This was the third time our ducts were being cleaned since we moved into our new home five years ago. This was the first time we hired Mighty Clean. We had used a competitor the previous two times. Mighty Clean removed chunks of drywall, and screws and other materials from our duct. Leaving us absolutely stunned and wondering what was done previously. They were reasonable in price, responsive and the quality of work was brilliant. I would recommend and did so to another family member.
