San Francisco / Stanford
Stanford has 18,662 residents (give or take 967) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0673906, checked 2026-10-19), about 6,786 people per square mile.
Stanford is about 52 miles from the Census center point for San Francisco in a straight line and covers 2.75 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 Stanford that is 94305 (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).
Median household income in Stanford is $75,208 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0673906, 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.
6,786 people per square mile puts Stanford in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
22% of Stanford homes are single-family detached, 8% are in two- to four-unit buildings and 65% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0673906, checked 2026-10-19).
With 65% of Stanford homes in buildings of five or more units and 22% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 73% of Stanford homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0673906, checked 2026-10-19), the landlord signs the quote in many of them.
Stanford has 29 points fewer detached houses than Santa Clara County overall (51%) and 36 points more five-plus-unit buildings than the county's 29% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US06085, checked 2026-10-19).
With 73% of Stanford homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0673906, checked 2026-10-19), most heat pump quotes here are landlord-driven: the landlord signs the contract and picks the equipment, and the tenant sees the lower bill.
Of the 3,428 occupied homes in Stanford, 36% heat with natural gas, 0% with heating oil, 55% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0673906, checked 2026-10-19).
Electricity already heats 55% of Stanford homes, ahead of gas at 36%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Stanford has about the Santa Clara County oil share of 0% and 19 points more electric heat than the county's 36% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06085, checked 2026-10-19).
No electric utility is on file for Stanford on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Stanford has 4,186 housing units, 5% built before 1940 and 47% before 1980, with 28% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0673906, checked 2026-10-19).
Stanford has 8 points more homes built after 2000 than the county's 20% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06085, checked 2026-10-19).
The median Stanford home was built in 1982 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0673906, checked 2026-10-19) and the median home has 3.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0673906, checked 2026-10-19).

That 27F figure is the Santa Clara County cold-day number a Stanford heat pump is sized against, so ask the installer to show the system's heating output at 27F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Stanford home has 3.4 rooms and was built around 1982, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
