What Does AL-REFRIG Mean?

What AL-REFRIG Actually Means

AL-REFRIG stands for the Alabama Refrigeration Contractor Certification Exam - the site identifier used on this domain for a specific state licensing exam administered on behalf of the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors. The Board's own name for this credential is the Refrigeration Contractors Examination, while the testing vendor, Prov, Inc., lists the same exam under the title "Refrigeration." AL-REFRIG is simply the shorthand this site uses to describe that exact exam, and this article targets the commercial refrigeration contractor examination specifically.

If you searched for AL-REFRIG expecting something else, it's worth pausing here: several unrelated credentials in other states or industries also happen to use similar-sounding abbreviations. Everything on this site - fees, question counts, domains, deadlines - refers only to the Alabama refrigeration contractor exam described in the Board's rules and the Prov candidate bulletin. For a broader definitional overview, see What Is AL-REFRIG? and AL-REFRIG Meaning.

Who Issues It and Who Administers the Exam

Two separate organizations are involved, and understanding their roles clarifies a lot of confusion candidates run into:

• Alabama Board of Heating, Air Conditioning & Refrigeration Contractors - the state licensing authority. The Board approves your application, collects licensing fees, issues the certificate, and enforces continuing-education and renewal rules.
• Prov, Inc. - the third-party testing provider. Prov builds and delivers the actual exam content, manages the candidate bulletin, schedules test appointments, and processes cancellations and rescheduling.

Because the Board and Prov maintain separate reference lists and separate paperwork trails, candidates sometimes get tripped up matching one organization's terminology to the other's. If a document uses "Refrigeration Contractors Examination" and another uses "Refrigeration," they're describing the same AL-REFRIG credential.

Exam Format: Questions, Time, and Passing Score

The AL-REFRIG exam blueprint, sourced from the Prov candidate bulletin revised September 4, 2026, defines the following format:

• 90 computer-based multiple-choice questions
• 4-hour time limit
• 70% passing score

The test is open-book, which changes how you should prepare compared to a closed-book exam. You can sit for it at a Prov test center or remotely through Examroom after completing a system check. Only a simple four-function calculator is permitted - no scientific or graphing calculators. Highlighting, permanent tabs, and formulas handwritten in ink directly into your approved references are allowed, but movable tabs, added photocopied sheets, other handwritten notes, and outside exam-prep guides brought into the testing session are prohibited.

The reference lists matter here. The 2021 International Mechanical Code and the 2020 NFPA 70 National Electrical Code appear on both the Board's and Prov's reference lists, so these are safe to buy regardless of which list you follow. Beyond those two, the Board and Prov lists diverge on editions and titles - confirm accepted books directly with Prov before purchasing anything else.

The 17 Domains Behind the Acronym

AL-REFRIG isn't just a refrigeration knowledge test - it blends technical HVACR content with the business and legal knowledge Alabama expects from a licensed contractor. The official blueprint breaks the 90 questions across 17 domains:

General Knowledge and Systems & Sizing are jointly the largest domains at 14 questions each, followed closely by Piping and Maintenance/Troubleshooting at 13 each. Together, these four technical domains account for more than half the exam - roughly 54 of the 90 questions. Electrical Applications adds another 8. The remaining 13 domains, covering business and law topics such as contracts, lien laws, labor laws, payroll taxes, and licensing laws, are individually small but collectively meaningful, since Alabama expects licensed contractors to understand the legal and financial side of running a refrigeration business, not just the trade itself.

Eligibility: The 3,000-Hour Path or Approved Coursework

Under Code of Alabama section 34-31-28(c), candidates qualify for the AL-REFRIG exam one of two ways:

1. 3,000 hours of qualifying work experience, documented with notarized employer affidavits plus corresponding W-2s.
2. Graduation from an approved heating, air conditioning, or refrigeration curriculum, documented with graduation paperwork.

All applicants must also submit citizenship or lawful-presence documentation. One important caveat: the application packet still contains older eligibility wording referencing apprenticeship- or coursework-only routes. Before you assemble your packet, confirm directly with the Board whether those older routes are still accepted, since the packet language and the current statute don't always match perfectly.

Fees and What Happens After You Pass

The written examination fee is $175, paid to the Board and non-refundable. Paying by credit card adds a 4% service fee, so budgeting slightly above $175 avoids surprises. If you need to cancel or reschedule your Prov appointment, do it at least 3 business days before your scheduled time - miss that window and you forfeit the fee entirely.

If you fail the written exam, you submit a re-examination request through Form EA-5 or the Board's re-examination portal and pay another $175. Separately, under Rule 440-X-3-.07, the Board may approve a $375 practical examination after a failed written attempt, but only upon written request - it's not a mandatory second stage, and it must be held within 6 months of your last unsuccessful written attempt.

Passing the written exam is not the finish line. You still must submit a separate licensing application to the Board before you're authorized to work as a certified refrigeration contractor.

Active vs. Inactive Certification

Once you pass and the Board processes your licensing application, you choose between two certification statuses:

Active certification requires a business name and a $20,000 performance bond - note that $20,000 is the bond amount, not the premium you'd pay an insurer for it. Inactive certification is cheaper and bond-free, but it does not permit you to perform contracting work under the credential.

Renewal for either status is due annually by December 31. Miss that date and a $250 late fee applies on top of your renewal cost. Continuing education is normally required at 4 Board-approved hours annually, with up to 4 hours carryover to the next cycle and a first-renewal exemption under Rule 440-X-4-.10. Proof of continuing education is due before November 1; under Rule 440-X-4-.03 (effective July 14, 2025), hours submitted after November 1 but before January 1 trigger a $25 deficiency fee, and any deficiency-extension request must reach the Board before December 31.

AL-REFRIG Is Not an EPA 608 Card

One frequent point of confusion: state contractor certification and EPA Section 608 technician certification are two entirely separate credentials. Passing AL-REFRIG makes you eligible for Alabama contractor licensing under the Board's rules. It has nothing to do with the federal EPA 608 refrigerant-handling certification, which is a different process administered by different EPA-approved organizations. Don't assume one substitutes for the other when you're planning your career path in refrigeration work.

How to Study for What AL-REFRIG Actually Tests

Since the exam is open-book, effective study looks different than for a closed-book licensing test. Your goal is less about pure recall and more about fluency - knowing exactly where in your reference materials to find load tables, code sections, and NEC references quickly enough to finish 90 questions in 4 hours.
