Sounds like low on freon. Those generally are not designed for service, probably cheaper to get a new one.

That's the most likly cause but a dirty filter, fan not running, dirty coils can also cause this.

Many of them will initially ice over when first started. They ice will melt after about 10 minutes and they will operate normally. If it is too cool where they are then the ice could get a foot hold and build up. Mine will do this in the basement when the temp gets around 60. Works fine in the summer though.
