LG DUALCOOL R32 Heat Pump | 18000 BTU | Laval

When an 18,000 BTU heat pump is actually “the right size” for Laval

In Laval , the demand for an 18,000 BTU wall-mounted heat pump is consistently high, and for good reason: this capacity often reflects the reality of residential properties here. But at AirGreen, we've learned one thing through our installations: it's not the "18,000" number that determines comfort, but rather the balance between capacity, the layout of the dwelling, air distribution, and the quality of the HVAC installation .

The LG DUALCOOL R32 in this configuration ( KNUAB181A indoor unit + KUSAB181A outdoor unit) is a modern solution focused on performance, control, and stability. It is distinguished in particular by:

• A cooling capacity of 18,000 BTU , very suitable for many houses and condos in Laval

• R-32 refrigerant, widely adopted in recent product ranges

• ENERGY STAR® and ENERGY STAR® Cold Climate Compliant

• The included Wi-Fi is appreciated for managing consumption and schedules.

• A design conceived to maintain real comfort, not just "power on paper".

Our goal here is not to repeat a technical specification sheet. Our goal is to translate this product into concrete benefits, with real-life situations encountered on construction sites, common mistakes to avoid, and a clear approach to what you get when the heat pump is well chosen and properly installed.

Who is this LG DUALCOOL R32 18,000 BTU suitable for in Laval?

In practice, we often recommend it in cases such as:

• Condo or townhouse with an open-concept living area (living room-kitchen) where the air conditioning needs to be efficient without being aggressive

• Bungalow: main floor that overheats in summer and consumes too much energy in winter due to the baseboard heaters

• Duplex/triplex: one floor to optimize, with a central hallway and side rooms

• Home office: requires stable comfort and a reasonable noise level

• Homeowners who want to reduce the use of electric baseboard heaters without turning their house into a construction site

Where we are cautious: in highly compartmentalized homes (closed doors, isolated rooms), or large multi-level properties. In these cases, even the best heat pump in the world won't correct poor air circulation. We then adapt the solution (location, orientation, sometimes multi-zone or hybrid strategy).

Understanding R-32 without “marketing jargon”

The R-32 is not a minor detail. It's a technological choice. For the homeowner, what this means in practical terms is:

• A system designed according to recent standards

• Strict installation procedures (vacuum sealing, testing, line cleanliness, leak-proofing)

• A performance logic that relies as much on the machine as on the execution

In short: the R-32 standard rewards installations done with precision and penalizes shortcuts. At AirGreen, this is exactly where we come in: we work with a consistent method because it's the only way to ensure a heat pump remains efficient and quiet for years.

The numbers that really matter on a daily basis

We can read charts, but here are the points that have a direct impact on everyday life:

1) Sound comfort
A wall-mounted heat pump can be technically "silent," but it can become irritating if poorly positioned. In a bedroom, for example, the goal is an installation that allows for the use of lower speeds without sacrificing air distribution. This is where the location and direction of the air outlet make all the difference.

2) Air diffusion
In Laval , many homes have an open-concept layout with a hallway leading to the bedrooms. If the unit is placed too close to a corner or facing a wall, the air will circulate. Conversely, intelligent placement allows the air conditioner to circulate and reduce temperature differences between areas.

3) Stability, not just power
Comfort isn't a blast of cold air for 10 minutes. It's a stable temperature, without fluctuations. A properly sized and installed heat pump maintains this stability effortlessly, and that's precisely what you feel... and what you see on your energy bill.

4) Wi-Fi control
Wi-Fi is useful when it serves a simple purpose: consistent schedules, reasonable adjustments, and monitoring during periods of extreme cold. We often see landlords save money simply by stopping the constant fluctuation in deposits.

LogisVert subsidy: how we are integrating it intelligently

On your product page, the Provincial Subsidy (LogisVert): $1596 is an important element. In practice, what creates problems is not the subsidy itself, but the lack of planning:

• Model chosen too quickly, then installation done without checking overall consistency

• Incomplete documentation

• Unrealistic expectations about what a single wall-mounted head unit can do in a highly compartmentalized house

At AirGreen, our approach is simple: we start with the home (layout, habits, hot/cold zones), then we validate the device and the documentation. This avoids unpleasant surprises and results in a clean, structured, and defensible project.

