San Francisco / Rohnert Park
Rohnert Park has 44,575 residents (give or take 57) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0662546, checked 2026-10-19), about 6,118 people per square mile.
Rohnert Park is about 47 miles from the Census center point for San Francisco in a straight line and covers 7.286 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 Rohnert Park that is 94928 (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 Rohnert Park is $99,273 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0662546, 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.
6,118 people per square mile puts Rohnert Park in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
46% of Rohnert Park homes are single-family detached, 9% are in two- to four-unit buildings and 29% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0662546, checked 2026-10-19).
50% of Rohnert Park homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0662546, checked 2026-10-19), so beside the 46% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Rohnert Park has 21 points fewer detached houses than Sonoma County overall (67%) and 16 points more five-plus-unit buildings than the county's 13% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US06097, checked 2026-10-19).
50% of Rohnert Park homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0662546, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
Of the 17,181 occupied homes in Rohnert Park, 61% heat with natural gas, 0% with heating oil, 35% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0662546, checked 2026-10-19).
Gas heats 61% of Rohnert Park against electricity at 35%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Rohnert Park has about the Sonoma County oil share of 0% and 9 points more electric heat than the county's 26% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06097, checked 2026-10-19).
No electric utility is on file for Rohnert Park 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 Rohnert Park address before counting it. With 35% of Rohnert Park homes already on electric heat and 61% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Rohnert Park has 17,807 housing units, 1% built before 1940 and 43% before 1980, with 15% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0662546, checked 2026-10-19).
Rohnert Park has 7 points fewer pre-1940 homes than Sonoma County as a whole (8%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06097, checked 2026-10-19).
The median Rohnert Park home was built in 1982 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0662546, checked 2026-10-19) and the median home has 4.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0662546, checked 2026-10-19).
Heating design temperature: 26F.

That 26F figure is the Sonoma County cold-day number a Rohnert Park heat pump is sized against, so ask the installer to show the system's heating output at 26F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 61% of Rohnert Park on gas and 35% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Rohnert Park home has 4.8 rooms and was built around 1982, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
