The State of HVAC Licensing in North Carolina, 2026

We searched Google for HVAC contractors across the Triangle and Greater Charlotte — the way a homeowner would — and checked every result against the North Carolina state licensing board. Fewer than four in ten clearly matched an active license. The rest weren't necessarily unlicensed. But a homeowner had no easy way to tell the difference.

The finding

Between August 17 and 20, 2026, we took 859 businesses that Google lists as heating and air-conditioning contractors across the Triangle and Greater Charlotte, and checked each one against the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors — the state's public license search. We matched by business name and, where available, phone.

64% of them — 551 of 859 — could not be matched to an active state heating-contractor license. Only 36% (308) clearly did.

The gap was consistent across every metro we looked at, from 50% to 74% — not driven by any single city.

What this means — and what it doesn't

This is the part that matters most, so we'll be precise. "No match found" is not the same as "unlicensed." A business can appear in our no-match column for several honest reasons:

• It operates legally under a license held in a different legal name than its Google listing (a qualifier's name, a parent company, an LLC that differs from the storefront brand).
• It's a duplicate or secondary Google listing for a business we matched elsewhere.
• It isn't really a contractor at all — Google's HVAC category also catches suppliers, lead-generation pages, and referral services that wouldn't hold a contractor license.
• It is, in fact, operating without an active license — which for most residential HVAC work in North Carolina is not permitted.

We cannot, from a name match alone, say how the 551 break down across those four categories — and we don't claim to. What we can say is the finding that actually matters to a homeowner: when you search for HVAC help in North Carolina, most of what you find does not clearly show a verifiable license — and there is no easy way, from a Google listing, to tell the licensed from the unverifiable. That gap is the entire reason a verification registry needs to exist.

Methodology

The sample is every business returned for HVAC-contractor category searches (heating contractor, air-conditioning contractor, furnace repair, and related) across the listed metros, via Google Maps, deduplicated by place ID. Each was checked against the North Carolina State Board's public license search by business name, and by phone number where the board record listed one. A business was recorded as matched only when we found an active license plausibly belonging to it; everything else was recorded as no match found, with the date of the check.

The rate above is computed only on metros where we recorded every checked business — matched and unmatched alike — so the denominator is complete: the Triangle (Raleigh, Durham, Cary, Apex, Wake Forest and nearby) and Greater Charlotte (Charlotte, Concord, Gastonia, Mooresville, Huntersville and nearby), 859 businesses in total. Metros we have since added to the registry by verifying licensed contractors only — the Piedmont Triad — are excluded from the rate, because we did not record their unmatched businesses and including them would understate the gap.

Limitations, stated plainly: license status reflects the public board search on the date checked and can lag real-world status; name matching is conservative and will miss licenses held under differing legal names; and a Google-category sample is not a registry of legal entities. This is a measurement of what a homeowner encounters when searching, not a census of licensed contractors.

The registry

This research is drawn from the same public checking that powers HVAC Registrar, which now lists 381 license-verified contractors across 17 North Carolina metros, each showing the license number, classification, status and the date we checked. Homeowners can check any NC HVAC contractor's license free, and see when every record was verified.

Related: we also tested whether a contractor's Google reviews predict whether they're licensed — they don't.

HVAC Registrar is an independent registry and is not affiliated with the State of North Carolina or any licensing board. "No match found" reflects a name-based search of the public license database on the date shown and is not a determination that any specific business is unlicensed. Figures describe a sample of Google-listed businesses, not a census of licensed contractors.
