Throughout some of our blogs and pictures, we have mentioned the damage reach of a house fire even a small one. In these pictures, you will see the cause of the fire as well as the downstairs air vent in the main house. This was an electrical fire in the garage with a freezer that carried soot and smoke damage well into the Tuscaloosa home. The air vent in the downstairs is completely black showing that HEAVY smoke and soot traveled through the HVAC unit and spread to the entire house. While your filter may catch a large portion, not cleaning the entire unit will prolong damage.
