What causes the air conditioner to leak?
We often attribute the cause of an air conditioner leak to one of these 4 reasons :
When your air conditioner is running continuously, condensation leak is a common problem that you might have to deal with. This leak is caused by the excess condensation that is formed from the evaporator coil.
Normally, condensation from the evaporator coil falls into the drainage system or into the drain pan. When it’s working properly, you won’t see any water leaks around your air conditioner. The formation and preservation of overload condensation is mainly responsible for leaks. However, in most cases, the problem can be resolved by itself once the AC is switched off and has time to entirely exhaust the condensation.
Blockage of the Drain Pipe
The most common reason behind sudden leakage is a blockage in the drainage line which will stop water from flowing freely out of the air conditioner.
Dust, debris, algae and dirt, which accumulate overtime, cause water to overflow out of the drain pipe. Leaking water from the AC continues if the condensation process goes on. So it is highly recommended that you clean your air conditioner filter at least once every 3-4 months (or more frequently when dust levels are high). If not maintained, the dust will block the line and force the water to overflow onto the drainage area.
On the back of the indoor air conditioner, insulation is generally installed at the place where the unit connects to the wall. The insulation system helps to soak up the condensation that grows on pipes close to the back wall where the unit is placed.
As soon as the insulation wears, it loses its capability of absorbing the condensation that is produced by an ac and it causes a leak near the back of it.
If it is cool outside and you run your air conditioner, it will cause water to flood because it won’t be able to evaporate as quickly as it should. This may be very common at night time when the outer surface remains comparatively cool. To avoid this problem, you should simply use the fan to pass air and turn off the air conditioner when it is cool outside.
If the issue aggravates, make sure to call in a service technician who will look for underlying issues .
