1998 Honda Civic A/C

I recently replaced my a/c compressor, but lately i've been having problems with the idling and the a/c blow minimal air out from the bottom dash when its place on the "head and foot" cooling option. When the a/c in running it takes a while for the car to change gears. I lifted up the hood and noticed some water around the low pressure tube. Any help you can give me will be greatly appreciated.
