prep for the HVAC exam

Always check for the license requirements and which exam you want to sit for before you start your process.

The applicant will have to send in an application to the Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors.

Once the board has reviewed the request and decided that the applicant is suitable for a particular license they pass the information to the examination body. The body, in this case, is PSI Inc.

The examining body will then send the necessary information to the applicant.

Examination dates

The PSI sets the exam dates. The individual who wishes to sit for the exam will be sent materials with all information on which dates exams are held and the centers at which they will be held.

Exams happen on a regular basis. Exams are held daily in some of the centers such as Baltimore and Salisbury.

Exceptions for taking the exam

A person does not always have to sit for an exam for them to get a license. There are some exceptions to the rules.

An example is when a person is applying for an apprenticeship license. It requires no exam.

The other exception is when a person wants to apply for a journeyman license. The examination can be foregone on two conditions:

  • If the applicant has held an apprenticeship license for three years.
  • If the applicant has graduated successfully from a learning program supported by the board.
