Houston / Humble
Humble has 16,521 residents (give or take 40) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4835348, checked 2026-10-19), about 1,667 people per square mile.
Humble is about 16 miles from the Census center point for Houston in a straight line and covers 9.912 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 Humble that is 77338 (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).
Median household income in Humble is $57,011 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4835348, 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.
42% of Humble homes are single-family detached, 11% are in two- to four-unit buildings and 34% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4835348, checked 2026-10-19).
61% of Humble homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4835348, checked 2026-10-19), so beside the 42% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Humble has 15 points fewer detached houses than Harris County overall (57%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US48201, checked 2026-10-19).
With 61% of Humble homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4835348, 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.
Of the 5,981 occupied homes in Humble, 33% heat with natural gas, 0% with heating oil, 65% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4835348, checked 2026-10-19).
Electricity already heats 65% of Humble homes, ahead of gas at 33%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Humble has about the Harris County oil share of 0% and 10 points more electric heat than the county's 55% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US48201, checked 2026-10-19).
No electric utility is on file for Humble on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Humble has 6,428 housing units, 7% built before 1940 and 44% before 1980, with 18% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4835348, checked 2026-10-19).
Humble has 4 points more pre-1940 homes than Harris County as a whole (3%) and 18 points fewer homes built after 2000 than the county's 36% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US48201, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Humble home was built in 1982 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4835348, checked 2026-10-19) and the median home has 4.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4835348, checked 2026-10-19).
Heating design temperature: 29F.

That 29F figure is the Harris County cold-day number a Humble heat pump is sized against, so ask the installer to show the system's heating output at 29F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Humble home has 4.9 rooms and was built around 1982, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
