Eric and Nicholas arrived promptly and went right to work. They first reviewed each room to locate heating and cold air return vents and then covered the vents. They were very careful to set up mats so as to not damage wood flooring or moldings with the large tubes used to do the duct cleaning. They worked efficiently and to our surprise were finished with our 2,340 square foot home in two hours. They cleaned up and asked us to inspect each room to make sure we were satisfied with the work done and the condition of our home. We inquired about several other services and Eric told us we did not need the services. We are very satisfied with the work performed and would recommend Safety King.
