What Does AL-REFRIG Stand For?

What AL-REFRIG Actually Stands For

On this site, AL-REFRIG refers specifically to the Alabama Refrigeration Contractor Certification Exam - the credentialing test administered for commercial refrigeration contractors who want to work legally in the state of Alabama. The acronym is shorthand we use here for search and navigation purposes; the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors officially calls it the Refrigeration Contractors Examination, while the testing vendor's internal exam title is simply "Refrigeration." All three names point to the same underlying test.

This distinction matters because the "AL-REFRIG" acronym is not unique across the internet. Other unrelated credentials in other states or industries use similar-sounding abbreviations. If you're researching this exam, make sure any resource you're reading is describing the Alabama Board's commercial refrigeration contractor exam - not a different program with different fees, question counts, or governing rules. Our companion piece What Is AL-REFRIG? goes deeper into how the name is used across Board documents, application forms, and the Prov candidate bulletin.

Who Runs the Exam: Board and Testing Provider

Two organizations are involved in getting you from applicant to certified contractor:

• Alabama Board of Heating, Air Conditioning & Refrigeration Contractors - sets eligibility rules, reviews and approves applications, issues certification, and handles renewals, continuing education, and disciplinary matters.
• Prov, Inc. - the third-party testing provider that builds and delivers the actual exam content, operates the test centers, and manages remote proctoring through Examroom.

You apply to the Board first. Only after the Board approves your application can you schedule your exam through Prov. This two-step gatekeeping is a recurring theme throughout the certification process - it shows up again at renewal, at continuing-education deadlines, and if you ever need to request a re-examination.

What the Refrigeration Contractors Examination Covers

The exam blueprint, sourced from the Prov candidate bulletin revised September 4, 2026, spans 17 domains. Here's the official question allocation:

Notice the imbalance: General Knowledge and Systems & Sizing jointly carry the most weight at 14 questions apiece, with Piping and Maintenance/Troubleshooting close behind at 13 each. Those four domains alone account for more than half the 90-question exam. Everything from Domain 7 through Domain 17 falls under business and law topics - a substantial but lower-weighted portion of the test that still requires real study time because so many small domains add up. For a domain-by-domain breakdown of what's actually tested inside each of the 17 areas, read AL-REFRIG Exam Domains 2026: Complete Guide to All 17 Content Areas.

Format, Fees, and Scheduling Mechanics

The Refrigeration Contractors Examination is delivered as 90 computer-based multiple-choice questions with a 4-hour time limit. A score of 70% is required to pass. It's an open-book exam, which changes how you should prepare - you're not memorizing facts word-for-word, you're learning to locate and apply information quickly under time pressure.

• Written exam fee: $175, non-refundable, paid to the Board. Credit-card payments add a 4% service fee.
• Where to test: Prov test centers, or remotely via Examroom after a required system check.
• Allowed calculator: simple four-function only - no scientific or programmable calculators.
• Allowed materials: highlighting, permanent tabs, and handwritten formulas in ink on your approved references. Movable tabs, added photocopied sheets, handwritten notes beyond formulas, and exam-preparation guides are prohibited.
• Reference codes shared by both Board and Prov lists: the 2021 International Mechanical Code and the 2020 NFPA 70 National Electrical Code. Other references differ between the two lists, so confirm exact accepted editions with Prov before buying anything.

If you need to cancel or reschedule, you must do it with Prov at least 3 business days before your appointment, or you forfeit the exam fee entirely. Approval and scheduling windows matter too - check AL-REFRIG Exam Dates 2026: Testing Windows, Deadlines & Scheduling before you lock in a date.

Eligibility Before You Can Sit for It

Under Code of Alabama section 34-31-28(c), you qualify for the 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 your graduation paperwork.

All applicants must also provide citizenship or lawful-presence documentation. One important caveat: the application packet still contains older eligibility wording referencing apprenticeship or coursework-only paths. If you're planning to qualify through anything other than the two routes above, confirm directly with the Board before you submit your application - don't assume older language on the form still applies as written.

Board approval has to happen before you can schedule with Prov, and once approved, your eligibility window lasts one year from approval date. Miss that window and you'll need to work through the approval process again. Full details are in AL-REFRIG Requirements 2026: Eligibility, Prerequisites & How to Qualify.

After Passing: Licensing, Renewal, and CE

Passing the written exam is a milestone, not the finish line. You still need to submit a separate licensing application to the Board before you're authorized to contract.

From there, certification comes in two tiers:

• Active refrigeration certification: $220 to obtain and $220 annually to renew. Requires a registered business name and a $20,000 performance bond (that figure is the bond amount, not the premium you pay for it).
• Inactive refrigeration certification: $110 to obtain and $110 annually. No bond required, but it does not authorize you to perform contracting work.

Renewal is due annually by December 31. Miss that date and a $250 late fee applies on top of your renewal cost. Continuing education adds another layer: normally 4 Board-approved CE hours are required each year, with up to 4 hours allowed to carry forward to the next cycle, and a first-renewal exemption under Rule 440-X-4-.10. CE proof 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.

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

Who Actually Takes This Exam

The Refrigeration Contractors Examination targets people pursuing commercial refrigeration contractor status in Alabama - typically experienced technicians moving into a contracting or business-owner role, or graduates of approved HVAC/R programs looking to formalize their credential. Because the exam blends heavy technical content (General Knowledge, Systems & Sizing, Piping, Maintenance/Troubleshooting) with a long tail of business and law domains - Business Organization, Risk Management, Project Management, Estimating, Labor Laws, Payroll and Employment Taxes, Financial Management, Contracts, Lien Laws, and Licensing Laws - it's built for someone who intends to run or help run a refrigeration contracting business, not just work as a field technician.

How to Approach Preparation by Domain

Given the weighting, your study time should roughly mirror the question allocation - not split evenly across all 17 domains. Here's a sample pacing structure built around the actual blueprint:

This pacing is only a starting frame - adjust it to your own background. If you already work daily with piping and diagnostics, you may need less time there and more on the business/law cluster, and vice versa for someone coming from a pure business background. For a structured walkthrough of building a full prep plan around this exact blueprint, see AL-REFRIG Study Guide 2026: How to Pass on Your First Attempt. To gauge where you stand before test day, run through timed practice questions on our practice test platform so you get used to answering 90 questions inside the 4-hour window.

Understanding exactly what score you need and how it's calculated also removes a lot of test-day anxiety - see AL-REFRIG Passing Score 2026: Exactly What You Need to Pass for the specifics.
