PM is getting 2nd request for fixing AC within 1 month

[Artur A.]

Hi Guys. Mind sharing your opinion, please? For 1st request, PM said this is a temporary fix and he will share a quote for installing a new AC system. The cost of the repair was around $490 (diagnostics). Yesterday (less than a month from 1st request) I am seeing 2nd request that AC is not working from the same tenant. I am also transitioning to a new PM next month. What is your opinion? How to deal with this situation? Thank you
