Ranked from NOAA 1991-2020 Climate Normals
Highest Heating Demand in Arizona
Heating degree days measure how far and how long the outside temperature sits below 65°F across a year, which is the closest single number to how much heat a house has to make. Figures are NOAA 1991-2020 Climate Normals from the weather station nearest each county seat, so they describe a thirty-year average rather than any single year.

Every figure is modelled on the county's own median home with 20% down at 7.03%. Property tax and electricity are county and state specific; homeowners insurance uses the NAIC average premium for that state, which ranges from 0.16% of home value in Hawaii to 1.16% in Oklahoma. Maintenance and water are national estimates. Full methodology.
