Roughly 90 percent of issues with air conditioning systems relate to water leakage. Even if these leaks are small, if you don’t address the situation quickly it could eventually lead to significant damage to your home and the unit itself.
As a homeowner, are you aware of the causes that trigger air conditioner leaking incidents?
Understanding How Your Air Conditioner Works
First, you should know that every AC unit has an evaporator coil. The purpose of this element is to cool the warm air blown over it. Essentially, this is likely to trigger condensation on the coil, much like the way water droplets form on a cold glass of water in a warm environment.
Eventually, the moisture on the coil ends up dripping into a drain pan, down a condensate drain line, and then end up in your home. So, what are the primary causes behind an AC leak?
Clogged Condensate Drain Line
Problems with the condensate drain line are quite common. Therefore, you should address them as soon as you notice air conditioner leaking water. The drain line represents the first suspect when you’re dealing with water leaks. In the event it becomes clogged due to debris and dirt, the clog will lead to leaks or ruptures of the line. Another common scenario is that the drain line isn’t securely connected. This could happen if the installation wasn’t done carefully. Due to vibrations, the drain might be loosened, which will inevitably lead to the AC leaking water in your home. Now, considering that the drain line has been clogged with dirt and debris, unclogging the line is a must. It’s best to request the assistance of a professional before the situation becomes worse.
Pan and Pump Issues
If your air conditioning system is situated in a basement, this could lead to additional issues. The drain line is likely to empty the condensate into a drain pan. Then it’s redirected by a condensate pump. If this type of setup sounds familiar to you, then you’re most likely to experience an AC leaking water, and this can happen in different ways. The most common is the following:
- The condensate pump has broken down, leading to the overflowing of the pan, or
- The older drain pan has developed rust while having developed holes and cracks
Dirty Air Filter
Another common cause of an AC system that leaks water is a dirty air filter, which will block the airflow over the evaporator coil. If this occurs, the evaporator coil will imminently get too cold, and in some cases may freeze over. When the melting process starts, it will drip a significant amount of water that’s nearly impossible for the pan to handle. Be careful with the air filter. Change it if you see signs that it’s dirty. As a rule of thumb, the air filter should be changed every 1-3 months, depending on the season.
Just like a dirty air filter will jeopardize the performance of your air conditioning system, the same can be said about low refrigerant. This will diminish the pressure in the system and the evaporator coil will
