Why Is My Air Conditioner Leaking Water?

There are times in a person’s life when a feeling of sheer panic overtakes you. When someone you love gets injured. When a driver ahead of you slams on their brakes, causing a chain reaction of brake slamming. And when you find a puddle of water near your air conditioner.

You know it’s true. It’s okay to admit it. When you see a puddle of water anywhere near your air conditioner, all the hot days from your past flash before you. Sweat beads roll down your forehead, just thinking about trying to make it through this upcoming Arizona summer without a working air conditioner.

And because if you didn’t have bad luck, you wouldn’t have any luck at all, you have convinced yourself this water puddle means you’re going to have to replace the whole air conditioner with money you don’t have.

Okay, so before we let anxiety get out of control, we want you to know it might not be that bad.

There are some common, very fixable problems that could be causing your air conditioner to leak water. Keep reading to find out what they are and what you can do to stop them.

Dirty Filters

For your air conditioner to work, it needs clean air filters that don’t restrict the flow of air. Otherwise, the air that hits your evaporator coils will freeze. Once it starts to melt, water will drip. The size of your water puddle will be based on how much moisture was frozen on the coils.

This leak problem can be avoided by simply changing or cleaning your air filters based on the recommendations of the appliance manufacturer. Typically, changing air filters should happen once every two or three months. You should check the status of the filter every month since the amount of buildup can vary based on the seasons.

This is a chore that doesn’t require the help of a Phoenix-based HVAC professional unless the water leak continues even after you have changed the filter.

Damaged Drain Pan

Drain pans, drip pans, condensate pans are different names for an item that has one job, to catch the condensation that forms. It’s placed under the coils, catching water, sending it down a drainpipe that leads to the outdoors.

If there is something wrong with your drain pan, like a crack or clog, then water will not be able to flow into the drain pipe. It will back up and overflow into your home.

Replacing a drain pan can be easy for an experienced DIYer. However, others should call a local licensed Arizona air conditioning repair company for assistance.

A drain problem from the pan can also be a problem with the drain pipe.

Clogged Drain Pipe

Any pipe can get clogged. Some are clogged by dirt and debris, while others are obstructed by the buildup of sediments from homes that have hard water. Bacteria, mold, and mildew can even clog some pipes.

When a pipe is clogged, this means it is closed and can’t allow water to pass through. If the water from your pan can’t get through the pipe, it will stay in the pan and eventually overflow, causing water puddles.

Some YouTubers want to teach you how to clean your drain lines with vinegar and water, and this may work. Just keep in mind this is an expensive unit. Calling an AC expert near you, like Integrity HVAC, is recommended.

Also, you may find your drain pan and pipe problems may be related to the condenser pump. This is the part that pushes the water out of the pipe when the water rises in the pan. A sensor triggers it when to shut on to force the water down the line and outside. If the pump is broken, this can’t happen.

We can help you figure out the actual cause of the problem so you can make the right choice when it comes to repairing.

Other Reasons for Leaks

Refrigerant leaks cause some water issues. Refrigerant is what makes the magic happen. It turns the hot air into cold air.

Leaks may also happen because the installation of your air conditioner was not done correctly. Even a slight tilt or uneven surface can cause the system to leak. To avoid any of these problems, call a Phoenix-area HVAC team who can provide maintenance and prevention services, so you never have to experience the fear of going without air conditioning, ever again.
