electrical question about my second ac

If you have a twenty amp outlet, I would use a cord rated for 20 amps. Use of a smaller (less amp rated cord) is asking for trouble. The NEC (National Electrical Code) does not allow you to use wire related for less amps than the breaker it is attached to. If the installer used a 20 amp outlet, there is a reason.

So how would I know if the plug is 20A?

Yes, you can use a heavy 15 amp cord in the 15A outlet. The contacts are exactly the same size in both the plug and the outlets of 15A & 20A devices. (According to Leviton)
Also, you'll find the AC only pulls about 12A running and about 13~14A starting.

ok, that's what I was worried about, maxing out the 15A plug. That's for the quick advise.
