What to do in case of water dripping from AC?


When you observe water dripping from your air conditioner, it might cause concern and uncertainty. However, rest assured, as this is a prevalent issue encountered by many AC owners. Typically, it is relatively straightforward to address. In this guide, we will delve into the primary causes of AC leakage and offer straightforward solutions to restore its proper functioning.

What are the causes of water dripping from an AC?

Water dripping from an air conditioner is not always a sign of alarm, but understanding the causes is crucial. Here are some common reasons:

Condensation process

Air conditioning units operate by drawing in warm air from your room and cooling it. During this process, condensation naturally forms inside the unit. Under normal circumstances, the water is properly drained away. However, if there is a malfunction, it can result in leakage.

Clogged drain line

The most common cause of water dripping is a clogged drain line. Dust, dirt, and other debris can block the line, preventing water from flowing out.

Improper installation

If the AC is not installed level, it might cause water to pool and eventually drip.

Frozen evaporator coils

Sometimes, the evaporator coils freeze, and when they melt, excess water can cause dripping.

Low refrigerant levels

Low levels can lead to a drop in pressure, causing the evaporator coils to freeze and then drip water when they thaw.

How to fix water dripping from your AC?

Regular maintenance

Regular cleaning and servicing of your AC can prevent most issues related to water dripping.

Unclogging the drain line

Use a wet/dry vacuum or a stiff brush to clean the drain line. This can help remove any blockage and allow water to flow freely.

Checking installation

Ensure your AC unit is level. If not, adjust the supports to level it.

Thawing frozen coils

If you suspect the coils are frozen, turn off the unit and let them thaw. Also, check for and rectify any issues that could be causing the coils to freeze.

Refilling refrigerant

If low refrigerant levels are the problem, you will need a professional to refill it. Handling refrigerants requires expertise and is not a DIY task.

When to call a professional?

While certain repairs can be easily managed, others demand the expertise of a professional. If you find yourself uncertain about the problem or its resolution, it is advisable to seek assistance from a professional. Moreover, when dealing with electrical components or handling refrigerant, professional service is imperative.
