Gary at a glance
Heating and cooling climate
NOAA's 1991–2020 climate normals for the INDIANA DUNES NL, IN station (about 14 miles away) show about 6,171 heating degree days and 808 cooling degree days in a typical year, with about 117 nights at or below freezing and 10 days reaching 90°F or more. Heating demand is far larger than cooling demand here, so the furnace, boiler or heat pump carries most of the load and a breakdown in a cold snap is the most pressing kind of call.
How homes in Gary are heated
According to the Census Bureau's American Community Survey, 86% of occupied homes in Gary heat mainly with utility gas and 12% with electricity. Gas-fired furnaces and boilers are the most common setup, which means igniters, flame sensors, gas valves and venting come up often on heating calls.
Housing age and HVAC systems
The median year built for housing in Gary is 1957, and about 88% of its 37,816 housing units were built before 1980. Many older homes here were built around hot-water or steam boilers and radiators, and some have had forced-air systems and central air added later, which can mean older ductwork and mixed equipment.
