San Francisco / San Francisco
San Francisco has 830,235 residents (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0667000, checked 2026-10-19), about 17,784 people per square mile.
San Francisco is the city this door is named for; it covers 46.685 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 San Francisco that is 94102, 94103, 94104, 94105, 94107, 94108, 94109, 94110 and 20 more (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 San Francisco is $140,970 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0667000, 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.
At 17,784 people per square mile, San Francisco is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
18% of San Francisco homes are single-family detached, 20% are in two- to four-unit buildings and 49% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0667000, checked 2026-10-19).
With 49% of San Francisco homes in buildings of five or more units and 18% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 62% of San Francisco homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0667000, checked 2026-10-19), the landlord signs the quote in many of them.
With 62% of San Francisco homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0667000, 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 363,970 occupied homes in San Francisco, 55% heat with natural gas, 0% with heating oil, 36% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0667000, checked 2026-10-19).
Gas heats 55% of San Francisco against electricity at 36%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
San Francisco has about the San Francisco County oil share of 0% and the same 36% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06075, checked 2026-10-19).
No electric utility is on file for San Francisco on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
LADWP Consumer Rebate Program heat pump HVAC, run by LADWP, is a live program for California addresses and publishes its terms without one headline figure (registry row 24 verified 2026-10-14, https://www.ladwp.com/residential-services/assistance-programs/consumer-rebate-program, checked 2026-10-16); confirm eligibility for the San Francisco address before counting it. With 36% of San Francisco homes already on electric heat and 57% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
San Francisco has 414,602 housing units, 45% built before 1940 and 76% before 1980, with 14% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0667000, checked 2026-10-19).
San Francisco tracks San Francisco County on housing age, with the county at 45% pre-1940 and 14% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06075, checked 2026-10-19).
The median San Francisco home was built in 1946 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0667000, checked 2026-10-19) and the median home has 4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0667000, checked 2026-10-19).
45% of San Francisco homes were built before 1940 and 76% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0667000, 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.
Heating design temperature: 32F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), San Francisco County row, 99% heating, PDF pages 11 to 13 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 32F figure is the San Francisco County cold-day number a San Francisco heat pump is sized against, so ask the installer to show the system's heating output at 32F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 55% of San Francisco on gas and 36% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a San Francisco house from before 1940 (45% of the 414,602 units) rarely matches a square-footage rule of thumb.
