Hartford / New London
New London has 27,625 residents (give or take 51) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US0918052350, checked 2026-10-19), about 4,927 people per square mile.
New London is about 43 miles from the Census center point for Hartford in a straight line and covers 5.607 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 New London that is 06320 (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).
Median household income in New London is $59,098 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US0918052350, 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.
4,927 people per square mile puts New London in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
30% of New London homes are single-family detached, 30% are in two- to four-unit buildings and 34% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US0918052350, checked 2026-10-19).
64% of New London homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0918052350, checked 2026-10-19), so beside the 30% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
New London has 31 points fewer detached houses than Southeastern Connecticut Planning Region overall (61%) and 18 points more five-plus-unit buildings than the county's 16% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US09180, checked 2026-10-19).
With 64% of New London homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0918052350, checked 2026-10-19), most heat pump quotes here are landlord-driven: the landlord signs the contract and picks the equipment, and the tenant sees the lower bill.
Of the 11,794 occupied homes in New London, 42% heat with natural gas, 21% with heating oil, 30% with electricity and 5% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US0918052350, checked 2026-10-19).
Gas leads in New London at 42%, but 26% of homes still burn delivered oil or propane, and those 3,066 or so homes are where a heat pump pays back fastest.
New London has 28 points less oil heat than Southeastern Connecticut Planning Region as a whole, where 49% of homes burn oil, and 8 points more electric heat than the county's 22% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US09180, checked 2026-10-19).
No electric utility is on file for New London 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 New London address before counting it. With 30% of New London homes already on electric heat and 68% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
New London has 12,737 housing units, 47% built before 1940 and 83% before 1980, with 8% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US0918052350, checked 2026-10-19).
New London has 23 points more pre-1940 homes than Southeastern Connecticut Planning Region as a whole (24%) and 7 points fewer homes built after 2000 than the county's 15% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US09180, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median New London home was built in 1945 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US0918052350, checked 2026-10-19) and the median home has 4.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US0918052350, checked 2026-10-19).
47% of New London homes were built before 1940 and 83% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US0918052350, 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.

That 7F figure is the New London County cold-day number a New London heat pump is sized against, so ask the installer to show the system's heating output at 7F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 42% of New London on gas and 30% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a New London house from before 1940 (47% of the 12,737 units) rarely matches a square-footage rule of thumb.