Guarantee and peace of mind: understanding the “10-10-0” without confusion

The warranty (compressor/parts/labor) presented as 10-10-0 must be properly understood. Many customers automatically assume that “everything is covered for 10 years.” In reality, labor coverage often depends on the chosen plan (extended warranty, program, conditions). That's precisely why we clarify these points before installation: you know what to expect, and you can make an informed decision.

AirGreen case study in Laval: comfort is not determined by a single specification line

In one of our typical projects in Laval , the client had a renovated bungalow with a large living room and kitchen on the ground floor and bedrooms on the same level. The old wall-mounted air conditioner did produce some cooling, but the living room was freezing cold while the hallway remained warm, and the bedrooms barely benefited from the air conditioning.

The customer wanted an 18,000 BTU heat pump and insisted on installing it above a door, "because it's discreet." It's the kind of detail that seems logical... but can ruin performance.

Our approach on the ground:

• We observed the airflow (where air can circulate and where it gets blocked)

• We chose a wall that provides a natural view towards the open area AND part of the corridor

• We planned the piping and drainage to avoid problematic slopes.

• We discussed habits: nighttime temperature, schedules, areas used

After installation:

• The living room stopped getting too cold in air conditioning mode

• The corridor has begun to stabilize (therefore better “transmission” of comfort to the rooms)

• The customer noticed a much quieter noise in the evening, because the machine no longer needed to work as hard.

The lesson: in 80% of cases, it is not “the brand” that makes the success, it is the intelligence of the implantation and the rigor of the installation.

The common mistakes we correct (and which are costly in the long run)

Here are the pitfalls we regularly see during service calls or repairs after a botched installation:

1) Installing the indoor unit for aesthetic reasons, instead of placing it to circulate air
A wall-mounted head that is too close to a corner, or blowing towards an obstacle, loses a great deal of effectiveness.

2) Neglecting water management (drainage)
An incorrectly calculated slope can cause uneven drainage, dripping, or odors. It's a technical detail, but it's a very real problem.

3) Underestimating the importance of line insulation
Poorly insulated piping can generate condensation and performance losses, especially in summer humidity.

4) Choose a capacity “at random”
Too small: the machine struggles and does not achieve peak comfort.
Too big: less optimal cycles, more aggressive air sensation, possible discomfort.
The right size is the one that corresponds to the building and its use.

5) Forgetting the interview
Even a high-end heat pump loses performance if the filters and indoor heat exchanger become clogged. HVAC maintenance isn't an extra; it's the logical continuation of your investment.

Practical usage tips to maximize efficiency in Laval

Here's what we most often recommend to homeowners, because these are simple actions that yield real results:

• For heating: prioritize a stable temperature setting (avoid sudden increases and decreases).

• For air conditioning: aim for a realistic temperature and let the unit run regularly

• At night: use a quieter mode rather than switching it off completely (depending on your habits).

• Filter cleaning: adapted to the lifestyle (pets, work, proximity to road)

• Keep the grilles clear: curtains, furniture, and shelves can disrupt the diffusion.

These are details, but accumulated over a full season, they change the bill and the comfort.

HVAC installation: what we do systematically at AirGreen

When we install an LG DUALCOOL R32 in Laval , here is our standard approach:

1) Validation of positioning
We are looking for the area where air can travel most naturally, taking into account obstacles, stairs, and areas at risk of overheating.

2) Clean and logical piping route
A well-planned route means less mechanical stress, a cleaner finish, and better long-term reliability.

3) Secure drainage
We favour a solution that minimizes the risk of water damage, even during peak humidity and long periods of air conditioning.

4) Rigorous commissioning
It's not just about "turning it on". It's about verifying that the device works as intended, that the settings are consistent, and that the customer understands how to use it effectively.

5) Clear explanation to the owner
We prefer a simple and practical explanation rather than a theoretical course: how to adjust, how to maintain, what to monitor, and when to call.

HVAC Maintenance: The Short Checklist to Avoid Problems

To maintain performance over the years, we recommend:

• Filter cleaning according to usage (more frequent if pets or dust are present)

• Annual or periodic inspection depending on the environment and use

• Checking the drain flow

• Professional cleaning when necessary (especially if there is a drop in airflow, odors, or reduced performance)

The goal is not to "sell a service call." The goal is to avoid unnecessary service calls and maintain a system that performs as well as it did on day one.
