I had them clean out my ducts a year ago, but it still smells of smoke. When I called them a few days after saying I still smell cigarette/cigar smoke, they didn’t call back. At that time on their website, they said they would come back, but after looking again, I don’t see that on there any longer. I called again a month ago to see if they’d fix the issue, but I still haven’t received a phone call back. Next time I’ll make sure to research a company that guarantees their work.
