Of the 9,632 occupied homes in Suisun City, 58% heat with natural gas, 0% with heating oil, 38% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0675630, checked 2026-10-19).
Gas heats 58% of Suisun City against electricity at 38%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.

No electric utility is on file for Suisun City 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 Suisun City address before counting it. With 38% of Suisun City homes already on electric heat and 59% 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 Suisun City is $94,787 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0675630, 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), Solano 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 Solano County cold-day number a Suisun City 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 58% of Suisun City 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 Suisun City home has 5.7 rooms and was built around 1984, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
