Educational Programs Classes
Residential Air Conditioning / Refrigeration
The LLC has focused its limited resources on providing services to low-income residents of Houston’s communities. Particular emphasis has been placed at addressing gaps in services for adult education and services to the elderly and disabled communities. This program is a twelve (12) week program, the first six weeks constitute the first half of the Bilingual Air Conditioning and Refrigeration Program where the student is going to learn the theory (terms, definitions, technical words, basic calculus, formulas, etc.)
The program design is based on the Bilingual Vocational Model, this means that the technical instruction will be offered in Spanish for the students who do not understand English, and at the same time these students will receive instruction in technical English related to the field of Air Conditioning and Refrigeration. The goal of this program is to empower students who are capable of completing the basic tasks for working in Air Conditioning and Refrigeration in entry-level and who have the ability to communicate in English with customers, their co-workers, and their supervisors. The students are urged to get their own books and hand tools as soon as they are able. The course schedule for the Basic Air Conditioning and Refrigeration course is as follows.
