capacity : 36,000 BTU (rated power 36,000 BTU).

• Gas (refrigerant) : R-32 (newer, widely adopted in new generations).

• WiFi : included , therefore remote control and finer daily management.

• Voltage : 220V (power supply must be provided correctly).

• MCA / MOP : 23 A / 30 A (minimum amperage and maximum protection: essential for a compliant electrical installation).

• Piping : 3/8 – 5/8 (sizing is critical for reliability).

• Noise level : a point of comfort and neighborliness to be respected, especially in densely populated residential areas.

• Warranty : 10-10-0 years (compressor – parts – labor), with the possibility of an additional warranty depending on the conditions.

And importantly: on your page, the Provincial Subsidy (LogisVert) is listed as $0 on the date mentioned. In reality, the best practice is always to verify the programs at the time of the quote, because the criteria and lists of eligible models can change.

Installation in Laval: what makes the difference between “it works” and “it’s perfect”

A heat pump can look excellent on paper but be disappointing in practice if the installation is done "as usual." With an LG DUALCOOL 36,000 BTU , the quality of the installation becomes even more apparent, because the unit has the capacity to move a lot of air and operate at a sustained pace.

We summarize our approach in a simple idea: the machine should not compensate for installation errors . It should operate under its best conditions.

1) The location of the mural: the air must circulate efficiently

In a typical Laval house, we often see:

• a large main space (living room/kitchen/dining room),

• a staircase that creates a natural "draft",

• more isolated rooms,

• sometimes a rear extension.

The classic mistake is to place the wall unit where "it looks good", rather than where the air can actually be distributed.

What we are aiming for:

• A wall that overlooks the main living area , where we spend most of our time.

• A height that allows for good air circulation, without directly "pulling" on the occupants.

• An orientation that limits the “cold jet” effect in a specific area (e.g., directly onto a sofa).

• A position that allows for proper management of piping , drainage , and accessibility for maintenance.

2) The outdoor unit: stability, clearances, and noise management

The outdoor unit is not simply an “outdoor box”. It is the foundation of the system: vibrations, clearances, snow accumulation, air exhaust, service access.

In Laval, we pay attention to:

• The distance from the bedroom windows.

• The proximity of a patio or relaxation area (noise and airflow).

• Positioning to avoid a snow corridor or a place where ice accumulates.

• A solid (and well-designed) base to reduce vibrations and preserve durability.

3) Electricity: the detail that prevents “mystery” breakdowns

The majority of "unexplained" problems we see on existing installations stem from one source: electrical . Too often, we plug it in and think it'll work, and later we experience tripping, errors, or unstable performance.

With a machine like this, we emphasize:

• The correct cable gauge.

• Correct protection (circuit breaker sized according to the required parameters).

• A compliant grounding system.

• A clean and safe installation, without improvisation.

4) The piping: this is where performance is achieved

An R-32 heat pump must be installed with rigor: quality of connections, cleanliness of lines, testing, evacuation of air and moisture from the circuit.

What we systematically treat:

• Respecting the pipe diameter.

• Protection against UV rays and wear (especially on exposed areas).

• Reducing vibrations transmitted to the walls.

• A logical and accessible route (one day, an interview or intervention may be necessary).

• Length management: when an installation requires a longer passage (which happens in several houses), we respect the technical logic of the device to maintain performance.

5) Drainage: a small detail, a big impact

In Montreal and Laval, summer humidity is intense. A wall-mounted air conditioner extracts a lot of moisture from the air: that means water , plain and simple.

Classic problems:

• Drain without sufficient slope.

• Poorly protected drain outlet.

• Condensation that appears on a poorly insulated cold spot.

Result: drips, stains, odors, or persistent dampness.

This is exactly the kind of situation that can be avoided with a clean installation from the start, and a real verification in operation.

Features and use: making performance "livable" on a daily basis

A good heat pump is not just a device that "pushes air". It must integrate into the routine without creating constraints.

WiFi included: useful when used intelligently.

WiFi is particularly useful for:

• Adjust the comfort level before returning home.

• Slightly reduce the air conditioning during an absence, without turning it off completely.

• Maintaining a stable temperature in a sensitive area (home office, very sunny room).

In reality, the best results often come from a simple adjustment: avoid extremes, prioritize stability, let the inverter do the work.

Airflow management: avoid "the jet" and distribute

On a powerful wall-mounted unit, the orientation of the shutters is crucial. Our advice, based on field experience:

• Adjust the flow so that the air mixes with the volume, instead of hitting an area directly.

• Use appropriate speeds: too low = air doesn't circulate, too high = feeling of a draft.

• Adjust the settings according to the use of the rooms (day vs night).

Indoor noise: the difference between thermal comfort and actual comfort

Internal noise is often underestimated. Even if a machine is efficient, if it becomes "present" continuously, it becomes tiring.

That's why we:

• Let's avoid placing them too close to a bedroom.

• Let's optimize the distribution to reduce the need for high speeds.

• and let's adjust the system to aim for stable comfort, rather than a fast and noisy "attack".

Concrete scenarios in Laval (and what we are actually doing)

Case 1 — Open area + central staircase: “it cools down, but not everywhere”

Property: large ground floor, open kitchen, staircase to the upper floor.
Problem: the living room is cool, but the upstairs bedrooms remain warm.

AirGreen Solution:

• The wall unit's position is optimized to direct part of the flow towards the staircase.

• Adjusting the flaps and speeds to create a constant airflow.

• Programming adjustments (stable temperatures rather than variations).

Result: fewer differences between levels, more uniform comfort.

Case 2 — Renovated house: “We replaced the windows, but it's still very hot in the summer”

Property: renovations, new windows, but large glazed area.
Problem: significant solar gain, especially at the end of the day.

AirGreen Solution:

• Actual assessment of solar loads.

• Installation designed to handle peak loads without being at its limit.

• Settings for stable operation during hot hours.

Result: the machine does not "chase" the temperature, it maintains it.

Case 3 — Neighborhood-sensitive client: “I want comfort without disturbing anyone”

Property: tight residential area.
Problem: Concern about outside noise.

AirGreen Solution:

• Strategic positioning of the external unit.

• Base and fixing properly insulated.

• Optimizing the piping route to reduce vibrations.

The result: comfort and tranquility, without compromise.

Mistakes to avoid (the costly ones... that can be easily avoided)

• Choosing capacity based solely on surface area : volume, orientation, and air circulation are just as important.

• Underestimating the importance of electricity : inadequate protection creates breakdowns and instabilities.

• Neglecting the quality of the fittings : a "quick and dirty" installation becomes a problem later on.

• Completely switching off the machine instead of modulating : the inverter works better for stability.

• Forget about maintenance : filters, cleanliness, regular checks = performance and durability.
