In the Willamette Valley (main population area) most people have some type of air-conditioning. Just a window unit on some of the older construction. Around 20% of the homes have no cooling.
The state is pushing for heat-pump adoption on all newer builds or furnace replacements. Both for energy savings and to meet the cooling needs from increasing temps.
