The HVAC trainers we offer not only have the ability to teach students electronically how A/C systems work but also show them the fundamental principles of refrigerant not only through theory but visually seeing the change of state of the refrigerant through sight glasses. We offer trainers for all types of systems in today’s modern vehicles like the FOT, TXV, H-Block in R134A. They also come with valves placed throughout the system that you can close and open to simulate a restriction in the line. The blower motor has a variable speed to also show how that changes the refrigerant in the system.

The newest trainer in our A/C system lineup is our R1234YF sight glass trainer. This trainer shows all the components of a typical R1234YF system and has built in sight glasses in strategic places to show how the refrigerant changes states. Both the Condenser and the Evaporator have variable fans to show how that changes how the system operates.

Our electronic-only HVAC systems provide students with the ability to diagnose inserted faults in the system so they can follow flow charts and diagnose the problem quickly and accurately.

Our complete OEM-style HVAC systems combine the best of both worlds with the OEM components located in the orientation they would be in a car and operate just how they would in car. These trainers are driven by a large 220v motor in place of the car’s engine to turn the compressor and pump refrigerant throughout the system. These trainers have electronic faults for inserting problems into the trainer for diagnosis. You can also add the clear sight glass tubes to any of these trainers along with a restriction control valve for an added level of training.
