Is Your AC Leaking? 5 Possible Causes and Fixes Skip to main content

The first air conditioner was built in 1902 to protect paper and ink at publishing companies. Models created for home use were released shortly afterwards, with prices ranging between $10,000 and $50,000.

Luckily, they’re now much more affordable. Still, though, they seem to run into a plethora of issues. One example is AC leaking. Considering the current weather in Conroe, the last thing you want is a malfunctioning air conditioner.

So, how do you prevent those nasty puddles from forming under your unit? For an idea on 5 causes and how to fix an AC leak, read ahead!

Evaporator Coil

Evaporator coils are responsible for removing humidity and heat via refrigerant. Sometimes, though, insufficient airflow or lower temperatures can freeze these tubes. This can accelerate condensation and form ice, which might start dripping in unintended areas.

Check if this is the case by opening the blower door. If you see ice or water dripping along the coils, you’ve found your problem! Now just regulate airflow or add refrigerant.

Poor Installation

Poor installation can cause AC leaking. There are so many variables in this case, though, that it’s hard to pinpoint the issue. Most of the time, an incorrect installation of the condensate trap prevents proper drainage.

You’re better off calling a technician. With or without assistance, the solution is to reinstall the condensate trap or buy a new one.

Drain Pump

The drain pump pulls water from the overflow pan. If this apparatus malfunctions, the pan overflows. It’s easy to confuse this problem with a clogged drain line.

In this case, again, you’re better off reaching out to a service technician. However, the solution involves repairing the drain pump or purchasing a new one.

Drain Line

A clogged drain line results in a leaking overflow pan. The most common culprits are mold, dirt, and other particles.

To check if this is the case, ensure that your pump is working properly. Then, empty the overflow pan and refill it with water. If you notice the levels dropping, then it’s not the drain line.

A common solution involves cleaning these pipes with vinegar. However, it’s highly recommended to reach out to a professional. They’ll usually use special equipment or replace the drain line outright.

Overflow Pan Crack

This is the simplest problem involving AC leaking. The overflow pan can take damage, on rare occasion, resulting in a crack along the bottom. What follows is an easy to repair leakage.

You can use specialized tape or adhesive to seal the crack. However, again, it’s better to contact a technician. It’s uncommon that they’ll seek to replace the pan, so expect a simple fix.

The Best Way to Solve your AC Leaking

Some of the problems that cause AC leaking have a homemade solution. It’s not always necessary to contact a professional for AC unit fixes.

However, a Conroe technician is preferable for many reasons. First of all, they can quickly assess the situation to find what’s causing the AC leaks. Next, they’re also knowledgeable on the necessary repairs.

Finally, beyond diagnostics and fixes, they know how to stop an AC from leaking. So, if you’re unsure of what to do, reach out for assistance. A solution is one phone call, email, or text message away!
