Duct replacement as other said to do or clean the impossible. Viro succeeds where all others had failed.

Several companies attempted to clean this Colorado system and gave up. Others simply said it was impossible to clean and that the ductwork had to be replaced. The customer tried everyone until he found out Viro was doing work in his city. To his amazements, he was able to save tens of thousands of dollars in replacement costs and simply had his "impossible to clean" system cleaned by the Denver based Viro crew. Parts of the risers above the hoods were almost completely blocked. Here are the pics to enjoy.
