It will collect any condensate from the indoor unit, however, when it rusts or cracks, there will be some leakage complication going on
Your AC behaves in a certain manner because of certain concerns! For instance, it leaks water because of three concerns, however the first is because it has a missing or cracked drain pipe; it may have a blocked drain line or a blocked drain filter, but more often than not, the air conditioner unit malfunctions & behaves like it is leaking when one of these things is off! A blocked drain line becomes blocked with debris such as mold, dust, & dirt, and in most cases, when the condensate drain line is blocked, water tends to escape & drain outside. The line often appears backed up, causing the water to seep through. This can be fixed only when the pipe is flushed & cleaned, then note that algae & fungi can be responsible for this clogging on your AC’s drain line, but you need to continuously pour some vinegar inside the drain to kill mold & algae. In case the infestation is rampant, consider calling professional Heating & A/C cleaners to handle it. A wet & dry vacuum cleaner can also work when attempting to unclog your Heating & A/C system. The drain pan should be located underneath the evaporator coil. It will collect any condensate from the indoor unit, however, when it rusts or cracks, there will be some leakage complication going on. This means that water will not be able to drain out quickly. A similar challenge occurs when the drain pan is misplaced or non-existent hence the continuous leakage. Finally, the challenge of blocked air filters also leads to leakage, and usually, when the airways are blocked, airflow is restricted, leading to many concerns with the Heating & A/C system, and one of these is the fact that it can cause frozen evaporator coils that drip excess water, and change these filters & have the Heating & A/C worker examine the system always.
