Homeowners are often frustrated about the water leakage problem in their air conditioners. In this article, I’ll tell you about the 5 reasons behind AC water leakage problem and ways to repair it.
5 Reasons behind AC Water Leakage
1. Your Evaporator Coil is Frozen
The frozen evaporator coil is one of the main reasons behind air conditioner water leakage. Frozen evaporator coil can be caused by a number of reasons like – dirty air filter, low refrigerant level, broken blower motor, a dirty coil, etc. But among these, low refrigerant level is the most common.
Your air conditioner refrigerant absorbs the heat from your room and releases the heat to the outside unit. That’s how you get your desired cooling from your air conditioner. But when your refrigerant level gets low, your air conditioner won’t be able to absorb heat, and you won’t get any cooling from your air conditioner.
As refrigerant flows throw the evaporator coil, lack of refrigerant level freezes the evaporator coil, and you’ll notice water dripping. If your air conditioner has a frozen evaporator coil, turn off the system and call an HVAC professional in your house. He or she will check the refrigerant level in your air conditioner and refill it.

These are the three DIY easy steps to clean your clogged drain line. However, if your drain line is still clogged, you should call an HVAC professional.
3. Dirty Air Filter
Dirty air filter blocks the airflow in your air conditioner. As a result, your evaporator coil gets cold and starts freezing. After a certain time, ice starts to melt, and water starts dripping from your air conditioner.
To solve this problem, you’ll have to change your air filter regularly. It’s recommended that you should change your air filter every 3 to 4 months. However, this duration depends on your usage and pollution level in your area.
As the air quality in Dallas is poor compared to other cities in the US, you should change your air filter every 60 days. Again, if you use your air conditioner regularly, you may have to change your air filter more frequently. If you’re still confused about how frequently you should change the filter, you can contact an HVAC professional. He or she will suggest the ideal time to change an HVAC air filter.
4. Cracked Drain Pan
Overflowing or cracked drain pan can cause air conditioner water leakage problems. You’ll find the drain pan underneath the indoor air handler. To clean the cracked drain pan, you’ll have to use a wet dry-vac. While cleaning the cracked drain pan, inspect the corners and edges of the drain pan with a flashlight. The best way to repair the cracked drain pan is by replacing the damaged drain pan with a new one. However, you can use a water sealant if you want to repair the cracked drain pan temporarily.
5. Air Leakage
If your house isn’t properly insulated, warm air from outside will enter your home. As a result, moisture will get condensed with the cold air inside the air conditioner, and you’ll start noticing water leakage in your air conditioner.
To solve this problem, you’ll have to make sure that your home is properly insulated. Also, while using the air conditioner, make sure that all the windows and doors are properly closed.
