This TSA training workshop is designed for:

  • HVAC Technicians and Facility Maintenance Personnel

This hands-on workshop has been designed to meet the needs of both new and experienced techs who must troubleshoot and service the electrical systems in air conditioners, heat pumps, and furnaces. Workshop participants will learn how to use a digital multimeter. After a thorough explanation of how to use the meter, participants will test various HVAC equipment and components so that they know exactly how to use the meter when they return to their agencies.

Each workshop participant will be given a digital multi-meter.

Participants will also be provided a detailed workbook that explains how to do HVAC trouble-shooting, which they can use as a reference later on the job. This workshop will provide participants with the skills necessary to trouble-shoot the electrical components in modern HVAC systems. With proper safety procedures having been thoroughly reviewed prior, live electrical circuits will be used during the class to test electrical components.

Participants will learn the fundamental concepts of electricity, and apply that knowledge, firsthand, using a wide range of HVAC electrical components and digital test equipment. They will work from tech sheets and will receive individualized assignments to test HVAC components… all done under the direct supervision of the workshop leader, who is a skilled professional trainer in HVAC and mechanical areas, and who has had many years of full time working experience in the Industry. TSA certificates of attendance will also be presented to all workshop participants.


Day One, 8:00 am – 5:00 pm
Day Two, 8:00 am – noon
Major topics that will be covered during this training:
