A short Q&A from today’s Detroit News:

Dear Glenn: I am considering hiring an air duct cleaning service to clean my home ducts as well as rid my basement of some minor mold. I have been researching local companies as well as a few franchise companies who say they can complete the work. Do you have a preference as to who would be more reliable and cost-efficient to do the work? Thank you and best regards.

Carl, via e-mail
