How air conditioners work?

Normally it includes in air conditioners functioning that it produces water or condensation. It happens when air conditioners absorb the humidity and heat from inside air of the house. In the indoor air conditioner, evaporator coil is present which reduces the humidity.

The condensation starts dripping and accumulate in the drain pan. This dripping water comes out of the air conditioners ductpties and flow through the PVC pipe which is also called condensate line of drain Thus, water that comes from the interior unit is carried by this drain pipe, which exits outside next towards the condenser.

Why is my air conditioner leaking water?

If the AC condensation cannot work properly means not evaporate or nor it properly carried away, then in this situation water leakage might be occur from your unit.

In this situation, your first step is to check that why your air conditioners are not evaporate or drain properly. If you are able to diagnose this problem, then you are also able to solve this problem.

Well, you don’t have to worry about anything in this situation because tempindoors provide all the information through which you will be able to solve your air conditioning problems easily.

Common reasons of water leakage in air conditioners:

If you want to know why is my air conditioner leaking water? in air conditioners then you have to check all other components which normally deals with the condensation like drain pipe, evaporator coils, drain pan or condensate pump.

Common Reasons

Clogged condensate drain line:

This happens because dirt, debris and algae is accumulated in the drain line and blocked the drain line through which it causes water leakage from ac unit. Basically the drain pans water overflows and then water moves towards the unit. It might be possible that this issue is the main reason that why is my air conditioner leaking water?

Here’s one question arises in your mind that what’s the solution for this problem. Thus, this is how to solve the issue.

How to unclog a condensate drain line?

  • Turn off your air conditioners at thermostat and your circuit-breaker panel.
  • Find the drain line which is near to the condenser. Basically it’s a PVC pipe with plastic pipe.
  • Remove that cap and find where clog is, using flashlight.
  • Remove that clog carefully so it not goes deep in the pipe. If you are not able to reach the clog or your drain line not cleaned overall. Go to step 7
  • Slowly pour only 1 cup of white vinegar in the pipe.
  • Then replace such cap and then wait for 30 minutes before turning on your air conditioners.
  • If you are not able to reach the clog or your drain pipe is not cleaned overall, then use vacuum to such all the trapped water and that clog. Use vacuum for just 3 to 4 minutes and then replace such cap and go further.

Dirty Evaporator Coils:

Basically air conditioners cool the house by reducing humidity and also heat from air by using refrigerant which basically moves with the help of evaporator coils. On coils, moisture condenses just because of the cold refrigerant.

If your evaporator coils are so much dirty so in result hot air cannot properly pass through the coils and your coils becomes too cold. On coils, the condensation solidifies into ice rather than evaporating.

So in result, when air condition turns off, that ice starts melting and a specific amount of water starts dripping from unit. This reason also important to understand that why is my air conditioner leaking water?

How to clean your evaporator coils?

There is one major way to clean the whole evaporator coils with no rinse cleaner of evaporator coil.

  • First of all, turn of your air conditioner at thermostat and your circuit-breaker panel.
  • Remove access panel and then locate ac evaporator coils.
  • Remove dust from evaporator coils with the help of dog Brush or compressed air.
  • Before applying the no rinse cleaner read the no rinse cleaner instructions on the can carefully. Reapply this cleaner to that areas which remains dirty.
  • Now replace such panel and turn on the power supply.

Disconnected Drain Line:

Well, water leaking issue happens just because of disconnected drain line or due to improper installation of drain line. So, the answer of this question that why is my air conditioner leaking water? is improper drain line installation. Air conditioners condensation drips into the drain pan and then moves to PVC pipe which is called condensate line and drain line. This drain line carries water from the inside unit and empties towards outside. Locate such drain line which is near the inside unit. So, check such connection that its properly secure or not.

How to fix disconnected drain line?

  • First of all, turn of your air conditioner at thermostat and your circuit-breaker panel.
  • Use pliers or screwdrivers to reconnect this drain line and straighten any kind of kinks in drain line.
  • Now, turn your power supply on and check if there’s any water leakage or not.

Damaged and Rusted drain pain:

Normally moisture condenses on evaporator coils starts dripping and then collected in the drain pan. Well air conditioners have two types of drain pans, one drain pan is in the bottom of evaporator coils or air handlers. Secondary or I say back up drain pan is in the bottom of the whole unit. Damaged and Rusted drain pain comes under the reason of why is my air conditioner leaking water?

So, such drain pan empties in drain line which normally carries water from unit to outside of the house.

But if your units drain pan is cracked and rusted then it will be the cause of water leakage or accumulated at the bottom of the unit.

