Call Now — (844) 582-179524/7 call line · call to check availability in Winston-Salem
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.

HVAC in Winston-Salem, NC: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the North Carolina licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Smith Reynolds Airport (KINT, WBAN:93807) is the official NOAA reference station for Winston-Salem, North Carolina. Per the NOAA NCEI U.S. Climate Normals 1991–2020, Winston-Salem records approximately 3,497 annual heating degree days against 1,513 annual cooling degree days, 32.8 days per year above 90°F, and 63.6 days below freezing. The 2.3:1 HDD:CDD ratio places the Triad firmly in the heating-dominant Mixed-Humid (IECC Zone 4A) band — with more than twice as many heating degree days as cooling degree days, equipment selection should prioritize cold-climate heat-pump performance ratings (HSPF2) or dual-fuel configurations with a gas-furnace backup below the balance point. Winston-Salem sits at roughly 1,000 ft elevation in the Piedmont, producing slightly cooler summer minimums and more frequent freeze events than coastal North Carolina — a measurable factor for heat-pump defrost-cycle frequency and for condenser-pad freeze-protection during ice-storm events.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040, B25003, B25077 and B25035 for Winston-Salem city, North Carolina) report a median year built of 1980, with a heating-fuel distribution of 60.9% electricity and 31.6% utility natural gas. The roughly 2:1 electric-to-gas ratio reflects the gradual conversion of older Mid-Atlantic Piedmont gas-furnace stock to electric heat pumps. The 54.6% owner-occupancy rate is below the North Carolina state average (66.4%). The median home value of $208,200 reflects the mix of established neighborhoods (Buena Vista, Ardmore, Sherwood Forest, Country Club) and a growing downtown rental market. North Carolina’s residential average electricity rate of 14.64¢/kWh (EIA Electric Power Monthly) is below the U.S. national average.
NC Licensing Board for Contractors
HVAC work in Winston-Salem is licensed by the North Carolina State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors. The H-3 classification covers forced-air heating & cooling of 15 tons or less, and under N.C. Gen. Stat. Section 87-21 systems in single-family residences fall under H-3 regardless of size; larger commercial work falls under H-2 (>15 tons) or H-1 (water-based heating). The Heating Group examination is administered by PSI Testing Services, costs $100 per exam, and requires 2 years (4,000 hours) of supervised on-site experience. Contractor applicants also sit a 90-minute Business and Law exam. Verify a Forsyth County contractor’s active license status on the Board’s public lookup before signing — the lookup also surfaces any open or closed disciplinary actions. Anyone handling refrigerant in the course of HVAC service must additionally hold a current EPA Section 608 certification under federal law (CFR Title 40 Part 82). Local Forsyth County permit pulls run through the Winston-Salem / Forsyth County Inspections Division.
U.S. Department of Energy
Winston-Salem 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. North Carolina’s Energy Saver North Carolina program, run by the NC Department of Environmental Quality (DEQ), launched on January 16, 2025 and, per DEQ, reached Forsyth County in its December 2025 expansion phase. It offers up to $8,000 for an ENERGY STAR-certified electric heat pump through the HEEHR pathway for households under 150% of Area Median Income, plus a separate HOMES pathway for whole-home efficiency upgrades (up to $16,000 per DEQ). 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. DEQ says households can receive both Energy Saver NC rebates and utility incentives for the same product, but the combined rebates cannot exceed the product’s purchase price.
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.
