According to the U.S. Energy Information Agency, Wyoming ranks 45th in the nation for air conditioning, with roughly 71% to 79% of households having an air conditioning unit. The state’s mild summers and high elevation contribute to the low usage rate.

Low AC Usage Rates

The high altitude and dry continental climate mean many residents only experience a few weeks of peak summer heat, making an HVAC system an optional luxury rather than an absolute necessity. Older homes, particularly those built before the 1940s, were designed with architectural features to maximize cooling without electricity, such as high ceilings, thick walls, and expansive porches.

Nationwide, nearly 90% of U.S. households use air conditioning, but the numbers vary significantly by location. The states with the highest percentage of air conditioning per household are Florida, Delaware, Oklahoma, Alabama, and Louisiana, with over 99% of households having an air conditioning unit.
