Do LG portable air conditioners need to be drained?

Some LG portable air conditioners should not be neglected when it comes to draining them, as certain humidity conditions and AC modes can result in water accumulation.

Portable air conditioners are quite sensitive units that need a little bit of extra attention when it comes to maintaining the internal components of it.

They work by extracting a lot of the humidity from the room in order to cool the environment efficiently. Part of taking care of the internal components of your portable air conditioner involves draining it when necessary.

If you are an LG portable air conditioner owner, it may help you to know if your unit needs to be drained like other portable air conditioners. This helps you keep track of your unit and its operation.

LG portable units and draining

For LG portable air conditioner owners wondering if their unit needs to be drained, the answer is yes, your unit needs to be drained under certain conditions.

It is rare to come across a portable air conditioner that needs no form of draining or has no drain plug, but depending on the specific model you have, the method of draining the unit differs and you need to consult the user manual to find out how to correctly drain your particular unit and how often draining is required.

Do LG portable air conditioners need to be drained?

LG portable air conditioners do need to be drained. If you have an LG unit with the latest technology such as the self-evaporation mode, this does not mean that your unit does not need to be drained.

Depending on how much humidity is in the air, the unit might still accumulate water that needs to be drained when self-evaporation mode cannot drain it. However, certain modes may not collect any water at all.

When you use the portable unit in “Cool” or “Fan” mode (in low humidity), there is no need to drain the unit. LG portable units are designed to function with some moisture in the collection tank as this increases their efficiency.

Using the air conditioner in dehumidification (Dry) mode may require that you install the drain hose by connecting it to the drain outlet at the back of your unit (or at the bottom).

The hose needs to be placed in a suitable position and location, such as an outside floor drain, for the water collected in “Dry” mode to be drained.

The Dry mode of the air conditioner extracts moisture from the room and works best in humid conditions. Water can rapidly gather in the unit resulting in the unit needing to be drained when in Dry mode.

How frequently do you need to drain your LG unit?

With all portable air conditioners, including an LG, the rate at which you need to drain your portable air conditioner varies and is dependent solely on the climate in your location.

If it is excessively hot on a given day, the humidity levels in the air will be high. The more humidity there is in the environment, the more moisture the unit has to extract from the air.

This will result in the unit filling up quicker than it normally would and, in turn, needing to be drained more frequently.

Draining your LG without a continuous drainage hose

You can either drain your LG portable unit with a hose that you run to outside, or you can place a shallow pan or container under the drain outlet of the unit, remove the drain cap from the outlet and let the water drain into the pan or container.

You need to be extra careful when you do it this way as the unit needs to be tilted backwards slightly to ensure most of the water drains into the pan or container without dripping.

The hazards of overflowing water from the unit

Excess water in your LG air conditioner can result in issues in its functionality and in your home. If your portable unit tank fills up to the point that it overflows inside the unit, this can damage some of the internal components of the air conditioner.

If your home has particular flooring that does not deal well with water and your unit overflows onto the floors, this can spell disaster for your flooring or your carpets.
