Stillwater's climate (IECC zone 3A-Warm-Humid) keeps outdoor temps inside the efficient range of air-source heat pumps most of the year, with January averages around 46°F. That's why heat-pump conversions have overtaken straight AC + furnace installs in most of the local market. Properly sized equipment matched to Stillwater's load profile runs quieter, lasts longer, and avoids the short-cycling that kills cheap installs. OG&E (Oklahoma Gas and Electric)'s OG&E Home Energy Efficiency — Heat Pump Rebate currently offers up to $1,000 toward a qualifying system, which meaningfully shifts the cost-of-ownership math.
