Paul and another man were here mid-September at the end of the day (it has taken me a while to post). They kept up a good energy level and put on a bit of a show with their friendly banter, which was nice considering it was their last call of the day. They had a friendly and considerate manner and it showed that they've been doing this for a while. The ducts looked very clean after they were done and they definitely removed a significant amount of dust and other junk from the duct work (I believe they sucked up a wrapper from a few decades ago). There was a bit of minor property damage to our water pump after they were done, which is the reason for docking a point, but I would consider using them again.
