Air Conditioning & Refrigeration: 3-day Lab Seminar

Presented by National Technology Transfer, Inc.

This course helps technicians with both scenarios in a hands-on environment that simulates maintenance issues that occur in the real world. The participants practice with the test instruments used in the trade

Course Description

3-day hands-on Lab Air Conditioning & Refrigeration training:  
Maintaining air conditioning and refrigeration systems is two fold. Troubleshooting and immediate action is required to repair issues as they occur, and proper preventive maintenance can lessen the frequency of  the problems and lengthen equipment life.

This course helps technicians with both scenarios in  a hands-on environment that simulates maintenance  issues that occur in the real world. The participants  practice with the test instruments used in the trade. Service equipment such as manifold gauges, recovery machines, vacuum pumps, charging scales, leak detections and micron gauges are also used in the hands-on labs.

Upon request, we offer free 608, 410A EPA and HVAC Excellent Technician Certificate testing at the end of  this class.
