Washington's climate, particularly in the Puget Sound region around Seattle, is transitioning. While known for its rain, summers are increasingly experiencing heat waves, making AC installation a smart investment.

When choosing an installer, look for those familiar with Washington's building codes and the specific needs of homes in diverse climates, from coastal areas to the eastern plains. Permitting can also differ between King County and other areas.
