There are two types of HVACR licenses in Delaware:

  • Master HVACR License (unrestricted)

    Allows you to perform all HVACR services; to design, construct, install, maintain, alter, service, repair, or modify equipment or products including gas piping in heating and air conditioning, refrigeration, ventilation, or process cooling or heating systems.

  • Master HVACR Restricted Licenses

    Offered in several specialized areas. The restricted license only allows you to work on the ONE system your particular license covers:

    • Gas piping
    • Commercial hoods
    • Refrigeration
    • Air conditioning
    • Heating involving hydronic and gas piping
    • Heating involving ventilation, gas piping, and forced air

If you want to do work in more than one of these niche areas, then you’ll need to get an Unrestricted Master HVACR license.

Employer Considerations

Employers almost always prefer applicants who have or who are on their way to earning a master’s HVACR license. Additional employer preferences often include:

  • Optional certification from a national HVACR organization
  • Prior experience working in the HVACR industry
  • EPA Section 608 refrigerant certification
  • HVACR trade school or community college diploma or AAS in HVACR

Employers prefer graduates of college HVACR programs because an AAS or diploma is a concrete demonstration of vital industry skills. Many HVACR school programs also include a segment for EPA Section 608 controlled refrigerant certification.

How to Get the Experience You Need for an HVACR License in Delaware

You can qualify for a restricted or unrestricted master HVACR license once you fulfill these requirements:

  • Meet the experience requirement
  • Pass an exam for your master HVACR license (restricted or unrestricted)
  • Have the appropriate certification under the EPA’s Section 608 if you are applying for a master (unrestricted) license, master restricted air conditioning license, or master restricted refrigeration license (see EPA Section 608 Certification information below)
  • Have a clean employment and personal record that is free from administrative penalties, employment discipline, drug or alcohol abuse, and criminal convictions that could relate to the performance of HVACR services

You can fulfill the experience requirement through either ONE of these routes:

  • Completing an apprenticeship and becoming a journeyman

OR

  • Completing seven years of supervised HVACR work experience under a licensed master HVACR mechanic

Apprenticeship-Journeyman Route

You earn a wage and go to school during your apprenticeship. It includes the following:

  • Four years (8,000 hours) of supervised on-the-job training – 2,000 hours per year
  • 144 hours of classroom instruction each year

By taking this route to fulfill the experience requirement you must complete these three steps in order:

  1. Complete an HVACR apprenticeship – this is done under the supervision of a master HVACR licensee who holds the type of license you are pursuing (master HVACR license (unlimited) or a master HVACR restricted license in one of the six categories).
  2. Once you complete your apprenticeship you’re eligible to take a journeyman exam; when you pass it you get an HVACR journeyman certificate that entitles you to work as a journeyman and gain experience applicable toward your master electrician license.
  3. You must then work as a journeyman under the supervision of an appropriately-licensed HVACR master for at least two years.

Qualifying HVACR apprenticeship programs include those approved by the Delaware Department of Labor and the US Department of Labor’s Office of Apprenticeship. To be approved the apprenticeship program must meet or exceed the federal apprenticeship guidelines.

Sponsors of apprenticeships can include private employers, industry organizations, and labor/trade unions. For example, the union UA Local 74 Plumbers and Pipefitters in Newark offers an HVACR apprenticeship. To get more information about available apprenticeships do a search for companies in your area offering apprenticeships or contact the Delaware Department of Labor.

Your classroom instruction takes place at one of Delaware’s trade schools or community/vocational colleges with an HVACR program. It is possible to transfer related credits you’ve already earned toward your apprenticeship classroom education requirements. Check with your apprenticeship administrator for more information about transferring credits.

Once you’ve found an apprenticeship sponsor you complete an apprenticeship training agreement form and submit it to the Apprenticeship and Training Section of the Delaware Department of Labor.

Seven Years of Work Experience Route

Technician Inspecting A Gas Furnace

By taking this route to fulfill the experience requirement you must accumulate seven years of work experience in general HVACR work or in the specialty area for which you are pursuing a license (master HVACR license (unlimited) or a master HVACR restricted license in one of six categories).

This work experience must be supervised by a master HVACR licensee with the same type of license you are pursuing.

Once you have seven years of work experience under your belt you’ll need to pass the apprentice equivalency test. You initiate this by completing an application for a master HVACR license (restricted or unrestricted) with the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners.

After you fill out your license application the board will review your experience and send you information about registering for the Apprenticeship By-Pass Exam.

