Basic Air Conditioning & Refrigeration Troubleshooting
Introductory Aboveground Storage Tank Training

Course Type: Lecture or Lecture / Hands-on

EPA Certification Testing Available

As a student in this program you will be shown methods of troubleshooting HVAC problems in order to eliminate the need for calling in outside help. The topics

discussed will be relevant and practical. This program will help you fix the equipment faster and on your own. It was developed with the idea of making you a better troubleshooter. We will primarily be discussing small units such as through the wall units, window units, ice machines, refrigerators, and small area cooling units. But the discussion will be helpful for larger equipment as well, and the instructor will be happy to answer any questions he can concern an array of HVAC equipment. You will understand how these systems operate and how to repair them. This program is a very technical subject explained in non-technical terms.
