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.

Very Good Product

Giraffemom 9/8/2019

I choose this air conditioner for a couple of reasons. I needed something large enough to cool 500 sq. feet in a west faceing house in the deep south. I also was replacing an air conditioner on a 230V system and didnt want to rewire. I have had it for three months during the heart of a very hot summer. It has done an excellent job of cooling. It is Energy Star complient and getting my first bill after a full month of use was a pleasent surprise. It came up short of five stars for two reasons. One its noisy. You can expect that from large air conditioners and after a month of constant use it quietened noticeably. Either that or I got used to it. Second it is BIG and heavy. I live in an old house and my window sash wasnt at all happy trying to support that much weight. I strongly suggest extra support unless you have really strong windows. All things considered expecially cooling and energy use I highly recommend this product.

Good unit

HDMWHO 8/14/2019

So far this air conditioner has functioned very well and I consider it to be slightly better than the previous unit which was also a LG product. The new unit has slightly higher noise and vibration levels but it is also slightly larger and hopefully it will have the same long reliable life span of the previous LG window unit it has replaced. Sadly the climate controls and cooling modes are the same as the older unit it replaced and they were the source of the few irritations we had with the older LG window air conditioner unit. The energy save feature of sampling the air by starting the fan is a source of noise especially at night and in the case of our partially underground house it actually uses more energy than the air conditioners with inferior thermostat designs that do not periodically force air over the temperature sensor. I have no doubt your periodic forced air sampling works well in a standard home but our partially underground home will often go hours even on the hottest days before the unit actually needs to turn on the compressors and cool. The constant cycling to test the air simply waste energy and worse yet adds unneeded noise to our home especially at night. As mentioned above the controls and operation modes on this LW1816ER are almost exactly the same as the older LG units controls and they have the same problem. You really need to add a few more options to the energy saver mode such as giving the user some way to widen the time intervals between the unit forcing air over it temperature sensor.

LG 18000 BTU window air conditioner

rob1951 4/22/2019

I have had this 18000BTU AC for 9 days. It cools as good as my last LG 18000 AC which is great. The only complaint I have is the compressor on the new one is very loud it interferes with the TV and conversations. The old one you could barely hear the compressor running. The old LG 18000 BTU AC lasted 4 yrs. till the compressor quit cycling and stayed on continuely. You had to unplug the AC to cut the compressor off. Plug it back in the compressor would come back on. It still through snow balls at you. I have had many different brand ACs over the past 40 yrs. LG has the highest air flow and gets colder than all I have owned. Also the old one used the least amount of electricity of them all. Hopefully the new one will be the same.
