• Maintaining a Leak-Free Air Conditioner requires regular maintenance and attention to potential issues.

Why Does an Air conditioner Leak Water?

Indoor Water Leaks

If an air-conditioner leaks from the indoor unit immediately after it was installed, then the problem is installation related, otherwise, if it’s an older air-conditioner then the problem is indicative of a lack of maintenance.

Let us look at the reasons why air-conditioners leak, in both these instances.

Incorrect Installation

If an air-conditioner leaks from day one, the problem is likely installation related. Possible causes could be:

• The evaporator or indoor unit has not been mounted evenly – meaning one side is probably higher than the other.
• The coring of the hole on the wall through which the condensate drainpipe passes, is higher than the level of the drainpipe of the indoor unit. Gravity will cause the water to flow back into the indoor unit.
• If the drain hose is above the indoor unit, the hose is often bent, or the end of the hose is submerged in water and flows back.
• Rainwater flows through the pipe through the perforated hole.
• There could be a leak at the joint of the extension of the condensate drainpipe (If the leak is within your interior room).

Blocked Filters

This is the most common reason for an air-conditioner to leak from the indoor unit. When the air-conditioner is operating, the evaporator (indoor unit) draws in air, and together with the air it will pick up dust and debris from the ambient air. This dust settles on the filters, eventually forming a blanket over the filters causing the refrigerant gas to be trapped and frozen on the coils. Upon melting, the excess water will leak from the indoor unit.

Blockage of the Condensate Pipe

This is another common cause of a water leak. The condensate pipe is an ideal environment for the build-up of fungus and mold. If not attended to, the mold will eventually constrict the water flow. The water will back-up and find a way to leak from the indoor unit. Regular inspection and servicing will prevent the build-up of fungus and mold. Breathing fungus and bacteria from the mold is detrimental to health.

Leaking Condensate Pipes

Most condensate pipes are made of PVC and plastic, and over time these pipes get brittle and if they are not replaced, then they will leak.

Using an Air-conditioner at Low speed and Lowest temperature

Using an air-conditioner at its lowest speed and at its lowest temperature on a humid day, could result in the refrigerant gas not being evacuated quickly enough and thereby causing the indoor coils to ice up. This would result in drops of water falling from the indoor unit.

Outdoor Water Leaks

Exposed refrigerant piping

Armorflex is the soft insulation that wraps around refrigerant pipes. If this protective covering gets damaged or wears out, warm air can touch the cold copper pipes inside. This causes condensation – just like when water droplets form on a cold glass on a hot day. It’s the same principle we learned about in science class.

Water dripping from the outdoor unit’s brass valves

You might notice water leaking from the metal valves connected to the refrigerant pipes on your outdoor unit. This is usually just condensation. It happens because cold gas flows through these valves, and when it’s hot and humid outside, moisture in the air turns into water droplets on the cold surface. This can also occur if any part of the pipe isn’t insulated where it connects to the valve, allowing warm air to touch the cold pipe.

Water leak from below the outdoor unit (condenser)

Most outdoor units have a small hole in the center of their bottom. This hole is there to let water drain out when the air conditioner is working in heating mode. You see, when an air conditioner heats a room, it’s basically working in reverse, and water collects in the outdoor unit instead of the indoor one.
If you plan to use your air conditioner for heating often, you might notice a plastic plug near this hole. That’s there so you can attach a drain pipe if needed, to guide the water away from the unit.

DIY Fixes for Aircon Leaks

First things first, you need to figure out where the leak is coming from. Your air conditioner is made up of several components, and any one of them could be the culprit. You’ll need to inspect the unit thoroughly to pinpoint the exact location of the leak. Look for any signs of moisture or water buildup and pay close attention to the different parts of the system, like the coils, the drain pan, and the condensate line.

Once you’ve identified the source of the leak, you’ll have a better idea of what’s causing the problem and how to fix it. It’s like being a detective – you’ve got to gather all the clues before you can solve the case!

