Recommended unit for Stillwater
Given Oklahoma’s mixed-humid climate and gas heating, high-seer2 ac + gas furnace is the sensible default for most Stillwater homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.
