This course is designed to help a technician to troubleshoot an HVAC system. Using step-by-step approach, we address both common problems and the ones often overlooked. We start without tools, simply by feeling, hearing and looking. Then we move onto using actual tools.
The attendee will be shown diagrams which help to make sense of instructions pertaining to performance of certain procedures necessary to properly troubleshoot an HVAC system.
We discuss temperature probes, refrigeration gages, an anemometer, an airflow hood, information they provide and steps necessary to achieve an accurate diagnosis of the problem.
We touch on superheat and sub-cooling as well.
