Is water leaking out of your window Air-conditioning and into your home? H2o leaking from a window AC is a serious problem. Major damage can occur if you don't deed fast

The first affair you should exercise is turn off your window AC. Next, get a towel and soak up the water so information technology doesn't damage your home.

Okay, so at present that that's done, it'south time to start figuring out what your next steps are.

In this commodity, I'll go over what you need to practise if your window air conditioner is leaking h2o. I'll also provide step-by-footstep instructions for troubleshooting a leaky air conditioner in any state of affairs.

Check if the condensate drain is clogged

In about cases, if a window AC is leaking h2o inside, then it's due to a clogged condensate bleed. So the first affair that you should cheque is if the condensate drain is plugged.

What'south the condensate bleed used for?

All ACs produce water when they cool the air. The reason is that common cold air holds less moisture than warm air. So when the AC cools warm moist air, some of that moisture comes out of the air and turns to liquid.

Every bit the Ac runs, the liquid condensate collects in a drain pan. The condensate drain is a hole in the drain pan that allows excess water to drip out of the dorsum of the window AC. If the hole gets clogged, and so at that place is a possibility that the drain pan volition overflow and start leaking water in your firm.

Why does the condensate drain get clogged?

The condensate drain tin go clogged from all sorts of things:

Dirt
Mold
Slime build-up
Leaves
Dead animals or insects
Rust

Keep in mind that a chock-full condensate drain won't e'er cause your window Air conditioning to leak water. Most newer window AC models are the dripless type. This means that they won't normally baste out water from the back of the unit.

How to fix a chock-full condensate drain on a window AC

To fix a chock-full window Air-conditioning condensate bleed, follow these steps:

Unplug the window AC from the power outlet. If y'all're going to exist unclogging your window AC'south drain, remove its power source.
Find the condensate drain. The condensate drain is located somewhere on the dorsum of the window AC. Go outside and look for the drain pigsty. Take annotation of how big the hole is, yous'll need to discover a tool that is the right size to make clean it out.
Unclog the condensate drain. Use a thin tool such as a needle or paperclip to poke inside of the condensate drain and dislodge the debris. You may exist able to apply a thin screwdriver if the bleed hole is big plenty. In most cases, this is enough to unclog the bleed and get all the backlog water out of the drain pan.

After you unclog the condensate drain, go ahead and plug the Air-conditioning dorsum in and turn it on to test its operation.

If the condensate drain gets chock-full over again, you lot may need to open up the window Air-conditioning and clean its drip pan out.

Check if evaporator curl is frozen

The evaporator roll is the part of the window AC that gets cold. In some cases, the evaporator coil will get excessively common cold and a block of water ice will form over the coil.

Once an evaporator coil freezes, in that location is a good chance that the window Air conditioning will first leaking water.

Why does a frozen evaporator coil crusade a window AC to leak h2o?

A frozen evaporator coil is essentially a big cake of ice on your window AC. As the water ice melts, water starts dripping off the evaporator scroll. Usually, the baste pan is able to grab all the water drops. However, if the coil is excessively frozen, water may start dripping out of the front of the window Air-conditioning unit of measurement.

What causes a frozen evaporator coil?

If your window AC's evaporator ringlet is freezing, then that is a bad thing—for many reasons.

Your window AC won't produce enough airflow since the ice is in the mode.
You window AC might start leaking water when the water ice melts.
A frozen evaporator ringlet is indicative of another result, such every bit depression airflow or low refrigerant.

How to ready a frozen evaporator coil

If your window AC'southward evaporator curlicue freezes, then you have a bigger issue on your hand. Most likely it's an airflow issue.

The first thing you should check is the air filter. Make sure that the air filter is clean. If the air filter is dingy, then clean it.

A clean air filter keeps air flowing through your window Air-conditioning. A dirty air filter will inhibit airflow and potentially cause a frozen coil.

One time you get sufficient airflow flowing through your window Air-conditioning unit, the evaporator scroll shouldn't freeze anymore. If it's still freezing, so it's likely that the Air-conditioning is depression on refrigerant.

Nether normal operation, air conditioners don't "use upwardly" refrigerants. So if your AC is low on refrigerant, that means that there is a refrigerant leak somewhere.

Unfortunately, if your window Air-conditioning has a refrigerant leak, yous're ofttimes better off replacing the unabridged unit rather than trying to get it stock-still. Information technology's oft cheaper to just buy a new 1 instead.

Cheque if the air filter is dirty

The air filter is the office of the AC that captures particles. There are 2 reasons why an air filter is important:

The air filter captures particles so the air conditioner's internal components don't get dingy.
The air filter captures particles to keep them out of the air in your room.

Why does a dirty air filter crusade a window AC to leak water?

If the air filter gets dirty, there volition exist a reduction in airflow through your window AC. A dirty air filter volition potentially cause the evaporator curlicue to freeze over. Every bit the evaporator coil thaws out, water may leak from the forepart of the Air conditioning into your home.

What causes a dirty window AC air filter?

