The Greensboro rule
From the City's Building Permits FAQs, read 23 October 2026:
- "All electrical, plumbing and mechanical work needs a separate permit for each trade."
- Mechanical permits cover the "Installation or replacement of a furnace, condenser, boiler, chiller, solar, hot water or steam heating" system.
- "The price of the permit is calculated using the cost of the construction" for building work; trade permits use the item schedules below.
The fee schedule also prices duct work on its own ("Duct System Only", no equipment), so plan on a permit for a duct replacement in Greensboro too.
Who can pull it
A contractor licensed by the North Carolina State Board of Examiners of Plumbing, Heating & Fire Sprinkler Contractors, which licenses anyone who will "install, alter or restore plumbing, heating (includes air conditioning)" systems; the board adds that "Minor repairs and service work to plumbing and heating systems do not require a state license" (Consumer Awareness). A new condenser is an installation.
The exception is you. Greensboro's Residential Construction page issues homeowner mechanical permits when you own and live in the house (with proof), "You are going to do the work yourself", and you sign the City's affidavit of ownership and terms of permits and inspections. Refrigerant work also needs a technician with EPA Section 608 certification (US EPA), so the refrigerant side of a split-system swap usually goes to a licensed contractor.
How to apply and get inspected
- Apply at Development Services, 300 W. Washington Street, 336-373-2155 (Monday to Friday, 8 am to 5 pm), and pay at application.
- Two permits for most replacements: mechanical for the equipment, electrical for the circuit and disconnect.
- Inspections through APRIL, 336-373-2400, with the permit number (contractors also need their PIN), by 8 pm the business day before.
- Check the final on the GSO BI Scheduler. Finished permits read Final Inspection Made.
What it costs
From the City's Mechanical Permit Fee Schedule (Document #4200, dated 7/16/24):
| Item | Fee |
|---|---|
| Minimum inspection fee | $85.00 |
| Heat pump, air conditioner or compressor, up to 5 tons/HP | $15.00 |
| 6–7 tons/HP | $16.00 |
| Heating system up to 100,000 BTU (1–29 kW) | $15.00 |
| 101,000–150,000 BTU | $17.00 |
| Duct system only: trunk line / branch line | $7.00 / $3.00 each |
| Gas piping; gas connection | $10.00 each |
| Gas water heater, fired storage under 100,000 BTU | $10.00 |
| More than 3 inspections on a crawl-space house, or 4 on a slab house | $45.00 each |
A heat pump up to 5 tons is a $15 line item, so on a typical swap the $85 minimum is what you pay. The electrical side adds its own permit: the electrical schedule charges $10 for an air conditioner up to 4 HP and $85 minimum. Equipment prices are in HVAC replacement cost.
What 16,678 Greensboro HVAC permits show
| Measure | Greensboro HVAC |
|---|---|
| Permits on homes, October 2023 to September 2026 | 16,678 |
| Firms | 545 |
| Firms with a permit in the last 12 months of the window | 359 |
| Final inspection made (permits a year or more old) | 89.7% |
| Usual days from issue to final | 48 |
| 10th / 90th-percentile firm (10+ permits) | 66.9% / 98.3% |
| Firms with 10+ permits finishing under 70% | 16 of 145 |
| Busiest / quietest month | July (135) / February (75) |
Filing in July runs at 135 against 75 in February (100 is an average month), which is the case for replacing a tired system in late winter rather than in the first heat wave. Greensboro HVAC permits record no job value.

What this does not tell you
City of Greensboro permits only; Guilford County handles houses outside city limits. A final inspection does not check that the system was sized for the house. The fee schedules are dated July 2024; confirm when you apply.
How we know this
Permit rules and homeowner conditions are quoted from the City of Greensboro's Building Permits FAQs and Residential Construction pages, read 23 October 2026; fees from the City's Mechanical (Document #4200) and Electrical (Document #4100) Permit Fee Schedules dated 7/16/24; licensing from the NC plumbing and heating board's Consumer Awareness page, read 22 October 2026. Counts are City of Greensboro mechanical permits on homes, October 2023 to September 2026; finished share uses permits a year or more old, and days to final is the median from issue to the final inspection.
Numbers come from City of Greensboro building and trade permits, data through October 18, 2026. Nobody paid to be on this page and nobody can.
Questions
- Do I need a permit to replace my furnace or AC in Greensboro?
Yes. The City's permit FAQ lists 'Installation or replacement of a furnace, condenser, boiler, chiller' among the work that needs a mechanical permit. The wiring to the new unit is on a separate electrical permit.
- How much is an HVAC permit in Greensboro?
The City's mechanical fee schedule (Document #4200, 7/16/24) has an $85 minimum inspection fee. Line items are small: a heat pump or air conditioner up to 5 tons is $15, a heating system up to 100,000 BTU $15, so a typical replacement comes to the $85 minimum. Extra inspections are $45 each.
- Can a homeowner replace their own HVAC in Greensboro?
The City issues homeowner mechanical permits if you own and live in the house, do the work yourself and sign its affidavit. The state plumbing and heating board licenses anyone else who installs or alters a heating or air-conditioning system; it says minor repairs and service work do not require a license.
- How long does an HVAC permit take in Greensboro?
The usual Greensboro HVAC permit in our file reached its final inspection 48 days after issue, the quickest of the City's three trades, and 89.7% of those a year or more old got there.
- Do I need a permit for a mini-split in Greensboro?
The City's FAQ requires a mechanical permit for installing heating and cooling equipment, and the fee schedule prices heat pumps and air conditioners by tonnage, so plan on one. Ask Development Services on 336-373-2155 if you are unsure.
