A High-Performance Central HVAC Solution Perfectly Suited to Greater Montreal's Realities

At AirGreen, we regularly install central systems designed to meet Quebec's demanding winters and humid summers. The 2-ton (24000 BTU) LG multi-position air handler, combined with the KUSXB241A central heat pump, stands out as a reliable, flexible, and optimized solution for residences and small buildings in Greater Montreal, Laval, Longueuil, North Shore, and South Shore.

This model, identified by the number KNSLB241A, is distinguished by its compatibility with ENERGY STAR and ENERGY STAR Cold Climate requirements, its use of R-32 refrigerant, and its consistent performance even in harsh winter conditions.


Real-World Performance: What We Observe During Our Installations

Cooling Capacity and Energy Efficiency

During our installations in Montreal and Laval, this model demonstrates a stable cooling capacity of up to 30,000 BTU at peak, with a nominal range of 24,000 BTU.

  • SEER2: 17.50
  • EER2: 12.00
  • Airflow up to 800 CFM (high mode)

These values ensure effective cooling even during prolonged heatwaves, while maintaining controlled energy consumption.

Heating in Cold Climates: A Critical Point in Quebec

In our projects on the South Shore and Montérégie, heating performance is a decisive factor. This system offers:

  • Nominal capacity up to 30,000 BTU
  • 25,000 BTU at 17°C outside
  • 22,000 BTU at 5°C
  • 21,000 BTU at -4°C

In practice, this means the system continues to provide stable heat even when temperatures drop below -15°C, which corresponds to local winter realities.


Multi-position Configuration: A Concrete Advantage in Installation

Maximum Adaptability

The multi-position air handler allows for several configurations:

  • Vertical installation (closet or basement)
  • Horizontal installation (ceiling or confined space)
  • Downflow conversion with appropriate kit

In several projects completed in Longueuil and Boucherville, this flexibility allowed us to optimize space without modifying the building's existing structure.

AirGreen Concrete Example

In a multi-story residence on the North Shore, the lack of basement space made a standard installation impossible. Thanks to the LG unit's horizontal configuration, we:

  • Avoided major modification work
  • Reduced the overall project cost
  • Maintained uniform air distribution throughout the house

Essential Technical Data to Know

Main Features

  • Voltage: 208-230V / 60Hz
  • MCA: 16A
  • MOP: 25A
  • Refrigerant: R-32 (more ecological than R-410A)
  • Refrigerant Charge: 67 oz
  • Piping: 3/8 – 5/8

Sound Level

  • Indoor: 29 to 36 dB(A)
  • Outdoor: 52 dB(A)

These levels are particularly appreciated in urban installations in Montreal, where acoustic comfort is an important criterion.

Dehumidification

  • Capacity: 4.23 pints/hour

An often underestimated point, but crucial for Quebec's humid summers.


HVAC Installation: Mistakes to Avoid (AirGreen's Experience)

Incorrect System Sizing

We regularly observe improperly sized installations by other contractors. With a 2-ton (24000 BTU) system:

  • Too small → constant thermal discomfort
  • Too large → short cycles, premature wear

At AirGreen, we always perform a precise calculation based on:

  • Actual surface area
  • Insulation
  • Sun exposure
  • Number of occupants

Poor Airflow Management

The LG unit allows for airflow up to 800 CFM, but the ducts must be adapted. Poor duct design can:

  • Reduce overall efficiency
  • Increase noise
  • Create cold or hot spots

Subsidies and Savings: An Immediate Advantage

This model is eligible for the LogisVert (Hydro-Québec) program with a subsidy of up to $2,100.

In several recent projects in Laval and Longueuil, our clients significantly reduced their initial investment thanks to this aid.

Real-Life Example

A client in Saint-Hubert replaced an old electric system:

  • Consumption reduced by almost 35%
  • Improved comfort in winter
  • Accelerated return on investment thanks to the subsidy

  • Regular filter replacement (16 x 20 x 1)

At AirGreen, we offer tailored HVAC maintenance plans to prevent any loss of performance.


AirGreen Customer Feedback

A customer in Ahuntsic (Montreal) contacted us after a problematic installation performed by another supplier. After replacement with this LG model:

  • Uniform temperature throughout the house
  • Reduced indoor noise
  • Significant improvement in winter comfort

This type of situation is frequent and confirms the importance of an installation carried out by experienced professionals.
