Anyone ever deal with odor from a central vacuum system?

Maybe you could crack some windows and get some fresh air in there?
The best thing I ever found to get rid of smells is ammonia. I'd take a gallon of ammonia, get some plastic bowls, fill them up, and close the house/apartment up tight.
I'd return a week or so later and there wouldn't be a smell in the place.
