Is Your AC Leaking Water Inside Your Overland Park Home: Here's What To Do

Walking into your home in Overland Park and finding a puddle of water under your AC unit is never a good sign, especially in the middle of summer. When temperatures rise, your air conditioning system works overtime to keep your home cool, but that extra stress can reveal hidden problems. One of the most common issues homeowners run into during this time of year is water leaking from the indoor AC unit. This mess doesn’t just lead to stained walls and ceilings. It can spread quickly and bring mold, mildew, and additional damage you might not notice until it’s too late.

A leaking AC system is usually a sign that one or more components aren’t working the way they should. The cause might seem small at first, but if left unchecked, it can turn into a more expensive problem. Water damage tends to creep into flooring or behind sheetrock and can weaken your home’s structure over time. That’s why it’s important to act quickly. The sooner you identify what’s causing the leak, the easier it will be to get it fixed and prevent it from happening again.

Common Causes Of AC Water Leaks Inside The Home

Knowing what’s behind the puddle on your floor can help you focus on the right fix. There are several possible reasons your AC may be leaking water indoors, and most of them start with simple malfunctions that impact how the system handles condensation.

1. Clogged Condensate Drain Line

Over time, algae, dirt, and debris can block the drain line that’s supposed to carry moisture outside. When this happens, that water backs up and spills into your home instead.

2. Dirty Air Filters

When filters get too dirty, they block airflow. That can cause parts of your system to freeze up. Once the system shuts off or warms up, that ice melts, leading to water dripping from places it shouldn't.

3. Low Refrigerant Levels

Refrigerant helps cool the air and keep moisture under control. If it runs low, it can cause your coil to freeze, eventually melting into an unexpected leak.

4. Faulty Condensate Pump

Some homes rely on a small pump to move collected water out of the house. If that pump fails, water has nowhere to go and starts pooling around the unit.

5. Improper Installation or Lack of Maintenance

If the unit wasn’t installed with the right tilt or lacks proper support underneath, water may not drain the way it was designed to. Also, without regular maintenance, wear and tear adds up and drainage becomes less effective.

For example, we recently checked out a home in Overland Park where water had been dripping from an upstairs closet. Turned out, the AC unit’s drain line had been blocked for weeks, and the homeowner didn’t know until the ceiling below started showing water spots. By that point, there was already mold on the drywall and water damage in the floorboards. This kind of leak can escalate quickly, so knowing what to watch for goes a long way in catching problems early.

Immediate Steps Homeowners Can Take

When your AC starts leaking water indoors, the first thing to do is act fast. Water damage doesn’t need much time to spread, and ignoring it just makes things worse. While this isn’t a problem you want to fix on your own, there are a few things you can do right away to reduce the risk and figure out what’s going on.

Here’s a list of simple actions you can take:

- Turn off the AC. This halts the flow of water and gives you time to assess the situation without making it worse.

- Check your AC filter. If it looks dirty, change it. Blocked airflow can contribute to ice buildup that melts into leaks.

- Look at the drain line. If you see water not running through the drainpipe, it might be clogged.

- If you feel comfortable, use a wet/dry vacuum on the outside end of the drainpipe to try and remove any blockage.

- Pour a small bleach-water solution down the drain line to help remove sludge from the tray and line. Do this only if you fully understand where to pour it and can access the drain tray safely.

- For systems with a condensate pump, listen for it turning on. If it’s silent or makes strange noises, it may not be working properly.

These steps won’t fix the core issue, but they can help stop additional damage while you wait for our technicians to arrive. If you’ve taken these measures and the problem comes back, that’s a clear sign the system needs more involved work.

Why Professional Inspection And Repairs Are Essential

What might start as a small leak often points to a bigger issue hiding inside your AC system. Fixing the symptom isn’t enough. Our professionals are trained to go deeper, not just stopping the water but finding out why your unit is leaking in the first place.

When our technicians arrive, you can expect a full inspection of the entire condenser, coils, and drain paths. If parts are clogged or damaged, we’ll spot it. If refrigerant levels are low, we’ll check pressures and identify potential leaks in the sealed system. These types of issues require specialized tools and training. It's not something that can be fixed by cleaning a filter or unclogging a pipe alone.

Our team also handles proper draining and leveling issues that cause water to back up or flow in the wrong direction. Sometimes, the fix isn’t obvious, like a poorly seated drain pan or a sagging drain line that collects water instead of draining it. We address those root causes so you’re not just cleaning up the mess but stopping it from happening again next week.

Regular service helps too. When your system is inspected on a consistent schedule, small problems are caught before they reach the point of damage. Our professionals look for signs of buildup, wear, and unseen failures that often lead to indoor leaks. They’ll clean components thoroughly, realign any sections out of place, and make sure your AC system is ready to handle the hot months ahead.
