Are air duct cleaning deals really a deal?
Or in other words, does air duct cleaning really do anything beneficial? Today's Living Social email has four different air duct cleaning specials. I have been thinking about doing it for awhile but have heard that it really does not do much and is a waste of money. Any thoughts or experiences?
Background: I have a 25 year old townhouse with two people and a cat. I know at least one of the previous owners had a dog.
