Any regular maintenance other than cleaning filters needed for Mitsubishi Mr. Slim?

Hi r/HVAC,

We moved into a house with a Mitsubishi Mr. Slim system and it has been working great so far. I just cleaned out all the filters today and was wondering if there's anything else I need to do as part of regular maintenance. Anything to be done for the outside unit? Do I need to call an AC guy every now and then to check/service things?

Thanks!
