After having Duct Cleanings done various times, I have to say I've never been more satisfied. They cleaned as expected, but were able to do so very efficiently. Though they didn't take very long, they still did everything I needed perfectly. They took the time to listen to how I wanted certain vents to be cleaned, which is never the case with companies I've hired before. All in all, for the best value for your buck this is to company to go to.
