Grand Rapids / Charlotte
Charlotte has 9,277 residents (give or take 22) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2614820, checked 2026-10-19), about 1,438 people per square mile.
Charlotte is about 50 miles from the Census center point for Grand Rapids in a straight line and covers 6.451 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).
Of the 3,625 occupied homes in Charlotte, 79% heat with natural gas, 0% with heating oil, 19% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2614820, checked 2026-10-19).
Gas heats 79% of Charlotte against electricity at 19%, 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.
Charlotte has about the Eaton County oil share of 2% and 4 points more electric heat than the county's 15% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US26045, checked 2026-10-19).
Charlotte has 3,857 housing units, 29% built before 1940 and 67% before 1980, with 15% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2614820, checked 2026-10-19).
Charlotte has 14 points more pre-1940 homes than Eaton County as a whole (15%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US26045, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Charlotte home was built in 1964 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2614820, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2614820, checked 2026-10-19).
61% of Charlotte homes are single-family detached, 9% are in two- to four-unit buildings and 19% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2614820, checked 2026-10-19).
33% of Charlotte homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2614820, checked 2026-10-19), so beside the 61% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Charlotte has 9 points fewer detached houses than Eaton County overall (70%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US26045, checked 2026-10-19).
67% of Charlotte homes were built before 1980 and only 15% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2614820, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Charlotte on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
DTE Energy heating and cooling rebates (southeast Michigan only), run by DTE Energy, is a live program for Michigan addresses and covers qualifying equipment at $1,500 per system (registry row 19 verified 2026-10-15, https://www.dteenergy.com/us/en/residential/save-money-energy/rebates-and-offers/air-conditioners.html, checked 2026-10-16); confirm eligibility for the Charlotte address before counting it. With 19% of Charlotte homes already on electric heat and 80% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Consumers Energy Home Solutions 2026 (ASHP), run by Consumers Energy, is a live program for Michigan addresses and lists a standard figure of $300 (registry row 50 verified 2026-10-15, https://www.consumersenergy.com/residential/savings-and-clean-energy/rebates/heating-and-cooling, checked 2026-10-16); confirm eligibility for the Charlotte address before counting it.
Median household income in Charlotte is $62,681 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2614820, 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: 3F.

That 3F figure is the Eaton County cold-day number a Charlotte 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 whether the quote is whole-home or partial-home, because with 79% of Charlotte on gas and 19% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Charlotte home has 5.8 rooms and was built around 1964, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
