Verify an HVAC contractor licence in Connecticut

Check an HVAC contractor's licence in Connecticut by number or by business name and get one normalized JSON record back, sourced from the Department of Consumer Protection (DCP).

Try a free lookup — no signup, right here on this page. For programmatic access, take a free API key — 250 requests a month, no card. Also on RapidAPI and, if you would rather not write code at all, the Apify Store.

Which CT classifications count as HVAC contractors

• HTG — Heating, Piping & Cooling Contractor — unlimited or limited
• SHM — Sheet Metal Limited Contractor

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/CT/HTG.0305801-D1" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: contractor-license-verification2.p.rapidapi.com"

HTG.0305801-D1 is a real CT licence (HARRY P CARPENTER & SONS) in this trade, so that call works as written.

What Department of Consumer Protection does not publish

• Surety bond

• General liability insurance

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