Lamens Terms: Because it is cold and like a cold glass of tea on a hot summer day, the moisture in the air condensates on the cold surface.
Technical: Because the surface of the duct is below the dew point temperature of the ambient air surrounding it, causing an accumulation of condensation on the surface itself. The room needs to be conditioned closer to the relative temperature of the air inside the duct (Usually with 15-25 degrees) to avoid the laws of enthalpy from taking place.

What is condensate blowoff?
Condensate blowoff is water that condenses on an evaporator coil, is blown off the coil, and then carried a short distance down the duct by the velocity of the air through the coil.
What are the differences between flex duct and rigid duct, and which one is more suitable for my HVAC system?
Flex duct is a flexible, accordion-like duct made of plastic and wire, while rigid duct is a solid, inflexible duct typically made of metal. Flex duct is easier to install in tight spaces, but can be less efficient and more prone to damage. Rigid duct is more durable and efficient, but harder to install in tight spaces. The choice between the two depends on your specific HVAC system and installation needs. Consulting with a professional HVAC technician can help determine which type of duct is more suitable for your system.
What are the primary uses of pinstripe tape?
Duct tape is a great to to seal off a HVAC duct. The tape is strong and works effectively for your needs. Duct tape can offer a tight seal for your duct.
What is the purpose of a start collar in HVAC systems?
