Do LG portable air conditioners need to be drained? ›

You may need to drain the unit anywhere from once a day to once a week or more. Check the water collection tray or removable bucket regularly, and empty it when it's full or nearing capacity. Many models also have a full-tank indicator light or alarm to alert you when it's time to drain.

A: The LG 10,000 BTU Portable Air Conditioner, Model # LP1018WNR does not need water to work. It doesn't use water at all. Is uses R410A Refrigerant to cool much like your car's air conditioning or a refrigerator.

If it fills the bucket when operating in cool only mode, then the air filter is likely dirty, making the cooling coil operate so cool that it condenses water. Clean the filter in that case.

When condensation builds up inside the portable AC's tank without being drained, water can overflow and leak out of the unit. As with any moist environment, the tank filled with stagnant water can also become a breeding ground for mold.

In general, portable air conditioners should be drained after every 8 hours. The frequency varies depending upon the model you own. Few air conditioners work efficiently without draining for a month.

To determine how many BTU you need to cool a 20 x 20 room, multiply the room's length by the width, then calculate 20 BTU for every square foot. Four hundred square feet x 20 = 8,000 BTU.

As a general rule we advise you to buy an Air Conditioner with a minimum 7000BTUs as this is the minimum required to call a small room (18sq/m) on a hot day. Medium rooms (24sq/m) need around 10,000BTUs and larger rooms and office spaces (36sq/m) require around 15000BTUs.

How many BTUs do you need for a 12x12 room? There are too many variables to answer that question with any degree of certainty, in general for room that size 6000 to 8000 BTUs should be sufficient.

Where does the water go with a portable air conditioner? ›

Part of the cooling process is removing humidity from the room. When first installed or after the unit has not been used in awhile, it is normal for the tank to fill up quickly and require more frequent emptying. Even once an hour can be normal.

Most portable air conditioners are designed to be self-evaporate, which means they typically do not require manual draining. They are equipped with a condensate system that cools down the condensate and recycles it to enhance the cooling efficiency.

Portable air conditioners use a standard window venting kit to expel exhaust, similar to a clothes dryer venting system. Most portable units have water reservoirs that help dehumidify the room. These reservoirs need to be emptied periodically, although some come with optional hookups for a drainage hose.

If water is not draining properly from the unit unto the outside: Check for a clogged drain pipe, and clean the drain pipe if necessary. Check for dirt and debris in the base pan, and clean it if necessary.
