ExploreAbout this exam
The BTEB Refrigeration & Air Conditioning credential refers to the assessment side of the refrigeration and air conditioning trade programmes administered under the Bangladesh Technical Education Board (BTEB), the government board whose website lists result services for Diploma, HSC and SSC level examinations, short courses and other e-services. Candidates are typically trainees and students in technical school, polytechnic or short-course programmes who need to demonstrate competence before progressing or entering employment in the refrigeration and air conditioning trade. The published domain outline for this exam preparation page divides content evenly across five areas: refrigeration fundamentals; refrigeration systems and components; air conditioning fundamentals and load estimation; AC equipment, installation and commissioning; and maintenance, troubleshooting and safety, each weighted at 20 percent. That balance means a candidate cannot pass on theory alone or on hands-on skill alone; psychrometrics, refrigerant behaviour, component function, heat-load calculation, commissioning checks and fault diagnosis all carry equal weight. Preparation should follow the same order as the domains: secure the thermodynamics and pressure-temperature relationship basics first, then trace complete system circuits, then practise load estimation and installation checks, and finish with troubleshooting scenarios and safety procedures. Because BTEB does not publish a single unified national question count, duration or pass mark for this subject on the cited page, candidates should confirm current examination rules, syllabus and course structure through the board's official syllabus and examination-rules download sections and their own institute before sitting the examination.

What you'll study
About BTEB Refrigeration & AC Exam preparation
What format is the BTEB Refrigeration & Air Conditioning exam?
The preparation profile for this credential lists multiple-choice questions only. Candidates should verify the current paper structure, marks distribution and any practical component directly with their institute and the board's published syllabus, course structure and examination rules, because those documents govern the actual paper.
How many questions are there and how long does the exam last?
The cited BTEB page does not state a question count or duration for this subject, so no reliable figure can be given here. Check the syllabus and examination rules downloads on the board site and confirm with your own institute before your examination date rather than relying on second-hand numbers.
What score do I need to pass?
No passing mark for this subject appears on the cited source, so it cannot be stated. Pass requirements are set in the board's examination rules and in your institute's assessment scheme. Ask your instructor for the current rule, and note that theory and practical marks are often assessed separately.
How should I order my study across the five domains?
Follow the domain sequence: refrigeration fundamentals first, because pressure-temperature behaviour and the vapour compression cycle underpin everything else; then systems and components; then air conditioning fundamentals and load estimation; then equipment, installation and commissioning; and finally maintenance, troubleshooting and safety, which draws on all four earlier areas.
How difficult is the exam?
Difficulty depends on your programme and practical exposure. Because the five domains carry equal weight, candidates who are strong on installation but weak on load estimation, or strong on theory but weak on fault diagnosis, lose marks evenly. Balanced revision across all five areas is the most reliable way to reduce difficulty.
Can I retake the exam if I fail?
Retake and re-examination arrangements are governed by BTEB examination rules and your institute's registration process, and the cited page does not state a specific retake policy. Consult the examination rules section of the board website and your institute's examination office for the current procedure and any applicable deadlines.
What are the most common failure modes?
Typical weaknesses are confusing pressure-temperature relationships, misreading superheat and subcooling, mixing up sensible and latent load, skipping commissioning checks, and jumping to a diagnosis without a systematic fault-finding sequence. Safety questions also catch candidates who ignore isolation and refrigerant-handling procedure. Practise each area with worked examples.
Where can I find the official syllabus and examination rules?
The BTEB website publishes download sections covering syllabus, course structure and regulations, examination rules for diploma and other examinations, academic calendars, and previous question papers. Use those official downloads plus your institute's guidance as the authoritative basis for what will be examined.
Is this page officially connected to BTEB?
No. This is independent study material produced by an independent study platform. It is not affiliated with, endorsed by, or issued on behalf of the Bangladesh Technical Education Board. Always treat the board's own publications and your institute's instructions as the authoritative source for examination matters.
