Great professional services. We've had bad experiences with professional cleaners and aircon specialists before, so we were naturally wary about this at first. Fortunately, after our third try, we found the professional partner for our home (and even our home office). You can readily sense that they have been doing this for years because of their efficient system, from booking to dispatching. Their aircon specialists are also skilled and I heard from one of the specialists that they are required to renew their license annually. Great thanks and great job!read more

Let’s find out more about the common reasons why your aircon is dripping water here.

Quick Facts About Aircon Dripping Water

An air conditioner is more than a simple household appliance, it is something that many of us could not imagine living life without. That is especially true in the middle of the summer months, when the weather can get quite hot and suddenly, you find that you are spending as much time indoors as you possibly can.

Having an air conditioner that is often operational during the time can be of benefit but there are also some issues that may occur from time to time as well. One of those issues is when the Aircon is dripping water.

Since it is such a common problem to have dripping water from an air-conditioning unit, it is the purpose of this article to identify the reasons why it occurs and to offer some solutions that can get your unit back up and operational again.

First of all, you will be happy to know that an air conditioner dripping water is not typically a problem that is going to cause an immediate breakdown in the unit. It is an issue that needs to be addressed quickly, however, so that further problems do not occur.

One of the biggest issues associated with an air conditioner dripping water is damage that might take place to the home. Water is something that is associated with every air-conditioner but when it is operating properly, it will not drip into the unit and it certainly would not drip into the home.

Once the water begins dripping, however, it could quickly lead to damage to the nearby area and if it is left too long, mold may even develop. The following are some of the more common reasons why an Aircon is dripping water and what you can do to correct it.

Air Leak from Aircon Vent

One of the more common reasons why water may be dripping from the AC is because there is an air leak from somewhere around the area of the vent.

This is a relatively common problem and it is fairly easy to both diagnose and to fix. Quite simply, you need to inspect the unit carefully to see if there is air coming from anywhere other than the grates themselves.

If that is the case, you can purchase something to seal the leaks and the problem should be resolved.

Aircon Filter is Blocking

Another reason why you may be experiencing dripping water from the AC unit is because of the air filter. The air filter is not necessarily causing it to drip but if the filter is dirty, it is not getting the proper airflow and the AC unit may be freezing up to a certain extent.

When the AC unit shuts down, either because it is turned off or because the room has reached the proper temperature, the frost melts from the unit and the dripping begins.

This is also an easy problem to both diagnose and fix. Check the air filter on a periodic basis and make sure that it is clean. After cleaning or replacing the filter, the problem should stop.

Condensation Line is Clogged

There is a drain line that allows water that has accumulated to flow from the area without dripping into the home.

If you look into the condenser unit and the drip pan is full of water and overflowing, this is likely the problem. If you see any rust in the area, it is potentially a very serious problem. You need to unclog the drain to allow the water to flow away from the area.

A number of methods are available to unclog the drain, including blowing it out with compressed air. Since this is such a serious issue, however, it is a better idea for you to contact a professional and have them correct the issue for you.

Leak in Refrigerant

This is a more serious problem and it is one that requires the assistance of a professional. When a refrigerant leak exists, the vents are likely to leak water as a result.

The reason why this is the case is that the AC unit requires sufficient refrigerant levels so that humidity can be removed from the inside of the home. When water is removed from the home and it stays on the coil, it can freeze and eventually, lead to dripping. Contact a professional if this is an issue.

A Frozen Aircon Coil

There may be times when the evaporator coil can ice over and it causes the entire system to shut down. When the ice melts, it will ultimately lead to a problem with dripping water. This is a problem that should be assessed and corrected by an aircon professional.

These are the most common reasons why water may be dripping from an Aircon. If you are able to identify the issue, you can often correct it or understand the steps necessary to have it corrected for you.

My aircon is leaking water, is this normal❓

No. For most of the case, leaking water means that your aircon already needs to be cleaned. The accumulated dirt particles will cause the evaporator coils to freeze, thus the leaking water. But there might be other reasons too. Please contact us to help you check further.

Will dust cause problems in my AC❓

Accumulated through time, dust can definitely be one of the most common problems of air conditioners.

How Much Does it Cost to Have an Air Conditioner Leak Fixed?

In general, costs for servicing air conditioning units in Singapore can range from about $50 to $80 for one to two units.

The cost will depend on the number of units in your home and the extent of cleaning needed. Aircon cleaning services can be based on a one-time cleaning job or you can arrange for scheduled maintenance on a contract basis.

Is the water leaking from an air conditioner dangerous?

If the water leaking from the air conditioner evaporates and turns into a gas, the refrigerant may become dangerous. If you suspect that your air conditioner may be leaking refrigerant, you should call a professional air conditioning maintenance company immediately. If it is only water leaking from the indoor unit, it is safe. However, it is always best to call a professional AC specialist to check the entire system.

Should I turn my AC off if it is leaking water?

The first thing to do when there is any sign that your air conditioner has a problem that could cause major damage to your home is to shut off the power and find an alternative way to stay cool until the problem is sorted out.

How can I prevent my air conditioner from leaking?

Here are some things you can do to ensure your air conditioner does not leak:

- Have the unit checked from time to time by a professional
- Ensure your air conditioner is properly installed by a professional company
- Check the refrigerant level and top it up if necessary
- Check and clean the filters or replace them when necessary
- Clear the drainage line occasionally to prevent blockages from forming

When purchasing a new air conditioning unit, it is prudent to seek the expert opinion of a professional air conditioning technician. This will prevent you from buying a poor-quality unit or purchasing a counterfeit brand.

Do aircon compressors leak water?

Water leakage from an outdoor condenser or compressor happens when the condenser cools down the surrounding warm air, causing condensation to form. All air conditioners drip water, in fact, they should. Dripping water in the wrong place or a large volume may be a sign that something is wrong with the air conditioner.

Why does my AC leak after a service?

If the air conditioning unit was not properly installed, it might leak after a service. For example, there may be too much pressure in the pump, or the pipes may not have been tightened properly, causing the unit to leak water. Another reason may be that the condenser unit was not placed at the right level during installation.
