San Francisco / Newark
Newark has 46,903 residents (give or take 42) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0650916, checked 2026-10-19), about 3,370 people per square mile.
Newark is about 57 miles from the Census center point for San Francisco in a straight line and covers 13.919 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 Newark that is 94560 (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).
3,370 people per square mile puts Newark in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 15,252 occupied homes in Newark, 68% heat with natural gas, 0% with heating oil, 27% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0650916, checked 2026-10-19).
Gas heats 68% of Newark against electricity at 27%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Newark has about the Alameda County oil share of 0% and 3 points less electric heat than the county's 30% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06001, checked 2026-10-19).
Newark has 16,015 housing units, 3% built before 1940 and 59% before 1980, with 18% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0650916, checked 2026-10-19).
Newark has 17 points fewer pre-1940 homes than Alameda County as a whole (20%) and 3 points more homes built after 2000 than the county's 15% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06001, checked 2026-10-19).
The median Newark home was built in 1975 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0650916, checked 2026-10-19) and the median home has 5.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0650916, checked 2026-10-19).
68% of Newark homes are single-family detached, 5% are in two- to four-unit buildings and 14% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0650916, checked 2026-10-19).
31% of Newark homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0650916, checked 2026-10-19), so beside the 68% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Newark has 17 points more detached houses than Alameda County overall (51%) and 15 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=050XX00US06001, checked 2026-10-19).
No electric utility is on file for Newark 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 Newark address before counting it. With 27% of Newark homes already on electric heat and 70% 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 Newark is $169,064 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0650916, 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: 27F.

That 27F figure is the Alameda County cold-day number a Newark 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 68% of Newark on gas and 27% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Newark home has 5.2 rooms and was built around 1975, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
