No. For several reasons, some of which are specific to the sanctuary itself (meaning the entire Akropolis, of which the Parthenon is only one part) and some of which are features of Ancient Greek religion more generally.

Religious practice in Ancient Greece was not indoor practice. Festival activities - including processions, games, recitation of poetry or drama, dancing, singing, animal sacrifice, and other kinds of dedication - all occurred outside. This included ritual practices that occurred on the Akropolis. Most of the time, ritual practice is centred around an altar - the Great Altar of Athena on the Akropolis - which could date back to the 7th C BCE - was probably in front of the old temple of Athena Polias (front = east face, so when you get to the top of the Akropolis you're looking at the back of the temples there). The 'Old Temple' (the foundations that are now visible between the Parthenon and the Erechtheion) was most likely the main place of worship on the Akropolis during the major festivals like the Panathenaea, and it's where the ancient olive wood cult statue of Athena was located - this is the statue that was given the dress offering that the Athenians gave to Athena each year - this may have happened inside the temple, or the statue may have been brought out. Either way, when things do take place inside temples it is restricted to a very small number of people. There's a good multiphase plan of the Akropolis here: https://www.researchgate.net/figure/The-Acropolis-site-plan-Source-212_fig21_317416569

'Regular services' that occurred on the Akropolis would have included annual festivals (like the Panathenaea, but several others would have involved the Akropolis, even of only part of them - for instance, the regional cult for Artemis Brauronia had a temple on the Akropolis). There would have been regular sacrifices that occurred on a monthly basis, and there would have been dedications being undertaken more frequently than that - even up to daily. In some ways, I suppose it depends what you mean by 'service'. Dedications and sacrifices would have included other ritual elements - like libation, prayer, perhaps singing, 'processing' (of a more or less formal kind) - so in that sense perhaps they could be considered 'services', but not all of these would have required a priest or priestess (or other religious official) to oversee them (and also priests were not religious specialists in the same way that Christian priests, or Jewish rabbis etc. are). There did not need to be a person who mediated between a regular person offering a dedication and the gods, so even if other ritual elements were included (like libation) then this could realistically have been done by a single person or small group. (There are other things perhaps to say about who would go to the Akropolis to dedicate things rather than go to more local shrines and sanctuaries and altars in their own demes).

In 480 BCE, towards the end of the Greco-Persian war, the Persians occupied Athens and destroyed the temples on the Akropolis. At the time, there were two main temples (though obviously lots of other smaller shrines and things) - one was the 'Old Temple' of Athena Polias, and the other was the 'Old Parthenon' - but, this had only recently been started and was no where near completion when this occurred. The building that was there before (the 'Old Old Parthenon') is what we call the Hekatompedon ('hundred footer') and we don't really even know what the plan of that temple was. After the destruction, the Athenians decided that they wouldn't rebuild the temples (ostensibly due to 'memorialisation' but really because they had other concerns that required their cash). After they brought the treasury of the Delian League to Athens in 454/3 BCE they need somewhere to stash all that money and other treasures. Temples already have a long heritage as treasuries - mainly as places to keep safe all the offerings that were given to the gods. So they began by rebuilding the Parthenon in 447 BCE (rather than the temple of Athena Polias, which - remember - is really the main site of religious worship because that's where the cult statue is kept), and the back room of the temple is the strong room where all that money was kept.

Now: this is not to say at all that individual people did not go into temples to pray or offer private dedications or whatever - the simple fact is that we don't know really to what extent the indoor spaces of temples were used, but they weren't used for things that might be called 'services'.
