Can't seem to find a way to reduce ac noise and smooth vocal sound properly, please help!

Hi everyone,

I've only recently picked up podcast recording (we typically do livestreaming and video recording) So please excuse my novoice question. I have searched and tried a few solutions provided but haven't seem to find the best fix for my situation.

Our studio has adaquate noise dempening equipment, but recently AC in the building has been ramping up as summer approaches, and making cleaning up the audio very difficult. This hasn't seem to be an issue with video recordings since part of the audience's attention is distracted by the visuals, but with audio alone, it sounds like you are standing by the beach with waves crashing into your eardrums.

In this particular case, I have two people in the studio recordin an interview. Towards the end of the session, I failed to remind them to maintain proper distance with the microphone when the AC kicked on, one person sat too far back, and caused the microphone to take in A LOT of the AC noise in the background of her speech. I've wasted hours trying to clean it up and I'm truly at my wits end. Please help! Thank you.

ALso if you have any suggestions as to how I can reduce noise coming from an overhead AC vent with hardware, I'd love to hear them, thank you again!
