Furnaces don't like mud daubers.

_I have been cleaning furnaces since it turned cold. I have found that mud daubers were especially bad this past spring and summer. Two of the furnace I found were completely packed in the burner area with mud nests. One so bad it had packed the intake blower and the burner to such a point that the blower wheels could not turn. I removed a total of 8 nests just from the intake and burner area.
It will save you some money if you keep a mud dauber screen over the furnace vent during the off season. It's a small investment to save a service call and more importantly, keep you warm during the early morning hours of winter!
Enjoy yourself! Go RVing...
