Nothing is more frustrating than returning home from a long day to discover that your air conditioner is broken. Water leak from split AC can cause damage to your property in addition to making it uncomfortable. What is the source of the leaks, and how can you avoid them in the first place?

How To Solve Water Leak From Split Ac

A mini-split air conditioning unit users could find themselves in this situation. You can find yourself in this predicament if you have a mini-split air conditioner.

A mini-split air conditioner is a ductless system that links components via conduits rather than ductwork. If you use this type of air conditioner to heat and cool your home, you probably have several units.


There are a variety of reasons why air conditioner could be leaking, whether it was just installed or you've owned it for a long time;

  • Improper installation
  • Clogged drainage pipe
  • Dirt in the air filter
  • Low refrigerant/gas
  • Damaged drain pan

The cause of AC to leak is that water dripping from the main unit indicates that it is broken. The occurrence of such an issue could be caused by a variety of factors. Let's have a look at a few:

  1. Improper Installation

If your air conditioner has recently been installed and is leaking, the most likely cause is a bad installation. This indicates that neither the air conditioner nor the drainage pipes are proportionate. This causes the water to flow backwards from the drainage pan to the outflow. If the water cannot flow forward, it may flow backwards or remain at the same level. Ensure that the pipe is at a lower height than the main unit during the air conditioner installation so that the water can flow downwards to the drainage outlet.

  1. Clogged Drainage Pipe

Dirt and debris might clog air conditioning unit's drainage line. The condensate will be unable to flow out through the drainage system as a result of this. The water will overflow into the primary air conditioning unit if it can't flow outwards. AC will begin to leak water as a result of this. Make sure AC is cleaned on a regular basis. Calling for experienced service from Urban Company to service air conditioning machine is the easier option.

  1. Dirt In The Air filter

The debris that collects inside the air conditioning unit might clog the AC filters. This can obstruct airflow across the evaporator coils, causing the coils' temperature to plummet to dangerously low levels. In this case, ice forms over the coils instead of moisture, dropping an excessive amount of water into the drainage pan. The pan's capacity to hold the excess water is exceeded, causing the AC to leak water through the main unit. Cleaning the air conditioner on a monthly basis to remove dust and dirt.

Such small problems can be resolved with the help of an AC troubleshooting guide. The other option is to get your AC serviced and maintained by the professionals at Urban Company.

  1. Low Refrigerant/ Gas

When the refrigerant, also known as AC gas, leaks, it lowers the pressure inside the air conditioner. The evaporator coils freeze, resulting in a similar overflow of water in the drainage pan.

  1. Damaged Drain Pan

If your air conditioner is old, the condensate drain pan may be broken or rusted. Water will not gather in such a condition and will instead leak through the main unit.


A clogged drainage pipe is one of the most prevalent causes of a leaky interior air conditioner. Fortunately, that's also one of the most straightforward issues to resolve.


  • Phillips head screwdriver
  • Electrical tape
  • Bucket
  • Vacuum


Once you've gathered all of the necessary equipment, follow these steps:

  1. Turn the AC unit off
  2. Remove the filter
  3. Remove the plastic cover
  4. Locate the drainage pipe
  5. Use a bucket to drain the pipe
  6. Vacuum any excess dust
  7. Seal the joint back together with electrical tape
  8. Reassemble AC unit and turn it back on

Control your machine. If the leak persists, you should get professional help to examine the situation and determine the problem. Your machine may require additional maintenance due to malfunctioning equipment.


  1. Re-installation: If you discover that the problem is the result of poor or incorrect air conditioning installation, you should contact a specialist right away for a thorough inspection and, if necessary, a re-installation.
  2. Unclogging a clogged drainage pipe: If you come across a clogged drainage pipe, use a wet or dry pump to thoroughly remove the clog. This will clear the obstruction and allow the water to flow freely once more.
  3. Drain pan replacement: If the drain pan is cracked or damaged, have it replaced as soon as possible.
  4. Clean the air filter: The air filter in your air conditioner should be cleaned on a regular basis. You must remove the AC filter and clean it under running water after every brief time, such as a month.
