A/C System Servicing & R-410A Certification Workshop

Two-day Workshop

(Includes R-410A Certification and Take-Home Workbook To Use Later On The Job.)

This training experience explores the fundamentals of maintaining, troubleshooting and servicing air conditioning systems from a nuts and bolts perspective. R-410A technician certification testing 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.
  • HVAC/R installation technicians planning advancement to service positions.
  • 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 R-410A refrigerant training and certification is included this workshop
