The lookup is at public.nclicensing.org/Public/Search. Type in the company name, hit search, and you’ll know whether the contractor quoting your heat pump replacement is licensed in North Carolina.
Then you’ll hit the part nobody warns you about. The result comes back with a classification code next to the name — something like H-3 Class II — and that code decides whether this contractor is legally allowed to do your job specifically. An active license is not a yes. It’s a yes to certain work.
Here’s how to read it.
Three heating classes, and they’re not tiers
North Carolina doesn’t issue one HVAC license. The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors issues three heating classifications, and they’re divided by the type of system, not by skill level. H-1 isn’t better than H-3. They’re different trades that happen to share a board.
| Class | What it covers | Where you’ll run into it |
|---|---|---|
| H-1 | Steam, vapor, and hot water comfort heating — boilers, radiators, hydronic systems, and the piping that serves them | Older Montford and Kenilworth homes with original radiators; radiant floor heat |
| H-2 | Forced air heating and cooling with a mechanical refrigeration capacity over 15 tons | Commercial buildings, large multi-family, institutional work |
| H-3 | Forced air heating and cooling, 15 tons or less — the ducted systems and heat pumps in almost every house | Effectively every residential job in Buncombe County |
The tonnage line is the one that matters most, and it’s less mysterious than it sounds. A ton is 12,000 BTU per hour of cooling capacity. A typical Asheville house runs somewhere between two and five tons. Fifteen tons is a small office building.
Which means: for residential work, H-3 is the class you’re looking for. If you’re replacing a heat pump, a gas furnace with AC, or a full ducted system, the contractor needs H-3. H-2 is a bigger license, but it’s a bigger license for a different animal — a contractor who only holds H-2 isn’t the obvious upgrade for your ranch house in Enka.
And if you own one of the older homes around here that still heats with a boiler and radiators, you need H-1, and a great many excellent H-3 contractors simply don’t hold it. That’s not a red flag about them. It’s a mismatch, and it’s the single most common licensing surprise for homeowners in the pre-war neighborhoods.
Class I versus Class II
Alongside the H number, you’ll see a Class I or Class II designation. This one’s simpler:
- Class I — the contractor can do that work in any building: residential, commercial, industrial.
- Class II — the contractor is restricted to single-family detached dwellings.
For most homeowners, Class II is perfectly fine. If you live in a detached house, an H-3 Class II contractor is licensed for exactly what you’re hiring them to do, and plenty of very good small residential shops hold precisely that.
It matters when your building isn’t a detached single-family home. Condo, townhouse, duplex, a unit in a converted building downtown — that’s where an H-3 Class II license stops covering the work, and where you want to see Class I on the result. If you’re not sure how your property is classified, the contractor should be. Ask.
Running the search properly
The search page takes company name, license number, individual name, phone number, or address, and every field is optional as long as you fill in one. There’s also a Classification Type dropdown, which is how you’d confirm that a specific contractor holds a specific class rather than squinting at abbreviations.
Two practical notes carried over from every license search in this state:
Try the owner’s last name if the business name comes up empty. A company operating as “Blue Ridge Comfort Systems” may hold its license under an individual’s name. An empty result on the trading name proves nothing until you’ve tried the person’s name too.
Use the “include like sounding names” option when you’re not certain of the spelling. Half the HVAC companies in Western North Carolina have some arrangement of mountain, air, comfort, and climate in the name, and it’s easy to search for the wrong one and conclude something alarming.
If a result confuses you, the board answers the phone in Raleigh at 919-875-3612, or you can email [email protected]. They’re closed for lunch from noon to 12:30.
Why there’s no separate HVAC board
If you went looking for a standalone North Carolina HVAC licensing database and came up empty, that’s because plumbing, heating, fuel gas piping, and fire sprinkler contracting all sit under one board and one search tool. It’s the same lookup either way. We’ve covered the board itself and the general search process in our NC plumbing license guide — this piece is about reading the heating classifications once you’re there.
Electrical is a genuinely different board, and general contracting is a third:
| Trade | Board | Lookup |
|---|---|---|
| Heating, plumbing, 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 |
The second credential nobody checks
The state license isn’t the only one in play. Anyone who opens a refrigerant circuit — every heat pump and AC job, in other words — needs EPA Section 608 certification, which is federal and completely separate from the North Carolina license. It won’t appear in the state lookup at all.
It’s a reasonable thing to ask about, and it’s a fair question precisely because it’s not on the search result you just ran. A technician who’s been doing this work legally will have it and won’t mind being asked.
What the mountains do to this
Two local realities are worth holding onto once the license checks out.
Elevation changes the sizing math. The temperature spread across Buncombe County is real — a house at 2,200 feet in Woodfin and a house at 3,500 feet up toward Fairview are not the same design problem, and a heat pump sized off square footage alone will short-cycle for the next fifteen years. Ask whether the company performs a Manual J load calculation on your actual house. If the answer is some version of “we’ll match whatever’s there now,” keep calling. That one question separates the serious companies from the rest faster than anything else on this page.
Old houses complicate the class question. Asheville’s older stock was frequently built around boilers and radiators, then had cooling added decades later by someone else. That’s how you end up with a house that needs H-1 for the heat and H-3 for the AC — sometimes two different contractors, and always worth sorting out before the first one starts.
Buncombe County requires permits and mechanical inspection on system replacements, and a licensed contractor pulls those as routine. If someone offers to skip the permit to save you money, understand what’s actually being offered: skipping the inspection.
Questions worth asking after the license checks out
- Which classification is this job running under, and whose license is it? You want a class and a name.
- Are you doing a Manual J, or matching the existing equipment?
- Are you pulling the mechanical permit? For a system replacement, they should be.
- Can I see the certificate of insurance? The certificate itself, not a policy number.
- Who holds the EPA 608 card on the crew doing my install?
None of these are hostile questions, and a good contractor will answer all five without breaking stride.
Frequently asked questions
How do I look up an HVAC contractor’s license in North Carolina? Search at public.nclicensing.org/Public/Search, the public database of the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. You can search by company name, license number, individual name, phone number, or address. If the business name returns nothing, try the owner’s last name — plenty of small companies are licensed under an individual rather than the LLC on the invoice.
What is the difference between an H-1, H-2, and H-3 license? They divide by system type, not by skill level. H-1 covers steam, vapor, and hot water comfort heating, which means boilers, radiators, and hydronic systems. H-2 covers forced air heating and cooling with a mechanical refrigeration capacity over 15 tons, which is commercial-scale work. H-3 covers forced air heating and cooling of 15 tons or less, which includes nearly every residential heat pump and ducted system in Buncombe County.
Which license class does a residential job need? H-3 in almost every case. A ton equals 12,000 BTU per hour of cooling capacity, and a typical house runs two to five tons, well under the 15-ton line. The exception is a home heated by a boiler and radiators, which needs an H-1 license that many residential HVAC contractors simply do not hold.
What does Class I versus Class II mean on an NC heating license? Class I lets the contractor work in any building, whether residential, commercial, or industrial. Class II restricts them to single-family detached dwellings. If you live in a detached house, Class II covers your job. If you own a condo, townhouse, duplex, or a unit in a converted building, look for Class I.
Is EPA 608 certification the same as a North Carolina HVAC license? No. EPA Section 608 is a federal certification required to handle refrigerants, and it is entirely separate from the state contractor license. It does not appear in the North Carolina lookup, so it is worth asking about directly for any heat pump or air conditioning work.
