If you are currently enrolled in an HVAC training course and would like to brush up on the skills that have been taught to you and refresh your mind about the components found in some common heating and cooling systems, try the following study tips. After mastering the concepts that your instructor introduced throughout the course, you will be well-prepared to take the final exam needed to become a licensed heating and cooling technician.
Practice Problem Scenarios And Solutions
Ask a classmate or family member if they would like to help you study. Sit down at a table with the other person and have them describe a fictional situation in which a piece of equipment has stopped working. Details, concerning what occurred prior to the malfunction and any strange noises that the air or heating equipment is making should be identified.
After you have received a full rundown on the machinery that isn't operating properly, verbalize how you would inspect and repair the machine. Allow the person who is helping you study to hold onto your notes so that they can refer to them as needed. Practice several different scenarios that involve replacing parts or making adjustments to a cooling or heating unit.
Identify Key Parts Of Equipment
If you have received a variety of handouts in school that have diagrams of air conditioning and heating units printed on them and key parts labeled, use narrow strips of tape to temporarily block out the names of the key parts. Make copies of the diagrams and use your memory to help you label the diagrams appropriately. Once you have labeled as many parts as you can, remove the strips of tape from the original handouts and compare your answers with the labels that were added to the handout.
List Hazards And Safety Gear That Should Be Utilized
Take out a blank sheet of paper and think about all of the potential hazards that you could be faced with while repairing equipment and write the information down. For instance, your instructor may have stressed the importance of turning off equipment before inspecting it to prevent the risk of electrical shock or they may have told you that you need to cover your hands with gloves when handling freon or working with tools that have sharp edges.
Try to remember other safety gear that should be utilized while working on equipment and list the items on the paper. When finished, review your notes to determine if your answers were correct. Check out a website like http://www.hvac-tech.com/ for more information and assistance.
Hi there, my name is Melissa Grayson. Welcome to my website about trade schools. When I was in college, I decided that I did not want to pursue my four-year degree. Instead, I transferred to a trade school to learn about the automotive industry. I pursued my passions by completing my trade school degree and quickly acquiring a job in my field. On this site, I hope to help others learn all they need to know about selecting and attending a trade school. I will talk about the various programs available across the nation. Please feel free to visit my site daily to learn more.
