LG Electric Furnace LGRED R32 | 1.5 Tons - 18000 BTU

A High-Performance Central HVAC Solution Adapted to Greater Montreal Winters

At AirGreen, we regularly install central systems combining electric furnaces and high-efficiency heat pumps in residences in Montreal, Laval, Longueuil, the North Shore, and the South Shore. The LG LGRED R32 Electric Furnace | 1.5 Tons - 18000 BTU is one of these modern solutions that precisely meets the needs of Quebec properties: heating performance, energy efficiency, comfort stability, and compatibility with current subsidies.

This model, combined with the KUSXA181A central heat pump, stands out for its balance of power, efficiency, and reliability. It is a system designed to operate effectively even in demanding winter conditions.

Why choose an LG electric furnace with a central heat pump?

A strategic combination for the Quebec climate

In the context of Greater Montreal, a combined system is often the smartest solution:

• The heat pump provides primary heating down to very low temperatures (up to -25°C for this model).
• The electric furnace acts as a backup when temperatures drop further or during peak demand.

This hybrid operation allows for:

• Significant reduction in energy costs
• Stable indoor comfort
• Extended equipment lifespan

Key technical data to remember

Here are the essential elements of this system:

• Cooling capacity: 18,000 BTU
• Heating power at -8°C: 13,000 BTU
• Power at -15°C: up to 24,000 BTU
• SEER2: 17.5
• HSPF2: 10.0
• COP at 47°F (≈8°C): 3.81
• Refrigerant: R-32 (more ecological and efficient)
• Airflow (CFM): up to 600 / 510 / 440
• Dehumidification: 2.75 pts/h
• Indoor sound level: as low as 29 dB(A)

This level of performance clearly places this system in the ENERGY STAR high-efficiency (cold climate) category.

A typical AirGreen installation: field experience feedback

We recently installed this model in a single-family home in Boucherville (South Shore). The client was replacing an old inefficient central system with an energy-intensive electric furnace.

Challenges encountered:

• Limited space in the mechanical room
• Existing ducts to be adapted to optimize airflow
• Noise level to be minimized (open-concept home)

Our approach:

• Installation of the LG furnace in a multiposition configuration
• Optimization of the duct network to maintain constant airflow (constant flow technology)
• Addition of acoustic insulation around critical sections

Result:

• Estimated energy bill reduction of over 30%
• Uniform thermal comfort throughout the house
• Very quiet operation, even at full capacity

Heating performance: what the numbers really mean

A point often misunderstood by homeowners concerns the variation in power based on outdoor temperature.

Here is a concrete overview based on manufacturer data:

• At 17°F (-8°C): up to 26,000 BTU
• At 5°F (-15°C): approximately 25,000 BTU
• At -4°F (-20°C): approximately 21,000 BTU
• At -13°F (-25°C): approximately 17,000 BTU

This means that even in very cold weather, the heat pump continues to provide a significant portion of the heating, which reduces reliance on the electric furnace.

Technology and design: what distinguishes this model

R-32 Refrigerant: a strategic choice

R-32 offers several advantages:

• Better energy efficiency
• Reduced environmental impact
• Better heat transfer capacity

R1 Scroll Compressor

• Increased reliability
• More stable operation
• Fewer vibrations

Brushless motor fan

• Reduced electricity consumption
• Precise airflow adjustment
• Superior durability

HVAC Installation: Common Mistakes to Avoid

At AirGreen, we regularly observe certain errors in installations made without expertise:

1. Improper sizing

A 1.5-ton system must be validated by a thermal load calculation. Installing too small or too large leads to:

• Discomfort
• Overconsumption
• Premature wear

2. Poorly adapted ducts

An imbalanced airflow (inadequate CFM) drastically reduces system efficiency.

3. Inadequate outdoor unit positioning

In Quebec, the outdoor unit must be installed:

• At least 10 to 12 inches from the ground
• Protected against snow accumulation

Available subsidies: a major advantage

This system is eligible for Hydro-Québec's LogisVert program.

• Current subsidy: $1560
• Simple process: invoice submission
• Fast reimbursement time

At AirGreen, we assist every client with the application process to maximize available aid.

Maintenance and durability

To maintain optimal performance:

Recommended maintenance:

• Annual complete cleaning (indoor + outdoor)
• Refrigerant level check
• Fan and duct inspection

Typical lifespan:

• Heat pump: 12 to 15 years
• Electric furnace: 15 to 20 years

Regular maintenance helps avoid:

• Efficiency losses
• Breakdowns during critical periods
• High repair costs
