Water dripping from an AC unit, indicating that your air conditioner is leaking, is a frequent concern for homeowners. This issue, often a sign that your air conditioner is leaking water, should not be ignored due to its potential implications. Therefore, it is crucial to understand the causes to address it effectively.
In this article, we will explore the causes of water leaking from AC indoor units, discuss whether it poses any danger, and provide insights on whether it is safe to use an AC when water is dripping.
The Cause of Water Leaking From AC Indoor Unit
Water leaking from an AC indoor unit is a common issue that can occur due to various reasons. Understanding the causes can help identify the problem and take appropriate measures. Here are some of the primary reasons behind AC water leakage:
● Dirty Air Filters
AC air filters play a crucial role in maintaining adequate airflow and removing dust and debris from indoor air. When the air filter is dirty and clogged, it restricts airflow, leading to the evaporator coil freezing. As this coil thaws, water collects in the drain pan and may start dripping from the unit.
● Improper Installation
An incorrectly installed AC unit can result in water leakage. Issues such as improper tilt or insulation can cause condensation to leak inside your home. Ensuring the AC unit is installed correctly is essential to prevent potential problems.
● Leaking Refrigerant
The refrigerant in an AC system is responsible for cooling the air. If there is a refrigerant leak, the pressure in the system may drop, resulting in the evaporator coil becoming too cold and freezing. When the coil thaws, it can lead to water leakage.
● Frozen Evaporator Coil
When the airflow over the evaporator coil is restricted, or there is an imbalance in refrigerant levels, the coil may freeze. This occurs with continuous AC usage without maintenance or underlying system issues. Once the coil thaws, water can drip from the unit.
● Condensate Drainage Issues
During the cooling process, the air conditioning system extracts moisture from the warm indoor air, which then condenses into water. This water typically collects in the drain pan and should drain away from the unit through a condensate drain line. However, if the conditioner is leaking water, it could be due to a clogged or improperly installed drain line.
● Piled Up Mold and Fungus
Mold and fungus can build up in the AC unit and block drainage, while blockage may result in water overflow and unit leakage. Regular cleaning and maintenance can help prevent the growth of mold and fungus.

● Old Pipes
AC unit drainage pipes can deteriorate, causing cracks or leaks. If the pipes are damaged, water can escape and cause leakage. Regular inspection and maintenance can help identify and replace any worn-out pipes.
● Overload or Oversized Unit
Lastly, suppose the AC unit is too large for the cooling space. In that case, it can cool the air too quickly, leading to the evaporator coil not having enough time to drain appropriately. This can result in excessive water leakage.
Is Water Dripping from AC Dangerous?
Water dripping from an AC unit may cause concerns about potential hazards and risks. While it is not inherently dangerous, there are several impacts to consider:
● Property Damage
Excessive water leakage can cause damage to walls, ceilings, carpets, and other nearby structures.
● Electrical Hazards
Water leakage near electrical components poses a risk of electrical shorts, which can lead to fires or damage to the AC unit.
● Slips and Falls
Water dripping from the AC unit can create slippery surfaces, increasing the likelihood of accidents such as slips and falls.
Is It Safe to Use AC When Water Is Leaking?
Using an AC when water leaks from the unit can pose certain risks and potential hazards. Therefore, here’s what you can do in such a situation:
- Switch off the AC unit to prevent further water leakage and potential damage.
- Address the issue to a professional technician.
- Clean up and dry the area to prevent further damage and discourage mold growth.
- Take precautions. For example, place towels or containers to catch the water and protect nearby surfaces.
So, is water dripping from an AC dangerous? It certainly can be. An air conditioner leaking water poses various risks, including property damage, electrical hazards, and mold growth.
Therefore, it’s crucial to address any signs of your air conditioner leaking water promptly to ensure the safety and efficiency of your air conditioning system. It is best to follow the recommendations above to ensure your safety.
