Heating and cooling a home in Williams
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Williams, 98% of that work is heating and 2% 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 Camp Norris Dnr, MN (15 mi, snow) and Baudette Intl Airport, MN (16 mi, frost, heat and degree days).
