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.

Robert M F 8/28/2023

I bought this air conditioner on August 9th. It is so much quieter than my old one and it keeps my house cool. I run it on the energy saver mode most of the time so it cycles on and off periodically and I am sure that it will save me money on my electric bill.

Best Air Conditioner I ever owned

EdWit1971 7/7/2023

I reserve 5-star for perfection. I gave 4-stars because its very close. I wanted the WiFi interactive model and had to buy off Amazon to get it. Delivery was perfect. Product is perfect out of the box. Its 12000 BTU and keeps my small 2-bedroom Apartment cold all by itself. However the Thermometer is attached to the unit and it thinks its colder than it really is and it shuts off the compressor when in reality the rest of the room is like 4 or 5 degrees Fahrenheit warmer. This is problematic. The Thermometer should have had options for a remote across the room one or at least one that extended out of the machine with a long cord for me to place it further away. But other than that its great. My model even has an App I control it from my phone and it runs a Diagnostic to check all kinds of things internally and tell me if all the components and coolant levels are fine.

Delivers the Goods on all Features

Claudanne 5/18/2023

I am so glad I bought this LG Thin q 12000 BTU window unit. It delivers on all promises. It is actually quiet. It cools more than the recommended square footage. It was easy to install. Everything needed to make installation efficient was in the carton. The filter is easy to access. The remote is effective at 30 feet. Thank you LG for making an excellent product.

Rollie58 11/29/2022

I bought this in late July when I really needed it. Got it installed in early Aug. 2022 and it worked great. Temps cooled off so I turned the unit off. Temps went back up so I tried to turn the unit back on. I tried everything I could do but the unit would NOT TURN ON AGAIN. Called LG help line Oct/22/2022 and Im still waiting on a service call 11/29/2022.

Terrific machine far better than expensive priors

LarryInBrookline 10/6/2022

Im the guy who always tends to spend top dollar on things. This is my second LG replacing units that cost almost twice as much think German for Fred. Much much quieter flawless operation feels solid. Im pretty stunned at the quality/cost ratio here. This is my go-to brand now.
