Why is the air conditioner dripping inside?
To understand why your air conditioner is dripping inside, it is necessary to explain some of the basic functions of its system. The most common type for installation in homes is composed of two units. Such air conditioners are also called split systems.
The indoor unit has a heat exchanger, whose task is to transfer hot and cold air. Every time the air conditioner is turned on, this component is filled with gas under low pressure. This allows the air to be cooled.

As the gas cools inside the heat exchanger and turns into water due to condensation, the liquid collects in a drain in the indoor unit, which then passes through a pipe connecting it to the outdoor unit.
Under normal conditions, water drains properly without dripping, but some faults can cause a leak to appear in the room. There are several possible reasons why an air conditioner may drip.
If the filter is dirty, moisture can accumulate, causing water to drip from the appliance.

Another possible cause is a clogged drain. If the pipe is clogged, water will back up and start dripping from the air conditioner.
The condensate tray collects the liquid from condensation. If this part of the air conditioner is damaged, cracked, or not leveled properly, it can cause dripping from the indoor unit. Another possibility is a refrigerant leak, which leads to ice buildup in the unit.

When the frozen liquid melts, too much water leaks from the air conditioner. Among the more serious causes of dripping from the indoor unit is a problem with the evaporator. To ensure that the air conditioner is functioning properly, contact a professional technician.
This applies to any problem with the unit that requires immediate repair. Be sure to use the services of a professional who will engage in regular maintenance of the air conditioner. Causes of dripping from the indoor unit:
