Heating and cooling a home in Peninsula
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Peninsula, 91% of that work is heating and 9% 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.
