LG Window AC 12,000 BTU - Great for large rooms

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. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances 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 appliances 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.

Great Air Conditioner

Bobmo53 1/28/2025

I bought this model because my old a/c started to break down after about 20 years. It cools the hot room quickly and quietly. My old unit was12000 but. This 10000 was just as good. I recommend this unit to everyone

LASTED ONE SUMMER NO HELP FROM LG

WyattB 9/30/2024

I putchased this model last summer $416.20 with tax third LG appliance. Quit cooling 58 days out of warranty because of a refrigerant leak or failing compressor. Cost prohibitive to repair due to parts cost. ZERO ASSISTANCE FROM LG. Think twice before purchasing anything made by LG especially an air conditioner or refrigerator.

Dont Worry Be Happy

Dan Loran 7/22/2024

Purchased this very nice new LG Air Conditioner a month ago and we are very pleased with it We run two Window Units summertime in NJ and its been so terribly hot and humid this season. The LG we purchased 5 years ago is still working superbly well - but the other different manufacturer model wed bought only a few years ago had completely failed twice on us. First one was replaced under warranty a year ago and recently broke-down again. This time we decided to Go with LG similar to our other well working model. So we are now running two LGs in the house
