Why Your AC is Leaking Water? Reasons, Prevention & Best Repairs

20 April, 2026 | by admin

Today, an air conditioner has become a daily essential rather than a seasonal favourite. Its regular usage may result in some wear and tear, such as water leakage.

It not only adversely affects the efficiency, but also the functionality of the machinery. Availing air conditioning repair Dubai at the hands of professionals can prevent further damage to the machinery.

What Results in Water Formation in Your Air Conditioner?

The evaporator coil installed inside the AC unit helps in the cooling of the warm air as it blows over to create an indoor temperature.

As warm air starts blowing over the coil, condensation takes place. The water droplets so formed start dripping into a condensate pan, which finally leads to a PVC drain line outside.

Due to a lack of air conditioning maintenance in Dubai, the machine sometimes starts malfunctioning. Is water leaking inside the house from your AC machine?

Are you unable to make out the causes that lead to water leakage from your air conditioner? Here are some of the most common ones.

5 Common Causes Leading to Leakage of Water from the AC Unit

A leakage in an air conditioner can not only lead to internal damage, but also drive up the electricity bill. By availing air conditioning service in Dubai from expert and licensed professionals, it is possible to put a full stop to this ongoing problem.

A few causes that lead to leakage in the air conditioner, with tips on preventing the same, are:

1. Clogging of condensate drain – One of the most common causes that lead to water leakage in the AC unit is clogging of the condensate drain with dirt, algae, debris and dust. You may try to remove the debris with a wet or dry vacuum. If the problem still persists, it’s better to give a call to a professional service provider.
2. Damage to condensate drain pan – Is your air conditioning system too old? Then there are higher chances that the drain pan has become rusted or damaged. Keeping this problem unattended may even lead to a serious accident. As a solution, it will be good to replace the old drain pan with a new one within a time period of twelve to fifteen years.
3. Freezing of evaporator coils – Restricted flow of air and a dirty evaporator coil may lead to freezing of the coils. The ice so formed may melt quickly to fill the drain pan, thus leading to leakage. It will be good to monitor the level of refrigerant and clean the evaporator coils regularly to prevent early freezing of condensate.
4. Damaged condensate pump – A damaged condensate pump may also lead to water leakage from the air conditioning unit. A broken pump cannot pump water outside, thus leading to inconvenience. It will be good to get the part repaired or replaced at the earliest.
5. Improper installation of the AC unit – A poorly installed air conditioner or a random configuration of the condensate drain line may result in drainage issues. It may also lead to water leakage from the system. Hiring a reliable service provider like Ghumman Star Technical Services to install and maintain the system may prevent such unwanted situations.

These are some vital causes that may lead to leakage of water from the AC unit.

As A Conclusion!

The moment you suspect any type of malfunction, it is better to give a call to a professional service provider and get the problem fixed at the earliest.
