Whole-home heating in Illinois
In Illinois, heating systems run for months at a time (IECC zone 5 at the coldest), so weaknesses in ducts and controls cost real money. A leaky duct run in an unheated attic loses the most heat when the attic is coldest, which in Illinois is most of the winter.
Common heating fuels here: natural gas. Fuel-burning systems dominate, so controls, ducts and airflow are where most whole-home heating problems show up.
Polar vortex events have pushed Chicago-area wind chills far below zero, the kind of cold that exposes weak furnaces. A whole-home check covers the thermostat, the heat source, ducts and returns, so the fix reaches the rooms that are actually cold.
