Jason came today to clean out our "new" HRV system and dryer vent -- them having been installed in 2017, and I was surprised and impressed with how much dust and lint Jason and his truck were able to take out of our air pipes. It's been money well spent. Jason communicated well with me before his arrival, told me how much it would cost and did the work efficiently and spotlessly. I will not hesitate to use Duct Dudes again when the time comes -- likely two years from now. Great job!
