I'm trying to save space but also keep the noise down.

Do I need to add some holes in the back for exhaust? The cabinet certainly won't be air tight, but is
the door and hose hole enough?

Thanks.

It certainly needs an exhaust hole. If it will be used continuously
for any length of time, I would wonder about it overheating.

The exhaust hole needs to be much larger than the suction hose or it,
too, will reduce suction. Given enough exhaust area, I don't think
heat would be a problem. These are usually cooled by the exhaust.