You can easily check the leakage of the drain pan. Frist of all, turn off your AC at thermostat and through breaker panel. Now, remove such access panel and starts locating drip pan. Slowly put some amount of water in the pan and then observe the flow of water with the help of flashlight. You will see if there’s any cracked then water will starts dripping from such point. Or if your pan is not rusted or damaged then all the water flow to the drain line.

How to fix damaged drain pan?

Well, in this situation the best option is to replace your old rusted or cracked drain pan with the new one. However, minor rusted cracks easily repaired with the help of waterproof sealant.

  • Turn off your AC at thermostat and through the circuit-breaker panel.
  • Remove access panel and find the leakage in the drain pan. Primary one drain pan is placed in the bottom of air handlers or evaporator coils. Secondary one is in the bottom of your unit.
  • The primary one drain pan is normally weld on. In case your pan is cracked then you have to dry all it contents by using rug or dry vacuum while it’s attached with the unit. On the other side, you can remove the secondary pan easily and clean or empties all its contents.
  • To improve the sealant’s adhesion, sand the region surrounding the fracture using fine-grit sandpaper.
  • Apply that sealant and leave it for 2 hours. Now, test that what you repair is properly works fine or not by pouring some amount of water in the drain pan. As an alternative, run your AC for few hours before visually inspecting the drips from pan.

Broken or damaged condensate pump:

Few air conditioners use condensate pump rather than gravity to push water from pan to drain line. So, broken or damaged condensate pump is unable to push water towards the drain line. But I will tell you that overflowing pan is not always indicating that your condensate pump is broken or damaged. Other issue like clog, which causes the water in the pan to spill over. if condensate pump is broken then this issue comes under the reasons of why is my air conditioner leaking water?

How to fix damaged or broken condensate pump:

  • Turn off your AC at thermostat and through the circuit-breaker panel.
  • Remove access panel and find the leakage in the drain pan. Primary one drain pan is placed in the bottom of air handlers or evaporator coils. Secondary one is in the bottom of your unit. The primary one drain pan is normally weld on. In case your pan is cracked then you have to dry all its contents by using rug or dry vacuum while it’s attached with the unit. Make sure that anything like dust or debris is stuck between the connection and the parts of pump. Also check the loose wires.
  • If your condensate pump is broken, then replace your pump.

Are dirty filters being responsible for water leakage in air conditioners?

To know that why is my air conditioner leaking water? first you have to check that your systems air filters are dirty or not. Well, in this case I said “Yes”, dirty filters are responsible for water leakage in air conditioners even its not directly work with the condensation which is produced by unit. Basically dirty filters cause leakage by the impeding flow air around evaporator coils.

As I said before that air conditioners remove humidity and hot air means heat from inside air of the house by using the refrigerant which is flowing through evaporator coils. This refrigerant allows the moisture to condenses on evaporator coils. If your AC filters are dirty then in this case warm air is unable to circulate

dirty air filters

properly which causes the evaporator coils too cold like an ice. Now, ice forms not on the coils but also on filters. When you shut down your air conditioner that ice starts melting and you will see water dripping starts from the unit.

If your AC filters are not cleaned and changed for many years then you have to replace such filters with the new one. Regular changing of air filters is necessary for the good performance. Well, you need to change your AC filters after 30 to 90 days depending on the quality of your unit filters. if your are not changing your air filters then you know very well that why is my air conditioner leaking water?

Is water leakage in air conditioner is dangerous?

Well, it’s not completely harmful because many times water leakage happens just because of blockage or accumulation of the dirt in the unit. It causes serious damages to your house and became an expensive repair if you left the issue unresolved.

If fluid is leaking from your AC unit then you have to pay attention to this issue because refrigerant leakage is not common as compared to water leakage. Refrigerant leakage is much more hazardous. Refrigerant is lethal because if evaporates it becomes like a gas. In the end, if refrigerant is leaking from air conditioner, repair your system as soon as possible. As your question why is my air conditioner leaking water? always water is not leaking from air conditioner but sometimes refrigerant is leaking from air conditioner.

Here are few indications through which you can easily understand that refrigerant is leaking from your unit:

  • Major increase in the electricity bills.
  • Your house takes too much time to get cooled.
  • Your Air Conditioner starts blowing warn or I say hot air.
  • ice has formed on the unit.

Conclusion:

All types of air conditioners produce water in the condensation form. If you are facing water leakage issue inside your house from you air conditioner than more likely there are many issues with your unit components which are usually used to produce condensation. Now, you know the reasons which are included in the question why is my air conditioner leaking water?

House owners easily find the problem by just inspecting the component like drain pan, condensate drain line, evaporator coils and air filters. In various cases, many house owners solve this issue by themselves but if it still continues leaking water then HVAC professional will help you in solving this problem.

Now, I hope you get the answer of your question “why is my air conditioner leaking water” clearly.
