4 Ton High Efficiency Single Zone Condenser

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

The high efficiency LG KUSXB481A 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

  • 18 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 Climate Heating - Designed to maintain reliable 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 KUSXB481A 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. This unit is capable of cooling in outdoor temperatures as high as 118°F and heating down to -4°F. Supplemental heat kits are available if backup electric heat is necessary for your area.

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 68% efficiency, making it a good fit for maximizing efficiency in the coldest climates.

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.
