Heating & cooling

Heating and cooling a home in Clio

Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Clio, 88% of that work is heating and 12% is cooling, so the furnace matters far more than the air conditioner.

88%heating
6,363 heating degree daysMore heating than 63% of U.S. towns
874 cooling degree daysMore cooling than 53% 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.
