Variable refrigerant flow (VRF) technology is moving further into the mainstream, driven by flexibility and built-in intelligence. In this video, Doug Bougher, director of applied VRF sales at LG, explains that VRF is more than just heating and cooling — it’s a fully integrated zoning and controls solution. Because heat exchange happens through small refrigerant piping instead of large duct systems, VRF is one of the least intrusive HVAC options for buildings, making it attractive for both new construction and retrofits.

But with that sophistication comes responsibility. Controls are king in today’s HVAC systems, and VRF blends hardware with advanced control algorithms, including AI-driven technology. Proper training and commissioning are essential.
