Hands-on HVACR Electrical Troubleshooting, Refrigeration System Servicing, EPA Certification, and Preventive Maintenance Programs Workshop

A Four-Day Workshop

(Includes Professional-Grade, Take-home Digital Meter, Workbooks, and Certification)

This training experience explores the fundamentals of maintaining, troubleshooting and servicing HVACR systems from a nuts and bolts perspective. Each participant will be issued a profesional grade,take-home digital meter. EPA Section 608 or R410A technician certification is included in this workshop.



  • HVAC/R technicians who service residential and light commercial air-conditioning, heat pumps and refrigeration equipment
  • Service managers and maintenance supervisors responsible for developing training programs or evaluating HVAC/R technician and facilities maintenance personnel skills;
  • Facilities maintenance personnel.

In the hands-on refrigeration system portion, participants will use gauges and a temperature pressure chart to evaluate operating systems, use recovery equipment, vacuum pumps and re-charge systems.

In the hands-on electrical portion, participants will use digital and analog meters to test electrical system components, and wire actual circuits from schematic diagrams.

As a workshop participant in this hands-on HVAC training workshop you will have the opportunity to build your own personal foundation of understanding of the fundamental concepts of electricity, refrigeration and air flow in comfort cooling systems, then apply that information to develop effective troubleshooting skills. Information on R-22 refrigerant systems, as well as EPA Section 608 or R-410A refrigerant training and certification is included this workshop
