Detroit / Royal Oak
Royal Oak has 57,950 residents (give or take 32) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2670040, checked 2026-10-19), about 4,914 people per square mile.
Royal Oak is about 9 miles from the Census center point for Detroit in a straight line and covers 11.792 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 Royal Oak that is 48067, 48073 (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).
4,914 people per square mile puts Royal Oak in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 29,110 occupied homes in Royal Oak, 83% heat with natural gas, 0% with heating oil, 14% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2670040, checked 2026-10-19).
Gas heats 83% of Royal Oak against electricity at 14%, 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.
Royal Oak has about the Oakland County oil share of 0% and 3 points more electric heat than the county's 11% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US26125, checked 2026-10-19).
Royal Oak has 31,130 housing units, 17% built before 1940 and 82% before 1980, with 10% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2670040, checked 2026-10-19).
Royal Oak has 10 points more pre-1940 homes than Oakland County as a whole (7%) and 6 points fewer homes built after 2000 than the county's 16% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US26125, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Royal Oak home was built in 1956 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2670040, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2670040, checked 2026-10-19).
65% of Royal Oak homes are single-family detached, 6% are in two- to four-unit buildings and 23% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2670040, checked 2026-10-19).
32% of Royal Oak homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2670040, checked 2026-10-19), so beside the 65% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
82% of Royal Oak homes were built before 1980 and only 10% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2670040, 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 Royal Oak 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 Royal Oak address before counting it. With 14% of Royal Oak homes already on electric heat and 84% 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 Royal Oak address before counting it.
Median household income in Royal Oak is $101,109 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2670040, 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: 4F.

That 4F figure is the Oakland County cold-day number a Royal Oak heat pump is sized against, so ask the installer to show the system's heating output at 4F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 83% of Royal Oak on gas and 14% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Royal Oak home has 5.5 rooms and was built around 1956, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
