Probably the AC condenser kicking on and off

Engine Rev During Idle? (2015 WRX)
Hi all,
Lately I've noticed that while I'm idling, I'll hear a "click" (or clunk?) come from the front end and the engine revs a couple hundred RPM, then drop back down immediately to where it was before i.e. idling around 700, click, then rev to 900, then drop back down to 700. It'll do this a few times then stop, so its not constantly happening. The car is warmed up by the way, and this will happen after 30+ mins of driving so I don't think its a temperature thing, though the temps have been around 4 celsius and under. Can someone explain what is happening or if this is normal?
Thanks and happy holidays!

If defrost is on. Then it does it.

Yes, the defrost engages the condenser.

Nope, the defrost wasn't on =/
What was on? If you have an auto climate system it may automatically engage.
Your description indicates the condenser for sure. But if you are worried take it to the dealer.

The car does have an auto-climate system but I didn't set it to auto (never do). Just cabin heat may have been on. Not sure if this is worth a trip to the dealer for I feel like I'm being paranoid haha.
Or perhaps the cooling fans are kicking on?
My bugeye kicks up the revs when the cooling fans turn on high

It's adjusted idle for the increased load from the AC compressor which runs when the defrost runs (normal with auto climate). It's normal.

So u set it so the word "Auto" actually disappears from the display?The car does have an auto-climate system but I didn't set it to auto (never do). Just cabin heat may have been on. Not sure if this is worth a trip to the dealer for I feel like I'm being paranoid haha.
Yup, that's correct. Turn the knob to turn on fans, then press the "Auto" button to get rid of the auto climate. Not sure why but I never use auto climate features in cars lol.So u set it so the word "Auto" actually disappears from the display?
Yeah I've done this. Like if you want to increase fan speed or aim air to windshield or floor. Is AC lit up or even floor/windshield?Yup, that's correct.

AC isn't lit up, but the fans are usually aimed at the floor only during the winter.Yeah I've done this. Like if you want to increase fan speed or aim air to windshield or floor. Is AC lit up or even floor/windshield?
