Dallas / Southlake
Southlake has 31,137 residents (give or take 291) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4869032, checked 2026-10-19), about 1,426 people per square mile.
Southlake is about 25 miles from the Census center point for Dallas in a straight line and covers 21.836 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
The quote form takes a ZIP code; for Southlake that is 76092 (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 9,229 occupied homes in Southlake, 72% heat with natural gas, 0% with heating oil, 26% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4869032, checked 2026-10-19).
Gas heats 72% of Southlake against electricity at 26%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Southlake has about the Tarrant County oil share of 0% and 41 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).
Southlake has 9,612 housing units, 0% built before 1940 and 5% before 1980, with 36% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4869032, checked 2026-10-19).
Southlake has 3 points fewer pre-1940 homes than Tarrant County as a whole (3%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US48439, checked 2026-10-19).
The median Southlake home was built in 1997 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4869032, checked 2026-10-19) and the median home has 10 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4869032, checked 2026-10-19).
94% of Southlake homes are single-family detached, 0% are in two- to four-unit buildings and 3% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4869032, checked 2026-10-19).
With 94% detached houses and 0% in small multi-family buildings, a Southlake quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 5% of Southlake homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4869032, checked 2026-10-19), the landlord signs the quote in many of them.
Southlake has 29 points more detached houses than Tarrant County overall (65%) and 21 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).
Only 5% of Southlake homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4869032, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
No electric utility is on file for Southlake 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 Southlake is $250,001 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4869032, 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. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Tarrant County row, 99% heating, PDF pages 115 to 125 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 22F figure is the Tarrant County cold-day number a Southlake 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 72% of Southlake on gas and 26% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Southlake home has 10 rooms and was built around 1997, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
