LG 4 Ton 14.3 SEER2 Heat Pump with 21" Multi-Positional Cased Coil | Inverter - R32

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

The LG KUSXE481A 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.

4 Tons

LG's KUSXE481A heat pump condenser has an output of 4 tons, generally enough to heat and cool a medium to large 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.

OVERVIEW

LG delivers reliable HVAC performance with the LKMMA48C1 A-coil, designed for seamless integration in R32 dual fuel heat pump and furnace systems. This 4-ton 21" coil maintains system efficiency through factory engineering, multi-position flexibility, and compatibility with LGRED technology for optimized cooling and heating.

QUICK FACTS

• 4 ton A-coil for R32 systems
• Multi-Positional: upflow, downflow, horizontal
• Aluminum fins with mechanically bonded design
• Compatible with LG heat pump condensers
• Can be paired with LG furnaces or your existing furnace
• R32 refrigerant-ready with corrosion-resistant features

4 Tons

The LG LKMMA48C1 provides an output of 4 tons when paired with a compatible LG condenser. In some cases, the coil will be smaller in size compared to its compatible LG condenser. While in most setups this would not be permissible, each of these pairings are AHRI-rated and they can be safely used in your home. Please note that this item cannot operate independently from a compatible condenser and furnace, each available at an additional cost.

Warranty

LG offers a 5-year limited parts warranty standard, extendable to 10 years on parts with timely online registration by an authorized installer. Labor coverage applies for 2 years; extended terms require certified system matchup and code-compliant installation.

Line sets are the copper lines which connect an outdoor condensing unit/heat pump to an inside air handler or evaporator coil. Line sets are available in different lengths and diameters to fit most applications.
