Frankly you'd almost have to walk on water to get a 5 star review from me (sounds like your AC company could have had a chance) basically no one is 5 stars. I either have to be super impressed or super ticked off to leave a review. Ask for a review and i might do one but chances of getting 5 star are next to nil. Not my problem how the review system works.
As for asking for a 5 star review, to me it depends on how its asked, if it was something form the company saying "did we provide 5 star service, if so please leave a review and if not please contact "owner/manager, supervisor name"" that might be ok, if it was just "leave a 5 star review", that would probably earn them a two star or 3 star depending on where they started out to begin with.
