About 98 frost-free days a year

Heating and cooling a home in Heeney
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Heeney, 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.
