Frequently Asked Questions

How do the changes in the definitions of the HVAC, hydronic, and refrigeration trades affect those who carry all three mechanical trade licenses? Do we need to purchase both the HVAC and refrigeration licenses?

The changes in these definitions may result in a reduction in the number of licenses an individual is required to purchase. Each individual holding a mechanical license will need to review the definitions and determine what trade licenses they are required to obtain.

For licensees who currently hold a HVAC and/or Refrigeration license and a Hydronics license you will be eligible for a new mechanical license for a single fee.

For licensees who currently hold a HVAC and/or Refrigeration license, you will automatically be converted to a single HVAC/R license.

The updated definitions are also posted on the board website at www.idph.state.ia.us/PMSB/Licensure

Can a person perform volunteer work on an owner’s principal residence without having to obtain a plumbing, HVAC, refrigeration, or hydronic license?

Is there a 30-day grace period for all licenses that allows renewing without penalty?

Yes, a 30 day grace period applies for any reason, including completion of CEU requirements.

  • For licenses that have lapsed 31 to 60 days after the expiration of a license, a $60 late penalty will apply.
  • For licenses that have lapsed 61 to 365 days after the expiration of a license, a $100.00 late penalty will apply.
