It is shocking to find your air conditioner dripping water at the time when you really need it on a hot day in Malaysia. Leaking of water is one of the widespread aircon issues among homeowners and businesses in Kuala Lumpur and other parts of Malaysia. It is useful to understand why it occurs and how to deal with it so that you can avoid having to deal with expensive repairs and rather awkward moments.

And given the fact that you have somehow developed a leaking aircon, the following is a detailed guide that will assist in finding the causes, when to attempt to do it yourself, and when to start looking up professional aid.

Part 1: How Your Aircon Makes Water

Before going into the reasons why air conditioners may be leaking water, it should be made clear that leaking water is a natural process involved in the functioning of air conditioners. Your AC will evaporate the moisture out of the air during cooling down in the hot, humid climate like in Malaysia. This water would flow out through a drainage system well marked out – failure of which results to undesirable leakage.

At times when humidity is high in Malaysia, one split unit can make 5-20 liters of water per day. Such a production of water is very natural but the problem comes up when the drainage system breaks off or is clogged.

Top 8 Causes Why Your Aircon Is Leaking Water

1. Blocked Drainage Pipe (Most Likely Cause)

The Problem: Malaysia is a hot and humid environment that favors algae, molds and bacteria growth in the drainage pipes. These together with dust and debris work to create blockages that do not allow the efficient drainage of water.

Symptoms: Dripping water in the indoor unit, musty smell and poor cooling.

DIY Fix:

• Find the outlet pipe to drainage (often on outside of your house)
• Blockages can be sucked out using a wet/dry vacuum
• Flushing in clean water adding some drops of bleach
• To test the flow, pour the water in drain pan

When to Call a Professional: The inability to reach the drainage system without risking own safety, or blockage remains after the cleaning.

2. Filthy Air Filter

The Problem: Urban dusty environment in Malaysia filters can get clogged easily. The more the dust the faster the filters clog. The clogged filters lead to a reduced amount of airflow leading to evaporator coils freezing and overflowing after they become defrosted.

Symptoms: Decline in airflow, freezing of coils, accumulation of water near it.

DIY Fix:

• Switch AC off and take the filter out
• Wash in soaps and water
• Dry, then reinstall
• Renew when broken or very soiled

Prevention: Clean cleaners once a month when in heavy use, change every 3-6 months.

3. Low Levels of Refrigerant

The Problem: Lack of refrigerant leads to coiling up of evaporator. Once ice is melted, an excessive amount of water is created compared to the capacity of drainage system.

Symptoms: Frost on evaporator coils, system cooling, hissing, increased electric bills.

Special Service Note: The handling of refrigerants needs licensed technicians. This cannot be a do-it-yourself lowering and needs a refrigeration system expert.

4. Faulty Installation or Improper Slope

The Problem: In case your AC is not leveled correctly or the drainage pipe does not have the right slope, the water flow out is prevented by resisting the drainage channel and enters the unit instead.

Symptoms: Water leaking all the time no matter how it is cleaned, water standing in drain pan.

Technical Analysis Required: The right installation should be done by a professional i.e., the professional might be needed to reframe the unit and put the drainage pipes in place.

5. Damaged/Disconnected Drain Pan

The Problem: Condensation falls into the drain pan, and not to the drainage pipe. The water may leak inside your room, due to cracks, rust and improper alignment.

Symptoms: Dripping of water at the area slightly below indoor unit and visibly damaged drain pan.

DIY Diagnosis: The drain pan is visually accessible, though it will most likely need a professional to replace.

6. Evaporator Coil Frozen

The Problem: Coils may freeze due to various issues such dirty filters, low refrigerant, or vents, that may be blocked. As it melts, it overflows the drainage system with more water than it can be drained.

Symptoms: Presence of ice on coils, low airflow, over spill of water as the ice thaws.

Immediacy: Turn off the AC in order to thaw it, followed by underlying causes (cleaning the filter, vents check).

7. Giant AC Unit

The Problem: Over-sized AC Unit: A unit that is too big cools within a short time but does not have time to sufficiently dehumidify resulting in a build-up of humidity and possible drainage.

Indicators: Shorter cooling cycles, elevated humidity levels even when cooled, uneven comfort level.

Professional Assessment: Type of work that needs load calculations with the help of trained professionals in order to establish the right size of AC.

8. Ageing of Components and Components Breakage

The Problem: Older units can be outdated having aged seals, corrosion of drain pans and failing pumps, unable to cope with regular production of water.

Indicators: Having more than one problem at a time, repeated repairs required or seen signs of corrosion or wear and tear.

Quality: Detailed work that involves measuring of the repair vs. replace.

Troubleshooting Guide Step By Step

What to Do the Moment You Realize That Your Tap Is Leaking

1. Turn off the AC: Avoid additional water damage and inspection
2. For the Water Contains: Cover floors and furniture with towels or containers
3. Look for the Obvious: Visible obstructions, clogged filters or ice build up
4. Write the Problem: Take pictures to insure or provider claims notes

Do It Yourself Inspection Checklist

Safety First: Never expose your electricity to conduct electrical checks on the components without switching off.

✓ Filter Condition: Replace and look through to see any dirt, damage, and/or blockages
✓ Drain Pan: Look for cracks, rust or torn portion
✓ Drainage Outlet: Look outside outlet drainage point to see any blockages
✓ Ice Formation: Look at evaporator coils to see whether they are frozen
✓ Unit Level: Provide indoor unit suitably placed
✓ Evident Breakdown: Search freeze, loose parts or damage

In Situations in Which DIY Solutions Fail

When basic troubleshooting does not help eradicate water leakage, or find out that your problem is more complicated than simple cleaning, you should seek professional help. Some issues are not simple and demand specialist tools and specialists with possible resources (parts) that only competent technicians should deal with.
