Salt Lake City / Coalville
Coalville has 1,881 residents (give or take 376) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4914840, checked 2026-10-19), about 305 people per square mile.
Coalville is about 28 miles from the Census center point for Salt Lake City in a straight line and covers 6.172 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 583 occupied homes in Coalville, 88% heat with natural gas, 0% with heating oil, 10% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4914840, checked 2026-10-19).
Gas heats 88% of Coalville against electricity at 10%, 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.
Coalville has about the Summit County oil share of 0% and the same 10% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US49043, checked 2026-10-19).
Coalville has 613 housing units, 11% built before 1940 and 48% before 1980, with 32% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4914840, checked 2026-10-19).
Coalville has 8 points more pre-1940 homes than Summit County as a whole (3%) and 7 points fewer homes built after 2000 than the county's 39% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US49043, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Coalville home was built in 1983 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4914840, checked 2026-10-19) and the median home has 5.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4914840, checked 2026-10-19).
69% of Coalville homes are single-family detached, 11% are in two- to four-unit buildings and 2% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4914840, checked 2026-10-19).
36% of Coalville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4914840, checked 2026-10-19), so beside the 69% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Coalville has 6 points more detached houses than Summit County overall (63%) and 16 points fewer five-plus-unit buildings than the county's 18% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US49043, checked 2026-10-19).
No electric utility is on file for Coalville 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 Coalville is $95,729 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4914840, 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 Summit County cold-day number a Coalville 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 88% of Coalville on gas and 10% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Coalville home has 5.4 rooms and was built around 1983, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
