Dallas / Allen
Allen has 110,265 residents (give or take 41) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4801924, checked 2026-10-19), about 4,176 people per square mile.
Allen is about 23 miles from the Census center point for Dallas in a straight line and covers 26.402 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 Allen that is 75002, 75013 (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).
4,176 people per square mile puts Allen in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 37,243 occupied homes in Allen, 55% heat with natural gas, 0% with heating oil, 44% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4801924, checked 2026-10-19).
Gas heats 55% of Allen against electricity at 44%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Allen has about the Collin County oil share of 0% and 6 points less electric heat than the county's 50% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US48085, checked 2026-10-19).
Allen has 39,094 housing units, 0% built before 1940 and 7% before 1980, with 60% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4801924, checked 2026-10-19).
Allen has 3 points more homes built after 2000 than the county's 57% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US48085, checked 2026-10-19).
The median Allen home was built in 2003 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4801924, checked 2026-10-19) and the median home has 6.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4801924, checked 2026-10-19).
73% of Allen homes are single-family detached, 2% are in two- to four-unit buildings and 22% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4801924, checked 2026-10-19).
With 73% detached houses and 2% in small multi-family buildings, a Allen quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 31% of Allen homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4801924, checked 2026-10-19), the landlord signs the quote in many of them.
Allen has 5 points more detached houses than Collin County overall (68%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US48085, checked 2026-10-19).
60% of Allen housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4801924, 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 Allen 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 Allen is $130,901 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4801924, 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: 20F.

That 20F figure is the Collin County cold-day number a Allen heat pump is sized against, so ask the installer to show the system's heating output at 20F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 55% of Allen on gas and 44% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Allen home has 6.9 rooms and was built around 2003, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
