I've given you the code (per the IRC). Whether anything is used or not well... it's up to you to believe what the code says or not.

The electrical company's equipment stops at the meter. After the meter is the main/service equipment/ disconnect. If that is on the exterior wall in the vicinity of the condensing unit-- NO PROBLEM.

The unit does not require ANOTHER/SEPARATE disconnect-- Unless your AHJ has upgraded the requirement per the city/ county electrical standards.
