When we bought our coach the air compressor came on every 15 minutes, after watching a number of the videos on YouTube that Richard posted gave a very clear explanation of the systems and how to track down leaks but one tool that I bought has been a lifesaver in time and effort is a ultrasonic leak detector, my hearing isn't good but believe  me somebody with excellent hearing cannot hear in the ultrasonic range. I bought a used ultrasonic leak detector on eBay for a very small amount of money and it has been fantastic for finding more than just air leaks it also detects Freon leaks.
