Damaged or Dirty Air Filters

Dirty or damaged air filters can cause your split AC unit to drip water by blocking the flow of air through the system. This can cause the evaporator coil to malfunction, resulting in water droplets forming and dripping from the unit. Additionally, clogged, dirty air filters can put extra strain on the fan motor. This causes the filter to work harder than necessary, leading to more condensation, a broken AC fan, and water leaking.

To resolve this issue, start by inspecting your damaged or dirty air filters. Depending on the situation, you might need to clean or replace them. It’s recommended that you check and clean your dirty air filter every month, particularly during the colder seasons.

If your AC’s air filters look fine, it’s possible that the problem is with other parts of the system, such as the evaporator coil, drain line, or refrigerant level. Or the restricted airflow could be the result of something else. Either way, these issues may require a professional technician to fix.

Air Conditioner Not Properly Leveled

If your indoor AC unit is not leveled properly, water will eventually accumulate inside it and start leaking. The condensate drain pan responsible for collecting and draining the water produced by the air conditioner will also overflow as a result. As if that’s not enough, it can leave you with a clogged condensate drain line, too, preventing water from draining properly and causing it an overflow.

Luckily, fixing this problem is relatively easy. Simply make sure your air conditioning system is level when installed. For starters, you can use a level tool to check for any unevenness. If the unit is not level, just adjust its legs or install shims underneath to further level and stabilize the unit.

Additionally, you should check if you’re dealing with a clogged condensate drain line. If you are, clear any blockage and ensure that the drain pipe is properly connected. If the problem persists, it may be necessary to call a professional technician to check and fix the system.

Clogged or Disconnected Drain Lines

A clogged or disconnected drain line can cause water leaks in your split AC system by preventing condensate water within the unit from unloading properly. These fluids will eventually overflow and leak out of the system.

A clogged drain line can also cause water to back up in the condensate pan of a split air conditioner system, leading to your AC leaking water. Meanwhile, disconnected drain lines can cause the condensate water in the system to overflow and drip out.

Fixing clogged or disconnected drain lines will help prevent water from leaking out of your air conditioner. Start by inspecting the condensate drain line as thoroughly as you can. Clear any blockage and debris that may have accumulated in the line. If the line is disconnected, ensure that it is properly re-attached.

Regular cleaning of the drain line is also important, as is checking for any bends or kinks in the line (these might cause blockages). If the issue still persists, better call a professional HVAC technician.

Low Refrigerant Levels

Low refrigerant levels in an air conditioner can cause water leaks by causing the evaporator coil to freeze. This can lead to excess condensation and water droplets forming and dripping from the unit. Furthermore, it can also cause your unit to work harder than it should, leading to even more condensation and leaving your AC not cooling properly.

To resolve these issues, have your indoor AC unit checked by a professional. They’ll use specialized equipment to determine the refrigerant level and recharge the system if necessary. Regular maintenance is necessary to ensure the refrigerant levels stay at optimal levels, prevent the evaporator coil from freezing, and avoid any future water or refrigerant leak.

And since low refrigerant levels can be caused by leaks in the system, the technician will also look for any leaks and repair them. It’s vital to address this particular issue as soon as it’s detected to prevent further damage to the unit.

Thermostat Set Too Low

Setting the thermostat too low can lead to your AC leaking water since it will cause the unit to run longer and produce more condensation. This will eventually result in water droplets forming and dripping from the system. Moreover, if the unit is not properly sized for the room, it may not be able to handle the amount of condensation produced when the thermostat is set too low, again leaving the air conditioner leaking water.

To fix this, simply adjust your AC’s thermostat to the appropriate temperature. This will eventually resolve your unit’s condensation problem as well as eliminate leaking water from your system.

If the thermostat is broken, it should be replaced or repaired by a professional technician. Additionally, you should check the unit’s wiring to make sure that it is connected properly and that there is no damage.

Improperly-Sized AC Units

An mentioned earlier, installing an AC that’s improperly sized for the room can result in the unit producing more condensation than the unit can handle. An oversized air conditioner will cool the room too quickly, causing the evaporator coils to produce more condensation than the drain pan can handle or the drain pipes can remove. This will cause the water to overflow and leak from the unit. To top it off, the oversized AC will cycle on and off frequently, causing more condensation to be produced, increasing the risk of water leaks.

To resolve this problem, you should consult with a professional technician to determine the correct size of the unit for the room. The technician will consider factors such as the room’s size, insulation, and usage to determine the appropriate size of the unit. If the unit is too large, you may need to downsize and replaced the AC with another that’s more properly sized for the room.

AC is Installed in a Humid Area

Installing an air conditioner in a humid area can result in water dripping out of the unit due to the excess moisture in the air. The AC unit’s cooling process causes the moisture to condense on the coils, which then drips out of the unit through a drain.

To prevent water dripping from split AC indoor unit in a humid location, make sure the unit is properly sized for the space and that the coils and drain are clean. Keep the area around the unit clear of debris and make sure the unit is level. Also, ensure that the drain line is not clogged and the condensate pump is functioning properly. Regular maintenance, such as cleaning or replacing a dirty air filter can help prevent leaking water inside the system.

Drainage System Not Properly Installed or Maintained.

An improperly installed or maintained drainage system can result in your air conditioner leaking water. The combination of a clogged drain line, a broken condensate pump, and a cracked drain pan can cause water to back up and leak out of the unit. A poorly installed unit can also lead to improper drainage and leaks.

To prevent this, ensure that the unit is installed correctly. Have a qualified HVAC technician install the unit and conduct regular maintenance checks. Ensure that the unit is level and that the drain line is not clogged. The condensate pump should also be checked to ensure it’s functioning properly.

Regularly cleaning or replacing the dirty air filter can greatly help prevent clogs and malfunctions in the drainage system. So keep an eye for any signs of leakage or water pooling and have it checked by a professional if you notice any.

Malfunctioning Compressor or Fan Motor

A malfunctioning compressor or fan motor can leave your Ac leaking water. When the compressor or fan motor is not working properly, it can affect the cooling process and cause the coils to freeze over, resulting in excess moisture and water leakage.

Additionally, a malfunctioning compressor or fan motor can cause the unit to shut down unexpectedly. This can also cause water to leak out of the unit, not to mention lead to other minor issues.

A qualified HVAC technician should be called to diagnose and repair the compressor or fan motor. Regular maintenance and cleaning of the unit can also help prevent the compressor or fan motor from malfunctioning and causing water leaks.

Damaged Insulation on the Refrigerant Lines

If the insulation on a unit’s refrigerant lines are damaged, it can leave your AC leaking water. That’s because they help keep the refrigerant at the proper temperature.

When they become damaged, it can cause the refrigerant to become too cold and freeze over. This will ultimately cause water to leak out of the AC. Additionally, damaged insulation can cause the refrigerant to leak, which can also cause water to leak out of the unit.

Again, a qualified HVAC technician should be called to diagnose and repair the damage to the insulation. The technician should also check for refrigerant leaks, and if any are found, repair or replace the lines as needed.
