This company was recommended by a friend who also had their ducts cleaned. They arrived on time and did what was needed to be done. I didn't see what came out but noticed significantly less dust after the visit. We hadn't had our ducts cleaned for many years and this time they cut into our vent. See photo. I was not happy about the metal shavings left on the floor as we have little dogs but they did have to pack up quickly due to a really bad storm. Also when I spoke to other people they said that is actually normal like when roofers leave those pesky dangerous nails everywhere, ugh. So just something to be aware of for safety. Otherwise very happy may even rebook earlier as it had been so long.
