Seminar Overview

Available in both virtual and in-person, instructor-led formats, this two-day Hands-On Air Conditioning Maintenance and Troubleshooting course is designed for HVAC technicians looking to gain an in-depth hands-on understanding of how to find and repair system problems safely.  It is recommended that this course be taken only after completion of the Understanding Air Conditioning & Refrigeration course. 

Students in this course will be able to charge, evacuate, and troubleshoot an actual AC system as they would in the field. Proper maintenance and troubleshooting scenarios of multiple systems will be discussed to give the attendee the best understanding possible. Learning to use the proper tools is very important and service equipment such as vacuum pumps, manifold gauges, charging scales, multimeters, and more will be used in the hands-on applications. Learn from the experts on how to troubleshoot and repair an air conditioning system in the fastest and most efficient way possible.

This 2-day seminar is just $1,195.
