A Compact and Efficient Solution for Precise All-Season Comfort

In the field of HVAC in Montreal, Laval, Longueuil, the North Shore, and the South Shore, certain residential and commercial configurations require specific solutions. The LG R32 12000 BTU floor console precisely meets these needs thanks to its low-profile format, high energy performance, and ability to provide stable comfort even in demanding climatic conditions.

At AirGreen, we regularly install this type of equipment in environments where classic wall-mounted units are not ideal: under windows, in spaces with reduced height, or in renovation projects where visual discretion is essential.


Why choose a floor console instead of a classic wall unit?

Adaptation to architectural constraints

The LG R32 floor console is installed at a low height, making it ideal for:

  • Finished basements
  • Rooms with sloped ceilings
  • Areas under windows
  • Heritage buildings to preserve

Unlike wall-mounted units, it allows for more homogeneous air distribution at occupancy height, which improves perceived thermal comfort.

Optimized air distribution

Thanks to its design, air is diffused upwards and downwards, creating natural circulation that limits cold or hot spots. This is particularly appreciated in multi-level homes typical of Greater Montreal.


Detailed technical specifications: controlled performance

This LG heat pump stands out with solid technical specifications, directly from manufacturer data and the official submittal:

Cooling and heating performance

  • Cooling Capacity: 12,000 BTU
  • Cooling Range: up to 13,460 BTU max
  • Heating Capacity: up to 16,600 BTU max
  • Power at -15°C: 11,400 BTU
  • COP at -8°C: high energy efficiency

This performance allows for efficient use in moderate winters, typical of southern Quebec, while offering excellent efficiency in summer air conditioning.

Energy efficiency

  • SEER2: 19.7
  • HSPF2: 10.5
  • EER2: 13

These values place this unit in a superior energy-efficient category, significantly reducing operating costs in the long term.

Quiet operation

  • Indoor sound level: up to 27 dB(A)
  • Outdoor sound level: approximately 52 dB(A)

This makes it a perfectly suited solution for bedrooms, home offices, or commercial spaces requiring a quiet environment.


Professional HVAC installation: AirGreen expertise in the field

Concrete example in Laval

During a recent project in Laval, we installed this console in a ground-floor condo. The client did not want a visible wall-mounted unit above their furniture.

Challenges encountered:

  • Limited space under a large window
  • Piping to be neatly concealed
  • Need for efficient heating in winter

AirGreen Solution:

  • Low wall installation with discreet pipe covers
  • Optimized drainage to the exterior
  • Fine calibration of the Inverter system

Result:

  • Uniform thermal comfort
  • Significant reduction in energy bills
  • Perfectly integrated aesthetics

Advanced LG Technology: Reliability and Smart Control

Variable Speed Inverter

The Inverter compressor continuously adjusts power according to real needs, which:

  • Reduces energy consumption
  • Avoids on/off cycles
  • Extends equipment lifespan

Integrated features

  • Auto-restart in case of power failure
  • Sleep mode for optimized nocturnal comfort
  • Programmable timer
  • Control lock

Optional WiFi

The addition of the WiFi module allows remote control via smartphone, ideal for:

  • Adjusting temperature before arriving
  • Monitoring consumption
  • Managing multiple zones

Installation: Essential technical elements

Electrical data

  • Voltage: 208-230V / 60Hz / 1 phase
  • MCA: 13.4 A
  • MOP: 15 A

Piping

  • Liquid line: 1/4"
  • Vapor line: 3/8"
  • Maximum length: approximately 65 feet
  • Max level difference: 49 feet

These parameters allow for great flexibility during installation in typical properties of Montreal and the South Shore.


HVAC Maintenance: Maximizing Durability

Regular maintenance is essential to maintain performance:

AirGreen Recommendations

  • Filter cleaning every 2-3 months
  • Annual full inspection
  • R-32 refrigerant level check
  • Coil cleaning

Common mistakes to avoid

  • Neglecting annual maintenance
  • Installing the unit in a poorly ventilated space
  • Undersizing the equipment

R-32 Refrigerant: A Strategic Choice

R-32 is a more environmentally friendly gas than R-410A:

  • Less environmental impact
  • Better thermal efficiency
  • Reduced charge quantity

This is part of a responsible approach, increasingly sought after by customers in Greater Montreal.


Subsidies and Profitability

Currently, this unit is not eligible for a LogisVert subsidy, but its energy efficiency largely compensates:

  • Savings on bills
  • Extended lifespan
  • Low maintenance