Once the board has notified you that you can take this exam you need to schedule your testing date by contacting one of the following schools:

  • New Castle County VoTech in Wilmington – (302) 683-3643
  • PolyTech HS in Woodside – (302) 697-4545
  • Sussex Tech in Georgetown – (302) 856-9035

Send the results to the board after you pass the exam by scoring at least 70 percent.

Applying for a License and Passing the Master HVACR Exam

HVACR Application with the State of Delaware

Once you’ve met all other requirements except for passing the master HVACR exam (restricted or unrestricted) you can fill out an application for licensure with the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners. Once your application is determined to be complete the board will grant you approval to take the appropriate master HVACR exam.

A complete application includes:

  • Proof of meeting the experience requirement – any appropriate records such as college transcripts, employment tax forms, and/or employment contracts
  • Proof of EPA Section 608 if needed
  • Application fee

Passing the Master HVACR Exam

The Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners grants you approval to sit for the exam by sending you an examination registration form. Send this completed form along with the specified examination fee to Prometric Testing Services. This is the company that Delaware has contracted with to administer the master HVACR exam.

The Delaware board maintains a webpage the details exam dates and locations. The exam is offered in the Dover/Harrington and Newark areas three or four times per year. You must score at least 70 percent to pass, and once Prometric issues you a passing score report send this to the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners.

There are two parts to the exam: (1) Business and Law, and (2) HVACR-Specific section.

(1) Business and Law

All applicants must take the business and law exam. You have two hours to complete 50 questions that cover topics from labor laws and project management to contracts and tax laws.

You are allowed to bring the following two reference books with you to consult during the exam (you can use earlier editions at your own risk):

(2) HVACR Specifics

The second part of the exam you take is related to the type of master HVAC license you are applying for. The exam for the master HVACR license (unlimited) is 100 questions with a four-hour time limit. It covers the following subjects:

  • General HVACR topics – 20 percent
  • Ventilation – 15 percent
  • Gas piping – 10 percent
  • Piping – 10 percent
  • Controls – 10 percent
  • Warm air heating – 10 percent
  • Low and high pressure boilers – 10 percent
  • Safety – 5 percent
  • Load calculations – 5 percent
  • Insulation – 5 percent

You’re allowed to bring these reference materials with you to consult during the exam (you can use earlier editions at your own risk):

  • International Fuel Gas Code, 2012 Edition, International Code Council
  • International Mechanical Code, 2012 Edition, International Code Council
  • 1926 OSHA Construction Industry Regulations, 2012 Edition, MANCOMM
  • ACCA Duct Slide Rule, Air Conditioning Contractors of America

If you are taking an exam for one of the six areas of the master HVACR Restricted license then your exam will cover general HVACR topics, safety, and content that is related to your specific area of specialization.

After you’ve submitted your passing results to the Delaware board you’ll receive your master HVACR license (restricted or unrestricted). At this point you can start your own business, provide HVACR services independently, hire employees to work for you, or work for an HVACR company without supervision.

Don't Forget

Renew your master HVACR license. Do this before it expires, which happens on all even-numbered years on October 31st. A few weeks before your license expires the board will mail you information on how to renew it online by paying a renewal fee.

HVACR License Reciprocity with Other States

If you have an HVACR license in good standing that was issued by another state, and the requirements for earning this license were substantially similar to Delaware’s, then you can apply for the similar master restricted or unrestricted license in Delaware. You’ll need to have your state’s HVAC/R licensing board fill out the verification of licensure form (included in the reciprocity license application packet) and return this to the Delaware board.

If you are granted a license based on reciprocity you don’t need to take a master HVACR exam.

If you have an HVACR license in Connecticut or Maryland you are not required to submit proof of fulfilling the experience requirement.

If you have an HVACR license from any of the following states you are required to submit proof of fulfilling the experience requirement:

  • Alabama
  • Alaska
  • District of Columbia
  • Florida
  • Georgia
  • Michigan
  • North Carolina
  • Oklahoma
  • Rhode Island
  • South Carolina
  • Virginia

If you are from any other state then you must submit a copy of your jurisdiction’s HVACR licensing laws and the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners will evaluate your experience on a case-by-case basis.

In general the board does not grant reciprocity for HVACR licenses that are issued by non-state agencies, such as county or city governments (with the exception of Washington DC).

