Heat Grips East US Amid AC Divide
4 Jul
Summary
- Alaska and Hawaii have highest AC, no access.
- Southeast US has near-universal AC access.
- Heat dome brings dangerous heat to the East.

A severe heatwave is impacting much of the eastern United States as a heat dome brings dangerously high temperatures. Millions of Americans are experiencing conditions 10 to 20 degrees above average, with extreme heat warnings in effect across numerous states. This situation highlights significant differences in air conditioning access across the country, according to Census Bureau estimates.
Data indicates that Alaska and Hawaii have the highest percentages of households without air conditioning. Conversely, states in the Southeast, including Florida, Georgia, Alabama, and Louisiana, report less than one percent of occupied households lacking AC. The Midwest and South Census regions show the highest overall AC usage, while the West, particularly coastal areas, reports lower rates.
