I had Kleen-Flo come in and clean my duct work after I had another company with portable equipment clean them. The other company "see my review" was not the wisest choice. I called around for pricing and found Kleen-Flo reasonable with their pricing. The tech was very knowledgeable and friendly. The best part was the truck mounted equipment they used to do the cleaning. I couldnt believe the amount of extra dirt that came out compared to the previous company and was able to see the debris coming out with their camera system. I would recommend them to clean your house.
