Timothy’s Answer

Electrical Schematics, especially ladder diagrams don't show the same length of wire we see in the equipment, but they're very simple to read if you pay attention to one component or circuit at a time. You don't need to have all the symbols memorized just spend some time reading diagrams print them out from equipment manufacturers literature portals and use a highlighter to follow the wires for the component you're trying to understand. Motors in different types of loads and pressure switches have different symbols which you'll learn as you begin to read the diagrams more. Just like how you learn to work on equipment effectively it's all about practice.

Timothy recommends the following next steps:

Look up the installation manuals and read some wiring diagrams from the manufacturers which offer their diagrams for free, Carrier and Goodman.
