San Ramon has 85,993 residents (give or take 114) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0668378, checked 2026-10-19), about 4,287 people per square mile.
San Ramon is about 60 miles from the Census center point for San Francisco in a straight line and covers 20.059 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 Ramon that is 94582, 94583 (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).
4,287 people per square mile puts San Ramon in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 30,103 occupied homes in San Ramon, 68% heat with natural gas, 0% with heating oil, 28% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0668378, checked 2026-10-19).
Gas heats 68% of San Ramon against electricity at 28%, 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 Ramon has about the Contra Costa County oil share of 0% and the same 28% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06013, checked 2026-10-19).
San Ramon has 30,744 housing units, 0% built before 1940 and 24% before 1980, with 39% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0668378, checked 2026-10-19).
San Ramon has 4 points fewer pre-1940 homes than Contra Costa County as a whole (4%) and 20 points more homes built after 2000 than the county's 19% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06013, checked 2026-10-19).
The median San Ramon home was built in 1994 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0668378, checked 2026-10-19) and the median home has 6.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0668378, checked 2026-10-19).
63% of San Ramon homes are single-family detached, 4% are in two- to four-unit buildings and 19% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0668378, checked 2026-10-19).
29% of San Ramon homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0668378, checked 2026-10-19), so beside the 63% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
No electric utility is on file for San Ramon 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 Ramon address before counting it. With 28% of San Ramon homes already on electric heat and 69% 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 San Ramon is $196,161 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0668378, 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), Contra Costa 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 Contra Costa County cold-day number a San Ramon 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 San Ramon on gas and 28% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median San Ramon home has 6.1 rooms and was built around 1994, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
