Salt Lake City / Millcreek
Millcreek is about 8 miles from the Census center point for Salt Lake City in a straight line and covers 12.895 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).
Millcreek has 63,648 residents (give or take 69) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4950150, checked 2026-10-19), about 4,936 people per square mile.
The quote form takes a ZIP code; for Millcreek that is 84106, 84124 (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).
4,936 people per square mile puts Millcreek in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 25,920 occupied homes in Millcreek, 86% heat with natural gas, 0% with heating oil, 13% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4950150, checked 2026-10-19).
Millcreek has about the Salt Lake County oil share of 0% and 3 points less electric heat than the county's 16% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US49035, checked 2026-10-19).
Gas heats 86% of Millcreek against electricity at 13%, 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.
The median Millcreek home was built in 1973 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4950150, checked 2026-10-19) and the median home has 5.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4950150, checked 2026-10-19).
Millcreek has 28,104 housing units, 3% built before 1940 and 62% before 1980, with 17% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4950150, checked 2026-10-19).
Millcreek has 4 points fewer pre-1940 homes than Salt Lake County as a whole (7%) and 15 points fewer homes built after 2000 than the county's 32% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US49035, checked 2026-10-19).
62% of Millcreek homes were built before 1980 and only 17% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4950150, 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.
54% of Millcreek homes are single-family detached, 7% are in two- to four-unit buildings and 29% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4950150, checked 2026-10-19).
39% of Millcreek homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4950150, 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.
Millcreek has 6 points fewer detached houses than Salt Lake County overall (60%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US49035, checked 2026-10-19).
No electric utility is on file for Millcreek 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 Millcreek is $98,045 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4950150, 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: 11F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Salt Lake County row, 99% heating, PDF pages 125 to 127 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 11F figure is the Salt Lake County cold-day number a Millcreek heat pump is sized against, so ask the installer to show the system's heating output at 11F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 86% of Millcreek on gas and 13% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Millcreek home has 5.7 rooms and was built around 1973, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
