Finished a complete air duct cleaning at a 25-year-old home in Pasadena today. Wow! These ducts hadn't been cleaned since the house was built. Used our high-powered vacuum system and rotary brushes to remove heavy dust buildup, several dead insects, and found a child's toy car that had been lost years ago (homeowner got a good laugh from that). Also discovered and sealed three leaky duct sections that were allowing attic air into the system. Removed approximately 5 pounds of dust and debris from the entire system! Homeowner has two kids with allergies, so this should make a big difference for them. Air quality meter showed immediate improvement after service. Left them with new filters and showed them how to properly change them every month. They were amazed at how much cleaner the air felt immediately after service. Great job that will really improve their indoor air quality.
