The Indianapolis market
Current Indianapolis permit rules for replacing a water heater, furnace, AC or heat pump were not confirmed from official sources for this page, including the fee, who may file and whether an inspection follows. Contact the city's Department of Business and Neighborhood Services before work starts; Carmel, Fishers and other suburbs issue their own permits. DOE's Building America guide puts Marion County in cold climate zone 5A, so heating dominates. EIA's 2020 survey found 82% of Indiana homes heat with a furnace, 65% use natural gas and 81% have central air. Indiana is one of the few states whose federally funded rebates are open: the Indiana Energy Saver Program covers heat pump water heaters and heat pump HVAC for households under 150% of area median income.
Gas heats water in 52% of Indiana homes and electricity in 43%. For an income-eligible household, a heat pump water heater can change the math against a standard electric tank. It needs open space around it and a drain for condensate, so ask whether your basement or utility room fits one. Ask the installer which permit they file. For a gas tank, ask whether the vent connector and gas shutoff are being replaced.
