Heating and cooling a home in Stirling
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Stirling, 79% of that work is heating and 21% is cooling.
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 Stirling itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at De Sabla, CA (5 mi) away. Normals are 30-year averages, not a forecast.
