San Francisco / Pacifica
Pacifica has 37,261 residents (give or take 56) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0654806, checked 2026-10-19), about 2,961 people per square mile.
Pacifica is about 31 miles from the Census center point for San Francisco in a straight line and covers 12.583 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 Pacifica that is 94044 (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).
Of the 13,915 occupied homes in Pacifica, 74% heat with natural gas, 0% with heating oil, 23% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0654806, checked 2026-10-19).
Gas heats 74% of Pacifica against electricity at 23%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Pacifica has about the San Mateo County oil share of 0% and 9 points less electric heat than the county's 32% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06081, checked 2026-10-19).
Pacifica has 14,665 housing units, 3% built before 1940 and 82% before 1980, with 5% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0654806, checked 2026-10-19).
Pacifica has 6 points fewer pre-1940 homes than San Mateo County as a whole (9%) and 7 points fewer homes built after 2000 than the county's 12% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06081, checked 2026-10-19).
The median Pacifica home was built in 1966 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0654806, 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=160XX00US0654806, checked 2026-10-19).
72% of Pacifica homes are single-family detached, 5% are in two- to four-unit buildings and 15% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0654806, checked 2026-10-19).
With 72% detached houses and 5% in small multi-family buildings, a Pacifica quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 32% of Pacifica homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0654806, checked 2026-10-19), the landlord signs the quote in many of them.
Pacifica has 17 points more detached houses than San Mateo County overall (55%) and 14 points fewer five-plus-unit buildings than the county's 29% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US06081, checked 2026-10-19).
82% of Pacifica homes were built before 1980 and only 5% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0654806, 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.
No electric utility is on file for Pacifica 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 Pacifica address before counting it. With 23% of Pacifica homes already on electric heat and 75% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Pacifica is $160,523 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0654806, 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: 29F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), San Mateo 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 29F figure is the San Mateo County cold-day number a Pacifica heat pump is sized against, so ask the installer to show the system's heating output at 29F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 74% of Pacifica on gas and 23% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Pacifica home has 5.4 rooms and was built around 1966, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
