Split air conditioners (AC) are popular among homeowners and businesses because of their efficient cooling and quiet operation. They consist of two units: an indoor unit that blows cool air into the room and an outdoor unit that houses the compressor and condenser. However, like any other appliance, split AC can develop problems over time, and one of the most common issues is water leakage.

Split AC leaking water is a problem that can cause significant damage to your property if addressed. It is caused by the accumulation of condensation that forms on the indoor unit’s evaporator coil. The evaporator coil absorbs heat from the room and turns it into cool air. As a result, water droplets form on the coil due to condensation, which then drips into a drain pan that leads to a drainage pipe. If the drain pipe is clogged or the drain pan is damaged, water will leak out of the indoor unit and cause damage to your walls, floors, and furniture.

In this article, we will discuss the reasons for water leakage from split AC and what you can do to prevent it. We will also provide tips on how to fix the problem yourself and when to call in a professional AC service in Gurgaon. So, if you are experiencing water leakage from your split AC, keep reading to find out why and how to fix it.

There can be various reasons for this issue, and addressing it as soon as possible is essential to avoid any further damage to your unit. Here are some common reasons for water leakage in split ACs and their symptoms:

  1. Clogged air filter – A dirty or clogged air filter can cause the evaporator coil to freeze and eventually overflow with water. You might notice reduced cooling and airflow from your AC unit.
  2. Faulty condensate pump – A condensate pump pumps out the excess water collected in the AC unit. If it is faulty, water can accumulate and leak from the unit. You may notice a gurgling sound coming from the AC unit.
  3. Dirty evaporator coil – An evaporator coil can accumulate dirt and debris over time, causing it to freeze and eventually overflow with water. You may notice reduced cooling from your AC unit.
  4. Low refrigerant charge – A low refrigerant charge can cause the evaporator coil to freeze, leading to water leakage. You may notice reduced cooling from your AC unit.
  5. Improper installation – If the AC unit is installed correctly, it can prevent improper drainage and water leakage. You may notice ac dripping water  from the unit or a musty smell.
  6. Broken or clogged drain pipe – A broken or clogged drain pipe can cause water to accumulate and leak from the unit. You may notice water dripping from the AC unit.
  7. Frozen evaporator coil – A frozen evaporator coil can cause water to leak from the unit. You may notice reduced cooling from your AC unit.

If you ignore water leakage from your split AC unit, it can lead to several consequences. Firstly, it can damage your unit and cause it to malfunction.
