Later in your studies in the Heat Pump course (HART 2449), you will be required to take the I.C.E . (Industry Competency Exam). This is an excellent study guide for this exam COURSE DESCRIPTION:A study of components, applications, and installation of mechanical air conditioning systems including operating conditions, troubleshooting, repair, and charging of air conditioning systems. (3hr Lecture, 3 hr Lab, 4 Credit Hr.) COURSE OBJECTIVES: The student will demonstrate systems applications; implement and demonstrate industry accepted refrigerant charging procedures; demonstrate air conditioning system installation procedures; and demonstrate component and part diagnostics and replacement.

Attendance is critical in this class. Students should make every effort to be in class on time and prepared for class. . CLASSROOM ETIQUETTE: The classroom serves as a learning environment for everybody participating in this class. To facilitate academic and personal growth for everyone, you are expected to be courteous and respectful toward the instructor and other students. While I encourage an informal and friendly classroom environment that facilitates discussion and exploration, we must still accommodate one another’s differing perspectives and opinions, if you have an emergency call or you are on call from your company, you will take your conversation in the hallway as quietly as possible (Do Not Disrupt the Class). There will be no cell phone conversations during class time and no texting. The instructor reserves the right to assign seating. Each student must adhere to the Student Code of Conduct. The Student Code of Conduct can be found in the current Eastfield College Catalogue, or on the web site. There will not be any profanity or texting in the class room or lab.Food and Drink Policy Food, drinks, and tobacco products are prohibited in Eastfield College classrooms. However, according to Eastfield College procedures, if in a non-lab class setting, food and drink may be allowed. This is left to the instructor’s discretion. WRITING EXPECTATIONS: In completing homework assignments, you must write out the question in a complete legible sentence. The answer must also be written in a complete legible sentence. No abbreviations or short words. Turning in a homework paper that does not meet these standards will result in the paper being returned to you with a comment to “Redo”. If I am unable to read your handwriting you will be asked to type your assignments COURSE EVALUATION: Your final grade will be made up of these parts: Daily work (Home work, pop quizzes, and other daily work) 100 points
