About 209 frost-free days a year

Heating and cooling a home in Mount Carbon
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Mount Carbon, 80% of that work is heating and 20% 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.
