Hartford / Granby
Granby is about 16 miles from the Census center point for Hartford in a straight line and covers 40.733 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).
Granby has 11,184 residents (give or take 36) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US0911032640, checked 2026-10-19), about 275 people per square mile.
The quote form takes a ZIP code; for Granby that is 06035, 06060, 06090 (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).
Granby is spread out at 275 people per square mile across 40.733 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 4,457 occupied homes in Granby, 6% heat with natural gas, 73% with heating oil, 7% with electricity and 8% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US0911032640, checked 2026-10-19).
Granby has 42 points more oil heat than Capitol Planning Region as a whole, where 31% of homes burn oil, and 9 points less electric heat than the county's 16% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US09110, checked 2026-10-19).
Heating oil is the largest single fuel in Granby at 73%, ahead of propane at 8%, 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.
The median Granby home was built in 1978 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US0911032640, 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=060XX00US0911032640, checked 2026-10-19).
Granby has 4,625 housing units, 10% built before 1940 and 54% before 1980, with 13% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US0911032640, checked 2026-10-19).
Granby has 8 points fewer pre-1940 homes than Capitol Planning Region as a whole (18%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US09110, checked 2026-10-19).
82% of Granby homes are single-family detached, 3% are in two- to four-unit buildings and 5% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US0911032640, checked 2026-10-19).
With 82% detached houses and 3% in small multi-family buildings, a Granby quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 8% of Granby homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0911032640, checked 2026-10-19), the landlord signs the quote in many of them.
Granby has 25 points more detached houses than Capitol Planning Region overall (57%) and 16 points fewer five-plus-unit buildings than the county's 21% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US09110, checked 2026-10-19).
Only 8% of Granby homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0911032640, 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 Granby 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 Granby address before counting it. With 7% of Granby homes already on electric heat and 87% 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 Granby is $120,275 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US0911032640, 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 Granby 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 what happens to the oil tank, since 73% of the 4,457 occupied Granby homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Granby home has 6.6 rooms and was built around 1978, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
