Water Dripping From AC Indoor Unit

When you come back home after a day’s hard work, you want to kick back and relax. Interrupting your relaxation is the constant drip-drip of water. Water dripping from split AC indoor unit is not only annoying but also an eyesore in your otherwise beautiful home. Good news is that you are not the only one suffering from this problem and there are lots of things that you can do to contain it. So, first and foremost, remember to get seasonal maintenance of your HVAC unit done by professionals. Once the servicing is completed, keep checking your unit for any apparent troubles.

How To Fix Water Dripping From Split AC Indoor Unit

If water is dripping from the split AC indoor unit, do not be alarmed. It can easily be fixed either by you or with the aid of HVAC professionals. However, before doing anything, disconnect the unit and dry any wet areas caused due to dripping water. Also, ask yourself whether you are comfortable opening the indoor unit and tackling the problem on your own. If you have any doubts, its best to let the professionals take care of the problem. If you are sure, here are a few things which you can do to rectify the problem:

  • Blockage In Condensation Drain Line – Accumulation of dirt, sludge, debris, mold, algae, and fungi can cause clogging of the drain line. As a result, the water formed due to condensation is unable to drain, causing overflow which spills inside your house.

How To Fix – You need a vacuum with a hose attachment to fix this problem, a bucket and a screwdriver. Open the front section or panel and remove the filters. Then remove the front panel and locate the pipe which drains the water. Disconnect these pipes and collect the excess water inside them in a bucket. Once it is completely drained, suction out the blockage using the vacuum cleaner. After this, pour a small quantity of vinegar or chlorine bleach down the drain pipes to kill any bacteria and fungi.

  • Disconnected Drain Line – Drain line drains the water collected in the drip pan. If this line is disconnected it fails to empty the pan and it overflows causing water leakage inside.

How To Fix – Fixing this problem is simple. All you need to do is connect the drain pipe to the drain pan. However, if the pipe keeps disconnecting easily, you may have to replace it altogether to avoid future occurrence of the issue.

  • Cracks or Holes In Drain Pan – Due to corrosion or rusting the drain pan can develop cracks or holes. These holes may cause water to leak through the indoor unit.

How To Fix – To fix cracks or holes in a drain pan you need a vacuum cleaner to suction out the standing water, flashlight and epoxy glue. To begin with clear out all the water inside the drain pan using a wet vacuum cleaner. Once it is empty, shine your flashlight through the entire length and breadth of the drain pan to detect leaks. Using epoxy glue close all the leaks. If the cracks are too many, best would be to replace the entire drain pan with a new one.

  • Dirty Air Filters – Seemingly a small thing, but dirty air filters can cause the freezing of evaporator coils due to an inadequate passage of air.

How To Fix – This one is relatively easy. All you need to do is either clean the dirty air filters with a brush and water. Else, at the peak of the season, you can change it every four to six weeks.

  • Frozen Evaporator Coils Due To Low Refrigerant Level – Low refrigerant level also causes the freezing of evaporator coils, which in turn cause water to drip from split AC indoor unit.

How To Fix – This is one problem best handled by HVAC professionals. It because they need to find the source of a refrigerant leak, seal it, and top the level to adequate. It is something which is critical to the working of an AC, so leaves no room for any error. Since you are not well versed in such technicalities refrain from experimenting. Give us a call today.

  • Faulty Installation Of The Unit – To err is human. For all that matters, the installation of your AC may not be correct. While installing, somebody may have made a mistake which causes water dripping from the split AC indoor unit.

How To Fix – If after checking you found no obvious source for water dripping, you should call in the HVAC experts. Only they can help you understand if it is an installation issue and fix it. Again, it is something you cannot do on your own.

  • Faulty Condensation Pump – If the condensation pump is faulty, it too can cause dripping of water inside from the AC indoor unit. This is something you cannot check on your own.

How To Fix – Book an appointment with the HVAC expert to handle this problem correctly. Do not tinker with your AC unit on the assumption you can correct the problem all on your own. For all you may know, you might just make a bigger muddle of things with your limited knowledge in this field.

Moreover, they have just the right equipment at their disposal to do the job efficiently and effectively. Therefore, if the problem is big and out of your scope, it is best to let the experts handle them.

Conclusion

Water dripping from slit AC indoor unit is not always a cause for concern. If the water does not dry up in a day, on its own, only then you need to worry. Even then, you can do half the things yourself to remedy the occurrence. However, if you feel, you are not equipped to take care of things, call the experts.

Frequently Asked Questions

Your split AC could be dripping water because its condensate line is blocked by dust, dirt, or sludge. If that is the case, use your regular wet/dry vacuum cleaner to suck out the lodged impurities from the condensate pipe, which should solve the dripping problem.

There are two reasons why your split AC is dripping water inside, namely:

1. The drip tray is cracked or has holes in it.

2. The drain line has become clogged, causing the water to back up and overflow from the drip tray.

An AC should normally not drip water. Fortunately, the reasons behind the drip are pretty standard, so there’s nothing to worry about.

There are 3 main reasons your split AC is leaking water inside. The first two have to do with the condensate line. Either the drip tray is cracked, or the drain line is clogged. In the first case, you can patch up the cracks in the drip tray or replace it with a new one. In the second case, you can unclog the drain line using your vacuum cleaner. The third reason for the water leak could be the thawing of the iced evaporator coils. In this case, you should call a technician to confirm that the problem is not low refrigerant levels. If it is, only they can solve the issue.

Your new air conditioner leaks water because its drip tray is full to the brim. It happens when the drainpipe has a blockage due to which the condensate cannot flow out. If your AC is old, the other possibility is that the drip tray has corroded and developed holes from which the water is escaping.
