Grand Rapids / Port Huron
Port Huron has 28,620 residents (give or take 81) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2665820, checked 2026-10-19), about 3,532 people per square mile.
Port Huron is about 163 miles from the Census center point for Grand Rapids in a straight line and covers 8.102 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 Port Huron that is 48060 (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).
3,532 people per square mile puts Port Huron in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 12,734 occupied homes in Port Huron, 87% heat with natural gas, 0% with heating oil, 9% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2665820, checked 2026-10-19).
Gas heats 87% of Port Huron against electricity at 9%, 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.
Port Huron has about the St. Clair County oil share of 1% and the same 9% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US26147, checked 2026-10-19).
Port Huron has 13,729 housing units, 33% built before 1940 and 79% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2665820, checked 2026-10-19).
Port Huron has 16 points more pre-1940 homes than St. Clair County as a whole (17%) and 10 points fewer homes built after 2000 than the county's 17% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US26147, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Port Huron home was built in 1955 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2665820, 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=160XX00US2665820, checked 2026-10-19).
70% of Port Huron homes are single-family detached, 13% are in two- to four-unit buildings and 13% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2665820, checked 2026-10-19).
With 70% detached houses and 13% in small multi-family buildings, a Port Huron quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 38% of Port Huron homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2665820, checked 2026-10-19), the landlord signs the quote in many of them.
Port Huron has 9 points fewer detached houses than St. Clair County overall (79%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US26147, checked 2026-10-19).
33% of Port Huron homes were built before 1940 and 79% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2665820, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
No electric utility is on file for Port Huron 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 Port Huron address before counting it. With 9% of Port Huron homes already on electric heat and 89% 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 Port Huron address before counting it.
Median household income in Port Huron is $50,366 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2665820, 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. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), St. Clair County row, 99% heating, PDF pages 56 to 60 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 4F figure is the St. Clair County cold-day number a Port Huron 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 87% of Port Huron on gas and 9% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Port Huron house from before 1940 (33% of the 13,729 units) rarely matches a square-footage rule of thumb.
