"Has anyone had their house air ducts cleaned? Who did they use, what did it cost, and were they satisfied? It was a while ago (2003) and cost about $550. We used Santa Barbara Steam Cleaning Company. They cleaned our furnace fan, registers, ducts and Chimney. They got a lot of gunk out of our ducts (they showed it to us). It made a big difference in the air quality within the house. We were very satisfied. They did not find any problems or try to sell us other services."
