Ductwork "sweating" or dripping water is typically caused by condensation forming on the surface of the ducts. This can happen for several reasons: High humidity levels: High humidity in your home or the area surrounding your ductwork can cause condensation to form on the cool surface of the ducts, especially during the summer months when your air conditioner is running. Ensure proper ventilation and consider using a dehumidifier to reduce humidity levels in your home. Poorly insulated ducts: If your ductwork is not properly insulated, the cool air passing through can cause the ducts' surface to become cold, leading to condensation formation. Inspect your ductwork for adequate insulation and add or replace insulation as needed. Contact Martino HVAC for assistance with duct insulation. Leaky ducts: If your ductwork has gaps or leaks, cool air can escape and cause the surrounding air to cool down, resulting in condensation on the ducts. Inspect your ducts for leaks and seal them using appropriate duct tape or mastic, or have Martino HVAC professionals inspect and repair your duct system. Inadequate air sealing: If there are gaps or openings around your home's windows, doors, or other areas, humid outdoor air can enter your home and cause condensation on your ductwork. Seal any gaps or openings to prevent humid air from entering your home. Oversized or short-cycling air conditioning system: If your air conditioning system is too large for your home or short-cycling (turning on and off frequently), it may not effectively remove humidity from the air, leading to condensation on your ductwork. Consult with Martino HVAC to determine if your system is appropriately sized for your home and to address any short-cycling issues. If you're experiencing ductwork sweating or dripping water and cannot identify the cause, it's essential to contact Martino HVAC for a professional assessment and any necessary repairs. Addressing the issue will help prevent potential damage to your home and maintain a comfortable indoor environment.
