Course Description/Agenda
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.
