Of the 6,429 occupied homes in Havre de Grace, 53% heat with natural gas, 5% with heating oil, 39% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2437600, checked 2026-10-19).
Gas heats 53% of Havre de Grace against electricity at 39%, 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.
Havre de Grace has 5 points less oil heat than Harford County as a whole, where 10% of homes burn oil, and 3 points less electric heat than the county's 42% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US24025, checked 2026-10-19).
Havre de Grace has 6,660 housing units, 11% built before 1940 and 39% before 1980, with 34% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2437600, checked 2026-10-19).
Havre de Grace has 7 points more pre-1940 homes than Harford County as a whole (4%) and 9 points more homes built after 2000 than the county's 25% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US24025, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Havre de Grace home was built in 1992 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2437600, 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=160XX00US2437600, checked 2026-10-19).
54% of Havre de Grace homes are single-family detached, 10% are in two- to four-unit buildings and 16% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2437600, checked 2026-10-19).
28% of Havre de Grace homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2437600, checked 2026-10-19), so beside the 54% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Havre de Grace has 6 points fewer detached houses than Harford County overall (60%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US24025, checked 2026-10-19).
No electric utility is on file for Havre de Grace 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 Havre de Grace is $105,817 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2437600, 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.

That 8F figure is the Harford County cold-day number a Havre de Grace 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 53% of Havre de Grace on gas and 39% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Havre de Grace home has 6.6 rooms and was built around 1992, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
