Regional cost guide
Oklahoma mini-split cost guide
Much of Oklahoma is climate zone 3A / 4A / 4B (Panhandle). Electricity here runs 14.33 cents per kilowatt-hour, so a typical 12,000 BTU system costs about $427 a year to run. 15 rebate programs below can cut the installed price. Installed prices are mostly national — labor is the part that varies locally.
