Which TX classifications count as HVAC contractors

• A/C Contractor 20,399 records
• A/C Technician 60,271 records

A record's classifications array carries these codes, so you can tell a licence that covers the work from one that merely exists.

Run it

curl "https://contractor-license-verification2.p.rapidapi.com/v1/licenses/TX/103" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: contractor-license-verification2.p.rapidapi.com"

103 is a real TX licence (MLN COMPANY) in this trade, so that call works as written.

Before you rely on it

A/C contractor is the business licence; A/C technician is the individual registration and does not authorise contracting.

What Department of Licensing and Regulation does not publish

• A status column of its own
• Issue date
• Surety bond
• Workers' compensation
• Disciplinary actions

Full coverage detail, including the caveats that apply to every Texas lookup, is on the Texas page.
