Why state matters for winter heating

Climate zone, common heating fuels and the age of local housing change which problems show up. A Minnesota furnace, a Georgia heat pump and a Boston steam boiler fail in different ways. Each state page explains what's typical there.

Climate zones on these pages come from the International Energy Conservation Code (IECC) map used by the U.S. Department of Energy. Heating fuel patterns reflect U.S. Energy Information Administration survey data.
