The single most annoying problem is when that air compress runs and takes down your breaker. You only have 15 amp service for standard electric line. You can actually work around by running a electric sub panel with 20 amp fuse. This will require you to replace all electric lines in the room and installing a sub panel. After this change, your compressor can run as more frequently without dropping the breaker. (but compressor can actually burn itself out due to heat build up) If tank space is a problem, you can also add a extra tank inline.
The second most annoying problem is noise. Man, that thing is loud!!!
