I had them come out and clean my ducts, I am in the hvac industry but didn't tell them, I wanted to see if they were going to attempt to do a bait and switch on me, the technician Shawn passed..lol he did a pretty thorough job, cleaning out all returns & supplies, you would have thought it was a rats nest from all the dust bunnies that came out of my ducts. I am a small business owner and prefer to use other small businesses, I have already referred him to several of my customers and will refer C'vinci Carpet Works to all my customers who are in need of duct cleaning, thanks again Shawn.
