New Milford is about 40 miles from the Census center point for Hartford in a straight line and covers 61.563 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 Milford that is 06755, 06776 (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).
New Milford is spread out at 460 people per square mile across 61.563 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 10,667 occupied homes in New Milford, 2% heat with natural gas, 57% with heating oil, 26% with electricity and 8% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US0919052630, checked 2026-10-19).
Heating oil is the largest single fuel in New Milford at 57%, ahead of electricity at 26%, 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.
New Milford has 21 points more oil heat than Western Connecticut Planning Region as a whole, where 36% of homes burn oil, and 3 points more electric heat than the county's 23% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US09190, checked 2026-10-19).

The median New Milford home was built in 1975 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US0919052630, checked 2026-10-19) and the median home has 6.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US0919052630, checked 2026-10-19).
76% of New Milford homes are single-family detached, 5% are in two- to four-unit buildings and 14% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US0919052630, checked 2026-10-19).
With 76% detached houses and 5% in small multi-family buildings, a New Milford quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 20% of New Milford homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0919052630, checked 2026-10-19), the landlord signs the quote in many of them.
New Milford has 19 points more detached houses than Western Connecticut Planning Region overall (57%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US09190, checked 2026-10-19).
No electric utility is on file for New Milford 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 Milford address before counting it. With 26% of New Milford homes already on electric heat and 67% 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 New Milford is $106,411 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US0919052630, 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 Litchfield County cold-day number a New Milford 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 57% of the 10,667 occupied New Milford homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median New Milford home has 6.4 rooms and was built around 1975, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
