There’s nothing more than having your air conditioner leaking water all over the place. Not only does a situation like this leave you feeling hot and sticky, it’s also a hassle. Take advantage of the tips below, and get you’ll get your leaky air condition repaired in no time.
When an air conditioner is leaking water, there are several reasons why this could be happening. It’s important that you diagnose your system as soon as possible, so further damage doesn’t result. Extended dripping can lead to electrical problems, mold issues and property damage. However, before you begin to diagnose your unit, it’s essential that you turn off the power unplug it. This will prevent the system from accidentally turning off.
How does my air condition system create moisture?
Before you pull off the face cover on your unit and dig in, it’s important to understand how water is formed in the inside of your air conditioning system. On the interior of your unit, you’ll see an evaporator coil. What does this do? As warm air travels over the top portion of the evaporator coil, it lowers the temperature of it. As a result, condensation begins to accumulate on the coil. A perfect example of this is like when moisture forms on the outside of a cold glass of lemonade on a sunny afternoon.
When the water drips from the evaporator coil, the droplets fall into a drain pan and then down through a condensate drain line. This condensate drain line runs to the outside of your home and disposes of the water. Now that you have a basic understanding of your system, equip yourself with a flashlight and start removing the outside cover. Some air condition covers snap on while others are screwed in. It’s highly recommended that you read the owner’s manual for precise instructions on removing this.
Defected overflow pan
One of the most common reasons why air conditions tend to leak water is due to a faulty overflow pan. Overtime, holes and cracks can form allowing water to seep out. Start by using your flashlight to inspect the pan. Make sure you check the corners really good in addition to the sides of it as well.
If your overflow pan does have small holes or cracks, you can use epoxy glue to close them up. However, if you do patch up these holes and cracks, just know that you will have to replace the overflow pan in the near future. This is only a temporary fix. It’s best to visit your local home improvement store for a new overflow pan and fix it as soon as possible.
It’s important to note that there are two separate drip pans. The first one is located just below the evaporator coil and the second one is positioned below the unit and is easily removable. If this drip pan becomes holey or cracked, you’ll notice leaking water from the bottom of your unit.
To replace the overflow drip pan, located underneath the evaporator coil, you’ll need your replacement, a wrench and some plyers.
- Make sure your unit is turned off and disconnected.
- Locate the hatch the protects the evaporator coil and remove it.
- Carefully use your plyers or your wrench to disconnect the unit’s drain line.
- Unscrew or unclip the pan. If the pan and the coil are one piece, you’ll have to replace the coil as well.
- Replace the overflow pan and reconnect it and the drain line.
- Reconnect your power.
It’s important to note that the process of replacing the lower drip pan will usually be the same the process for the top drip pan.
Clogged air condition filter
Another reason why your air conditioner unit maybe leaking water could be due to the unit’s filter. If the filter is filthy or has visible dirt, it’s best to change it as soon as possible. The reason why a clogged filter causes waster to drip from your air condition is because when the filter becomes dirty, ice begins to form on the evaporator coils. As a result, your unit will drip when the ice begins to melt.
Disconnected drain line
It’s important to make sure that the individual who’s installing your air conditioning system does it correctly. When a unit is installed incorrectly, several problems can result. One of these problems includes not having your drain line tightened appropriately. Overtime, this line can become loose and eventually disconnect resulting in your air conditioner leaking from inside.
Running your air conditioning when temperatures are dropping can cause dripping and possible damage to the unit itself. The coils in your air conditioning system will begin to ice up if you’re running the unit when it’s below a temperature of 60 degrees Fahrenheit outdoors. Instead of running your air condition when it’s cool outside, it’s better to crack a window and let some fresh air into your home.
The condensate drain line is clogged
A clogged condensate drain line can also result in an air conditioner leak. Overtime, Algae, rubble and fungi will accumulate inside your condensate drain line and cause a blockage. When your condensate drain line becomes blocked, your overflow pan will literally overflow.
To remove the blockage, you have a few different options. One involves using vinegar and the other involves a dry/wet vacuum. To remove the blockage follow these steps:
- Near the drain pan, you’ll find a PVC pipe. This pipe will have a little cap on top. Unscrew the cap and take it off.
- Take 6 ounces of vinegar and pour it down the pipe. This will help remove any blockages like fungi or algae. This should be completed every couple months.
- If this doesn’t remove the blockage, use the wet/dry vacuum.
- To use the wet/dry vacuum, find your home’s outdoor condensate drain line. This line is usually located by your condenser unit.
- Connect the wet/dry vacuum with the attachment. This attachment can be purchased at most home improvement store.
- Turn your dry/wet vacuum on.
If your air conditioner is still leaking water, you will want to call a professional and have them take a look at it.
