Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. In Indianapolis cold snaps, call right away if freezing weather is forecast — a home without heat risks frozen pipes. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Pipes freezing while heat is out
If you will be away during cold weather, the American Red Cross advises leaving the heat on and set no lower than 55°F (Red Cross). If your Indianapolis home’s heat has failed and freezing weather is forecast, call for service right away.
AC out during a summer heat wave
Outdoor unit silent · warm air at vents · short-cycling. An AC failure in Indianapolis summer heat is worth a same-day call. Electrical and refrigerant faults need a technician to diagnose.

HVAC in Indianapolis, IN: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Indiana licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Indianapolis International Airport (KIND) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00093819), Indianapolis records an annual mean temperature of 53.6°F, approximately 5,250.3 annual heating degree days against 1,139.1 cooling degree days, 43.63 inches of annual precipitation, and 25.5 inches of annual snowfall. The 4.6:1 HDD-to-CDD ratio defines Indianapolis as a heating-dominated Zone 5A cool-humid climate — similar in magnitude to Columbus but with slightly lower annual snowfall and marginally higher cooling demand.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Indianapolis city (balance), Indiana) report 359,665 occupied housing units with a median year built of 1972. Heating-fuel distribution: 56.7% utility natural gas (203,861 units), 40.6% electricity (146,128 units), and 5,868 bottled/LP gas homes. Because Indianapolis is a consolidated city-county (Indianapolis-Marion under Unigov), the ACS entity is reported as “Indianapolis city (balance)” — representing the portion of Marion County served by the consolidated city government.
Indianapolis’s 5,250 HDD puts it in a climate where dual-fuel (hybrid) heat pump systems make sense. ENERGY STAR describes a dual-fuel system — a heat pump paired with a gas or oil furnace — as one that “enables you to use each system optimally based on costs and environmental benefits.” When outdoor temperatures drop below the heat pump’s balance point, the companion gas furnace takes over. For Indianapolis homeowners replacing an aging gas furnace, a dual-fuel specification — heat pump outdoor unit + gas furnace indoor coil — captures heat-pump efficiency during milder months while preserving gas backup for the coldest nights.
Indiana Licensing Authority
Indiana does not issue a statewide HVAC contractor license through the Indiana Professional Licensing Agency. Instead, HVAC contractor registration and permitting in Indianapolis are handled locally through the Indianapolis Department of Business & Neighborhood Services (DBNS). For Indianapolis homeowners, verifying that a contractor is registered with DBNS before authorizing any HVAC work is the critical due-diligence step — more important than in states with a statewide board, because the local registration is the only formal credential. Contact DBNS directly for the current mechanical permit fee schedule and to verify contractor status. Primary source: DSIRE — Indiana.
ENERGY STAR (EPA)
Per the AES Indiana residential rebates page, current HVAC-related rebates include a smart thermostat $50 and a heat pump water heater $600. The mini-split heat pump rebates on that page apply only to self-installed projects; for a technician-installed system, ask your contractor which AES Indiana incentives apply. Natural-gas furnace rebates are separately administered by Citizens Energy Group; check citizensenergygroup.com or the ENERGY STAR Rebate Finder for current gas amounts.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). Check your state energy office and utility for current rebate programs. See our HVAC financing options for what's still available.
