Fixr, updated August 29, 2025, national data. The $8,750 figure is Fixr's benchmark job: 3 tons, split system, new ducts, 2,000 sq ft.

Because 84% of Greenville homes heat with electricity (Census ACS 2020-2024), what most owners replace is a heat pump, not a furnace plus a separate air conditioner. Fixr's heat pump range is $5,000 to $15,000, average $8,350. Heat pumps.

The permit, and who can do the work

North Carolina waives building permits for most home work under $40,000, but not for adding or replacing heating or air-conditioning equipment (G.S. 160D-1110). A system replacement needs a permit and an inspection. Normally the installer pulls it and books the inspection with the county or city. If a company offers to knock money off by leaving the permit out, take that as information about the company. In North Carolina, installing or replacing an outdoor condensing unit or an air handler is heating contracting under G.S. 87-21, and it takes a heating license from the state licensing board. Home systems fall under Heating Group 3.

Sizing comes before brand

DOE's guidance is to size from a Manual J calculation of the house's actual loads; sizing by rule of thumb tends to oversize, and oversized systems short-cycle. In Pitt County that short cycle has a cost you feel. The unit hits the setpoint, shuts down, and never runs long enough to pull water out of the air, so the rooms are cool and still sticky. If the only measurement a contractor takes is your square footage, ask to see the Manual J. Sizing for a 2,000 sq ft home.

North Carolina's efficiency floor

DOE puts North Carolina in its Southeast region, where split central air conditioners under 45,000 Btu/h installed since January 1, 2023 must rate at least 14.3 SEER2. Split heat pumps have a national floor of 14.3 SEER2 and 7.5 HSPF2. A higher rating costs more on day one and less on every GUC bill after.

Which refrigerant you'll get

Anything built from parts made in 2025 or later will run on a refrigerant under 700 GWP, typically R-32 or R-454B, not R-410A. An R-410A system you already own can still be repaired. What the change means for you.

Credits and the GUC audit

Don't plan on the federal 25C credit: the IRS says it ended for equipment placed in service after December 31, 2025. Greenville Utilities Commission will do a free energy audit and talk through equipment sizing (call 252-551-1521). When we checked GUC's site on October 29, 2026 we didn't see an equipment rebate, so confirm with GUC before you count one in your budget.

Reading a replacement quote

• Shows the Manual J result and the tonnage it led to.
• Lists the outdoor unit and the indoor coil or air handler by model number, each with its SEER2 rating.
• Says what happens to the ducts: sealed, resized, or untouched.
• Includes the permit, the inspection, and hauling the old equipment away.
• Puts parts and labor coverage in writing.

Two quotes is my minimum on a replacement, and when they are far apart, the ducts are usually why.
