HVAC Technician

By /

The first course will teach about the function of electrical controls, the interpretation of electrical diagrams and symbols, and the use of instruments for electrical troubleshooting procedures.

Preparation for EPA Section 608 Certification

Important:
Preparation for the EPA Section 608 certification exam is included as part of the academic program. However, the examination and certification are not included in the course price, as they are administered by an approved third-party testing organization in accordance with the guidelines of the applicable certifying body.

For this reason, each exam attempt requires an additional fee, which covers the costs associated with exam registration, remote proctoring, and administrative processing related to the external evaluation.

Learning Trade Center of Florida does not administer the examination, does not act as a testing center, and does not issue the EPA Section 608 certification.

Students receive academic preparation to sit for the EPA Section 608 exam, which is administered independently by an authorized third-party entity.
