San Francisco / Santa Clara
Santa Clara has 130,256 residents (give or take 69) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0669084, checked 2026-10-19), about 7,127 people per square mile.
Santa Clara is about 63 miles from the Census center point for San Francisco in a straight line and covers 18.277 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 Santa Clara that is 95050, 95051, 95053, 95054 (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 Santa Clara is $178,958 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0669084, 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.
7,127 people per square mile puts Santa Clara in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
37% of Santa Clara homes are single-family detached, 7% are in two- to four-unit buildings and 45% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0669084, checked 2026-10-19).
With 45% of Santa Clara homes in buildings of five or more units and 37% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 59% of Santa Clara homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0669084, checked 2026-10-19), the landlord signs the quote in many of them.
Santa Clara has 14 points fewer detached houses than Santa Clara County overall (51%) and 16 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).
59% of Santa Clara homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0669084, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
Of the 50,088 occupied homes in Santa Clara, 53% heat with natural gas, 0% with heating oil, 43% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0669084, checked 2026-10-19).
Gas heats 53% of Santa Clara against electricity at 43%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Santa Clara has about the Santa Clara County oil share of 0% and 7 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 Santa Clara on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Santa Clara has 53,021 housing units, 4% built before 1940 and 59% before 1980, with 27% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0669084, checked 2026-10-19).
Santa Clara has 7 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 Santa Clara home was built in 1974 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0669084, checked 2026-10-19) and the median home has 4.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0669084, checked 2026-10-19).
Heating design temperature: 27F.

That 27F figure is the Santa Clara County cold-day number a Santa Clara 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 whether the quote is whole-home or partial-home, because with 53% of Santa Clara on gas and 43% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Santa Clara home has 4.1 rooms and was built around 1974, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
