Variability: Efficiency Tweaks for Your A/C

A/C systems can be set up to use 30-50% less power if variable control technologies such as variable speed drives (VSD), variable air volume (VAV), and variable refrigerant flow (VRF) are used. These technologies allow A/C systems to operate efficiently at part-load, lowering energy use and extending lifetimes. Find out more about how these can fit into your current site with our guidelines on the relative advantages for each type.
