RV AC units can be checked very easily with a Amp meter. Compressor Amp draw based on Ambient temp will tell you the state of the system. Doug

First, Welcome, shoulda said that sooner, and

Clamp On AC Ammeter (known to many as Amprobe) is cheaper than a service call and less invasive than a test port. As I mentioned earlier, HF's cheap ones will measure AC Amps and also serve as a very basic Digital Multi Meter (DMM, sometimes called Digital Volt Ohm Meter or DVOM). If you want to be able to do more RV troubleshooting, more expensive "amprobe" type units will measure DC Amps, Capacitance (good for A/C troubleshooting) and Frequency (good for Generator troubleshooting).
Big Boxes like Lowes and HD will have clamp-on's. Sperry Snap is a common brand.
