Possible Reasons for Water Leakage from Your Air Conditioner

Before we unfold all the mystery of how to fix air conditioner leaking water inside, it’s important to learn the possible reasons that cause the water leakage.

Here are all the reasons that lead to severe water leaking from split AC indoor unit:

Clogged drain line

When the drain line connecting the air conditioner’s drain pans becomes blocked, the drain pans cannot be emptied. A blocked condensate drain line is a problem because it prevents water from draining outside the house as it should. Because of this, water can seep into the home or room if it overflows the drain pan.

Damaged drain pan

If the drain pan of an older unit is corrupted or damaged, any water that drips won’t be able to make it to the condensate line. Damage to the drain pan might lead to a leak if it prevents water from draining properly.

Disconnected drain line

Your air conditioner can leak water because of an unplugged drainpipe. If the drain line is sloppy or poorly installed, this can occur. Your air conditioner’s drain pan is no longer watertight and might leak if this occurs.

Dirty air filter

If the air filter is unclean, less air will pass through to cool the evaporator coils. The coils eventually freeze because of the extreme cold. Leaks form, and water accumulates in the drip pan when the frozen coil thaws. Your air conditioner’s efficiency and performance might suffer from a filthy air filter, leading to higher energy costs.

Low refrigerant levels

Evaporator coils are susceptible to freezing with insufficient refrigerant. This can occur if the refrigerant is not correctly charged or there is a leak in the coolant pipes. Low refrigerant levels can negatively impact your air conditioner’s cooling ability and energy efficiency.

The thermostat is set too low

Evaporator coils can freeze up if the thermostat is too low. This can occur if the thermostat is set below 70 degrees Fahrenheit (21 degrees Celsius) or the air conditioner is left on continually during very cold weather. Condensation on the coils can get so heavy that it overflows the drip pan and finds its way into the building or room.

Condensate pump failure

Some air conditioners use a condensate pump to get the water out of the drain pan and into the condensate pipes. When the pump isn’t functioning properly, water collects in the drain pan, eventually leading to leaks.

High humidity

Extra condensation on the evaporator coils is another symptom of high humidity. This can occur if your home or room has inadequate airflow or if you live in a very humid region. More water will pool in the drip pan, increasing the risk of an overflow and subsequent leakage within the building or room.

Improper installation

Problems with water leaking can also be caused by incorrect air conditioner installation. This can occur if the air conditioner is not installed properly, for example, if the drainpipe is not slanted. Your air conditioner’s performance and efficiency can suffer, and your warranty can be voided if installed incorrectly.

Thus, these reasons can help you recognize water leakage from a split AC indoor unit. Remember, you can also use the same reasons to identify window air conditioner leaks inside the house.

Is Water Dripping from an AC Dangerous? Exploring Safety Considerations

Water pouring from an AC unit is not immediately threatening but can affect negative to your health and house over time. A coolant leak, on the other hand, might be hazardous to both you and the environment. In any scenario, a leak must be repaired by someone familiar with air conditioner repair.

Water pouring from an air conditioner can lead to mold and mildew development, which can cause allergies and respiratory issues. If it penetrates your walls, floors, ceilings, furniture, or electrical equipment, it can cause structural damage. If it accumulates on the floor or stairs, it can cause slips and falls.

How to Fix Air Conditioner Leaking Water Inside

If you find water leaking or collecting inside your home from your air conditioner, you can have an issue with your drainage system or evaporator coil. The leak should be repaired immediately to avoid future damage and health dangers.

Here, we will explore how to fix air conditioner leaking water inside your apartment or room for two air conditioners: window and split units. We will also provide some pointers on avoiding future water leaks.

Fixing Water Leakage from a Window Air Conditioner

A window air conditioner is a single-room cooling machine that rests on a windows. It contains an evaporator coil to chill the inside air and a condenser coil to release heat outdoors.

The condensation on the evaporator coil drops into a drain pan and exits via a drainpipe. Water might leak into the home if the drain pans or hose is blocked, broken, unplugged, or slanted wrongly.

So, if you don’t know how to fix the window air conditioner leaking water inside the house problem, here are some procedures to take to repair a window air conditioner leak:

1. Disconnect the equipment from the power source to guarantee safety throughout the repair procedure.
2. Locate and remove the air conditioner’s front panel to access the interior components.
3. A blocked air filter can induce ice development. If required, clean or replace the filter.
4. Examine the drain pan for debris or blockages. Clean it completely, making sure the drain hole is open.
5. Check that the window seal and the insulation surrounding the unit are in good condition and adequately sealed. Replace any worn seals.
6. Use a level tool to verify that the window air conditioner is balanced. If necessary, adjust the tool to encourage appropriate drainage.

So, this was how to fix air conditioner leaking water inside the window room. Let’s move to the next part and resolve the same issue for the indoor unit.

Resolving Water Leakage from a Split AC Indoor Unit

The interior component of a split air conditioner is linked to the external component through refrigerant lines. The indoor unit features an evaporator coil and a fan to circulate the cooled air throughout the space.

The compressor in the outdoor unit pumps the refrigerant, and the condenser coil in the outdoor unit releases the heat. Evaporator coil condensation drains into a pan and then to the outside through a pipe. Water can seep into a home if the drain pans or line is blocked, broken, disconnected, or frozen.

If water is leaking from AC indoor unit, follow these steps to repair it:

1. To prevent electrical shock, turn off the power to the indoor unit before beginning repairs.
2. Find the indoor unit’s front panel and unscrew it to access its inner workings.
3. To avoid ice build-up and guarantee unhindered circulation, remove the air filter, and clean it.
4. Locate the drain pan and remove any obstructions or standing water. Check for obstructions in the drainpipe and give it a thorough cleaning.
5. Clear the drain line of any debris using a soft brush or other specialist equipment.
6. Turn on the air conditioner to check for water damage after performing the procedures.
