Experience the LG Difference with Inverter Heat Pump Systems

The LG 1.5 ton system offers a smart balance of modern inverter technology and reliable gas heating. This configuration pairs a high-efficiency inverter heat pump with an 80% AFUE single-stage gas furnace, providing a versatile solution that utilizes electric heating when it’s mild and switches to gas when temperatures plummet.

Key Features

  • 15 SEER2 Energy Efficiency - Meets updated regional efficiency standards, providing effective cooling performance while helping to manage summer utility costs.
  • 80% AFUE Gas Furnace - The 40,000 BTU furnace provides a reliable and cost-effective heating solution, ideal for installations where ultra-high efficiency venting is not required.
  • Inverter-Driven Compressor - The variable-speed compressor continuously adjusts its speed to match the cooling load, resulting in superior temperature stability and whisper-quiet operation.
  • Single-Stage Gas Heating - Features a straightforward, reliable gas valve design that delivers consistent heating capacity whenever the furnace is engaged.
  • R32 Refrigerant - Engineered with R32, a next-generation refrigerant that offers better heat transfer properties and a lower environmental footprint.
  • Multi-Positional Versatility - The indoor unit is designed for flexible installation, supporting upflow, downflow, or horizontal configurations to fit your specific mechanical space.

1.5 Tons

This 1.5 ton system is designed for smaller footprints, such as townhomes, apartments, or smaller residential levels. The 40,000 BTU furnace is perfectly matched to this capacity, ensuring the system provides enough airflow and heat output to maintain comfort without short-cycling or wasting energy in smaller spaces.

Inverter Technology

LG's inverter technology represents a significant leap forward from traditional fixed-speed systems. By modulating the compressor, the system avoids the energy-intensive "hard starts" of standard units. This leads to reduced mechanical wear, better humidity control in the summer, and an exceptionally consistent indoor environment.

Warranty

This system comes with a manufacturer's warranty covering key components including the compressor and internal parts. To ensure maximum protection and peace of mind, homeowners should complete the product registration process within the specified timeframe following a professional installation.

Why LG?

LG is a global pioneer in inverter-driven technology, applying the same precision found in their high-end electronics to home comfort systems. Their HVAC solutions are known for their sleek engineering, quiet operation, and long-term reliability.

By choosing an LG dual-fuel system, you are investing in a flexible heating and cooling solution. Whether you are looking to reduce your carbon footprint through heat pump usage or need the dependable "kick" of a gas furnace during a cold snap, LG provides the technology to keep your home comfortable year-round.

40,000 BTU 80% AFUE Single Stage LG Gas Furnace | 14" Width | Multi-Positional

Powerful, Consistent Home Heating

The LG LNAEA040A1 gas furnace is built to pair with LG's R32 heat pump condensers, delivering efficient heating at 80% AFUE. This single-stage, multi-speed furnace ensures reliable performance, quiet operation, and energy savings for residential applications.

QUICK FACTS

  • 40,000 BTU, 80% AFUE, single-stage furnace
  • Requires metal flue venting
  • Multi-Positional - Can be installed in upflow, downflow, and horizontal orientations
  • Multi-speed ECM blower motor
  • Can be converted to an LP furnace with a conversion kit (included with furnace)
  • Designed for use with LG's R32 evaporator coils and heat pumps

80% AFUE, 40,000 BTU

The LNAEA040A1 has a 80% AFUE efficiency rating. This means that it converts 4/5ths the fuel it uses into heat, leaving the remaining 20% vented out as a combustible byproduct. With this furnace's 40,000 BTU input, this means that 80% of that input (32,000 BTU) goes to heating your home. Please note that all 80% furnaces are required to use metal flue venting. Do not use plastic or PVC flues with this or any other 80% furnace.

A furnace this size is ideal for heating small homes in ideal climate conditions. This furnace is made to be paired with LG's heat pump condensers as part of a dual fuel system with two sources of heat. An internally-embedded communication kit is built into the heat pump that sends signals between it and the furnace, which will determine whether the heat pump or the furnace is the more efficient of the two heating options. This will lead to lower gas and power bills overall.

Single Stage Multi-Speed Furnace

The LNAEA040A1 has only one heat output. This furnace will burn at 100% output whenever gas heat is needed over the heat pump condenser's heat. Its efficient multi-speed ECM blower motor will help evenly distribute this heat throughout your home. The blower will additionally make the entire operation more quiet overall.

Durability and Reliability

LG's furnaces are built with corrosion-resistant stainless steel tubular heat exchangers that ensure longevity and efficient heat transfer. Their insulated cabinets are built with durable, heavy-gauge steel that reduces noise and heat loss, all while providing easy-access panels to their internal components as well as factory TXV connections for quicker installations. A self-diagnostic control board is built into each furnace that monitors how it performs. If any issues are detected, LED codes will be displayed as a quick reference for faster maintenance to the unit overall.

Warranty

This furnace includes a lifetime heat exchanger warranty and a 5 year parts warranty from the date of purchase. Register within 60 days of residential installation to upgrade the parts warranty terms to 10 years for the original homeowner, starting from the installation date.

LG 1.5 Ton 16 SEER2 Heat Pump Condenser | Inverter - R32

1.5 Ton Central Ducted Heat Pump with Advanced Inverter Performance and Reliable Comfort

The LG KUSXE181A heat pump condenser is designed for year-round heating and cooling. This condenser features inverter technology for superior performance. Pair it with its matching air handler for a multi-positional system with flexible installation in various orientations.

Key Features

  • 16 SEER2 High Efficiency Performance - Reduces energy consumption compared to older 10-14 SEER systems.
  • Inverter-Driven Compressor - Adjusts output in real time for more consistent temperatures and fewer hot/cold swings.
  • Cold Temperature Heating - Designed to maintain heating performance down to 4°F temperatures.
  • Matched Indoor Air Handler - Engineered for proper airflow, balanced performance, and simplified installation.
  • All-Electric Heating & Cooling - Ideal for homeowners replacing aging AC and furnace systems in areas with warmer winters.

1.5 Tons

LG's KUSXE181A heat pump condenser has an output of 1.5 tons, generally enough to heat and cool a small house in ideal climates. Please note that this condenser cannot function on its own, and it needs an indoor coil or air handler to work. While this unit is capable of cooling in outdoor temperatures as high as 118°F, it will only heat down to around 4°F. If you need heat in temperatures lower than this, a supplemental heat kit is strongly recommended in order to provide a source of straight electric heating in a compatible air handler.

Inverter Technology

LG's heat pump condensers are built with a twin rotary variable speed BLDC (Brushless Digitally Controlled) inverter compressor. This innovative technology eliminates the harsh "on-off" cycling seen on standard systems. Through this compressor, the heat pump is capable of modulating its own speed to match the real-time thermal load of your home, maintaining steady temperatures and reducing wear on mechanical components.

Efficiency Choices for Every Climate

Not all heat pumps are built the same. Depending on the climate of where you live, your best fit can depend dramatically on the efficiency of the heat pump at lower temperatures. The right fit saves you money by reducing energy bills. At 0°F, this heat pump operates at 55% efficiency, making it a great fit for moderate climates that have some chilly days.

Warranty

This condenser includes a 5-year parts warranty and 5-year compressor warranty from the date of purchase. Register within 60 days of residential installation to upgrade to a 10-year parts and 10-year compressor warranty for the original homeowner, starting from the installation date.
