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.
