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.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. 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.
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.

About 30% of households heat with natural gas vs. 66% electric. The South Carolina grid averages $0.16/kWh.

HVAC in Greenville, SC: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the South Carolina licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Greenville-Spartanburg International Airport (KGSP) serves as the regional NOAA reference station for the Greenville, South Carolina metro. Per the NOAA NCEI U.S. Climate Normals 1991–2020, the Upstate area records approximately 3,019 annual heating degree days against 1,720 annual cooling degree days, 47.6 days per year above 90°F, and 54.4 days below freezing. The roughly 1.8:1 HDD:CDD ratio — meaningfully more heating-dominated than coastal South Carolina — reflects Greenville’s higher elevation (about 1,025 ft) along the Blue Ridge foothills. Equipment sizing in the Upstate must give serious weight to winter heating capacity in addition to summer cooling, and dual-fuel heat-pump configurations (electric heat pump primary, gas furnace backup below balance point) are common in higher-end replacement installs. Greenville’s position at the foot of the Blue Ridge escarpment also produces meaningful micro-climate variation across short distances — high-elevation neighborhoods east of downtown can run 5–7°F cooler than the city core during summer evenings, reducing the practical cooling load. Manual J load-calculation discipline matters more in the Upstate than in flat-coastal SC.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040, B25003, B25077 and B25035 for Greenville city, South Carolina) report a median year built of 1987 — reflecting rapid Upstate growth since the BMW Spartanburg plant opened in 1994. Heating-fuel distribution: 66.2% electricity and 30.4% utility natural gas. The 41.2% owner-occupancy rate is below the South Carolina state average (71.4%), reflecting Greenville’s rapidly growing rental market in and around downtown. The median home value of $453,300. South Carolina’s residential average electricity rate of 16.15¢/kWh (EIA Electric Power Monthly) applies statewide.
South Carolina State Resource
Residential HVAC work in Greenville is licensed through the South Carolina Residential Builders Commission (LLR). The Residential HVAC specialty pathway requires the qualifying party to demonstrate at least one year of supervised HVAC work experience, submit a $100 application fee with a current credit report, pass the PSI trade exam ($100 exam fee) plus the SC business and law exam, submit a $10,000 surety bond if any project exceeds $5,000 in total cost, and pay the $220 license fee. Licenses renew biennially with renewal-fee discipline strictly enforced — renewals postmarked after June 30 are subject to a $50 late penalty. Commercial mechanical work falls under the separate South Carolina Contractor’s Licensing Board with a financial-statement-based group classification. Verify an Upstate contractor’s active license status and bond on the LLR public lookup before signing a contract.
U.S. Department of Energy
Greenville is served by Duke Energy Carolinas, whose Smart $aver home improvement rebate program pays rebates on qualifying HVAC upgrades installed by a participating contractor, who submits the rebate application on the homeowner’s behalf. Duke’s site is customized by location; select your service area on the Smart $aver page to see current rebate amounts. As of September 2026, the South Carolina Energy Office says its federally funded High-Efficiency Electric Home Rebate (HEEHR) program (branded in South Carolina as Home Electrification and Appliance Rebates) and its HOMES program are not yet available, with availability anticipated in 2026. When it opens, HEEHR is limited to households below 150% of county Area Median Income, with up to $14,000 per household. Under DOE Program Notice 26-2 (effective May 29, 2026), HEEHR rebates cover upgrades from existing electric equipment to more efficient electric equipment (and new construction), not the replacement of gas, oil, or propane systems.
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.
