What should I expect to be billed to replace the I.D.Blower P/N 22307501?

I don`t live where you live,, labor and parts costs are different from state to state and city to city
Where I live maybe 200 to 300 bucks, and that's still yet according to the brand of furnace you have, it could be more.

You will know when you get the bill. Let us know what it is and we may be able to tell if it is fair.
