Heating and cooling in North Carolina

Real summers and real winters. Most homes have central AC plus a gas furnace or heat pump, and both seasons bring peak demand.

North Carolina licenses heating and air conditioning contractors through the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors (heating groups H-1, H-2 and H-3). County or city inspection departments issue mechanical permits.

Heat pumps are the most common system in the Piedmont and coastal plain, and crawl-space ductwork is typical. Summer humidity is high, and the mountains in the west are a colder, heating-dominated climate.

Charlotte, Raleigh-Durham and Greensboro make up the core of the state's HVAC market, with long humid summers and mild winters. The coast deals with hurricanes and salt air, and Asheville and the mountains need more heating capacity than the rest of the state.

Most common needs in a mixed and humid climate

  • Spring AC and fall furnace tune-ups
  • Heat pumps with backup heat
  • Summer humidity control
  • Ductwork in attics and crawl spaces
