San Francisco / Piedmont
Piedmont has 10,945 residents (give or take 33) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0656938, checked 2026-10-19), about 6,438 people per square mile.
Piedmont is about 44 miles from the Census center point for San Francisco in a straight line and covers 1.7 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).
6,438 people per square mile puts Piedmont in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 3,864 occupied homes in Piedmont, 89% heat with natural gas, 0% with heating oil, 10% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0656938, checked 2026-10-19).
Gas heats 89% of Piedmont against electricity at 10%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Piedmont has about the Alameda County oil share of 0% and 20 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).
Piedmont has 4,073 housing units, 63% built before 1940 and 96% before 1980, with 1% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0656938, checked 2026-10-19).
Piedmont has 43 points more pre-1940 homes than Alameda County as a whole (20%) and 14 points fewer 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). An older stock means more insulation upgrades before the heat pump goes in.
The median Piedmont home was built in 1938 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0656938, checked 2026-10-19) and the median home has 8.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0656938, checked 2026-10-19).
95% of Piedmont homes are single-family detached, 2% are in two- to four-unit buildings and 1% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0656938, checked 2026-10-19).
With 95% detached houses and 2% in small multi-family buildings, a Piedmont quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 9% of Piedmont homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0656938, checked 2026-10-19), the landlord signs the quote in many of them.
Piedmont has 44 points more detached houses than Alameda County overall (51%) and 28 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).
Only 9% of Piedmont homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0656938, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
63% of Piedmont homes were built before 1940 and 96% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0656938, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
No electric utility is on file for Piedmont 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 Piedmont address before counting it. With 10% of Piedmont homes already on electric heat and 89% 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 Piedmont is $250,001 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0656938, 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 Piedmont 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 89% of Piedmont on gas and 10% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Piedmont house from before 1940 (63% of the 4,073 units) rarely matches a square-footage rule of thumb.
