You can actually carry on a conversation now without shouting when it runs - and it has more air volume.
Avoid oilless like the plague. I had one. The bearing gets hot and starts working its way out of the frame 'cuze it heats the aluminum frame that holds it in place.
If you go with just replacing the pump, buy oil. They don't all come with oil in 'em.
One can also enclose a compressor and line it with acoustic tile to reduce the noise. Just made sure you have adequate air flow into & out of the enclosure. This works best if you have it in a corner and can use and outside air supply. I've moved compressors outside under cover to 1) gain some room and 2) to reduce shop noise. If you live somewhere in snow country put it in a small or purpose built shed with a heater in the winter.
Went back & looked to see where you are. NE is certainly snow country. In Kearney NE I moved the air compressor outside into an existing small (4 X 6 or so) brick building and put a milk shed heater in it with a thermostat to keep it warm enough in the winter.
