Los Angeles / Sierra Madre
Sierra Madre is about 23 miles from the Census center point for Los Angeles in a straight line and covers 2.951 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).
Sierra Madre has 10,940 residents (give or take 25) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0671806, checked 2026-10-19), about 3,707 people per square mile.
The quote form takes a ZIP code; for Sierra Madre that is 91024 (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).
3,707 people per square mile puts Sierra Madre in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 4,620 occupied homes in Sierra Madre, 73% heat with natural gas, 0% with heating oil, 23% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0671806, checked 2026-10-19).
Sierra Madre has about the Los Angeles County oil share of 0% and 6 points less electric heat than the county's 29% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06037, checked 2026-10-19).
Gas heats 73% of Sierra Madre against electricity at 23%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
The median Sierra Madre home was built in 1959 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0671806, 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=160XX00US0671806, checked 2026-10-19).
Sierra Madre has 4,977 housing units, 18% built before 1940 and 80% before 1980, with 6% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0671806, checked 2026-10-19).
Sierra Madre has 4 points more pre-1940 homes than Los Angeles County as a whole (14%) and 6 points fewer homes built after 2000 than the county's 12% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06037, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
80% of Sierra Madre homes were built before 1980 and only 6% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0671806, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
60% of Sierra Madre homes are single-family detached, 7% are in two- to four-unit buildings and 21% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0671806, checked 2026-10-19).
44% of Sierra Madre homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0671806, checked 2026-10-19), so beside the 60% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Sierra Madre has 13 points more detached houses than Los Angeles County overall (47%) and 15 points fewer five-plus-unit buildings than the county's 36% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US06037, checked 2026-10-19).
44% of Sierra Madre homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0671806, 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.
No electric utility is on file for Sierra Madre 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 Sierra Madre address before counting it. With 23% of Sierra Madre homes already on electric heat and 74% 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 Sierra Madre is $143,547 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0671806, 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: 14F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Los Angeles 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 14F figure is the Los Angeles County cold-day number a Sierra Madre heat pump is sized against, so ask the installer to show the system's heating output at 14F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 73% of Sierra Madre on gas and 23% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Sierra Madre home has 5.2 rooms and was built around 1959, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
