Los Angeles / Alhambra
Alhambra has 81,022 residents (give or take 126) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0600884, checked 2026-10-19), about 10,617 people per square mile.
Alhambra is about 16 miles from the Census center point for Los Angeles in a straight line and covers 7.631 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 Alhambra that is 91801, 91803 (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 Alhambra is $88,024 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0600884, 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.
At 10,617 people per square mile, Alhambra is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
41% of Alhambra homes are single-family detached, 13% are in two- to four-unit buildings and 34% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0600884, checked 2026-10-19).
59% of Alhambra homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0600884, checked 2026-10-19), so beside the 41% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Alhambra has 6 points fewer detached houses than Los Angeles County overall (47%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US06037, checked 2026-10-19).
59% of Alhambra homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0600884, 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 30,425 occupied homes in Alhambra, 56% heat with natural gas, 0% with heating oil, 38% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0600884, checked 2026-10-19).
Gas heats 56% of Alhambra against electricity at 38%, 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.
Alhambra has about the Los Angeles County oil share of 0% and 9 points more 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).
No electric utility is on file for Alhambra 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 Alhambra address before counting it. With 38% of Alhambra homes already on electric heat and 58% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Alhambra has 32,751 housing units, 23% built before 1940 and 72% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0600884, checked 2026-10-19).
Alhambra has 9 points more pre-1940 homes than Los Angeles County as a whole (14%) and 5 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.
The median Alhambra home was built in 1960 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0600884, checked 2026-10-19) and the median home has 4.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0600884, checked 2026-10-19).
72% of Alhambra homes were built before 1980 and only 7% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0600884, 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.
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 Alhambra 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 56% of Alhambra on gas and 38% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Alhambra home has 4.3 rooms and was built around 1960, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
