If you are looking for an 18000 BTU portable air conditioner, however, you will pay substantially more, with some units going for $3,600. Also, Consumer Reports warns consumers to stay away from portable ac units, citing their weak cooling capability and high price.
If you are in the market for an 18000 BTU air conditioner, here are your best bets.
1) LG 18000 BTU Air Conditioner LW1812ERS (cost $479)
The LG window air conditioner cools rooms up to 1000 square feet. This model comes with a number of energy-saving features, including an energy-saver function and a 24-hour programmable timer. This will help you save on your monthly electricity bills.
The LG also comes with a remote and special anti-corrosion coating on the unit itself. It also has three fan speeds and a nifty auto cool feature so that you can set it and forget it.
There are a couple of things that you should know about this unit before you purchase. First off, it is heavy. This baby weights in at over 100 pounds. Make sure you have a few people to help you get it into the window.