Preparing the Work Area

Now that you know where the leak is coming from, it’s time to get ready to tackle the repair. Gather all the tools and materials you’ll need, like a spanner, a screwdriver, and some cloths or towels to clean up any water. Make sure you have a safe and accessible workspace to work on the air conditioner, too. You don’t want to be cramped up in a tight space or trying to work on the unit while it’s still running.

Once you’ve got everything ready, it’s time to get to work. Just remember to take your time and be careful – you don’t want to make the problem worse by accidentally damaging any of the components.

Accessing the Air Conditioner’s Components

Alright, now it’s time to get inside the air conditioner and take a closer look at the parts that might be causing the leak. Carefully remove any panels or covers that you need to access the internal components. This might take a bit of effort, but it’s important to do it safely and without damaging anything.

Once you’ve got the unit open, you’ll be able to see the different parts that make up the air conditioner, like the coils, the compressor, and the drain pan. Take a close look at each of these components to see if you can spot the source of the leak. It might be something as simple as a clogged drain line or a problem with the drain pump.

Cleaning the Condensate Drain Line

One of the most common causes of air conditioner leaks is a blocked or clogged condensate drain line. This is the line that’s responsible for carrying the water that’s produced by the air conditioner’s cooling process out of the unit and away from your home.

If this drain line gets blocked, the water can’t flow out properly and it’ll start to back up, causing a leak. To fix this, you’ll need to clean out the drain line. Start by locating the drain line and then use a wire or a small brush to gently remove any debris or buildup that might be clogging it up. Make sure to flush the line with water to ensure it’s completely clear.

Once you’ve got the drain line cleaned out, you should be able to get the water flowing freely again and stop the leak.

Unclogging the Drain Pan

Another common problem that can lead to air conditioner leaks is a clogged drain pan. The drain pan is the shallow tray that’s located underneath the air conditioner’s coils, and it’s designed to catch any water that drips down from the coils.

If the drain pan gets clogged with dirt, dust, or other debris, the water won’t be able to drain out properly, and it’ll start to overflow, causing a leak. To fix this, you’ll need to carefully remove the drain pan and give it a good cleaning.

Use a mild detergent and a soft brush to scrub away any buildup or gunk that’s accumulated in the pan. Make sure to rinse it thoroughly and check that the drain hole is clear and unobstructed. Once you’ve got the drain pan all cleaned up, you can put it back in place and see if that’s solved the leak.

Replacing the Drain Pump (if necessary)

If the leak is still persisting after you’ve cleaned the drain line and the drain pan, there’s a chance that the problem could be with the drain pump. The drain pump is responsible for actively pumping the water out of the air conditioner and into the drain line.

If the drain pump is faulty or not working properly, it can cause the water to back up and leak out of the unit. To fix this, you’ll need to replace the drain pump.

Replacing the drain pump can be a bit more complicated than some of the other repairs, so you might want to consider calling in a professional if you’re not comfortable doing it yourself. They’ll be able to safely and properly replace the pump and get your air conditioner back up and running without any leaks.

Maintaining a Leak-Free Air Conditioner

Now that you’ve got your air conditioner all fixed up and working properly, it’s important to keep it that way. Regular maintenance is key to preventing future leaks and keeping your unit running smoothly.

Make sure to clean the air conditioner’s filters on a regular basis and keep the area around the unit clear of any debris or obstructions. It’s also a good idea to have a professional HVAC technician come in and service the unit once a year or so, just to make sure everything is in tip-top shape.

By staying on top of the maintenance and being proactive about addressing any issues that come up, you can help ensure that your air conditioner stays leak-free and keeps your home cool and comfortable for years to come.

So there you have it, folks – everything you need to know about solving the drip dilemma and fixing a leaky air conditioner. Just remember to take your time, be careful, and don’t be afraid to ask for help if you need it. With a little bit of elbow grease and some know-how, you’ll have that air conditioner back in working order in no time!
