Frankfort at a glance
Heating and cooling climate
NOAA's 1991–2020 climate normals for the PARK FOREST, IL station (about 10 miles away) show about 6,350 heating degree days and 859 cooling degree days in a typical year, with about 126 nights at or below freezing and 16 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.
