San Francisco / Dublin
Dublin has 70,803 residents (give or take 52) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0620018, checked 2026-10-19), about 4,649 people per square mile.
Dublin is about 62 miles from the Census center point for San Francisco in a straight line and covers 15.229 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 Dublin that is 94568 (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).
4,649 people per square mile puts Dublin in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 24,165 occupied homes in Dublin, 65% heat with natural gas, 0% with heating oil, 32% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0620018, checked 2026-10-19).
Gas heats 65% of Dublin against electricity at 32%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Dublin has about the Alameda County oil share of 0% and 2 points more 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).
Dublin has 25,157 housing units, 0% built before 1940 and 19% before 1980, with 60% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0620018, checked 2026-10-19).
Dublin has 20 points fewer pre-1940 homes than Alameda County as a whole (20%) and 45 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 Dublin home was built in 2004 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0620018, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0620018, checked 2026-10-19).
54% of Dublin homes are single-family detached, 2% are in two- to four-unit buildings and 27% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0620018, checked 2026-10-19).
34% of Dublin homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0620018, checked 2026-10-19), so beside the 54% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
60% of Dublin housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0620018, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
No electric utility is on file for Dublin 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 Dublin address before counting it. With 32% of Dublin homes already on electric heat and 66% 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 Dublin is $214,385 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0620018, 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. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Alameda 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 27F figure is the Alameda County cold-day number a Dublin 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 65% of Dublin on gas and 32% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Dublin home has 5.6 rooms and was built around 2004, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
