Mr Duct was recommended by my AC service provider. They were very responsive, professional, and provided outstanding service. We were having a problem with a mildew smell from the AC every time it turned on. Mr. Duct cleaned all of the ducts, removing and cleaning every register, and went the extra mile by cleaning out any overspray from the popcorn ceiling that had been hiding in the ducts. That last item will help prevent mildew growth from returning and is an example of the value they provide.
