Houston / Spring
Spring is about 19 miles from the Census center point for Houston in a straight line and covers 22.49 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).
Spring has 68,580 residents (give or take 4,281) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4869596, checked 2026-10-19), about 3,049 people per square mile.
The quote form takes a ZIP code; for Spring that is 77373 (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).
3,049 people per square mile puts Spring in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 22,336 occupied homes in Spring, 50% heat with natural gas, 0% with heating oil, 46% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4869596, checked 2026-10-19).
Spring has about the Harris County oil share of 0% and 9 points less 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).
Gas heats 50% of Spring against electricity at 46%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
The median Spring home was built in 1993 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4869596, checked 2026-10-19) and the median home has 6.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4869596, checked 2026-10-19).
Spring has 23,546 housing units, 0% built before 1940 and 30% before 1980, with 46% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4869596, checked 2026-10-19).
Spring has 3 points fewer pre-1940 homes than Harris County as a whole (3%) and 10 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=050XX00US48201, checked 2026-10-19).
46% of Spring housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4869596, 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.
86% of Spring homes are single-family detached, 3% are in two- to four-unit buildings and 7% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4869596, checked 2026-10-19).
With 86% detached houses and 3% in small multi-family buildings, a Spring quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 26% of Spring homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4869596, checked 2026-10-19), the landlord signs the quote in many of them.
Spring has 29 points more detached houses than Harris County overall (57%) and 25 points fewer five-plus-unit buildings than the county's 32% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US48201, checked 2026-10-19).
No electric utility is on file for Spring 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 Spring is $88,997 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4869596, 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: 29F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Harris 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 29F figure is the Harris County cold-day number a Spring 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 whether the quote is whole-home or partial-home, because with 50% of Spring on gas and 46% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Spring home has 6.2 rooms and was built around 1993, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
