Energy efficiency remains a central trend in the industry. Consumers and businesses are increasingly demanding systems that reduce energy consumption and operational costs. Inverter technology, variable refrigerant flow (VRF) systems, and the use of low-global warming potential (GWP) refrigerants contribute to improved efficiency. Multi-zone air conditioning systems, including ductless mini-splits and VRF technology, are gaining popularity. They allow for more precise zoning, reducing energy waste and improving comfort in various areas of a building.
