Heating and cooling a home in Maricopa Colony
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Maricopa Colony, 20% of that work is heating and 80% is cooling, so air conditioning is the bigger bill.
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.
