What People Are Saying

Rated 3 out of 5 by from Cools well until design flaws catch up. Purchased model LP1213GXR last year and it worked fine last summer and most of Purchased model LP1213GXR last year and it worked fine last summer and most of this summer. Towards the end of a very humid summer it started blowing out water from under the top squirrel fan while water collection tray in the bottom never filled up. I assumed that there was a blockage somewhere that prevented the water from dripping down. Once I pulled the cover I discovered the problem. Under the top squirrel fan was a plastic tray with 2 small holes tight against the lower coil. The holes are so tight to the oil that the opening is effectively cut in half. Probably worked great in the nice clean development lab but in the real world of dust, pollen , black lab hair etc. the little holes eventually got plugged up so the water collected under the squirrel fan. I took everything apart to clean out the holes and saw 2 other little holes on the other side of a partition in the plastic tray under the squirrel fan. I loosened up the plastic tray and carefully drilled the 4 holes to 5/16", drilled an opening in the little partition, and added another hole to the side in case the larger holes clog up. The final adjustment was to replace some open celled foam used to seal around the return air opening. The foam trapped water and whatever appeared to be getting moldy do I replaced it with a closed cell vinyl weather stripping. So far so good. No water spraying and the bottom tray in collecting water. A final note. I suddenly realized that this unit uses inside air in for cooling. So hot air is being pulled into the room to replace the air blown outside. I'll rig up a double hose rig for next year.

Rated 2 out of 5 by from 3rd Summer and it's Done For I purchased the 12k BTU LG Portable unit in 2013. It worked pretty well the first year. Last year wasn't as good and this year it's pretty much worthless. It now makes strange noises, shuts off after a few minutes, and blows warm air. The de-humidifying feature won't even work anymore. Spent close to $500 on it so I expect better quality over time. This is my 1st portable unit and have experienced greater longevity (more than 6 years) from window/casement units.

Rated 1 out of 5 by from This product is a piece of junk!!!!!! I purchased this unit a year ago and it worked fine about 6 months total out of 12. It started blowing out water so I drained it and it worked ok for about two weeks then it started doing it again. I called service and they told me to do it again so I did. It worked for a weeke then started blowing water out again but this time it didn't stop. The FL or full indicator function didn't work so I had no way of knowing it was full of water. But the last time I drained very little water out and started it again it started blowing out water again. I trashed and went and bought a different brand. Do not purchase any LG a/c they are nothing but junk. I would not recommend any of their a/c units!!!!!!

Rated 1 out of 5 by from blowing hot air I bought this last summer and it worked fine. This year when I turned it on it blows hot air. Very unhappy with air conditioner.

Rated 1 out of 5 by from Doesn't Last. We purchased this in April, 2013. The first summer, it worked pretty well. The room is not that big and it was running during the day for about 4 months. The summer of 2014, it started not cooling consistently. The filters were changed every 4 days or so. We just set it up again, preparing for this year's heat. It's blowing hot air and it occasionally sounds like the compressor is not functioning properly. Look for a different brand unless you want to replace it in a couple years. Very disappointed in this product.

Rated 4 out of 5 by from Pretty good, but could be better This is my first portable AC unit so I don't have a lot of experience with these. I can't have window units in my apartment due to the lease, and its probably liability risk. So far I like it pretty well. It cools down my 12x15 (+2 large closets) bedroom in minutes instead of hours. I took it out of the box to try out and I had it pretty much fully installed before I knew it. So setup is easy. It cools the room which is pretty much what I wanted it to do. My room does smell like a hotel now. I was worried about noise from the outside, but even with the unit off outside noise is the same. With the unit on, I hear less outside noise. Its quiet enough I could sleep with it on easily. I did wake up with the power flickered during a storm because it beeps and goes through a cycle. The issue that could have made it better is: this unit only has the hot exhaust to the outside. Any air flowing over the hose is going to get warmed up and defeat your cooling. Nothing you can do about that. The unit also pulls air from in the room to blow outside. That means you are pulling hot air in from other rooms or cracks. I think this unit would be much more efficient if it had both an air intake and exhaust. Because if ambient temp is more than 20-25 of your set point, it gets harder and harder to reach your setmpoint. You are drawing in to much hot air that gets mixed with your cool air. It also makes the unit run almost constantly. I was hoping to see a drop in my electric bill because I was only cooling 1 bedroom instead of my 700 sqft apartment. So far its about the same. But I think I have this unit set to much cooler than my apartment AC ever was, not that it would be able to reach the lower temp half the summer. I think I also have been running my electronics more since I'm more comfortable sitting in front of them. Basically, I use them more because the room doesn't heat up to uncomfortable temps when they are on. So to sum up: I am more comfortable but I'm not saving money with this unit.

