LG Multi-position Blower Cabinet | 1 Ton - 12000 BTU

A Compact and Efficient HVAC Solution Perfectly Suited to Greater Montreal's Realities

In the field of HVAC in Montreal, Laval, Longueuil, the North Shore, and the South Shore, choosing a reliable, quiet, and efficient central system makes all the difference, especially when optimizing comfort in a confined space. The LG KNSLB121A multi-position air handler, designed to work with the KUSXB121A central heat pump, represents a particularly effective technical solution for residential and multi-dwelling properties.

At AirGreen, we regularly install this type of equipment in various contexts — condos, single-family homes, duplexes, and renovation projects — and we observe consistent results: energy efficiency, thermal stability, and quiet operation.

Performance and Energy Efficiency: Numbers That Truly Matter

Heating and Cooling Capacities Adapted to the Quebec Climate

This 1-ton (12,000 BTU) model offers well-balanced performance for small to medium-sized spaces:

• Cooling: 12,000 BTU
• Effective heating down to -16°C
• Capacity at -8°C: 9,500 BTU
• Capacity at -15°C: 10,500 BTU

These values are particularly relevant for Quebec winters, where heating stability becomes critical. Unlike many entry-level systems, this unit maintains useful capacity even in cold conditions.

Advanced Energy Performance

• SEER2: 16.20
• EER2: 12.20
• HSPF2: 9.50
• COP at -8°C: 11.853

This specifically means:

• Optimized electricity consumption
• A significant reduction in energy costs
• Eligibility for programs like LogisVert (subsidy of $1140)

At AirGreen, we have observed an average decrease of 20 to 30% in energy costs after replacing old electric systems with this type of LG central heat pump.

Multi-Position Installation: Maximum Flexibility for Complex Projects

Configuration Adapted to All Types of Homes

The LG multi-position air handler allows for installation:

• Vertically (upflow or downflow)
• Horizontally (ceiling or false ceiling)

This flexibility is essential in several projects in Montreal, notably:

• Basements with low ceilings
• Condos with limited technical space
• Renovations where existing ducts must be retained

Real-Life AirGreen Installation Example

In Boucherville (South Shore), we recently installed this model in a condo where mechanical space was extremely limited. Thanks to the horizontal configuration and compact size (18 x 21.41 x 49.41 inches), we were able to integrate the system without major modification to the existing structure.

Result:

• Quick installation
• No aesthetic compromise
• Optimal performance from commissioning

Acoustic Comfort and Indoor Air Quality

Quiet Operation

• Indoor sound level: 28 to 34 dB(A)
• Outdoor sound level: 52 dB(A)

This sound level is particularly appreciated in residential environments where acoustic comfort is a priority.

In several projects in Laval and Longueuil, our clients reported a significant improvement compared to their old noisy systems.

Airflow and Dehumidification

• Airflow: up to 500 CFM
• Dehumidification: 1.27 pints/hour

This ensures:

• Uniform air circulation
• Reduced humidity in summer
• Improved overall comfort

Essential Technical Specifications to Know

Electrical Data and Installation

• Voltage: 208-230V / 60Hz
• MCA: 13.4 A
• MOP: 15 A

Piping and Configuration

• Liquid line: 1/4
• Vapor line: 3/8
• Max length: 65.6 feet
• Max elevation: 49.2 feet

These characteristics allow for great installation flexibility, even in multi-story buildings.

Smart Technology and Features

Control and Automation

The system includes several advanced features:

• Inverter compressor (variable speed)
• Self-diagnosis
• Auto restart
• Sleep mode
• ESP control (external static pressure)

Available Options

• WiFi module (optional)
• Smart thermostats
• Multi-zone control

At AirGreen, we often recommend adding WiFi to allow owners to control their system remotely, which is particularly useful in rental properties.

Reliability and Durability: Designed to Last

Robust Components

• GoldFin™ coating on the heat exchanger
• Brushless fan motor
• R-32 refrigerant leak detection system

The R-32 refrigerant also offers:

• Better energy efficiency
• Reduced environmental impact

Warranty

• Compressor: 10 years
• Parts: 10 years
• Labor: 0 years (option available)

AirGreen systematically offers extended warranty options to ensure complete peace of mind.

Common Mistakes to Avoid When Choosing a Similar System

Through our field experience, we observe several common mistakes:

1. Underestimating the Required Capacity

A system that is too small will lead to overconsumption and premature wear.

2. Neglecting the Installation Configuration

Not all cabinets are multi-position — this LG model offers a real advantage.

3. Ignoring the Sound Level

In confined spaces, noise quickly becomes problematic.

4. Choosing a Non-Certified Installer

Poor sizing or incorrect installation drastically reduces performance.
