Double Diamond Duct Cleaning

I had Double Diamond come to our old house to clean the ducts and they did a great job, showing us the before and after, and explaining the process thoroughly. I decided to have them come back to clean our new house as well. They were just as professional and informative. They showed us the dirt and large items that were found in our ducts (trim, insulation, etc.) and recommended cleaning the 28 year old furnace and fogging the ducts to sterilize them of mold and allergens. I didn't even know this was possible. We have dogs and babies in the house and this recommendation was very welcome. I am completely satisfied with the work they did and would have them come back again!
