The HVAC (Commercial) test is designed to measure the knowledge and skills necessary for entry-level to mid-level commercial HVAC technicians to perform installation, maintenance, and repair on systems found in commercial properties. The test evaluates key skill areas including Refrigerant Handling and EPA Regulations, Electrical Systems and Controls, Preventive Maintenance Procedures, Airflow and Air Distribution, Heating Systems, and Refrigeration Cycle and Cooling Systems. Candidates are assessed through a variety of question formats, including Multiple Choice, Multiple Correct Answer, and Essay Composition questions, with one or more questions scored using artificial intelligence. Questions are drawn from a large pool to minimize the risk of cheating, and one or more questions are subject to time limits to further deter cheating and enhance the predictive accuracy of the assessment.

The specific attributes measured include:

Following completion, the test produces a Candidate Selection Report that includes an overall score and detailed scores for each attribute.

The Candidate Selection Report also provides expert interview questions that help you probe critical or low-scoring areas, along with a guide for noting your evaluation of the candidate's responses. Consistent use of an interview guide is an important part of gaining better candidate insights and making better hiring decisions.

Note that while the HVAC (Commerical, Short) assessment is a useful and efficient instrument for confirming a base level of skill or knowledge about this important topic, it is not intended to pinpoint the exact level of candidate or skill. We recommend that skills tests, like this one, be used in parallel with other measurements, such as cognitive ability, job fit, and behavioral history. Each different type of test provides a valuable piece of information you can use when evaluating potential job performance.
