Very sorry to use this page for this type of question, but don't know who to ask.... we are in need of someone reliable and capable who does furnace work on the side in the Spirit Lake area. We're currently living in Des Moines but need someone who can help with a possible chimney problem on a house in Spirit Lake. The regular furnace companies have evidently been too busy to get back to us. Thank you for any suggestions anyone might have! And again, I apologize for abusing this page.
