Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. In Rapid City 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.
AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — both need a technician to diagnose.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding or rattling from the outdoor unit. Possible causes include a failing fan motor, a loose blower wheel, or worn compressor bearings. Turn the system off at the thermostat and call a technician.

HVAC in Rapid City, SD: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the South Dakota licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Rapid City Regional Airport (KRAP) sits at approximately 3,200 ft elevation on the eastern slope of the Black Hills, and per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00024090), Rapid City records approximately 7,252 annual heating degree days against only 607 cooling degree days, an annual precipitation normal of 17.44 inches, and an annual snowfall normal of 48.5 inches. The city averages 32.1 days per year above 90°F and a striking 174.4 days below freezing. The 11.9:1 HDD-to-CDD ratio and semi-arid precipitation make Rapid City a heating-dominant, dry market. A specifically Black Hills operational concern: per NWS Rapid City, Chinook foehn winds can drive winter temperature swings of 50°F or more in 24 hours, and the same orographic effect produces dramatic diurnal swings year-round — HVAC systems sized purely to ASHRAE 99% design days frequently struggle with overnight temperature drops that the design-day method does not capture. Cold-climate heat-pump specification (COP ≥ 1.75 at 5°F) is essential for any heat-pump primary heat at 7,252 HDD.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040, B25003, B25077 and B25035 for Rapid City city, South Dakota) report 31,961 occupied housing units in Rapid City with a median year built of 1978. Heating-fuel distribution: 63.6% utility natural gas (20,316 units), 31.8% electricity (10,150 units), and 642 on bottled/tank/LP gas. Owner-occupancy is 61.6%; the median home value is $270,000. South Dakota's residential average electricity rate of 13.24¢/kWh (EIA Electric Power Monthly) is near the U.S. average, but the gas-dominant heating profile and abundant native lignite/coal generation in the Black Hills region historically favored gas furnaces for primary heat. The 1978 median year built means many homes pre-date the 1979 and later envelope-tightening standards, making blower-door testing a high-value step before equipment replacement.
South Dakota State Resource
South Dakota does not issue a statewide HVAC contractor license. Instead, the South Dakota Electrical Commission regulates only electrical work, and HVAC mechanical licensing is delegated to local municipalities. Rapid City requires a municipal mechanical contractor license issued through the City of Rapid City Building Services Division — verify a contractor's current municipal-license status with that office before contracting. Anyone handling refrigerant must additionally hold a current EPA Section 608 certification under federal law. Mechanical/HVAC permit fees in Rapid City are set by the local Building Services Division.
