85% of air conditioner owners experience water leakage issues at least once in their lifetime. Although water leakage can be a minor issue, it can impact the air conditioner’s service life if you overlook it for a long time. Therefore, understanding the causes of air conditioner water leaking is essential. This short content concerns the common causes of air conditioner leakage and some quick solutions. Let’s get started.
Common Reasons For Air Conditioner Water Leakage
Water leakage from an air conditioner can happen for several reasons. In this section, we’ll explore the most common causes.
Clogged Drain Line
Drain line clogging is a common reason for air conditioner water leakage. Dust and dirt may accumulate in the drain pipe, blocking the normal flow of condensation. This blockage forces the water to leak into the unit.
Solution:
- Use a vacuum to clear the blockage.
- Regularly clean the drain line with a vinegar solution.
Damaged or Rusted Drain Pan
A drain pan is an air conditioner accessory that collects condensation from the cooling process. With age, this pan can rust and crack, leaking water.
Solution:
- Replace the damaged drain pan; it was damaged due to rust.
- Ensure regular maintenance of the aircon to present rusting issues.
Low Refrigerant Levels
If the refrigerant level goes down, the evaporator coil may freeze. This freezing can lead to water dripping when the ice melts. The level of refrigerant goes down if there’s a leakage. This is often considered a serious situation for the air conditioner unit.
Solution:
- Call a professional to check refrigerant levels.
- Identify and fix refrigerant leaks immediately.
Dirty Air Filters
Dirty air filters may also cause water leakage. When filters are clogged, they restrict airflow, which causes the evaporator coil to freeze. After the ice melts, water buildup and leakage occur.
Solution:
- Replace or clean air filters periodically.
- Ensure filters are checked during routine maintenance.
Improper Installation
Improper air conditioner installation can cause water leakage. For example, if the air conditioner is not installed on level ground, water can pool in the unit rather than flow down. If the unit is not installed properly, water can leak in many other ways.
Solution:
- Ensure the air conditioner is installed correctly and leveled.
- Hire professionals for installation or relocation.
Split-type aircon leaking water
Split-type aircon may leak water for several reasons. For example, clogged drain lines, dust, and debris blocking the pipe can be the reason for water leakage for split-type ACs. If the air filters are diagonal, the refrigerant level is low, and the coils can freeze, resulting in water leakage. Improper installation can also be the reason for split-type AC having water leakage. You may also check the damaged or rusted drain pan.
Window-type aircon leaks water
Similar to split-type ACs, dirty or clogged air filters can restrict airflow in window-type ACs. This can lead to ice formation and subsequent water leakage as it melts. However, unlike split-type ACs, improper installation in window units—where the unit isn’t slightly tilted backward—can directly cause water pooling inside the unit. A damaged or rusted drain pan can also contribute to leakage in both types.
Mitsubishi aircon water leakage problem
Mitsubishi is the most popular aircon model in Singapore. Water leakage in the Mitsubishi Aircon is a common problem. Several common factors we have already discussed can lead to this problem. They are:
- A blocked or clogged drain pipe
- Dirty air filters
- Low refrigerant levels
- Improper installation
- A damaged drain pan or a
- Malfunctioning condensate pump
Daikin aircon is leaking water inside.
Daikin is another popular aircon model in Singapore. Water leakage in this AC brand is not uncommon. The reasons are also almost the same as those we have already discussed. They are:
- Cogged or blocked drain pipe
- Dirty air filters
- Low refrigerant levels
- Installation error
- And more
LG & Samsung aircon leaking water
Water leakage in LG and Samsung brand ACs is a common problem we handle regularly. This can be caused by a variety of common reasons that we have already covered.
- Blocked drain line
- The obstructed drainage system,
- Dirty filters can restrict airflow,
- Inadequate refrigerant levels
- Improper installation
- And more
Fixing the aircon leaking water problem
Below are a few techniques to follow if you want to fix the water-leaking problem of your AC:
- Check the drain line for clogs or blockages and clean it.
- Clean the air filters to ensure proper airflow.
- Inspect the drain pan for cracks or damage and replace it if needed.
- Check refrigerant levels and recharge if low.
- Ensure proper installation with a slight tilt backward for drainage.
- Unclog the condensation drain.
- Fix refrigerant leaks by contacting a professional.
- Call a technician if the problem persists.
FAQ
Is it normal for an air conditioner to leak water?
Some condensation is normal. But if your unit is leaking excessive water, it’s an indication of a problem.
Can a leaking air conditioner damage my home?
Leaking air conditioners can damage walls, floors, and ceilings and cause costly repairs. Therefore, if you detect unusual water leakage, hire a servicing expert immediately.
How often should I check my air conditioner for leaks?
Inspect your air conditioner unit every few months. If not possible, inspecting it before peak summer is highly recommended.
Should I repair a leaking air conditioner myself?
You can solve minor issues without professional assistance. For example, you can clean a clogged drain by yourself. But if it’s a more complex issue, such as refrigerant leaking, then you need to call air conditioning servicing professionals.
Is it normal for the aircon to leak water?
A small amount of water leakage is normal for an AC. However, large water leaks indicate issues that need to be solved by professionals.
Why does my aircon leak water from the front?
Water leakage from the front can be caused by improper installation. If the problem persists, consult a professional.
Why is my portable aircon leaking water?
A clogged water tank, blocked drain hose, or improper venting can cause water leakage in the portable air conditioner. Dirty filters or low refrigerant can also cause water leakage.
Conclusion
As you already know, air conditioners can leak water for many reasons. A small amount of water leakage is normal for ACs. Keep your unit clean to reduce the leakage problem. For the best results, master clean your AC several times a year. Don’t hesitate to call a professional for assistance when needed.
