Took me some time but decided to pull the trigger on getting the ducts and air return chase cleaned. Debris from original construction and a remodel. It was bad. Shopped around obtained quotes and went with Duct Works. Glad I did. No pressure, the process explained in detail and the price was very competitive. Cameron arrived as scheduled and put in a solid 3 hours work. Took his time to protect the walls and corners possible damage. The picture tells the story. Now I know where all of that fine particles and dust bunnies came from. I highly recommend this company. Very customer focused
