Heating & cooling

Heating and cooling a home in American

Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In American, 87% of that work is heating and 13% is cooling, so the furnace matters far more than the air conditioner.

87%heating
5,926 heating degree daysMore heating than 54% of U.S. towns
850 cooling degree daysMore cooling than 51% of U.S. towns

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.
