Insulation in ac blower?

ibirman · 09-10-2023, 03:06 PM

The AC started thumping in our Que, I took off the inside cover and noticed insulatuion of some kind inside the blower wheel. I can pull it out with tweezers, but how did it get there? I pulled the top cover, the wheel is under a shroud and I dont think I can stand on the roof to remove it. Did a mouse get in there? I don't see any openings from the outside, and from the inside the blower has no room around it. Is it supposed to have insulation in it?

Is the AC in your Que ducted or non-ducted? Ducted would have multiple outlets in the ceiling, non-ducted the cold air only comes out of the AC cover in the ceiling.

There should not be insulation in the blower wheel, it does appear a mouse has made a nest in there. The ducted question was to try to figure out where it may have come in.

Thanks BenB, I think it's not ducted, I guess I have to take it apart to find the source, thanks for the help!

The non-ducted should be easier to find, the AC unit mounts on the roof and blows right out the vents below. Look for possible entry points around the square opening. The insulation most likely came from the space between the roof and inside panels.

Thanks for the replies, I opened it up and removed the insulation. The only opening I can find is the water drain, maybe a half inch hole, so I still don't know where the critter came from, I don't see any signs they are still there. Thanks again!
