The answer to 'ductwork leaking water' is that there are several common causes, including condensation buildup, cracks or holes in the ductwork, and issues with the HVAC system itself. Symptoms can include water dripping from the vents, musty odors, and visible signs of moisture. Solutions can range from simple DIY fixes like sealing leaks to more complex repairs that require a professional HVAC technician.
If the leak is minor and easily accessible, you may be able to seal it yourself using duct sealant or mastic. However, if the leak is in a hard-to-reach area or is caused by a more serious issue like a problem with the HVAC unit, it's best to call in a professional. They can properly diagnose the root cause and make the necessary repairs to stop the leak and prevent further water damage.
