LG won the 2025 AHR Innovation Award for its residential cold-climate heat pump, and the company is betting heavily on the category. The RED Series maintains full heating capacity at -13°F and operates at reduced capacity down to -31°F - numbers that match or exceed Mitsubishi's H2i technology. LG's partnership with the University of Alaska through the Consortium for Advanced Heat Pump Research signals serious long-term commitment to cold-climate engineering.

The HVAC division operates as LG Air Conditioning Technologies, separate from the consumer electronics business most people associate with the LG name. U.S. operations run out of Alpharetta, Georgia. LG pioneered Variable Refrigerant Flow (VRF) technology for commercial buildings and has pushed that expertise into residential products, particularly multi-zone systems.

LG adopted low-GWP R32 refrigerant earlier than most competitors, ahead of regulatory requirements. The company was named Most Sustainable Brand in HVAC by Green Builder Media. Whether sustainability factors into your purchasing decision or not, the early R32 adoption means LG equipment won't face refrigerant phase-out issues as soon as systems using older refrigerants.
