Dial One Professional Duct Cleaning

Dial One taught us to seal the joints of ducts in the basement with heat tapes, to reduce heat loss. They replaced the old duct tapes left by the previous company with heat tapes and drilled new holes in the duct to do a more thorough job. The person was very professional and answered every question that we asked. He sealed every vent outlet carefully and covered the hardwood floor to make sure he didn't leave any footprints. The machine was very powerful (i.e. with great suction)! I'm very satisfied with their service and will certainly recommend Dial One to everyone!
