I have a Goodman furnace that is in a hall closet. The unit get very hot when it runs. there is not a return air vent in the closet. but there are 2 return air runs that are flex that have become compressed (pinched) over time. These come from the back areas of the home. There is a 15 degree difference in the exit air . Would the lack of return air from these runs cause the unit to over heat ?
