I don't know how to check the voltage at the box where we hook up?.
Don't check the box, check your Rv. It's not hard. Every RVer should carry a voltmeter (assuming you do not). IMHO this is the most likely cause of your problem, and if it is, taking it to a shop is a big waste of time and money, and won't solve it.
Get a voltmeter. When running the air, check the voltage at any of your ac outlets. Also check when NOT running any big load. If this is out of your comfort zone, find someone to do it for you. Report back.
Are you in a park with many other RVs running air? Does this happen in other parks?
