The rpms will fluctuate especially with the A/C is on because the compressor kicks in and out which throws extra load on the engine and the frees up the load when it kicks out. The coolant radiator fans can also cause this by putting extra load on your alternator, all this being said the fluctuation should be minimal!

I would like to point out that although this is good information, it doesn't actually cover the original question fully, as the poster specifically said the RPMs are unstable with the A/C off, but is worse with A/C on. The answer here doesn't account for what's going on when the air conditioning is not on.

@fatihkasozi Faith, you'll have much better luck starting your own question. Assuming you also have a Hyundai Accent SE, please include the year, transmission and engine information and what you've done so far to try and figure out the problem.
