Access the furnace and check the outlet ducts. I had removed the wooden cover which was located under the fridge when I was checking for mice. I found the flexible duct that supplied the kitchen area was cut almost in two ( a bunch of wiring was run right thru it!). It was a quick fix with some aluminum flashing and high temperature duct tape. Click on my name and check out my previous postings as I included a pic. Hopefully it's a quick fix for you. Good Luck Jim