A muddied air filter in your window Ac is zilch to be afraid of. In fact, it'south completely normal to accept some grit accumulated on your AC's air filter.

As your window AC runs, it sucks in air from your room, through the air filter, and into the Ac. As air flows through the air filter, small particles such every bit dust, hair, and pollen become trapped in the air filter.

Fortunately, the air filters in most window ACs are reusable, and so they tin can exist cleaned and used again.

How to make clean a window AC air filter

Cleaning the air filter in a window Air-conditioning is a simple job that you should practice once a month. To clean the air filter in your window Air conditioning, you need to remove the front panel to admission the air filter. Next, remove the air filter from the filter slot.

Later on you get the filter out of the AC, clean the filter by rinsing information technology out with water. You can use a soft-tipped nylon brush and soap to scrub the filter if more cleaning is needed.

I have another article that has step-by-step instructions on how to make clean a window Air conditioning air filter.

Check if the refrigerant is low

The refrigerant is the fluid inside of the Air-conditioning that moves heat from the inside of your room to the exterior of your house.

Low refrigerant levels may cause a window Air-conditioning to start leaking water.

Why does low refrigerant cause a window Air-conditioning to leak h2o?

If the refrigerant is low inside your window AC, then the evaporator whorl may freeze up into an ice cake. Once this happens, your window Air-conditioning may start leaking h2o as the ice block thaws out.

What causes depression refrigerant in a window AC?

In normal circumstances, refrigerant won't leak out or get "used up" in an air conditioner. The refrigerant is inside the window AC in a "closed-loop" organization and so information technology should never come into contact with the outside earth.

Nevertheless, refrigerant may sometimes leak out of a malfunctioning AC. For instance, if 1 of the refrigerant pipes in your AC cracks, the refrigerant volition leak out. Also, refrigerant may leak out of a corroding evaporator scroll.

What to do if your window AC is low on refrigerant

If your window AC is low on refrigerant, you have two options:

Hire a licensed HVAC professional person to set the leak and refill your window AC with refrigerant.
Replace the entire window AC unit.

Of these ii options, information technology'due south often cheaper to replace the unabridged window Air conditioning unit. Specially if it's a pocket-sized one.

Hiring an HVAC professional person to fix your window Air-conditioning may seem like the smarter route, but the costs of labor are frequently too high when compared to just buying a brand new AC.

The only time I would recommend hiring an HVAC professional to set up a window AC is if it is a large, expensive window AC unit.

Check if the condensate pump is working

The condensate pump is a device that moves liquid condensate from your window AC up and out of your home. A condensate pump is required if your window Air conditioning is located at a lower elevation than the place that you want to drain it at.

For instance, condensate pumps are typically constitute in basements. Since the basement is beneath basis level, a condensate pump is needed to pump the condensate up and outside the house.

Why does a broken condensate pump cause a window AC to leak water?

If your window AC uses a condensate pump, and then the AC will collect excessive amounts of h2o if the pump is not working.

As the AC runs, condensate collects in the AC's drain pan. If the drain pan fills up with water, h2o will start to leak out of the window Air conditioning.

What causes a broken condensate pump in a window AC?

An air conditioner's condensate pump may break due to one of a few things:

Mineral deposit accumulation on pump's parts
Grime build-up inside the pump'south internal components
Worn out mechanical or electric components in pump

In any case, information technology's often easier to replace the condensate pump than to endeavour and get a broken one working over again.

If yous want to try to troubleshoot a broken condensate pump, so you should outset by inspecting the float switch and cleaning the pump out.

Window AC leaking water inside when it rains

If your window Air conditioning is leaking water inside your home when it rains, then you need to check two things:

Bank check if the window Air-conditioning is sloped down toward the outside so it drains exterior when it collects water.
Check if the seal around the window unit is intact and so water can't infiltrate the Ac unit of measurement.

Window AC needs proper slope when installed

If it rains outside, pelting water may collect inside the Ac's baste pan. If your window AC is not sloped downwardly toward the outside, so that rain water may cease up leaking within your house.

To make certain that doesn't happen, ensure that your window Air conditioning is installed with the proper slope. Also, brand certain that the window Air-conditioning'southward bleed pan is articulate and the bleed hole is open.

Window Air conditioning needs a seal around the unit

If your window Air-conditioning is leaking around the perimeter of the unit of measurement inside your domicile, and then the seal around the AC unit of measurement may not be working.

Inspect the seal and barrier around the window Air conditioning to ensure that there are no gaps that would allow rainwater to go inside your home.

If you find a gap, you tin can apply a slice of cream tape or aluminum tape to block the gap—depending on how large the gap is.

Window Air conditioning leaking h2o outside

Water leaking out of the part of the window AC that is outside is normal in most cases. So there is no need to exist alarmed.

Even "dripless" window AC units will sometimes "leak" water out of the dorsum during humid days. This is normal beliefs and indicates that your window Ac is doing it's job at cooling and dehumidifying your dwelling house's air.
