Alabama HVAC Exam Prep: 1,450 Practice Questions for the Certified HAC Contractor Exam
PassProfessor’s Alabama HVAC Exam Prep is built for candidates for Alabama’s certified Heating and Air Conditioning (HAC) contractor credential, issued by the Alabama State Board of Heating, Air Conditioning and Refrigeration Contractors. The bank holds 1,450 original practice questions: a 1,250-question HVAC core covering the trade itself, plus 200 Alabama questions on Alabama law and the HAC exam’s published content areas – the Alabama exam builds its business content into the same sitting.
Every question is an original item written for this program, and every question comes with an explanation for every answer: why the keyed answer is right and why each other option is wrong, grounded in the cited code, standard, manual, or rule.
The exam, in facts
- Alabama certifies two credentials under Title 34, Chapter 31: the certified HAC contractor and the certified refrigeration contractor. There are no journeyman, master, or apprentice license classes in current Alabama law.
- The HAC exam is administered by Prov, Inc.: open book, 115 questions, 300 minutes, 70% to pass – with the business content embedded in the same exam (31 of the 115 questions) rather than in a separate business sitting.
- Prov’s published HAC outline: Systems & Sizing 25 – business areas 31 – General Knowledge 12 – Equipment 12 – Piping 11 – Maintenance 11 – Electrical Applications 10 – Plan Reading 3.
- HAC references include the NASCLA Contractors Guide (14th edition), the International Residential Code 2021, Alabama Laws, Rules, and Regulations (2009), Manual D, Manual J-Abridged (8th edition), Refrigeration and Air Conditioning Technology (9th edition), the Trane Ductulator, and the NEC 2020. No IMC and no IFGC volume is on the HAC reference list.
- Applicants qualify with 3,000 hours of work experience or as graduates of an approved HACR curriculum, and new applicants post a $20,000 performance bond. The Board’s written examination fee is $175, paid to the Board rather than to Prov.
- Certification runs to December 31 each year, with $220 initial and annual active certification fees and 4 hours of continuing education a year (proof due before November 1). The contractor’s AL number is displayed at least 2 inches high on at least two sides of work vehicles and on documents and advertising.
How the practice program works
The full practice exam draws 115 questions in 300 minutes – the same length and time as the real HAC exam – weighted to Prov’s published outline across the bank’s 26 topics, and every attempt draws a fresh assortment, so no two practice exams are the same.
Each of the bank’s 26 topics has its own drill, so you can drill Alabama licensing law on its own or work the trade topics one at a time:

Questions
Which Alabama credential does this cover?
The certified HAC contractor credential – Alabama’s heating and air conditioning contractor certification. Alabama’s separate refrigeration contractor exam (90 questions, 240 minutes) draws on its own reference list; this program is built to the HAC exam, whose published outline the Alabama portion of the bank follows.
Is the practice exam timed like the real one?
Yes. The full practice exam allows 300 minutes for 115 questions, matching the Prov HAC exam. The real exam is open book; how you use references while practicing is up to you.
Are these real exam questions?
No. Every question is original to PassProfessor, written from Prov’s published exam outline and the cited references. Nothing here is copied or paraphrased from a licensing exam or a competitor’s bank.
What does the 70% benchmark mean?
Our practice exam is scored against a 70% practice benchmark, set to mirror Prov’s published 70% passing standard for the Alabama HAC exam. PRACTICE BENCHMARK ONLY — your score here is a study signal, not a result on the real exam.
