About Our Classes

Since 1970, Lindsey-Cooper Refrigeration School has been a leader in the field of training service technicians for the HVAC/R industry.

Our students come from a variety of diverse backgrounds. Many have no knowledge of HVAC/R, some have very basic information, and some have hands on experience. Therefore, our students and teachers realize small class sizes are beneficial to their education. The school continues to maintain their class sizes to 15 students or less. The advancement in technology has greatly impacted the hvac and refrigeration industry. We continue to move forward with our course curriculum in order to meet these challenges. More advanced electrical control systems have increased the schools focus on the electrical issues involving hvac/r technicians. The hands on electrical trainers in the lab are designed to emphasize and teach the students electrical troubleshooting. This will enhance their ability to understand and progress with the changes taking place in the air-conditioning, heating and refrigeration field. UI design

Our instructors designed the course specifically to give you information that is

1. Useful 2. Up to date 3. Practical 4. Theoretical

  • Heat
  • States of Matter
  • Pressures
  • Temperature
  • Heat of Compression
  • Humidity
  • Basic Refrigeration Cycle
  • High, Low Head and Suction pressure
  • Service tools and Instruments
  • Compressors
  • Condensers
  • Evaporators
  • Metering Devices

  • Meters
  • Thermostats
  • Anticipators
  • Rectifiers
  • Wiring Diagrams

LAB WORK-54 Hours hands on

About 80 percent of an HVAC technicians work is with electricity. So during the second week the emphasis will be on learning the flow of electricity.

1.You will analyze and test capacitorsures
2.Use an ohm meter to determine common, start and run windings on compressors
3.Diagnose compressors for open, short, or a ground
4.Electrically wire and locate problems in different trainers

In the lab there are several stations called "trainers". Here is where you will actually put into practice what you learned in the classroom. You will physically wire the different electrical components. When you have practiced these, you will then be required to wire the trainer for the instructor without notes!

Additionally you will have the opportunity to
1. Solder, swage, and flare copper tubing
2. Use an oxyacetylene torch
3. Charge beverage coolers and residential air conditioning units
