The quote form takes a ZIP code; for Shrewsbury that is 17361 (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).
Of the 1,728 occupied homes in Shrewsbury, 70% heat with natural gas, 6% with heating oil, 22% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4270568, checked 2026-10-19).
Gas heats 70% of Shrewsbury against electricity at 22%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Shrewsbury has 7 points less oil heat than York County as a whole, where 13% of homes burn oil, and 2 points less electric heat than the county's 24% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42133, checked 2026-10-19).
Shrewsbury has 1,772 housing units, 9% built before 1940 and 38% before 1980, with 27% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4270568, checked 2026-10-19).
Shrewsbury has 9 points fewer pre-1940 homes than York County as a whole (18%) and 6 points more homes built after 2000 than the county's 21% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42133, checked 2026-10-19).
The median Shrewsbury home was built in 1986 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4270568, checked 2026-10-19) and the median home has 7.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4270568, checked 2026-10-19).
77% of Shrewsbury homes are single-family detached, 3% 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=160XX00US4270568, checked 2026-10-19).
With 77% detached houses and 3% in small multi-family buildings, a Shrewsbury quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 20% of Shrewsbury homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4270568, checked 2026-10-19), the landlord signs the quote in many of them.
Shrewsbury has 13 points more detached houses than York County overall (64%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42133, checked 2026-10-19).
No electric utility is on file for Shrewsbury on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Shrewsbury is $101,833 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4270568, 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.
Heating design temperature: 8F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), York County row, 99% heating, PDF pages 102 to 105 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 8F figure is the York County cold-day number a Shrewsbury heat pump is sized against, so ask the installer to show the system's heating output at 8F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 70% of Shrewsbury on gas and 22% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Shrewsbury home has 7.3 rooms and was built around 1986, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