Rated 1 out of 5 by from PIECE OF JUNK I have used this unit maybe three times last summer. Today I turned it on and it isn't cooling. I am two months out of warranty. ...Enough said!

Rated 4 out of 5 by from Great product for the money We've had this portable air conditioner for about six months. It works great! Cools 25 x 25 room really well in 90 to 100 degrees weather. This room used to be a sun room, has windows all around it and has no insulation so it takes a lot to cool it down. It is a little noisy but cools the room well.

Hi my nephew threw some coins in the ac. Everything still works.  Is it OK?

Asked by: tracie13
The fact that the LG 12,000 BTU Portable Air Conditioner with remote, Model # LP1213GXR is still working affirms that it is okay, however, if those coins move and get caught up into the inner workings of the unit like the fans, they could cause some damage so it would behoove you to get them out sooner rather than later...^IFV

My filter smells moldy. How can I clean it or buy a new one?

Asked by: Mark b
The Air Filter in your LG 12,000 BTU Portable Air Conditioner with remote, Model # LP1213GXR can be pulled out by its handle and cleaned with a vacuum cleaner if its lightly soiled. If the filter is heavily soiled, it can be washed in warm water using a mild detergent. Do not use harsh cleaners or very hot water. Do not wash in a dishwasher. Make sure the filter is completely dry before putting it back into the air conditioner. The filter should be cleaned every two weeks; depending on indoor air quality, more frequent cleaning may be needed. This unit also has an Auto Clean feature that is only selectable from the remote control that you should be using to remove moisture from the heat exchange coils. This helps prevent the formation of mildew and odors...^IFV

We empty of the water when it says FL and it will reset itself but it goes off again within an hour. Although it's humid, it been more humid before and I don't think that's causing this to happen. Why does it keep saying FL when we just emptied it? 

Asked by: Kt12
We regret the trouble you have experienced with this air conditioner. If the unit resets the FL message, operates normally, and actually has moisture in the tank when the FL code appears, then it would seem that all is operating properly, and that the unit is actually drawing enough moisture to fill the tank. If this does not seem to be the case, then the unit may require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at

Water is spitting out the top. Just drained and all filters cleaned. Randomly started happening. There's water trapped in the top part of the unit where the fan is, very very loud water noise. 

Asked by: Mf11qw
Depending on how long you have had the LG 12,000 BTU Portable Air Conditioner with remote, Model # LP1213GXR and how it is stored during its' off season, what happens is that dust, dirt and debris tend to accumulate on the evaporator and condenser coils. There is a lot of wetness within the Air Conditioner that all that dust and dirt gets caught up in and overtime, it starts to accumulate and that is when it starts spitting water out through the air discharge vent in front. You should have the unit serviced by an authorized service center for a cleaning for the coils. The accumulation of dirt reduces the unit's cooling performance...^IFV

What is wrong with the exhaust?

The air conditioner was operating normally when all of a sudden the exhaust fan started making a loud rattling noise. Any easy way to fix this?
Asked by: BHubbard
We regret the trouble you have experienced with this air conditioner. If turning the machine off and then back on does not resolve the matter, then the unit may require service.

Can you attach a hose to drain?

Instead of using the small plug on the back that is too low to fit anything more than a cookie rack under.Is it possible to attach a hose to the unit?
Asked by: unknown1
We appreciate your interest in this Portable Air Conditioner. This drain port on the bottom portion of the back of the cabinet is the only one designed to remove water from the lower collection pan. This port is not designed for use with a drain tube, and should only be used when the unit is powered down and unplugged, according to the instructions in the owner’s manual.

Unit was previously owned but not used so no warranty. The air has suddenly become not as cold as it should be. The filters are clean and nothing is clogged

Asked by: Mf11
The LG 12,000 BTU Portable Air Conditioner with remote, Model # LP1213GXR has a Limited Warranty of 1 Year Parts and Labor from date of purchase and you would need a bill of sale or receipt or some proof of purchase to establish that the unit is within warranty. You can troubleshoot the unit by turning the fan to it's highest fan speed setting and turning the thermostat to its' lowest setting and see if the unit is blowing cold air. If not it probably needs a repair service. Depending on how long you have had the unit, if the unit has never been serviced to have the evaporator and condenser coils cleaned, it is quite possible that the dirt, dust and debris have accumulated on them and are clogging those which is affecting the unit's cooling performance. Other causes can vary from a defective fan, damaged compressor, leaking refrigerant, or bad relays...^IFV

I just bought the 12,000 BTU unit and the venting hose becomes extremely hot. Will this cause a fire? What is causing this and what can I do to

Asked by: Collyer
We appreciate your interest in this air conditioner. The venting hose is designed to take the hot, humid air from the air conditioner casing and release it through the window. As such, it is normal for this duct to get hot. It should have no trouble in withstanding the temperatures involved.
