Median household income in Casa Grande is $69,983 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0410530, 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 25F figure is the Pinal County cold-day number a Casa Grande heat pump is sized against, so ask the installer to show the system's heating output at 25F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Casa Grande home has 5.3 rooms and was built around 2003, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
