No electric utility is on file for Edwardsville on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Ameren Illinois Instant Incentives (ducted ASHP), run by Ameren Illinois, is a live program for Illinois addresses and lists a standard figure of $900 (registry row 45 verified 2026-10-15, https://amerenillinoissavings.com/residential/ducted-air-source-heat-pump/, checked 2026-10-16); confirm eligibility for the Edwardsville address before counting it. With 39% of Edwardsville homes already on electric heat and 60% 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 Edwardsville is $86,721 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1722697, 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.

That 2F figure is the Madison County cold-day number a Edwardsville heat pump is sized against, so ask the installer to show the system's heating output at 2F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 59% of Edwardsville on gas and 39% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Edwardsville home has 6.2 rooms and was built around 1986, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
