Is your AC unit leaking water? Don’t panic, there is probably an easy fix! However, it’s important to address this problem as soon as possible to prevent any further water damage or costly repairs. In this blog post, we’ll discuss the possible causes of an AC unit leaking water and provide some troubleshooting tips to help you stop the leak and keep your home cool and comfortable. So, let’s dive into the world of AC unit maintenance and fix that pesky water problem once and for all.
Common Causes of AC Unit Leaks
The following are the most common causes of air conditioner leaks.
1. Clogged Condensate Drain Line
One of the most frequent causes is a clogged condensate line. Over time, dirt, dust, and debris can accumulate in the drain line, causing a clogged drain line. This blockage prevents water from draining properly, resulting in overflow and an AC leak.
2. Frozen Evaporator Coil
Another common cause is a frozen evaporator coil. When the coil freezes, it can lead to excess water that leaks from the unit as it thaws.
3. Damaged Drain Pan
Your drain or drip pan collects water from the condensation drain line. If the drain pan is cracked or has holes, water can escape and cause water dripping from the pan.
4. Low Refrigerant Levels
In some cases, AC unit leaks can also be attributed to low refrigerant levels. When there is not enough refrigerant in the system, the evaporator coil can freeze and produce excess water. It’s important to address a refrigerant leak promptly to prevent further leaks and damage to the unit.
5. Improper Sizing of the AC Unit
Finally, improper installation or improper sizing of the HVAC unit can also result in leaks. If the unit is not installed correctly or if it is too large or small for the space, it can lead to water accumulation and leakage.
Steps to Troubleshoot Your Leaking AC Unit
Now that you understand why your AC unit might be leaking water, it’s time to troubleshoot the issue. Here are a few steps you can take to get to the bottom of the problem:
Check the condensate drain line
Start by inspecting the drain line for any clogs. If you notice any debris or dirt, use a wet/dry vacuum or a pipe cleaner to clear it out. Make sure the drain line is free from any obstructions to allow the water to flow properly.
Clean or replace the air filter
A dirty air filter can restrict airflow and ice forms on the evaporator coil. Check the air filter and clean or replace it if necessary. Once the frozen coil melts, the water leakage should stop. Although you will end up with a puddle of water from the melting, but that’s normal.
Inspect the drain pan
Take a look at the drain pan underneath the evaporator coil. If you notice any cracks, holes, or damage where it’s dripping water, it’s important to replace the drain pan as soon as possible. A damaged drain pan can lead to water leakage and potentially cause further damage to your AC unit and cause mold growth.
When to Call a Professional for Your AC Water Leak Issue
While troubleshooting and fixing minor AC issues can often be done on your own, there are times when it’s best to call an HVAC professional to help find the cause of the problem and repair it. If you don’t see a simple solution, it’s time to reach out to an HVAC technician. Also, if you’re unsure about any of the steps or uncomfortable performing them yourself, it’s always best to seek professional assistance. Remember, AC units are complex systems, and attempting to fix a problem without the right knowledge and experience is not a good idea and can lead to further damage or even personal injury.

Preventive Measures to Avoid Future AC Leaks
Preventive Measures to Avoid Future AC Leaks: Now that you’ve fixed the water leak in your AC unit, it’s essential to take preventive measures to ensure it doesn’t happen again in the future. Here are a few simple steps you can take to avoid AC leaks:
Schedule regular maintenance for your AC unit, ideally twice a year, to ensure it is clean, functioning properly, and free from any potential issues. A professional technician can inspect and clean the condensate drain line, evaporator coil, and other components, preventing clogs and freezing.
Regularly replace air filter
Make it a habit to clean or replace your air filter every one to three months, depending on usage, to ensure proper airflow and prevent water accumulation caused by a clogged air filter.
Keep the area around your AC unit clean
Clear any debris, leaves, or vegetation from around your outdoor unit. This helps to maintain proper airflow and prevents clogs in the condensate drain line.
Maintain proper humidity levels
Excessive humidity can contribute to the freezing of the evaporator coil, leading to leaks. Use a dehumidifier in your home if necessary to keep the humidity at a comfortable level.
