Texas ACR Combined Endorsement Contractor Exam Preparation in Texas has been our specialty since 1972. School enrollment is complete with a Home Study Computer Program, Tutoring, and Live Seminars with real questions, answers, code references, and calculations to prepare you for the actual PSI state licensing exams.

The Contractors School offers the only Complete 3-In-1 System consisting of:

1) Our new Home Study Computer Program has 30 excellent sample exams to simulate both of your actual PSI exams! Candidates must pass both portions. First, the Environmental Air, and then the Commercial Refrigeration exam, each with a minimum score of 70%.

    • Tests 1-20 have actual questions in each sample exam to prepare you for the Environmental Air portion of the exam! 
    • Tests 21-30 have actual questions in each sample exam to prepare you for the Commercial_Refrigeration portion of the exam!

2) Weekend Seminar or Webinar!
3) Engineering tutoring help!

While most of our students pass their exams in 4-6 weeks, our system is a three month enrollment and allows for unlimited Home Study Practice Exams, Seminars, and Tutoring for a three month period. Questions, answers, and article references that you need to pass the new PSI state examination are contained in this new program. Choose this program if you are serious about passing your state exam with PSI. Go into the test prepared with the best Home Study Computer Program in Texas!

Our Sample Exams Simulate Your Actual PSI State Exam!

1. Using the duct size calculator provided, and based on the effect of compression of the flexible duct on the air flow efficiency, what would be the approximate CFM air quantity given the following variables? 15% compression, 10-inch flexible duct, 0.1 friction loss.

  • Correct Answer: ADI Duct Size Calculator – 200 CFM

2. Calculate the amount to heat in BTUs given a five pound block of ice that is frozen stable at 32 degrees F, and is to be heated to 82 degrees F?

  • Step_1: Not a required step, as the block is not below the freezing temperature of 32.
  • Step_2: BTU = Weight of Ice x Latent heat of fusion of Ice = 5 pounds x 144 BTUs/pound = 720 BTUs.
  • Step_3: BTU = Weight of Water x Specific Heat of Water x Temperature change = 5 pounds x 1.0 x 50 degrees F (82-32) = 250 BTUs.
  • Step_4: Finally, sum of the subtotals = 720 + 250 = 970 BTUs

3. How many BTUs does a 100 W incandescent light produce per hour?

  • Correct Answer: MR&AC – Heat from Lights is 1 W = 3.41 Btu/hr. Therefore, calculate the load = 100-watt x 3.41 Btu/hr = 341 Btu/hr

4. Determine the approximate low side pressure of R-22 at 5 degrees F.

  • Correct Answer: MR&AC – Appendix E, E.5 = 28psig

5. What would be the calculated power factor of a circuit operating on 120-volts that draws 9-amperes, if the output power is only 1000-watts?

  • Step_1: Calculate the Input power using Ohm’s Law P = I x E = 9A x 120V = 1,080 VA
  • Step_2: Calculate the Power Factor = Output Power / Input Power = 1000 Watts / 1,080 VA = 0.9259 = 93%

The Codebooks that are highlighted in RED are provided by our School via PDF files within the Home Study Computer Program.
