Worcester / Deerfield
Deerfield has 5,158 residents (give or take 19) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2501116670, checked 2026-10-19), about 159 people per square mile.
Deerfield is about 45 miles from the Census center point for Worcester in a straight line and covers 32.403 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 Deerfield that is 01342, 01373 (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).
Deerfield is spread out at 159 people per square mile across 32.403 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 2,392 occupied homes in Deerfield, 23% heat with natural gas, 39% with heating oil, 15% with electricity and 15% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2501116670, checked 2026-10-19).
Heating oil is the largest single fuel in Deerfield at 39%, ahead of gas at 23%, 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.
Deerfield has 3 points less oil heat than Franklin County as a whole, where 42% of homes burn oil, and the same 15% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25011, checked 2026-10-19).
Deerfield has 2,481 housing units, 28% built before 1940 and 65% before 1980, with 11% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2501116670, checked 2026-10-19).
Deerfield has 7 points fewer pre-1940 homes than Franklin County as a whole (35%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25011, checked 2026-10-19).
The median Deerfield home was built in 1972 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2501116670, checked 2026-10-19) and the median home has 7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2501116670, checked 2026-10-19).
68% of Deerfield homes are single-family detached, 12% are in two- to four-unit buildings and 11% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2501116670, checked 2026-10-19).
22% of Deerfield homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2501116670, checked 2026-10-19), so beside the 68% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Only 11% of Deerfield homes are new enough to pass the whole-home rebate's weatherization check on age, and 28% date from before 1940, so most of the other 89% show it with a home energy assessment before the heat pump goes in.
Eversource Energy lists Deerfield among the Massachusetts communities it serves for electricity (Eversource Energy communities we serve, https://www.eversource.com/residential/services/communities-we-serve, checked 2026-10-19).
For a Deerfield address billed by Eversource Energy, the Mass Save whole-home heat pump rebate is $2,650 per ton up to $8,500, and the partial-home rebate is $1,125 per ton up to $8,500; for projects installed on or after January 1, 2027, the whole-home figure drops to $2,350 per ton capped at $7,500 (Mass Save air-source heat pump rebates, https://www.masssave.com/residential/rebates-offers-services/heating-and-cooling/heat-pumps/air-source-heat-pumps, checked 2026-10-19).
Median household income in Deerfield is $106,136 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2501116670, checked 2026-10-19); Mass Save's enhanced heat pump incentives are income-based and decided household by household, so the town median only hints at how many neighbors qualify.
Heating design temperature: -3F.

That -3F figure is the Franklin County cold-day number a Deerfield heat pump is sized against, so ask the installer to show the system's heating output at -3F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 39% of the 2,392 occupied Deerfield homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Deerfield home has 7 rooms and was built around 1972, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
