North Haven HVAC licensure at a glance

Connecticut licenses people, not companies, so this page counts both and says which is which: 44 current DCP heating, piping and cooling contractor licenses are held in North Haven, and 7 trade-name companies are backed by those license holders. A business appears here only when licensed contractors operate under a registered trade name, and each listing names the person whose license backs it. The state also defines a scope on every credential: 26 of North Haven's licenses are unlimited and 18 limited - shown as published, never ranked on, because scope authorises kinds of work rather than ordering quality. Tenure is what these pages rank on: the median North Haven license has been held 18 years, and the longest-standing license behind a trade-name company was issued in 1993. Licenses here expire on one statewide date per trade each year, so an expiration date says nothing about an individual company and none is shown per listing - it gates currency only. DCP publishes no insurance, no bond and no phone for any licensee, so Connecticut listings show none of the three. eLicense cannot link straight to a record, so every listing above shows its number for you to paste into DCP's eLicense lookup.
