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

5,572 heating degree daysLess heating than 54% 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.
