Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

OMG

Neetsie 7/7/2021

I bought this unit over a month ago. Just before the 2nd heat wave. My old unit conked out at the end of last season. I am 78 years old and I needed a unit that I did not need a degree to operate. I love it.

Pleased so far

namhel 6/23/2021

I had this unit installed about 6 weeks ago just in time for some of the hottest temperatures of the year so far. The unit performed like a champ keeping us cool and comfortable in a space of approximately 400 sq. ft. So far I have tried the Cool Mode Energy Saver Mode and the Dry Mode. All work as advertised. The reason I gave this 4 stars instead of 5 is that I was expecting the unit to be a little quieter. Its not so noisy as to keep me awake at night but I would not describe it as quiet. All in all I am pleased so far. We used a through the wall LG sleeve to install the unit. Im not sure how we would have gotten the AC unit installed if we had followed the directions verbatim. The unit kept dislodging the foam that was supposed to seal the gaps. It worked better to insert the unit in the sleeve and then stuff the foam in the gaps to seal it up.

Too many stops

Guzi 6/13/2021

The A/C cools quickly but the thing is that when it reaches the set temperature it doesnt stay quite for a reasonable period. It restarts stops too often which is disturbing annoying.

It cools our AZ room fast

Virginia in AZ 6/4/2021

I purchased this unit to replace an old unit that was about 40 years old. This LG is perfect. It puts out cold for sure. We purchased the sleeve and coil cover extra. We had to make sure the unit tipped away from the front. Some shims did the job. We got it in place finished off and sealed everything. We plugged it in and yee Haa. It handles 500 sq ft easily. We had it shipped to store to avoid any issues. No problems there. It is a nice ac that has more than enough giddy up for our needs. Thank you LG

Lousy unit 6/1/2021

reliable company

Frank BZH 1/6/2021

I bought an LP air conditioner model LT1216CER for my family room to replace an old a/c unit that no longer worked. The room is 15 by 20 and the LG unit cools it down quite well and it does not make much noise unlike my last unit. I bought an LG air conditioner because a few years ago I bought an LG gas dryer and I am very happy with how it works. It is a quiet work horse. I expect the same from my LG air conditioner..

For the most part the compressor is not heard. Only the fan is heard. The sounds of the unit are pleasant and soothing. The unit blows powerfully and quite cool.

Gulfportjude 12/11/2020

After initial delivery was rejected due to damaged box packaging a subsequent intact package was delivered and the AC wall unit installed. It has been operating satisfactorily ever since. I like the light that lets you know when to clean the filter. Also that you can reset by simply unplugging and replugging into the power source.
