Connecticut HVAC License Renewal

Last reviewed October 2026 · 3 min read

Connecticut's Department of Consumer Protection (DCP) licenses heating, piping and cooling contractors and journeypersons, including S-1 and S-2 unlimited licenses and limited licenses such as D, B and G. Every heating, cooling and sheet metal work license expires each year on August 31, and renewing costs $150 for a contractor and $120 for a journeyperson. An expired license can be reinstated for up to three years; after that you reapply and retest.

The license isn't the only thing expiring

Most lapses that cost contractors work aren't the license itself. They're one of these, renewing on a different date:

General liability insurance policy
Workers' compensation policy (or exemption)
Certificates of insurance (COIs) you've given to clients and GCs
Commercial auto insurance

LicenseLedger keeps every one of those dates in one place and emails you before each one expires, with reminders far enough ahead to finish CE and paperwork.
