Air conditioners give off water as part of their dehumidifying process. And since this water is of no use to an air conditioning system, it is usually drained through a system of small tubes. These tubes empty the water into a special pump called a condensate pump, which then pumps the water out of the air conditioning unit.
Air conditioner water leaks usually occur when there is something interfering with the drainage process. Therefore, if your air conditioner is leaking, there might be a problem with your unit's emptying tubes, its condensate pump or its check valve. Here are tips to help you get rid of air conditioner moisture leaks.
The simplest and most common explanation for a leaking air conditioning unit is torn tubes. When this happens, every time the unit tries to drain any condensation from its system, water leaks from the holes or tears in the tubing system.
Fixing this problem is simple. All you have to do is to buy tubing from a nearby HVAC supply shop and replace the torn tubes.
Sometimes, problems with the tubing system do not arise from tears but from clogging. With time, dirt may collect inside the tubes and thus blocking them. It may also be a case of algae growth inside the tubing system.
To unclog the tubes, simply blow through them. And if that doesn't work, running a wire through the tubes will. However, this will not be enough if it is an algae problem because algae can always grow back. Therefore, in addition to wire-running, you will also have to run a diluted bleach solution through the tubing system.
The water-draining process of an air conditioner usually kicks in only when the water collected has reached a certain level. And to ensure that this happens, the unit usually relies on a ball-float that rises as more and more water is collected. This floating ball is what acts as the on/off switch for the draining pump. If this ball gets stuck, then the water-draining process cannot proceed as designed. This can cause flooding inside the system and hence the leaks.
To fix this problem, you will need to loosen the ball inside the check valve. Make sure that you clean it before screwing it back and if the problem persists, you may have to replace the check-valve.
A broken pump
A condensate pump plays a central role when it comes to getting rid of moisture residue from an air conditioning unit. When it breaks down, the whole process comes to a standstill, causing water leaks. When this happens, it is usually advisable to call an air conditioning repair technician.Share
