Read Why Is Your Mini Split Leaking Water. Find FAQ Answered

The use of technology implies the fact that, sooner or later, something in the system will fail. Our blog mentioned that proper care and maintenance of the equipment extend its service life for years, meaning thousands of hours of operation. However, no one is immune to technical issues that may arise unexpectedly. Today, we will discuss one of the common problems with HVAC systems: mini split leaking water. We intentionally divided this article visually and in terms of content into two parts. In the first part, we will provide an in-depth answer to why the problem may occur. In the second part, we will address the most Frequently Asked Questions related to the breakdown.

What Is What: Why Your Mini Split Leaking Water

By the way, it is important to emphasize that the problem is not necessarily related to the age or extensive use of the system. Nevertheless, all the reasons can be summarized into a concise list:

The simplest problem can lie right on the surface: clogging. If the drainage system is blocked with debris, dust, leaves, or other substances, it leads to uncontrolled condensate leakage.
Damage to the drainage hose also causes improper condensate drainage, and then you will notice that your air conditioner behaves strangely.
Component malfunctions. Some mini-split models are equipped with a condensate pump. Malfunctions with the pump also cause leaking water. We include improper evaporator operation here as well.
External environment. When the temperature outside drops, the mini-split's evaporator becomes too cold, leading to ice formation. When it thaws, water leakage occurs. Alternatively, high humidity levels might intensify condensation, resulting in water leaking from mini split.

Mini Split Leaking Water: FAQ

I noticed moisture on the wall, does that mean mini split leaking water?

Not necessarily. Various factors cause moisture on the wall, and it may or may not indicate that your mini-split is leaking water. The presence of moisture on the wall could be due to condensation, humidity levels, or other issues unrelated to the mini-split. To determine if your mini-split is leaking water, it is best you to call the service as quickly as possible.

What might have gone wrong so that my brand new mini split leaking water?

Sometimes a brand new mini-split system can experience a malfunction. In addition to the possible reasons mentioned above, adding incorrect installation or connection errors is essential. It's possible that mistakes were made during the installation process, such as improper pipe connections, inadequate fastening, or incorrect drainage hose attachment. To avoid warranty issues, stop using the mini-split and call a certified professional technician for assistance.

What could be the possible reasons for my mini split dripping water inside the room?

This symptom indicates that your mini-split or air conditioner is producing condensation, which starts to drip or flow inside the room instead of being properly drained outside.

This might lead to unpleasant consequences, such as damaging walls, ceilings, or furniture, as well as deteriorating indoor air quality.

Do leaks vary across brands? For instance, if there’s a Mitsubishi Mini Split leaking water, does it indicate something different not mentioned in your list?

Leaks in mini-split systems vary from brand to brand, including Mitsubishi mini-split. Each manufacturer may use different designs, components, and technical solutions, which impacts the reasons for leaks. For an accurate determination of the cause of the leak and its resolution, we recommend contacting us. We will be able to conduct a detailed diagnostic and provide the most suitable solution for your specific Mitsubishi mini split model.

Can I solve the leaking-water problem on my own?

While some minor issues might be simple to address, attempting to solve the problem on your own can be risky, especially if you are not familiar with the equipment or its workings.

What steps can I take to fix mini split leaking water?

We insist that calling the master will be the best solution. But if you understand all the risks associated with your intervention in the system and the responsibility, the following steps serve as a reference instruction.

Check the air filter: A clogged filter can obstruct proper airflow and increase condensation. Cleaning or replacing the air filter might help.
Inspect the drainage system: Ensure the drain pipe is clear and properly connected. Remove any debris or blockages that you can safely reach.
Check for ice buildup: If you notice ice on the evaporator coil, it could be causing water leakage. Turn off the unit and allow it to thaw before turning it on again.
Clean the evaporator coil: Dirt or dust on the evaporator coil can affect its performance. Gently clean the coil with a soft brush or compressed air.

Please note that any self-intervention in the mini-split system voids your warranty. Therefore, if your mini-split is still under warranty, please wait for a specialist to handle the issue.

How much does it cost to solve mini split leaking water?
