Hi all.
My furnace works OK, but when it starts up, the metal air corridor "expands" and makes a noise like it is inflating. It sounds like a sheet of flexible metal being waved in the wind or something.
When the furnace shuts off, I hear a quieter "deflate" noise, similar to the previous one.
Have any of you experienced something similar? How did you resolve it?
