Median household income in La Marque is $71,102 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4841116, 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: 34F.

That 34F figure is the Galveston County cold-day number a La Marque heat pump is sized against, so ask the installer to show the system's heating output at 34F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median La Marque home has 5.6 rooms and was built around 1977, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
