The quote form takes a ZIP code; for Keller that is 76248 (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
Of the 16,462 occupied homes in Keller, 63% heat with natural gas, 0% with heating oil, 36% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4838632, checked 2026-10-19).
Gas heats 63% of Keller against electricity at 36%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Keller has about the Tarrant County oil share of 0% and 31 points less electric heat than the county's 67% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US48439, checked 2026-10-19).
Keller has 16,892 housing units, 0% built before 1940 and 10% before 1980, with 48% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4838632, checked 2026-10-19).
Keller has 3 points fewer pre-1940 homes than Tarrant County as a whole (3%) and 12 points more homes built after 2000 than the county's 36% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US48439, checked 2026-10-19).
The median Keller home was built in 1999 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4838632, checked 2026-10-19) and the median home has 7.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4838632, checked 2026-10-19).
88% of Keller homes are single-family detached, 1% are in two- to four-unit buildings and 10% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4838632, checked 2026-10-19).
With 88% detached houses and 1% in small multi-family buildings, a Keller quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 17% of Keller homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4838632, checked 2026-10-19), the landlord signs the quote in many of them.
Keller has 23 points more detached houses than Tarrant County overall (65%) and 14 points fewer five-plus-unit buildings than the county's 24% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US48439, checked 2026-10-19).
48% of Keller housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4838632, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
No electric utility is on file for Keller on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Keller is $174,950 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4838632, 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: 22F.

That 22F figure is the Tarrant County cold-day number a Keller heat pump is sized against, so ask the installer to show the system's heating output at 22F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 63% of Keller on gas and 36% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Keller home has 7.8 rooms and was built around 1999, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
