It’s often said the only constant in life is change. In the HVACR industry, that phrase has been especially true. We saw another year of transitions in 2024 that included evolving efficiency and refrigerant regulations, changing corporate net zero targets, the continued emergence of advanced heat pumps, and the impact of artificial intelligence (AI) in building management.  Smart and sustainable Throughout these transformations, the industry continues to overcome challenges and in...

“If you don’t like the weather in New England, just wait a few minutes.” To this day, Mark Twain’s quote is used to describe quickly changing weather conditions in regions throughout the United States, United Kingdom, and elsewhere. However, in contrast to the weather, the climate change being experienced globally is creating nontraditional conditions that are much more permanent. Consequently, HVACR systems are being subjected to a new set of conditions that, if not ad...

The U.S. Department of Energy (DoE) Commercial Heat Pump Accelerator program is designed to enhance building efficiency and electrification. Running from 2024 through 2027, the program aims to overcome adoption barriers, promote advanced heat pump technologies, and create sustainable solutions for HVAC professionals. Compared with conventional packaged rooftop units (RTUs) with natural gas heating, heat pump RTUs are estimated to reduce greenhouse gas emissions and energy costs by up to 50%. F...
