A high-performance central HVAC solution designed for Quebec's harsh winters

At AirGreen, we install central HVAC systems capable of meeting the demanding climate realities of Montreal, Laval, Longueuil, the North Shore, and the South Shore. The LG LGRED R32 2.5-ton (30,000 BTU) electric furnace fits perfectly into this approach: robust, high-performance equipment designed to operate efficiently even when temperatures drop drastically.

This system is not limited to a simple electric furnace. It is a complete solution combined with an LG central heat pump (KUSXA301A), offering an optimal balance between heating and cooling, while maximizing energy savings.


Thermal performance adapted to the realities of Greater Montreal

Reliable heating capacity down to -25°C

In the Quebec context, actual low-temperature heating capacity is a determining factor. This LG LGRED model offers:

  • Nominal capacity: 30,000 BTU
  • Power at -8°C: 21,600 BTU
  • Power at -15°C: up to 33,000 BTU
  • Stable operation down to -25°C

During our installations on the South Shore, particularly in Boucherville and Longueuil, we found that this system maintains a constant indoor temperature even during prolonged cold spells, without excessive reliance on auxiliary heating.

Airflow and uniform comfort

The system offers high and stable airflow:

  • Up to 875 CFM (high speed)
  • Constant ventilation thanks to Constant Flow mode

This ensures homogeneous heat distribution throughout the house, even in configurations with multiple floors or longer ducts.


Advanced energy efficiency and real savings

ENERGY STAR certified performance (cold climate)

This model is certified:

  • ENERGY STAR
  • ENERGY STAR Cold Climate

With impressive performance:

  • SEER2: 18.2
  • HSPF2: 9.8
  • COP: 4.01 at 8°C

In several projects completed in Laval and on the North Shore, our clients have observed a noticeable reduction in their energy bills, particularly when replacing traditional electric systems or older generation heat pumps.

LogisVert grant available

This system is eligible for a provincial grant of up to $2592, making it a very attractive option for homeowners wishing to modernize their HVAC system while reducing their initial investment.


Technical design and advanced features

R-32 Technology: more ecological and efficient

The system operates with R-32 refrigerant, known for:

  • Its low environmental impact
  • Better energy efficiency
  • Increased performance in cold conditions

At AirGreen, we are increasingly favoring R-32 systems in our installations in Montreal to meet new environmental standards.

High-quality components

  • R1 Scroll compressor
  • Heat exchanger in copper with aluminum fins
  • Gold Fin™ coating for improved corrosion resistance
  • Dual axial outdoor fans

These elements ensure exceptional durability, even in urban environments exposed to humidity and salt.


HVAC Installation: AirGreen's field expertise

Real-life installation example in Laval

We recently installed this model in a single-family home in Laval. The client was facing several issues:

  • Uneven temperature between the ground floor and the upper floor
  • High energy consumption
  • Aging system inefficient in winter

After installation:

  • Stable temperature in all rooms
  • Reduced electricity consumption
  • Immediate improved comfort

Frequent challenges and solutions

During the installation of this type of system, we often encounter:

  • Existing poorly sized ducts
  • Restricted space for the indoor unit
  • Difficult optimal outdoor positioning

Thanks to our experience, we adapt each installation:

  • Airflow adjustment (CFM)
  • Ductwork optimization
  • Installation on anti-vibration mounts

Dimensions, installation, and compatibility

Compact dimensions for easy integration

  • Indoor unit: 21 x 21.38 x 55.19 inches
  • Outdoor unit: 37.41 x 13 x 54.34 inches

These dimensions allow installation in most residential mechanical rooms, even in restricted spaces typical of Montreal properties.

Electrical specifications

  • Voltage: 220V
  • MCA: 32A
  • MOP: 35A

Our teams systematically check the electrical panel's capacity before installation to avoid any overload.


Acoustic comfort and quality of life

Reduced noise level

  • Indoor: 35 to 40 dB(A)
  • Outdoor: approximately 54 dB(A)

This sound level is particularly appreciated in residential areas of Longueuil and Montreal, where noise pollution can quickly become problematic.


HVAC maintenance and durability

Recommended maintenance

To ensure optimal performance:

  • Annual coil cleaning
  • Refrigerant level check
  • Duct and airflow inspection

At AirGreen, we offer comprehensive HVAC maintenance plans tailored to this type of system.

Lifespan and warranty

  • Warranty: 10 years (compressor and parts)
  • Extension option available

Our clients particularly appreciate the long-term reliability of this model, especially in multi-dwelling installations.
