Your air conditioning (AC) system should always be able to get rid of the water it draws in from the air. This is the function of the condensate drain line and its related parts. Your AC will suffer water-related damages if something happens to this part of the system. Here are three examples of drainage issues that may plague your AC:
Mold growth may not seem like a drainage problem, but it is. This is because mold thrives in moist places. Therefore, if your AC system is experiencing drainage problems, and it is constantly wet, you risk having mold in the system. Don't forget how dangerous it is to have mold in your AC system; it may get distributed with the conditioned air and cause respiratory ailments in your household.
The drain tube (from the AC pan) is a common site for mold growth, especially during the summer when you need the cooling power of your AC. Therefore, ensure there is no obstruction in this part of the AC (obstruction may interfere with drainage) and that the drain is always clean.
Blocked or Dry Traps
The drainage system of your AC has a U-shaped trapped, just like the one below your kitchen sink. The trap may look insignificant, but it plays an essential role in the drainage and hence overall health of the AC. The trap prevents air from moving in or out of the air handler when the AC is running. It must be able to do this while still allowing the condensate to move from the pan.
If the trap doesn't do this, moisture-laden air will move through it and cause condensation issues when it meets the cold sections of the AC system. At the same time, a malfunctioning trap can draw in air and prevent the drain pipe from draining, causing it to overflow and cause the related water problems. For this not to happen, the drain trap must always be dry and unobstructed; regular cleaning will help with that.
Drain Line Leakage
This problem arises if the condensate drain line gets punctured or something obstructs the line. Either of those can cause a leakage or overflow of the condensate pan. The resulting problems include mold growth and damage to different parts of the AC. Again, simple maintenance and cleaning of the AC will prevent this problem.
As you can see, drainage issues can cause serious problems for your AC. Luckily, you can prevent most of them by regularly maintaining your AC system. Consult a technician if you are dealing with drainage issues despite regular cleaning of the unit and visit a site like http://www.coeheatcool.com.
