This is an awesome program with fantastic instructors. It helped me to prepare by understanding the structure required to pass the examination. Paul and Coleman were part of my support system which helped me navigate through the process and obtain my licensure. I am greatly thankful for this school!

I just passed my HVAC contractor exam on the first try after taking Paul Calvo's class. Coleman was my instructor. Timed test are difficult for me personally, but with the methods and game plan laid out by Coleman I was able to easily navigate through the exam. On a personal note, Colman took time out of his busy schedule to answer questions after I took the exam and greatly helped build my confidence going into the exam. Can't give praise to Colman and the experience with this program.

I failed my first time taking the state contractors exam prior to taking Paul’s course. After taking his course, I felt that I was more confident in the material. It showed when I retook the exam and passed. I ran out of time the first time I took the test. With Paul’s guidance, I was able to finish the test the second time with 30 minutes to spare. I definitely recommend using his services to better prepare yourself for your state exam.

I cannot say enough good about the Paul Calvo school for contractors. Paul and Colman are fantastic and really care about the success of their students. ... My instructor Colman taught me how to study properly and how to key in on important details that are needed to pass. Today I passed the business law portion and I now am a licensed residential plumber thanks to Coleman and Paul!!!
