I want to thank you for the EM-2000-OT A/C SYSTEM TRAINER W/ORIFICE TUBE that you sold San Jacinto College. I taught an HVAC class that included high school freshmen. The students had to wait 3 to 5 weeks to get textbooks. The trainer proved invaluable; I was able to teach all of the basic concepts with that machine.
