Default Screeching/hissing after off

Greetings Lexus community!

I own a 2015 RX 450h w/ 30k miles and started noticing something weird. After any drive (at least 10 minutes long), there is a hissing/screeching noise coming from the front passenger side area of the vehicle after shutting it off. It sounds like someone dropping coins down a rusty pipe. I've attached a video of the issue.


Is this something I should worry about? Thanks in advance!

Best,
AJ

Nope, no issues with the air conditioning. Everything is functioning normally and fluid levels are good.
