A/C off of 20 amp service?
Has anyone ever heard of a single a/c unit not being able to start and run on a 20amp shore power circuit? We bought a new coach and the dealer says don't run a/c unless connected to a 30 amp servic...

My 2 cents.
It depends.
Size of AC 13.5 maybe 15 doubtful and I would not recommend.
Plugged into a circuit at home would require a dedicate circuit or knowledge on what else is on the circuit.
If an extension cord is used size matters. I use 50ft 10 gauge.
At the campground the outlets are usually burnt, pitted and resistive causing higher amp draw and lower voltage.
If you have low voltage the longer the AC is on the hotter the wire the lower the voltage requiring more amps to do the same work increasing heat.
I would not argue with dougtrainer and take his experience over what I have to say I base mine answer on my experience his experience is based or real life RV repair.
Simple answer sure it can be done BUT you really need to monitor the incoming voltage and shut the AC down at 108 VAC.
At 105AC the compressor is in self destruct mode if not today then soon.
Myself and plenty of other folks do it usually when loading or unloading the RV going on or returning from a trip.
