Heating and cooling a home in Copper Mountain
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Copper Mountain, 100% of that work is heating and 0% 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 Copper Mountain itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Breckenridge, CO (8 mi, snow) and Climax, CO (8 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
