Heating and cooling a home in Williams
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Williams, 85% of that work is heating and 15% is cooling, so the furnace matters far more than the air conditioner.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.

Temperatures and rainfall come from NOAA’s gridded climate normals for Williams itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Williams 3 Sw, IN (4 mi, snow) and Oolitic Purdue Ex Fm, IN (7 mi, frost, heat and degree days).
