Waste of money! They originally quoted $99 for cleaning the flue. I ended up having to pay $450 because the flue was longer than 5ft and the service person said it was really dirty. Whether it was really dirty or not, he would have done the exact same thing and what he did was definitely worthy of charging me an extra $350. I wont waste money on this ever again. Cheaper and probably a better job if I just by the equipment for $100 on Amazon and do it myself.
