Nice people, I called for air duct cleaning because they did my attic insulation and they cleaned my sister's carpet and ducts. The price was better than most. Flat rate $ No up-sell. They power-brush the ducts. I had a big high power gas-powered vacuum in my back yard. Ran in my basement the biggest hose I've ever seen. The tech worked so hard cleaned up after himself. Going room to room. Vent to vent. Then the basement. My house smells so good and has stayed clean. I will have them come back next time.
