Frs idle rpm fluctuation, vibration and fan/compressor noise, normal?

Hi all, very new here. I have a 2014 Scion FRS auto. recently noticed when the car is idling at working temperature with AC on, I can periodically (about every 7-10sec) hear the fan/compressor kicks in and makes a rather loud noise for couple secs. normally my car idles stably at 650rpm. whenever the compressor/fan noise comes alone, the rpm would jump to 900-1k, then quickly drops back within couple seconds, then repeat. Also a noticeable vibration on the steering wheel.

I brought my concern to the dealership but every time they tried to convince me this is normal. Is it really a normal phenomenon? Should this be regarded as rough idling?

Thank you a ton in advance!
