Multiple choice
The candidate: Reads a short situation, table or statement and picks the right answer, or every right answer.
You see: Whether the candidate knows the material well enough to apply it, not just recognize it.
15 questions in 10 minutes, served one at a time.
Roles this test fits
HVAC service and maintenance technicians, building maintenance and facilities technicians, chiller and plant operators, and apprentices nearing the end of their training.
See applied HVAC knowledge in context
Check diagnosis, not just job history
A resume can describe service experience, but it does not show how a candidate interprets an equipment log, gauge reading, or symptom. This HVAC assessment test presents short situations involving chillers, pumps, air handlers, air conditioners, and dehumidifiers.
Focus on maintenance decisions
Questions ask candidates to choose a likely fault, the next check, or an appropriate maintenance step. The multiple-choice format can ask for one right answer or every right answer, and tests whether the candidate can apply the material rather than only recognize it.
Cover three connected skill areas
The HVAC skills test covers chillers and water distribution, air distribution and ventilation, and air conditioners and dehumidifiers. Use those areas to focus a follow-up conversation on the equipment and duties relevant to your opening.
Keep the initial check brief
The test takes 10 minutes and has 15 questions. That gives you a focused skills signal before deciding whether to spend more hiring time on a work sample or interview. Candidates may use scratch paper for the light arithmetic.
What you get for each candidate
- Stayed on the test tab throughout
- No pasted answers
- Answered at a steady pace
Scores, profiles and integrity signals are evidence for you to review alongside an interview, never an automatic decision.
How the online test handles integrity signals
Each candidate receives a different set of questions from large question pools. Question order and answer options are shuffled. The browser receives one question at a time, and answer keys stay on HireValid’s servers. Timing runs on the server; reloading returns the same question with only the time left. Question text cannot be copied or selected, and a blocked copy attempt is recorded in the timeline. HireValid records signals such as time away from the test tab, pastes into answers, and answers faster than a question can be read. It summarizes these in an Integrity Score and evidence timeline for employer review; the signals never decide on their own. With the candidate’s consent, an employer can add webcam photos at random moments.
我们如何防范 AI 作弊 · Integrity signals
Use the result as evidence, not a verdict
Review the score alongside the candidate’s work history and a job-relevant work sample. For example, give candidates an equipment log or a set of gauge readings and ask them to explain their next check. Keep the sample tied to the duties of the opening, and assess the reasoning and maintenance choices you need for that role. Then use a structured interview with the same core questions for each candidate. The HVAC test result is one signal for a person to review, not a pass mark or a decision by itself. Its reliability is provisional and is reported once 200 candidates have completed it.
结构化面试问题
You see a chiller log with a change in readings and a reported performance issue. How would you decide what to check next?
Listen for a clear sequence that connects the stated readings and symptom to a next check. Ask the candidate to explain the reasoning rather than name a fault without support.
Occupants report a ventilation complaint in an area served by an air handler. What information would you review before choosing a maintenance step?
Listen for the candidate to use the situation’s details and relevant readings, and to explain how those details inform a practical check or maintenance choice.
A dehumidifier is not performing as expected. How would you investigate the symptoms and decide what to do next?
Listen for a reasoned approach to the stated symptoms, a relevant next check, and a maintenance step that follows from the information available.
Tell me how you would approach a pump or water-loop issue when the available readings are limited.
Listen for careful use of the information provided, acknowledgment of what remains unknown, and a sensible next step rather than an unsupported conclusion.
Understand scoring and benchmarks
Match the test to the role level
This is an intermediate test for HVAC service and maintenance technicians, building maintenance and facilities technicians, chiller and plant operators, and apprentices nearing the end of training. Its scenarios concern keeping equipment running and diagnosing faults from readings. It is not tailored to any one country’s codes, licensing, or regulations. Each question gives readings with units in full and does not require conversion between unit systems. If you are considering a broader hiring process, see the pre-employment testing guide for general context.
Connect test topics to daily duties
The questions draw on equipment logs, gauge readings, and symptoms from chillers, pumps, air handlers, air conditioners, and dehumidifiers. That makes the test relevant when the role involves chiller and water distribution, air distribution and ventilation, or cooling and dehumidification. Questions use plain wording, names and sites vary, and any pressure-temperature value needed is shown in the question rather than recalled from a chart. Candidates may use scratch paper; arithmetic is light. The format is multiple choice, and candidates cannot return to an earlier question.
Add a practical follow-up
The 4-question, 4-minute practice set gives candidates a chance to see the format before the 15-question hiring test. Use the result as one part of a review, then consider a work sample based on the role’s equipment and duties. For other openings, browse the test library. For how HireValid describes its test-building approach, read How we build our tests.
Fairness and accommodations
Questions cover equipment and practices common to most countries rather than any one country's codes, licensing or regulations. Each question states its readings with their units in full and never asks the candidate to convert between unit systems; any pressure-temperature value a question needs is shown in the question rather than recalled from a chart. Names and sites vary, the wording is plain, and the arithmetic is light enough for scratch paper.
You can give any candidate extra time as an accommodation. Results are evidence for a person to review, never an automatic decision.
Provisional: reliability is reported once 200 candidates have completed it.
Test details
A short, timed set of service scenarios from heating, ventilation and air conditioning work. Candidates read equipment logs, gauge readings and symptoms from chillers, pumps, air handlers, air conditioners and dehumidifiers, then choose the likely fault, the next check or the right maintenance step.
- Questions are in English.
- Aids allowed: Scratch paper.
- Each question is answered once, in order, with no going back.
- 4 practice questions, 4 minutes, before the timed test.

No. The questions cover equipment and practices common to most countries, not a particular country’s codes, licensing, or regulations. Readings state their units in full, and candidates are not asked to convert between unit systems. Any pressure-temperature value needed for a question is shown in the question rather than expected from memory of a chart.
Can candidates practice before taking the HVAC test?+
There is a practice set with 4 questions and a 4-minute time limit. It can help candidates see the multiple-choice format, including questions based on a situation, table, or statement. The hiring test itself has 15 questions and a 10-minute limit. Employers can use the practice set to explain the test format, not as evidence of a candidate’s job skills.
How should an employer use the HVAC test result?+
Use it as a signal for a person to review, alongside a role-relevant work sample and a structured interview. You might ask a candidate to explain a next check using an equipment log or readings, then ask the same open-ended interview questions of each candidate. The result is not a pass mark or a hiring decision by itself. Reliability is provisional and will be reported once 200 candidates have completed the test.