Master Plumbing License

You’ll need a state-issued master plumber license in addition to a master HVACR (unlimited or restricted) license if the work you’ll be doing involves design, installation, construction, replacement, servicing, repair, alteration, or modification of the pipes, fixtures, and other apparatus used for bringing the water supply into a building and removing liquid and water borne wastes from a building. This license will also allow you to install and connect gas piping.

EPA Section 608 Certification

Holding Environmental Protection Agency (EPA) Section 608 certification is a federal requirement that applies to all HVAC technicians who work with certain ozone-depleting refrigerant in any capacity. Delaware automatically requires this certification if you are applying for any of the following licenses:

  • Master HVACR license (unrestricted)
  • Master restricted HVACR license – air conditioning
  • Master restricted HVACR license – refrigeration

There are three EPA certification options, depending on what types of work you’ll be doing:

For servicing small, self-contained appliances containing five or fewer pounds or refrigerant

To earn one of these certifications you must pass the EPA exam specific to the certification type. Your school, employer, or the state board can point you towards the nearest Section 608 exam site in Delaware, and you can potentially take a class, take your test, and earn your certification in the same day.

If you are working with motor vehicle air conditioning (MVAC) systems you must complete a separate Section 609 EPA-approved technician training and certification program.

The State of the HVACR Industry in Delaware

There is a reason why in 2015 Delaware had the highest concentration of HVACR jobs of all states in the nation (U.S. Department of Labor). It has to do with a perfect storm of factors that include climate, energy cost, growth, environmental awareness, and government-sponsored incentives that push the installation of the most energy efficient HVACR systems.

As reported in the news journal delawareonline, Delaware led New England and the entire Northeast in population growth between 2010 and 2014 – higher than New York, Massachusetts, Virginia, and Maryland. This means residential construction is booming, and indirectly implies that so are the commercial and industrial markets.

And in fact many important industries in the state are booming. The top four industries in the state – aircraft manufacturing, environmental remediation, healthcare, and finance according to a 2015 Newsmax report – are growing in pace with Delaware’s population. And as it turns out, residential building and the state’s top four industries are all heavily reliant on HVACR systems.

Combine this reliance with the second-highest cost of residential electricity in the South Atlantic (US Energy Information Agency, 2016), an environmentally-conscious population, and government policies that fund HVACR efficiency upgrades and you will start to understand why Delaware’s Office of Occupational and Labor Market Information projects the number of HVACR jobs statewide will jump by 17.9 percent in the decade leading up to 2024.

An example of one such government policy is the Delaware Division of Energy and Climate’s Energy Efficiency Investment Fund. This is a funding pool that does things like underwrite HVACR upgrades for businesses and industry. By funding these upgrades, this program gets a return of approximately $2.40 to the state’s economy for every dollar it invests, while at the same time providing a government stimulus for the HVACR industry.

HVAC TECHNICIAN SALARIES IN DELAWARE

In 2015 the US Department of Labor ranked Delaware as the number one state in the nation for having the highest concentration of HVAC technician jobs, confirming the high demand for HVAC technicians.

That same year the Delaware Department of Labor reported HVAC technicians earn a statewide average salary of $24.83, which translates into $51,641 per year. Also at that time the US Department of Labor reported experienced HVAC technicians statewide – those in the top 10<sup>th</sup> percentile – earned $69,440.

The Delaware Department of Labor shows job growth projections for HVAC technicians are also very attractive. Between 2014 and 2024 it estimates the number of these jobs will increase by 17.9 percent, with an average of 70 openings every year. That is significantly higher than the national projected growth of HVAC technician jobs during the same period, 13.6 percent.

Delaware residents don’t like to see energy wasted with inefficient HVAC systems, or to spend money on energy that goes out the window. Delaware residents in particular feel the pinch in their pocketbooks. The US Energy Information Administration reported that in 2016 Delaware had the highest residential and industrial electricity rates of all states in the South Atlantic region, and the second-highest commercial sector rate.

In a bid to encourage its economy to stay competitive and environmentally friendly, Delaware has developed a range of programs that include HVAC efficiency standards and incentive programs to encourage HVAC upgrades. These incentive programs underwrite future jobs and salaries for HVAC technicians.

One such program is the state’s Energy Efficiency Investment Fund. This is essentially a grant that commercial and industrial entities can apply for. An application is available to anyone who pays the public utility tax and who purchases electricity or natural gas from a distributor who also pays that tax. Those who are awarded this grant receive funding to pay HVAC companies for heating system upgrades that improve efficiency.
