text: I used AZ Chimney Sweep to clean our dryer ducts.  They did a good job, although they didn't really need cleaning but that was my fault.  We had the dryer vent ducts cleaned a couple of years ago.  I noticed alot of lint, and thought it would just be ready to clean again.\n\nHe did say that we should have to clean again for another 5 years or so.  However, just beware of the extra thirty dollars they sell you on the flex seal hose.  I thought that was a rip off, but I did need a new hose.  I think that for the amount of hose I needed and the 125.00 that I paid them, they could have just NOT CHARGED for a small piece of hose.  I think this flex hose is a real money maker form them.  It probably only costs them pennies on the dollar.  Anyway, that's business.\n\nOther than that, I did like the company.
