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.

Excellent air conditioner. Five stars.

Jack Mevorach 12/12/2020

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.

Purchase history

zane78 5/5/2020

I originally purchased this air conditioner in 2016 and had it professionally installed in a pre-existing wall-sleeve. I got 3.5 years of cooling from it until the compressor failed. I followed-up by purchasing it again in 4/2020. That unit had a broken motor. Amazon refunded me for the purchase. I bought the same model again from Lowes. That one had a broken fan. Another refund. Ive decided to move on to another brand.

Matlacha 7/10/2019

I already have a LG 18kBTU in a vacation home on the water on the Gulf but wanted to add a separate unit for the bedroom. This does the job. If it is as reliable as my other one it will last a long time. These units are a little noisy though.

Replaced a 35 year old Carrier unit. Much better performance and quieter as well. Love the remote as the old unit had only two settings: on or off. I noticed the electric bill has gone down noticeably too.
