Deer Park has 33,967 residents (give or take 42) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4819624, checked 2026-10-19), about 3,233 people per square mile.
The quote form takes a ZIP code; for Deer Park that is 77536 (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).
3,233 people per square mile puts Deer Park in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 11,999 occupied homes in Deer Park, 69% heat with natural gas, 0% with heating oil, 29% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4819624, checked 2026-10-19).
Deer Park has about the Harris County oil share of 0% and 26 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 69% of Deer Park against electricity at 29%, 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 Deer Park home was built in 1982 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4819624, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4819624, checked 2026-10-19).
Deer Park has 12,895 housing units, 1% built before 1940 and 46% before 1980, with 28% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4819624, checked 2026-10-19).
Deer Park has 8 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).
78% of Deer Park homes are single-family detached, 3% are in two- to four-unit buildings and 12% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4819624, checked 2026-10-19).
With 78% detached houses and 3% in small multi-family buildings, a Deer Park quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 22% of Deer Park homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4819624, checked 2026-10-19), the landlord signs the quote in many of them.
Deer Park has 21 points more detached houses than Harris County overall (57%) and 20 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 Deer Park 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 Deer Park is $100,382 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4819624, 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 Deer Park 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 69% of Deer Park on gas and 29% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Deer Park home has 6 rooms and was built around 1982, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
