Los Angeles / La Palma
La Palma has 15,272 residents (give or take 55) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0640256, checked 2026-10-19), about 8,575 people per square mile.
La Palma is about 24 miles from the Census center point for Los Angeles in a straight line and covers 1.781 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 La Palma that is 90623 (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).
At 8,575 people per square mile, La Palma is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
Of the 5,118 occupied homes in La Palma, 67% heat with natural gas, 0% with heating oil, 29% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0640256, checked 2026-10-19).
Gas heats 67% of La Palma against electricity at 29%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
La Palma has about the Orange County oil share of 0% and 2 points more electric heat than the county's 27% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06059, checked 2026-10-19).
La Palma has 5,206 housing units, 1% built before 1940 and 81% before 1980, with 8% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0640256, checked 2026-10-19).
La Palma has 10 points fewer homes built after 2000 than the county's 18% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06059, checked 2026-10-19).
The median La Palma home was built in 1972 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0640256, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0640256, checked 2026-10-19).
66% of La Palma homes are single-family detached, 4% 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=160XX00US0640256, checked 2026-10-19).
32% of La Palma homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0640256, checked 2026-10-19), so beside the 66% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
La Palma has 17 points more detached houses than Orange County overall (49%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US06059, checked 2026-10-19).
81% of La Palma homes were built before 1980 and only 8% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0640256, 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.
No electric utility is on file for La Palma 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 La Palma address before counting it. With 29% of La Palma homes already on electric heat and 68% 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 La Palma is $117,989 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0640256, 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: 29F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Orange 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 29F figure is the Orange County cold-day number a La Palma heat pump is sized against, so ask the installer to show the system's heating output at 29F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 67% of La Palma on gas and 29% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median La Palma home has 5.9 rooms and was built around 1972, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
