The answer to 'duct cleaning leaking water' is that a leaky duct system is a common issue that can occur after duct cleaning. This can be caused by damaged or disconnected ductwork, improper sealing, or excess moisture left behind during the cleaning process. Symptoms include visible water dripping, damp spots around vents, and musty odors.
In most cases, a leaky duct can be repaired by a professional HVAC technician. They will inspect the system, identify the source of the leak, and make the necessary repairs, such as sealing joints, replacing damaged sections, or improving insulation. Attempting DIY duct repairs is generally not recommended, as it requires specialized knowledge and equipment to properly diagnose and fix the problem.
