This article is for those of you who have an air conditioner and want to know more about the water that may be collecting on it. Aircon condensation can be a problem if you don’t deal with it quickly, so read on for some helpful tips!

What Is Air Conditioner Condensation?

Condensation mainly occurs when warm, humid air comes into contact with something cold. You may notice some form of condensation in and around the AC vent and the air ducts. Condensation may also occur when moisture from the AC unit is exposed to the cold ducts of the same. The condensed air turns into water droplets that then drips down the AC unit or vents.

What Causes Aircon Condensation?

Bacteria buildup in the air conditioner is one of the most common causes of aircon condensation. The bacteria create a clog inside the condensation pan, causing water to collect and fill up over time.

The air conditioner also sucks warm, humid air indoors then blows it over frozen pipes and vents.  With the evaporator coils colder than the air around, any moisture coming into contact with these coils condenses almost instantly.

If left unchecked, the condensed water accumulates with time creating a pool, then drips off the air conditioner.  The drain line allows water to collect in the drip pan, which should be drained off properly. Failure to do so in time causes the water to overflow, putting other parts of the aircon at risk.

A dirty air filter is known to cause excessive condensation in ACs.  It is for this reason manufacturers and experts advise us to service and maintain our units regularly.  This entails cleaning the air filters or replacing them with new ones.  Dirty air filters block the smooth flow of air from the unit to the ducts. This at times causes the evaporator coil to freeze up, increasing the risk of warm air condensing and water accumulating in the evaporation pan. Too much water in the evaporator pan then starts leaking out of the unit.

Causes of Condensation in Aircon Trunking

Aircon trunking can be defined as the outer casing that protects internal elements from external elements. It thus covers everything from electrical cables, PVC pipes, copper conduits, and other aspects of the AC.

The aircon conduit is also designed to help protect your home, especially the walls, from damage. An intact aircon trunking thus helps give your air conditioner more life while reducing servicing and maintenance costs.

It is quite normal for condensation to occur on/in the aircon trunking. This happens as warm air comes into contact with the cold surface of the case, forming water droplets.  However, the trunking is designed to drain the moisture trapped to the condensation line down the backup drip line. This reduces the risk of water pooling and damaging electrical components in the unit.  Most aircon systems will handle trunking condensation automatically.

Poor insulation, trap floor blockages, and a poorly installed trunk could make the situation worse. A blocked floor trap means condensed water won’t drain off, hence could accumulate to drench components in the unit. Dripping water from the same could also cause severe damage to your home as well.

How to Prevent Aircon Condensation?

First, make a habit of cleaning and replacing air filters as required. Second, make sure the drip pan is connected to the drain tube and that the pan is slightly tilted to prevent pooling. You might also want to add more insulation to the outdoor unit, especially around the existing ductwork.
