Stamford / Southport
Southport has 1,568 residents (give or take 265) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0971040, checked 2026-10-19), about 1,809 people per square mile.
Southport is about 14 miles from the Census center point for Stamford in a straight line and covers 0.867 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 Southport that is 06890 (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 736 occupied homes in Southport, 90% heat with natural gas, 2% with heating oil, 5% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0971040, checked 2026-10-19).
Gas heats 90% of Southport against electricity at 5%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Southport has 21 points less oil heat than Greater Bridgeport Planning Region as a whole, where 23% of homes burn oil, and 9 points less electric heat than the county's 14% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US09120, checked 2026-10-19).
Southport has 810 housing units, 30% built before 1940 and 68% before 1980, with 23% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0971040, checked 2026-10-19).
Southport has 6 points more pre-1940 homes than Greater Bridgeport Planning Region as a whole (24%) and 15 points more homes built after 2000 than the county's 8% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US09120, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Southport home was built in 1966 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0971040, checked 2026-10-19) and the median home has 6.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0971040, checked 2026-10-19).
53% of Southport homes are single-family detached, 15% are in two- to four-unit buildings and 23% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0971040, checked 2026-10-19).
18% of Southport homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0971040, checked 2026-10-19), so beside the 53% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
30% of Southport homes were built before 1940 and 68% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0971040, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
No electric utility is on file for Southport on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Energize CT residential heat pump rebate, run by Energize CT, is a live program for Connecticut addresses and publishes its terms without one headline figure (registry row 3 verified 2026-10-15, https://www.energizect.com/node/68091, checked 2026-10-16); confirm eligibility for the Southport address before counting it. With 5% of Southport homes already on electric heat and 94% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Southport is $159,688 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0971040, 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.

That 2F figure is the Fairfield County cold-day number a Southport heat pump is sized against, so ask the installer to show the system's heating output at 2F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 90% of Southport on gas and 5% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Southport house from before 1940 (30% of the 810 units) rarely matches a square-footage rule of thumb.
