In order to support a wider range of system types, our team has revamped the input's dropdown menu. The update includes double the options and an enhanced naming convention meant to precisely describe the HVAC system's cooling, heating, and air handling systems. User's who've become accustomed to selecting an older option may want to familiarize themselves with the new equivalent system. Use the table below to identify how your older selection maps to the new list.
