Heating, ventilation, air conditioning, and refrigeration (HVACR) services are important in any region that experiences frigid winter conditions or hot, humid summers. Delaware can have both, which is why HVACR professionals tend to enjoy steady work and good pay.

In this skilled trade, you might be involved in designing, installing, constructing, maintaining, repairing, or altering HVACR systems and equipment intended for various heating and cooling purposes. 

However, you’ll first have to obtain a license from the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners. What licenses are available to you, and how do you go about obtaining them?

Delaware HVACR Licenses

Whether you’ve already been working as a journeyman or you’ve simply racked up years of experience working in the HVACR industry, you may be ready to take the next step in your career by obtaining a master-level license. There are two options to consider.

With a master HVACR restricted license, you may offer services under one of several specialties, including:

• Heating (forced air systems, ventilation, and gas piping)
• Heating (hydronic systems and gas piping)
• Air conditioning
• Gas piping
• Refrigeration
• Commercial hood systems

With a master HVACR license, however, you can work in all these areas by designing, installing, servicing, and modifying all types of HVACR systems and equipment.

Requirements to Obtain Your License

Before you can apply for a master license, you must first prove an acceptable level of experience. This could include a certificate of completion from a journeyman apprenticeship program, along with proof of at least two years of experience (following certification) working under the supervision of a licensed master HVACR professional.

Alternatively, you could submit proof of seven years of experience working under a master HVACR supervisor. If you’re pursuing a master HVACR license, you’ll also have to submit license verification from any state and/or jurisdiction where you’ve held a license (including current licenses), along with a copy of your chlorofluorocarbon (CFC) certification card.

The same requirements apply for master HVACR restricted licenses, except you only have to submit the CFC certification card if you’re applying for air conditioning or refrigeration specialties. All applicants will also have to pass a state exam before they can obtain a license.

Delaware HVACR Exam

Once you’ve submitted the required documents and received board approval for your application, you can schedule a date for your Delaware HVACR Exam. Both master HVACR and master HVACR restricted professionals must pass this exam to obtain a license. This open-book test features 100 questions covering topics like:

You’ll have four hours to complete the exam, and you must answer at least 70 questions correctly to receive a passing score.
