2025 AHR innovation award for residential cold climate heat pump 

LG Electronics has been honoured with the 2025 AHR Innovation Award in the Sustainable Solutions category for its advanced LG Residential Cold Climate Heat Pump. Heat pump delivers advanced efficiency and heating performance in extreme cold conditions

The innovative heat pump incorporates a refrigerant cycle that prevents frost accumulation on the outdoor heat exchanger, thereby enhancing heating performance. The solution is also equipped with a high-capacity, high-efficiency twin rotary inverter compressor that uses low Global Warming Potential (GWP) R32 (GWP 675) refrigerant, available with HSPF2 13.4 Btu/Wh and 13.6 kBtu/h.

The LG Residential Cold Climate Heat Pump will be featured at AHR Expo 2025 in Orlando next February. It offers opportunities to reduce energy consumption and carbon emissions while improving inhabitants’ comfort.

Designed specifically for cold regions, LG’s heat pump operates effectively at temperatures as low as negative 35 degrees Celsius (negative 31 degrees Fahrenheit). It retains full heating capacity at negative 25 degrees Celsius (negative 13 degrees Fahrenheit) and functions at 70 percent capacity at negative 35 degrees Celsius (negative 31 degrees Fahrenheit). Additionally,

James Lee, head of the Air Solution Business Unit at LG Home Appliance & Air Solution Company said, “The recognition from ASHRAE and AHR reflects LG’s ongoing dedication to HVAC technological innovation and electrification. The Residential Cold Climate Heat Pump is a solution that can withstand extreme cold weather conditions and help improve energy efficiency in homes. Our focus remains on creating more environmentally responsible solutions that align with consumer needs while simultaneously reducing our global environmental footprint.”

Lee says, “We understand the need to develop and validate products under extreme cold conditions, and the award-winning LG Residential Cold Climate Heat Pump is a testament to our ongoing efforts in this important area. By minimizing reliance on fossil fuel-driven heating systems and cutting down on any supplementary back-up heating, the heat pump reduces environmental impacts and supports the larger decarbonisation and electrification movements.”

LG’s comprehensive suite of heating and cooling solutions for commercial, light-commercial and residential applications continues to receive industry recognition. This is largely due to LG’s consistent efforts to provide innovative HVAC solutions leveraging the company’s advanced core technologies, which elevate performance and support the move to electrification. The award was decided by an independent panel of ASHRAE member judges, who assessed product entries based on their design, creativity, application, value and market impact potential.
