While the frig is getting down to 30 degrees F, the pitcher of water is only at 37-38. The frig is set on 8 out of a max 9 thermostat setting. I wrapped a second layer of insulation around the duct work. This should give me an r-value of 12 on the duct work. Waiting to see if this helps. I will keep updating in case anyone is interested.
