Although air conditioners are designed to drain water outside, they can also leak water inside the home. The amount of water an air conditioner leaks depends on many factors. These include the amount of air being produced, the humidity outside, and what temperature it is set to. The condensate line, which carries the water outside, can be damaged or clogged, allowing it to overflow and leak into the home.

Dirty air filters
A dirty air filter can lead to several problems with your air conditioning system. These problems can include the inability to cool your home adequately or a hot temperature inside. A simple solution to these problems is to replace the air filters once a month.
Dirty air filters can also cause your evaporator coils to freeze. This can damage your air conditioning system and cost you money in increased energy bills.
Drain pan damaged
The drain pan is most likely to cause your air conditioner to leak water. The drain pan can crack over time and allow water to leak onto other parts. This can cause further damage. You should have your drain pan checked by a professional every year to prevent further damage. This way, he can spot any cracks before they become a bigger problem.
Water can back up in your home if your drain lines are blocked. You can use a dry/wet vac to clear the drain line or hire a professional. Another way to fix a clogged drain line is to replace the drain pan. The drain pan is usually located under the evaporator tubes in your air handler. This pan collects condensation that drips from your evaporator coil. Water can leak into the drain line if the drain pan becomes damaged.
Clogged condensate drain line
A condensate drain pipe is a PVC pipe attached to the exterior wall of your home near the outdoor unit. Most condensate drain pipes have a T-shaped vent tube and a cap to cover the top. You can easily clean clogged lines by vacuuming the debris.
The drain line may be clogged if you notice standing water around an AC unit. The condensate pan is designed to drain water outside the unit, but a clogged drain line can cause water to back up and overflow into the unit. This can cause water damage to the home and mold growth.
Damaged evaporator coil
When water begins leaking from an evaporator coil in an air conditioning system, the cause is likely biofilms or mold. It can also be caused by refrigerant leaks or a clogged air filter. This problem can be easily detected early so you can either fix it yourself or shut down your system. It’s best to avoid running the system with a leaking coil, as it could damage the compressor and worsen the situation.
Water leaking from an air conditioning system is a big headache. The evaporator coil consists of a large tube with fins. It will likely stop working if it is damaged and start leaking water. While a puddle of water on the floor is not necessarily a problem, it’s a sign that the evaporator coil is leaking water.
