LG DUALCOOL R32 Heat Pump | 30000 BTU | Laval

A 30,000 BTU R-32 heater designed for our winters and our homes in Laval

In Laval, indoor comfort isn't simply a matter of "heating in winter" and "cooling in summer." Homes here have their own unique characteristics: open-concept layouts that amplify temperature fluctuations, stairwells that create stagnant areas, partially finished basements that remain cool even in July, and upper floors that become stifling as soon as humidity sets in. Additions built over the years, partial insulation upgrades, and multigenerational dwellings where heating and cooling needs vary from one area to another are also very common.

In this type of situation, a 30,000 BTU wall-mounted heat pump isn't inherently "too powerful." Rather, it becomes a stabilizing tool, capable of managing heat spikes and rapid drops, while finely modulating its output when the house doesn't need its full power. This is precisely the logic behind the LG DUALCOOL R32 30,000 BTU heat pump , a single-zone wall unit that emphasizes inverter precision, consistent comfort, and a user-friendly experience, especially when you want to avoid constantly adjusting the settings.

At AirGreen, we install this type of unit in Laval, always aiming for the same goal: consistent comfort, predictable performance, and an installation that remains quiet and reliable for years . And this result doesn't come from the machine alone: ​​it comes from the entire combination of product, configuration, location, and commissioning.

Why this format appeals so much to Laval: simple, effective, and very practical

The single-zone wall format is perfectly suited to many common situations:

• a complete ground floor (living room, kitchen, dining room) which lacks temperature control;

• a large dwelling where the central area influences everything else;

• a house where the upper floor is difficult to air-condition;

• a home workspace (office, workshop) that needs to remain comfortable without air conditioning the whole house.

And above all, it is a format that allows for a rapid transformation of comfort: once the installation is complete, customers immediately feel the difference in temperature stability, but also in the sensation of "less heavy" air, thanks to better managed dehumidification.

The key takeaway regarding performance: comfort lies in actual capacity and modulation

Capacity figures are important, but what really matters is the machine's ability to keep up with the pace of the home .

• Nominal cooling capacity: 30,000 BTU/h
  It is a capacity that covers larger areas and, above all, allows us to manage humid days where the air conditioning load comes not only from temperature, but also from humidity.

• Heating: significant performance in cold conditions
  The reality in Quebec isn't simply "Does it heat up to +5°C?". It's: "Does it maintain comfort when the outside temperature drops rapidly, when the wind picks up, when the house loses more heat?" A well-chosen and properly installed 30,000 BTU heater helps avoid temperature fluctuations that force occupants to constantly adjust the settings.

• Refrigerant gas: R-32
  R-32 represents a significant evolution in new installations. For the owner, this primarily translates into a machine aligned with current generations of equipment and a more modern approach to refrigeration.

• Wi-Fi included
  In real life, Wi-Fi is more than a gadget: many customers in Laval use it to adjust the temperature before returning home, control a rental property, or simply prevent the house from overheating during an absence.

A key point: “power” does not mean “overconsumption”.

A common concern is: “If I get 30,000 BTU, will I pay more?”
The answer depends on the sizing and how the machine modulates. In a well-designed installation, a heat pump of this range doesn't operate at full power its entire lifespan. It adjusts its capacity according to the actual demand. The result: improved comfort and consistent energy consumption.

What we want to avoid are systems that are too small and run constantly at full capacity, without making up for the difference, resulting in a less comfortable feeling of air and periods where the house "cannot" reach the desired level of comfort.

Technical details that really matter on a daily basis

In the field, we emphasize the details that influence the actual experience:

• 220V power supply
  A heat pump of this capacity requires a compliant electrical connection. In Laval, in many older homes, the electrical panel may need to be inspected beforehand. This isn't an obstacle, but it's something to consider before planning the installation.

• Circuit protection and sizing
  A properly sized circuit, with appropriate protection, prevents nuisance tripping and contributes to long-term reliability.

