Hartford / Woodbridge
Woodbridge has 9,073 residents (give or take 21) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US0917087700, checked 2026-10-19), about 482 people per square mile.
Woodbridge is about 32 miles from the Census center point for Hartford in a straight line and covers 18.812 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 Woodbridge that is 06525 (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).
Woodbridge is spread out at 482 people per square mile across 18.812 square miles of land, so a long refrigerant line run between the outdoor unit and the farthest indoor head is the sizing question an installer checks first.
Of the 3,260 occupied homes in Woodbridge, 10% heat with natural gas, 73% with heating oil, 6% with electricity and 6% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US0917087700, checked 2026-10-19).
Heating oil is the largest single fuel in Woodbridge at 73%, ahead of gas at 10%, so the usual job here is an oil boiler or furnace coming out and a cold-climate heat pump going in, with the oil tank removed.
Woodbridge has 43 points more oil heat than South Central Connecticut Planning Region as a whole, where 30% of homes burn oil, and 12 points less electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US09170, checked 2026-10-19).
Woodbridge has 3,498 housing units, 11% built before 1940 and 67% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US0917087700, checked 2026-10-19).
Woodbridge has 12 points fewer pre-1940 homes than South Central Connecticut Planning Region as a whole (23%) and 3 points fewer homes built after 2000 than the county's 10% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US09170, checked 2026-10-19).
The median Woodbridge home was built in 1967 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US0917087700, checked 2026-10-19) and the median home has 8.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US0917087700, checked 2026-10-19).
90% of Woodbridge homes are single-family detached, 2% are in two- to four-unit buildings and 6% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US0917087700, checked 2026-10-19).
With 90% detached houses and 2% in small multi-family buildings, a Woodbridge quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 7% of Woodbridge homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0917087700, checked 2026-10-19), the landlord signs the quote in many of them.
Woodbridge has 37 points more detached houses than South Central Connecticut Planning Region overall (53%) and 16 points fewer five-plus-unit buildings than the county's 22% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US09170, checked 2026-10-19).
Only 7% of Woodbridge homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0917087700, 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.
67% of Woodbridge homes were built before 1980 and only 7% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US0917087700, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
United Illuminating lists Woodbridge among the Connecticut communities it serves for electricity (United Illuminating service area, https://www.uinet.com, checked 2026-10-19).
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 Woodbridge address before counting it. With 6% of Woodbridge homes already on electric heat and 89% 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 Woodbridge is $188,750 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US0917087700, 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 New Haven County cold-day number a Woodbridge 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 what happens to the oil tank, since 73% of the 3,260 occupied Woodbridge homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Woodbridge home has 8.2 rooms and was built around 1967, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
