  • Why You should take this seminar

    Our air conditioning training & refrigeration training covers the maintenance of air conditioning and refrigeration systems. The seminar includes troubleshooting and immediate action required to repair issues as they occur and proper preventive maintenance can lessen the frequency of the problems and lengthen equipment life.

    This seminar helps technicians with both scenarios above in a hands-on environment that simulates maintenance issues occurring in the real world. Participants of this air conditioning training will 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.