• Noise level: indoors and outdoors
  Indoors, this type of wall-mounted unit offers multiple speeds and a sleep mode to reduce perceived noise at night. Outdoors, placement becomes crucial: an outdoor unit may seem perfectly acceptable on paper, but if poorly positioned, it can amplify noise through resonance or reflection off certain surfaces (brick walls, fences, patios, etc.). Our role is to choose a location that minimizes these effects.

• Airflow and diffusion
  A 30,000 BTU unit also delivers significant airflow. Wall mounting must allow for efficient air distribution; otherwise, you might end up with a very comfortable living room, but a hallway or adjacent room that remains difficult to regulate. This is often where the “AirGreen” experience makes all the difference: we position the unit with actual airflow in mind, not just aesthetics.

AirGreen case study in Laval: duplex, stagnant heat and uneven air conditioning

We had a typical case in a duplex in Laval: a smaller heat pump was already in place, but the client never felt the temperature was consistent. In the summer, a bedroom at the back remained too hot; in the winter, the area near the stairs was comfortable, but the living room required constant adjustments.

What made the difference:

1. analysis of air movement : doors, corridors, dead zones;

2. choosing a “strategic” wall location : oriented to push air towards the affected area;

3. adjusting shutters and speeds according to actual usage (occupancy times, areas used in the evening);

4. reduction of variations through better-adapted modulation.

The client's feedback after a few weeks: the house seemed "more stable," not only in temperature but also in terms of air quality. Humid days were easier to bear, and the need to manually adjust the settings had almost disappeared.

This type of improvement is exactly what homeowners are looking for: comfort that becomes “normal”, without them even thinking about it.

Common mistakes to avoid (that end up requiring service calls)

With a 30,000 BTU wall-mounted unit, shortcuts will come at a price sooner or later. The most common mistakes are:

• Choose the location solely for convenience
  A “simple” wall for running pipes is not necessarily the wall that will provide effective diffusion.

• Underestimating the importance of refrigeration piping
  Poorly designed piping, too exposed or with complicated passages, increases the risks of vibrations, losses, or drainage problems.

• Poorly managed drainage
  The drainage system must be logical, with an appropriate slope, and with particular attention to the risks of frost.

• Approximate electricity
  A 220V installation must be compliant, correctly sized, and adequately protected.

• Commissioning too quickly
  Real performance and longevity are achieved during commissioning: testing, verification, precise adjustments.

AirGreen installation in Laval: method, transparency and measurable results

At AirGreen, we treat installation as a complete project. This is the most important point to understand: a high-end heat pump installed "correctly" may give average results; a well-installed heat pump, with a focus on comfort and optimization, gives superior results.

Our approach to a typical installation

• On-site assessment : we check the space, needs, location constraints, and electricity.

• Choice of indoor location : we aim for the best air distribution, not just the most discreet location.

• Choice of outdoor location : clearances, noise, service access, snow accumulation, drainage.

• Pipe routing planning : clean, logical, and sustainable.

• Commissioning and adjustments : to ensure the machine works stably and quietly.

What customers appreciate most (in real life)

• Practical functions : quick comfort modes, automatic restart after power failure, automated shutter management.

• Simple control : clear remote control, and control via Wi-Fi for those who want remote management.

• Stable comfort : fewer variations, fewer manual corrections, a more pleasant feeling of air.

Guarantee and realistic expectations

On a heat pump of this category, the warranty protects the equipment. But our experience is very simple: HVAC installation and maintenance determine the majority of what happens next.

To maintain consistent performance:

• Regular cleaning of the filters;

• drainage check;

• maintaining a free space around the outdoor unit;

• periodic inspection to ensure that everything remains stable and watertight.

We always remind you of the same thing: a well-maintained heat pump remains quieter, more efficient, and more reliable.

An important point in Laval: noise, neighbors and outdoor positioning

In Laval, many properties have closely spaced backyards, fences, patios, or walls that can amplify noise through reflection. That's why we pay particular attention to:

• to the orientation of the outdoor unit;

• to anti-vibration mounts;

• to allow clearance for airflow;

• to the distance between rooms when possible.

It's the details that transform the experience: a well-placed outdoor unit becomes a discreet element; poorly placed, it becomes an irritant.
