Course Information

A/C & Heating Program

The air conditioning and heating technician training program is a comprehensive course designed to teach students the skills and techniques required for entry-level employment into the residential and light commercial heating ventilating and air conditioning (HVAC) field. Upon completion of this program, students will be able to install, service, and maintain typical air conditioning and heating systems found in the southern environment of the United States. We are Texas Workforce Commission (TWC) approved.

HVAC Classes

Students will learn with lectures, discussions, and hands-on experience in lab environments during our HVAC classes. They will also be exposed to a variety of actual equipment and mock-up situations designed to prepare them for fieldwork. The approximate time required to complete this program is 10 weeks. The certificate awarded is a Certificate of Completion in the Air Conditioning & Heating Technician Program.* Scroll down to view the HVAC class descriptions for this program.
