Renewal Requirements
To renew a license, applicants must submit an application for renewal (either online or via a paper application), pay the renewal fee, and meet the continuing education requirements for renewal.
Continuing education hours must be completed during the renewal term of the license to be eligible.
If your license expired over 365 days ago reinstatement requires either retesting or retaking all continuing education hours.
Reinstatement Requirements for Individual Licenses
If your individual license has expired for more than one year, it must be reinstated.
Reinstatement by CEU
You can reinstate your license by taking CEUs for each missed license period.
Reinstatement by CEU Deadlines
You must complete all CEUs within the timeframe listed under the CEU Requirement section
Your reinstatement by CEU must be submitted by the Reinstatement Deadline.
| Time Left in the Licensing Period: | CEU Requirement: | Reinstatement Deadline: |
|---|---|---|
| More than 2 years | Must be taken at least 1 year after the start of the previous licensing period. | Before the end of Year 1 of your current license period. |
| Fewer than 2 years | Must be taken at least 1 year after the start of the current licensing period. | Before the end of Year 1 of the following license period. |
You cannot receive CEU credit for the same course more than once. Repeated courses will not count toward reinstating a lapsed license. At least half of your CEUs must be completed in person.
Find details about the current licensing period on the License Period & Fees page.
How Many CEUs do I Need to Reinstate?
You need to meet the CEU requirements for each licensing period you missed. This includes CEUs for the current licensing period.

- Once approved, schedule your exam with Kirkwood Community College.
- A separate exam fee is due to Kirkwood.

Once reinstated, your license is valid until the end of the current licensing period. You will need to meet the CEU requirement to renew for the next licensing period.
Combining Licenses into a Mechanical License
For licensees that currently hold a HVAC/R and a hydronics license at the same level of master or journeyperson, you may elect to combine these licenses into a single mechanical license.
Renewal fees will be assessed as a single license if converting to the mechanical license. No fee is charged to combine licenses when it is done at renewal.
If you are renewing into the new mechanical license, there are special instructions when doing this via the public portal. In the instructions for individual renewals, see the section marked Combine to Mechanical.

Please carefully review the fees and required attachments for your renewal. Your application may be mailed back to you if your fees or attachments are incorrect.
