Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. In Dayton 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 Dayton 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 Dayton summer heat is worth a same-day call. Electrical and refrigerant faults need a technician to diagnose.

HVAC in Dayton, OH: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Ohio licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
James M. Cox Dayton International Airport (KDAY) is the official NOAA reference station for Dayton. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00093815), Dayton records an annual mean temperature of 53.9°F, an average annual maximum of 63.4°F against an annual minimum of 44.5°F, approximately 5,149.2 annual heating degree days against 1,153.9 cooling degree days, an annual precipitation normal of 41.33 inches, and an annual snowfall normal of 25.0 inches. The roughly 4.5:1 HDD-to-CDD ratio makes Dayton a firmly heating-dominant market, but the 1,154 CDD means summer cooling capacity remains important.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 House Heating Fuel and B25035 Median Year Structure Built for Dayton city, Ohio) report 57,953 occupied housing units with a median year built of 1951. Heating-fuel distribution: 69.2% utility natural gas (40,099 units), 28.1% electricity (16,259 units), and 634 on bottled/tank/LP gas. The strong gas dominance combined with very old housing stock (median 1951) makes furnace AFUE upgrades, ductwork remediation, and air-sealing work particularly impactful in Dayton — many homes still operate gas furnaces and duct systems installed decades ago.
Ohio Licensing Authority
Ohio requires HVAC contractors to hold an HVAC Contractor License issued by the Ohio Construction Industry Licensing Board (OCILB). The OCILB administers examinations and issues licenses for HVAC contracting statewide. Verify a specific contractor’s current OCILB license status before contracting. Primary source: Ohio License Lookup.
Utility & Permit Sources
AES Ohio (formerly Dayton Power & Light) is the primary electric utility for the Dayton area. Current xlsx data indicates no active HVAC rebate program from AES Ohio at the time of research. Contact AES Ohio directly to verify whether any residential HVAC incentives have been introduced. Primary source: DSIRE — Ohio.
Mechanical/HVAC permit fees in Dayton are set by the City of Dayton Building Inspection Division. Contact the Division directly for the current mechanical permit fee schedule.
