From getting your contractor’s license to becoming a Master HVACR, we will break down the application and examination process to help you become your best HVAC professional.

HVAC Licensing Requirements for Delaware

There are two different Master HVACR licenses in the state of Delaware that techs can pursue. Delaware’s Title 24 requires all apprentices, journeymen, mechanics, and others in the field to have an HVACR license if they would like to work unsupervised.

Having an HVACR license can give technicians freedom to work independently, making them quite the asset for any company. Restricted techs can work independently within their one field of specialty, while unrestricted license holders can work on any job within the scope of HVAC.

Let’s compare the scope and eligibility requirements:

Master HVACR  

With a Master HVACR license, you can design, install, construct, maintain, service, repair, or modify a product or equipment such as gas piping, A/C, refrigeration, ventilation, or process cooling or heating systems.

Master HVACR Restricted

With this license, you can provide all of the services listed above, but the master tech is limited to one of these specialties:

  • Heating - Forced Air Systems, Ventilation, and Gas Piping
  • Heating - Hydronic Systems and Gas Piping
  • Commercial Hood Systems
  • Refrigeration
  • Air Conditioning
  • Gas Piping
  • For masters that want to work in more than one of these concentrated areas, they must apply for an unrestricted license.
