Yep. I have to go in there every night and wipe off all the dust and pull the filters out (which at this point, are hardly actually cleanable). I try not to run it on days we get relief (FINALLY seeing rain).Better clean the AC's filters daily. They're not made to handle that much dust and feather dander so it could be a fire risk.
I am going to have about ~30-40 birds in the coop next year so am considering taking out one of their windows to install a high negative pressure fan and maybe install a temperature sensor.
