Reasons Why Your AC is Leaking Water

If you’ve noticed water leaking from your AC unit, it’s important to find out why and how to fix it. When your AC is leaking, it can be caused by several different things. And if left untreated, these AC leaks can lead to further damage and costly repairs. With the heat wave we’ve been having this summer, your AC has probably been working pretty hard, and the last thing you want is for that to stop! In this blog post, we’ll take a look at some common reasons why your AC is leaking and how you can fix them.

How Water Forms in Your AC Unit

Many air conditioning systems contain both indoor and outdoor units, which are connected by a series of copper pipes. These pipes carry freon, a refrigerant that helps to cool the air inside your home. As the Freon passes through the indoor and outdoor units, it absorbs heat from inside your home and releases it outdoors. As the hot air moves over the coil, condensation starts to form. This is because the Freon is absorbing heat from inside your home, which causes it to cool down and turn into a liquid. The condensation then drips down into a drain pan, where it’s collected and eventually drained out of your AC unit.

However, if there’s a problem with your AC unit, this process can be disrupted, and water can start to leak from your AC. So, what are some of the common reasons why your AC is Leaking?

Reasons Your AC is Leaking

When it comes to determining why your AC is leaking, there are a few things that could be happening.

Your Condensate Drain Line is Clogged

If you notice your AC is leaking inside, a clogged condensate drain line is most likely the culprit. Your AC unit produces a lot of condensation, especially during the hot summer months. This condensation collects in the drain pan and is then drained out through the condensate drain line.

However, over time this line can become clogged with dirt, dust, and other debris. When this happens, water will start to back up and eventually leak out of your AC unit. If you think your condensate drain line is clogged, the best thing to do is contact a professional AC repair technician. They will be able to clean out your line, fix what is causing the leak and get your AC up and running again in no time!

The Filter is Full of Dirt and Debris

We’ve mentioned in other blogs just how important it is to change your air filters regularly. This is because a dirty air filter can cause all sorts of problems for your AC unit, including AC leaks. A dirty filter will also make your system work harder than it needs to which can result in possible damage.

When your air filter is full of dirt and debris, it restricts the airflow to your AC unit. When air is blocked, it can cause the evaporator coil to freeze, which will cause water to start leaking from your AC.

When the frozen coil melts, the water can cause your drain pan to overflow, so it is important to keep a close eye on your filters.

If you notice that your AC is leaking and you haven’t changed your air filter in a while, be sure to do that as soon as possible!

Your AC Unit is Overheating

Another common cause reason behind why your AC is leaking can be overheating. When your AC unit overheats, the Freon can start to expand and leak out of your AC. This is usually caused by a faulty compressor or an issue with the AC’s electrical components.

A Rusty or Damaged Drain Pan

Another thing that may be causing your AC to leak is a rusty or damaged drain pan. Over time, the drain pan can start to rust and eventually break. This will cause water to start leaking from your AC unit.

Your AC Doesn't Have Enough Refrigerant

Your AC leaking can also be caused by not having enough refrigerant. As the volume of refrigerant gets lower, the pressure inside your AC system begins to lower, causing your evaporator coil to freeze.

If you happen to notice that your home isn’t getting as cold as it should, make sure to check your refrigerant levels. Other signs of low refrigerant levels include hissing or bubbling noises coming from your AC unit. If you’re not sure how to check your refrigerant levels, we recommend contacting a professional AC technician.

Other Reasons Behind AC Leaking

If you find your AC leaking, and none of the above problems are occurring, there are a few other potential causes to be aware of. One possibility is that your AC unit was not installed properly. If this is the case, water can start to leak from your AC unit as soon as it’s turned on. Another possibility is that there may be a problem with your ductwork. A hole or crack in your ductwork can cause water to start leaking into your home.
