HVAC used in U.S. commercial buildings

In the six years up to 2019, the United States heating, ventilation, and air conditioning (HAVC) industry witnessed a period of growth as several zones - such as VAV and VRF - grew substantially. VRF or variable refrigerant flow experienced a faster growth than the overall market, with an annual growth 50 percent in 2017. The source mentions that by 2019, there ware roughly 6,700 VRF projects. VAV or variable air volume was quite common on the U.S. East Coast and overall mirrored the overall market developments.
