Condensation commonly occurs when a vapor is cooled. Water vapor from air which naturally condenses on cold surfaces into liquid water is called dew. Water vapor will only condense onto another surface when that surface is cooler than the temperature of the water vapor, or when the water vapor equilibrium in air, i. e. saturation humidity, has been exceeded. When water vapor condenses onto a surface, a net warming occurs on that surface.
the air inside u is warmer than the air outside, that is called condinsation when they mix.
I think it is the condinsation going on, condinsation: condinsation is when fall turns into winter, it removes heat and freezes the pond, spring causes it to melt, summer cuases it to start eveporating, and fall cuases to condence it.
Return ducts are under less pressure, but they need to move the same amount of air, so they must be larger.
Ductless air conditioners are not better than ones with ducts. The reason why ductless air conditioners are not better than ones with ducts is that they don't remove the hot air as well.
AC flex ducts can fill with water due to condensation forming on the duct surface from temperature differences between the cold air inside the duct and the warmer air outside. Poor installation, insulation gaps, or clogs in the ductwork can exacerbate condensation issues. Additionally, high humidity levels or improper drainage can contribute to water accumulation in the ducts.
Air flows in a furnace from the return ducts into the furnace, where it is heated and then pushed out through the supply ducts to heat the home.
Insulation in air ducts is typically installed by professionals during the construction or renovation of a building. It is usually in the form of specialized insulation material wrapped around or lining the ducts to help maintain the desired temperature of the air flowing through them.
It is possible to buy an air conditioning duct separately from an air conditioner. A great place to start looking is at www.ductworks.net/This site has a wide variety of air conditioner ducts.

There are three main types of air ducts: sheet metal, pre-insulated, and flexible duct work. Sheet metal air ducts can be made of galvanized steel or aluminum, and may be insulated inside or outside with fiberglass. There are pre-insulated air ducts, which are relatively inexpensive to install, made of fiberglass duct board, polyurethane foam panels, or phenolic foam panels. Air ducts can also be flexible ducts, made of flexible plastic over a wire coil.
The airflow on a furnace is typically directed from the return air ducts to the heat exchanger and then out through the supply air ducts to distribute heated air throughout a building.
Air ducts in a house should be cleaned every 3-5 years to maintain good indoor air quality.
