Master HVACR and Master HVACR Restricted Licensure



Selecting Type of License

The type of license you hold determines the HVACR services that you are permitted to provide.

Master HVACR – A Master HVACR can design, install, construct, maintain, service, repair, alter, or modify a product or equipment including gas piping in heating and air conditioning, refrigeration, ventilation, or process cooling or heating systems.

Master HVACR Restricted – A Master HVACR Restricted can provide HVACR services limited to one of the following specialties:

  • Heating – Forced Air Systems, Ventilation, and Gas Piping
  • Heating – Hydronic Systems and Gas Piping
  • Commercial Hood Systems
  • Refrigeration
  • Air Conditioning
  • Gas Piping

If you wish to provide services in more than one of these specialties, you must apply for a Master HVACR license. If you already hold a current Delaware Master HVACR Restricted license, you must apply to upgrade to an unrestricted license.

You need a Master Plumber license in addition to a Master HVACR or Master HVACR Restricted license if you design, install, construct, replace, service, repair, alter, or modify the pipes, fixtures, and other apparatus used for bringing the water supply into a building and removing liquid and water-carried wastes from a building.  You can also install and connect gas piping. To apply for a Master Plumber license, see Master Plumber Licensure.


Information on How to Apply for a License in DELPROS

Applications are processed in DELPROS (Delaware Professional Regulation Online Services). The online license application process is simple and provides you with clear instructions throughout each stage of the application process. We strongly recommend that you understand what the requirements are for the license you are pursuing. Then, request and gather the documents you need before you begin the application process. Most of the information and forms are on this website. For further clarification of requirements, refer to your profession’s License Law and the Rules and Regulations.

In order to apply for a license or service request, you must have a DELPROS account. To create a new account or log into an existing DELPROS account, follow the instructions at the beginning of the application process. As part of the final steps of the application process, DELPROS instructs you to either “attach” or “upload” the required documents directly to your application and/or to “acknowledge” that you will either send them in yourself or make arrangements for “third-party” documents/forms to be sent to the Board office. Examples of “third-party forms” are transcripts from schools, employment verifications from a supervisor, and license verifications from another state. These forms usually require a signature, seal, or notary, therefore, must be mailed into the Board office directly. All documents received by mail are scanned and attached to the appropriate license records.

In DELPROS, you have the ability to save your application and return to it to edit/update information or upload documents for up to six months. However, if you do not submit your application within six months, you will have to restart your online application process. The Board office begins processing applications shortly after submission in the portal. You may check the status of your application in the DELPROS system throughout the whole process and we will correspond with you by email.
