Four Common Causes Of Condensation Problems On Ductwork

Having condensation on your ductwork is a serious problem. For example, the condensation can compress your attic insulation and make it less inefficient. It can also damage your ceiling and encourage mold growth, which is a serious health hazard. As usual with most problems, you need to know what causes condensation to help you prevent it. Here are four common causes of condensation:

AC Fan Malfunction         

The air conditioner's fans are supposed to cool the air so that it's roughly at the same temperature as the ductwork. If the AC fans are malfunctioning or damaged, and they aren't circulating the air as efficiently as they should, then the air around the room will be warmer than the ductwork. When this warm air rises and meets the cold surface of the ductwork, it will cool down and shed its water on the surface of the ductwork. This is the condensation that will cause the damages outlined above.

Inadequate Insulation

As previously mentioned, condensation occurs when moisture-laden warm air meets the surface of the duct works, which is at a lower temperature, and condenses. This means placing a barrier between the cold air in the duct works and the warm air can prevent condensation; this barrier is provided by the insulation. Therefore, if you are experiencing considerable condensation, then it's possible the insulation has either broken down or it's inadequate.

Inadequate Antifreeze

The antifreeze is the active agent that allows your AC to perform its cooling role. Therefore, the AC will lose its cooling capacity if the antifreeze level falls too low because there will be a heat exchange problem. Since your antifreeze isn't supposed to fall below a certain level, and its loss can cause serious problems, it's advisable to diagnose the cause of antifreeze loss (maybe there is a leak somewhere) as soon as possible.

High Humidity

Your ductwork will always have a little condensation, which shouldn't be a problem. It's when the condensation becomes too much that the problems start. For example, the condensation can be too much if the humidity in the house is too high, which may be the case if your home isn't properly sealed, you are storing firewood in the house, and you have plumbing leaks in the house, among other things.

Some of the condensation problems are things you can deal with on your own. For example, you may be able to reduce the humidity in your house without a professional's help. Most, however, require the intervention of a professional technician.
