Catering to commercial, light-commercial and residential applications, LG Electronics USA’s Air Conditioning Technologies division highlighted the company’s commitment to improved decarbonization and electrification technologies that are “ahead of the expected.” Throughout the show, LG demonstrated its leadership in heat pump advancement through cold climate research and innovations, delivering the latest heating, cooling, water and integrated control solutions.
LG heat pump innovations supporting decarbonization
Within the booth, LG showcased Home Electrification and Innovation Zones, both featuring a variety of LG’s advanced HVAC systems and solutions:
- The LG Residential Cold Climate Heat Pump, winner of the 2025 AHR Innovation Award in the Sustainable Solutions Category, is a heat pump solution for cold climates that uses a low-GWP refrigerant cycle to retain full heating capacity at -13°F (-25°C) and functions at 70 percent capacity even at -31°F (-35°C).
- LG ARTCOOL Deluxe, with Dual Vane technology for precise airflow, features Soft Air for gentle cooling, Freeze Cleaning for healthier air and Auto Clean+ for system maintenance; an Occupancy Sensor for energy efficiency, which adjusts temperature settings based on presence to maximize comfort and minimize energy use; and R32 refrigerant for lower global warming potential.
- LG Inverter Heat Pump Water Heater packages innovative inverter and heat pump motor technology into a sleek, ENERGY STAR certified water heating solution, minimizing the need for supplemental electric resistance heat, supporting electrical consumption savings across wider heating operating ranges of 23°F to 120°F (ambient temperature), and bringing state-of-the-art innovation to something as familiar as water heating. New 58- and 80-gallon models feature demand response and water leakage detection sensors.
- The LG A-Coil/Furnace combines the proven technology of an LG Inverter Heat Pump with an A-Coil and Gas Furnace, delivering dual-fuel effective cooling and heating and efficient management with the stable performance of an LG heat pump.
Many of LG’s HVAC solutions are ENERGY STAR certified, offering customers the opportunity to potentially take advantage of the growing number of federal, local, and utility rebates and incentives, which can help make an efficient heat pump system more accessible and affordable while capturing the long-term benefit of the technology.
LG Electronics USA Senior Vice President Steve Scarbrough, general manager of LG Air Conditioning Technologies, remarked:
LG is paving the way for technological innovation and electrification in the HVAC industry, demonstrated by our inverter heat pump technology and groundbreaking consortium research with the University of Alaska, among other advancements. Our presence at this year’s AHR is focused on efficient technologies that can be used in a variety of extreme climates, providing our customers with effective solutions that help them save money while also bettering the planet.
Advanced chiller technologies targeting data centers
Capitalizing on its HVAC chiller innovations in 2025, LG is joining forces with Microsoft in the rapidly growing field of artificial intelligence (AI) data centers. With LG’s thermal management systems and advanced chiller technologies optimized for AI data centers, this new alliance aims to enhance energy efficiency in these critical backbones of AI infrastructure. Together, the companies plan to create next-generation data centers that are more efficient and sustainable. LG chillers on display at AHR Expo 2025 included:
- Centrifugal Chiller is an oil-free, inverter centrifugal chiller that enhances efficiency by eliminating oil from the refrigerant cycle, making repairs direct and swift, and helping ensure easy chiller part supply. It features improved magnetic bearing reliability through precise rotor control and online UPS for continuous power supply. The chiller also incorporates Discharge Gas Recirculation for fast restarts and enhanced availability. With a simpler structure, it offers fine refrigerant flow control and machine learning functions to reduce surges, restoring 75 percent capacity within 90 seconds.
- Inverter Scroll Heat Pump Chiller is a compact air-cooled Inverter Scroll Heat Pump Chiller that optimizes heating and cooling while enabling easy installation and quiet operation. Heating and cooling efficiency is improved by increased air volume, optimized airflow, and reduced noise while maintaining heat exchange performance and a stable refrigeration cycle in frosty conditions while supplying water from -10 to 60°C.
Additional highlights on display throughout LG’s Innovation Zones included:
- LATS HVAC LITE is a preliminary design tool for engineers working on Multi V (R-32 VRF) systems, which includes Multi V heat recovery systems, with future versions set to incorporate Multi V S systems. Currently exclusive to LG employees and partners, it provides data such as unit type, cooling and heating capacities, refrigerant type, voltage-hertz-phase, pipe diameters and maximum number of connected IDUs.
- LATS R-Checker is a web-based tool that calculates a system’s releasable charge and maximum charge for a space per UL 60335-2-40 4th edition. It can account for the use of release mitigation controls, such as addition of shutoff valves and use of air circulation or ventilation.
- 1-Way Cassette is ceiling mounted, discharging air in one direction, and includes a factory-installed filter, delivering cost-effective comfort. Additionally, its 13.5-inch-depth Slim Body offers a minimal exposure design.
At the AHR Show, LG gave hourly interactive presentations throughout the show, including discussions on Hydronics, Chillers, Electrification, and Cold Climate Heat Pump Technology.
