I insulated the end of the duct near the tap, then threw 3 pillows and a roll of insulation into the frig and it seems to be cooling quite a bit better. I checked this morning and it was at 30 degrees F. It's still working harder than I think it should. I am going to double wrap the duct work and get styrofoam to replace the pillows, I think that will do it. Next thing to try is a Keg!
