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 Charlotte, 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
Charlotte Douglas International Airport (KCLT) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00013881), Charlotte records an annual mean temperature of 61.4°F, approximately 3,058 annual heating degree days against 1,768.7 cooling degree days, 43.60 inches of annual precipitation, and only 3.5 inches of snow. The 1.7:1 HDD-to-CDD ratio and warm-humid Zone 3A classification make Charlotte a nearly balanced heating-and-cooling market, with summer humidity driving dehumidification demand and mild winters keeping heat-pump balance points favorable.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Charlotte city, North Carolina) report 361,100 occupied housing units with a median year built of 1994. Heating-fuel distribution: 53.3% electricity (192,386 units) narrowly leads 44.5% utility natural gas (160,873 units). The electric-majority share is typical of new-growth Sun Belt metros where central heat pumps are the dominant system architecture — a single outdoor unit handles both the 1,768 cooling degree days and the modest 3,058 heating degree days, and integrated electric resistance or heat-strip backup covers the handful of coldest winter nights.
NC Licensing Board for Contractors
Every HVAC contractor in Charlotte must hold a current state-issued Heating & Cooling Contractor License from the North Carolina State Board of Examiners of Plumbing, Heating & Fire Sprinkler Contractors. NC issues three heating-license classifications — H-1 (steam, vapor or hot-water heating), H-2 (forced-air systems over 15 tons of cooling capacity), and H-3 (forced-air systems of 15 tons or less). Under N.C. Gen. Stat. Section 87-21, systems installed in single-family residences fall under H-3 regardless of size; verifying the contractor’s active license with the NC Board at 919-875-3612 before authorizing work is the baseline due-diligence step. Permit fees for residential mechanical work are set by Mecklenburg County Code Enforcement (LUESA); contact LUESA directly for the current fee schedule. For current Duke Energy Carolinas Smart $aver rebate amounts and Piedmont Natural Gas incentives, visit the utilities’ sites directly or check the ENERGY STAR Rebate Finder with your Charlotte ZIP. The federal Section 25C tax credit was terminated for installations after Dec 31, 2025 (OBBBA, P.L. 119-21).
