The lookup you want is at public.nclicensing.org/Public/Search. Search by company name or license number and you’ll know in about two minutes whether the plumber quoting your repipe is licensed for it.
One thing worth knowing before you search: in North Carolina, plumbing and HVAC share a board. If you’ve been hunting for a separate HVAC licensing database, that’s why you couldn’t find it.
One board, four trades
The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors licenses four things:
- Plumbing
- Heating and air conditioning
- Fuel gas piping
- Fire sprinkler contracting
So the same lookup handles the plumber fixing your water heater and the HVAC company replacing your heat pump. Electrical is a different board entirely, and general contracting is a third — see the table at the bottom.
The board is in Raleigh at 1109 Dresser Court, reachable at 919-875-3612 or [email protected]. They’re open weekdays but closed for lunch from noon to 12:30, which is the kind of detail that saves you a wasted call.
Running the search
Start with the business name. If that comes up empty, try the license number off their estimate, or the owner’s last name.
The owner’s-name thing catches people out constantly. A company trading as “Mountain Air Heating & Cooling” may hold its license under an individual’s name. An empty search on the trading name isn’t evidence of a problem — it’s just an incomplete search.
What an active license actually means
It means the contractor met the state’s requirements and is current. It does not mean they’re good, insured, or available. Treat it as a filter that removes the people who shouldn’t be touching your house at all, then do your own diligence on everything else.
Expired, inactive, or suspended is a full stop. Gas piping and water under pressure are both unforgiving, and neither is where you want to save a few hundred dollars.
Why Asheville makes this a bigger deal
Two local realities push plumbing work here toward the complicated end.
The housing stock is old. Galvanized supply lines and cast iron drains are still common in the older neighborhoods, and the transition points where someone spliced copper or PEX onto original plumbing are where you find problems. That’s repipe territory, not a Saturday fix.
Winter bites at elevation. Cold snaps here reach crawl spaces and exterior walls that never got insulated properly, and burst-pipe season is real. If you’re outside city services on a well, add pump and pressure tank work to the list.
For HVAC specifically, the elevation swing across the county means a system sized for the wrong conditions will short-cycle for fifteen years. Ask whether the company does a load calculation on your actual house rather than sizing off square footage — that one question separates the good ones out faster than anything else.
The three boards
| Trade | Board | Lookup |
|---|---|---|
| Plumbing, HVAC, fuel gas, fire sprinkler | State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors | public.nclicensing.org |
| Electrical | NC State Board of Examiners of Electrical Contractors | see our electrical guide |
| General contracting | NC Licensing Board for General Contractors | see our contractor guide |
Questions worth asking after the license checks out
- Whose license does this job run under? You want a name.
- Are you pulling the permit? For anything beyond a straightforward repair, they should be.
- Can I see the certificate of insurance? The certificate, not a policy number.
- For HVAC: are you doing a load calculation? If the answer is “we’ll match what’s there,” keep calling.
