Of the 19,654 occupied homes in Stillwater, 48% heat with natural gas, 0% with heating oil, 48% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4070300, checked 2026-10-19).
Gas heats 48% of Stillwater against electricity at 48%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Stillwater has about the Payne County oil share of 0% and 1 points more electric heat than the county's 47% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US40119, checked 2026-10-19).
Stillwater has 22,353 housing units, 4% built before 1940 and 44% before 1980, with 33% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4070300, checked 2026-10-19).
Stillwater has 3 points fewer pre-1940 homes than Payne County as a whole (7%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US40119, checked 2026-10-19).
The median Stillwater home was built in 1984 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4070300, checked 2026-10-19) and the median home has 4.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4070300, checked 2026-10-19).
51% of Stillwater homes are single-family detached, 8% are in two- to four-unit buildings and 31% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4070300, checked 2026-10-19).
63% of Stillwater homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4070300, checked 2026-10-19), so beside the 51% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Stillwater has 11 points fewer detached houses than Payne County overall (62%) and 11 points more five-plus-unit buildings than the county's 20% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US40119, checked 2026-10-19).
With 63% of Stillwater homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4070300, checked 2026-10-19), most heat pump quotes here are landlord-driven: the landlord signs the contract and picks the equipment, and the tenant sees the lower bill.
No electric utility is on file for Stillwater on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Power Forward with PSO residential rebates (ASHP), run by PSO (Public Service Company of Oklahoma), is a live program for Oklahoma addresses and covers qualifying equipment at $500 per system (registry row 51 verified 2026-10-14, https://powerforwardwithpso.com/programs/heat-pump/, checked 2026-10-16); confirm eligibility for the Stillwater address before counting it. With 48% of Stillwater homes already on electric heat and 51% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Stillwater is $43,700 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4070300, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: 15F.

That 15F figure is the Payne County cold-day number a Stillwater heat pump is sized against, so ask the installer to show the system's heating output at 15F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 48% of Stillwater on gas and 48% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Stillwater home has 4.7 rooms and was built around 1984, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
