The quote form takes a ZIP code; for South Windsor that is 06074 (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 9,835 occupied homes in South Windsor, 51% heat with natural gas, 29% with heating oil, 13% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US0911071390, checked 2026-10-19).

Gas leads in South Windsor at 51%, but 31% of homes still burn delivered oil or propane, and those 3,049 or so homes are where a heat pump pays back fastest.
The median South Windsor home was built in 1980 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US0911071390, checked 2026-10-19) and the median home has 6.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US0911071390, checked 2026-10-19).
South Windsor has 10,272 housing units, 7% built before 1940 and 50% before 1980, with 17% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US0911071390, checked 2026-10-19).
South Windsor has 11 points fewer pre-1940 homes than Capitol Planning Region as a whole (18%) and 6 points more homes built after 2000 than the county's 11% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US09110, checked 2026-10-19).
70% of South Windsor homes are single-family detached, 6% are in two- to four-unit buildings and 13% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US0911071390, checked 2026-10-19).
With 70% detached houses and 6% in small multi-family buildings, a South Windsor quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 15% of South Windsor homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0911071390, checked 2026-10-19), the landlord signs the quote in many of them.
South Windsor has 13 points more detached houses than Capitol Planning Region overall (57%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US09110, checked 2026-10-19).
Only 15% of South Windsor homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0911071390, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
No electric utility is on file for South Windsor 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 South Windsor address before counting it. With 13% of South Windsor homes already on electric heat and 82% 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 South Windsor is $144,961 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US0911071390, 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 0F figure is the Hartford County cold-day number a South Windsor heat pump is sized against, so ask the installer to show the system's heating output at 0F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 51% of South Windsor on gas and 13% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median South Windsor home has 6.6 rooms and was built around 1980, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
