Just wrapped up a full duct cleaning for a family in Levelland! Been in this home 12 years without ever having ducts cleaned - you should've seen what came out! Used our power vacuum system with HEPA filtration to get every last bit of dust. Removed all vent covers and washed them separately (found a child's toy car in one - they were happy to get that back!). The main return trunk had a ton of pet hair buildup - no wonder they were having airflow issues. After cleaning, applied EPA-approved sanitizing treatment throughout the system. Also cleaned their dryer vent which was about 70% blocked with lint - serious fire hazard avoided! Showed them before/after pics and they couldn't believe the difference. Even noticed immediate improvement in house smell. Left them with tips for maintaining better indoor air quality.
