How Indiana conditions shape HVAC planning
Indiana planning must account for humid summers, freezing winters, tornado risk and mixed fuel choices. Both heating and cooling design conditions, shoulder-season humidity, duct performance and control changeover matter in mixed climates.
Climate describes likely loads; it does not size equipment. Ask for property-specific load calculations, duct or distribution findings, design temperatures and documented startup measurements when they apply.

Review the peer-reviewed NOAA Indiana State Climate Summary for observed climate trends and state-specific extreme-weather context. Degree-day and design-temperature decisions should use the serving location and current code documents, not a statewide average.
