The need for heating and air-conditioning exists all over, as residents in Tucson would suffer from heat exhaustion in the summer without air-conditioning while those in Buffalo in the winter would freeze without heating. Cooling and heating devices help regulate the temperature, humidity, and air quality in residential homes, commercial locations, and industrial facilities. Many items like food and medicine require refrigeration to keep them from spoiling. Technician’s repair, maintain, and install heating, air-conditioning, and refrigeration systems.  Our program trains these technicians.   Los Angeles Trade Technical College offers an Associate of Science, and an Associates of Arts degree in Refrigeration and Air Conditioning Mechanics; as well as their equivalent Certificates of Completion (Core major classes without general education classes).  What is the difference you ask?  The Science Degree is designed for day time implementation and for people that are looking to make first entry into the field.  A student taking the Science Degree program must be able to commit to fulltime student status which is approximately 21 hours per week.  This commitment in time is required to allow for all of the hands on training in laboratory applications that are utilized during the course of instruction.  The Arts degree program is designed for evening implementation and for individuals that are currently in the field and looking to improve their skills or learn new ones.  Limitations on available evening hours restrict the utilization of extensive hands on laboratory practices and the hands on application is assumed to happen at the place of employment of the student.  The evening program for HVACR Technicians can take some time to complete due to the limited hours available.  For this reason a Fundamentals of Refrigeration and Air Conditioning Skills certificate is also offered.  This is a valuable certificate to show proof of continuing education and skills improvement to aid in job advancement.  The classes that are part of the skills certificate can also be utilized for the degrees and certificates as your education continues.
