Scheduled for all day cleaning of ducts to begin 8:30 am, Rodolfo arrives exactly on time. He did a quick check of ducts with his booties covering his shoes and then explained everything he was going to do. He did exactly what he stated and took pictures of each duct before and after cleaning. He even pulled apart the blower system and gave that a complete cleaning. Before moving the hose throughout the house he put barriers around any corner or piece of furniture that the hose might drag against to prevent damage. He was very thorough and tidy with all his work even cutting around the vents before their removal so the pain would not be damaged. Rodolfo really did an great job and still finished a couple hours early.
