As much as window air conditioners may be an old type of HVAC system, they are still one of the simplest air conditioning solutions that you can rely on , and also one of the most effective. All you have to do is mount one on the window, and you\u2019ll be able to guarantee yourself a cool and comfortable living space. An example of a good quality air conditioner that you may find works pretty well for you if you have a large living space would be the LG LW1816ER 18000 BTU window air conditioner. Whether or not it could be classified as the best LG air conditioner for you will depend on your needs, but if you have a room that\u2019s not larger than 1000 square feet, it should do pretty well. Go ahead and get to the end of this review to find out more about it.\r\n\r\nWhy We Like It - LG LW1816ER\r\nThe LG LW1816ER is a perfect example of what a window air conditioner should be, and with capabilities such as 4 way deflection and 3 cooling fan speeds, it\u2019s got just the right amount of versatility to ensure that your space remains cool and well ventilated.\r\n\r\nPerformance\r\nAt 18000 BTU, the LG LW1816ER air conditioner is pretty powerful, and this is what makes it perfect for areas that are up to 1000 sq ft. The AC unit features 3 cooling and fan speeds that you can pick on to control the temperature of your space, and with 4-way air deflection, you\u2019ll also be able to control the direction of airflow. The one disadvantage that you\u2019ll have to make due with if you choose to purchase this air conditioner is the fact that it is not portable. You won\u2019t be able to move it into a different room. If you\u2019d rather have a smaller, portable unit instead, then perhaps the LG LP1419IVSM might be of interest.\r\nEnergy Efficiency\r\nIn regards to energy efficiency, you shouldn\u2019t expect to have your electricity bill run out of control with the LG LW1816ER, as it comes with features such as an energy saver mode, and a programmable 24-Hour On\/Off timer that you can use to automatically control when it should run and when it shouldn\u2019t. The LG air conditioner isn\u2019t really energy star certified, but if you\u2019re shopping for a unit that is, then maybe the LG LW1017ERSM would be more of a good pick for you.\r\nFiltration\r\nLike most air conditioners, the LG LW1816ER AC unit does feature washable filters that prevent any harmful air particles such as dust and pollen from getting into the filter. This is essential since it helps clean up the air, and keep your living space fresh. The air conditioner features easy access slide out filters that are pretty easy to handle, so you really shouldn\u2019t require any professional assistance in doing so yourself.\r\nDurability\r\nThe LG LW1816ER will probably serve you for a long time before it begins having any kind of problems, and if it does right after purchase, you shouldn\u2019t hesitate to contact the customer service team at LG. This is well within the bounds of the 1 year warranty that the LG air conditioner comes with, but with proper maintenance, you should expect it\u2019s lifespan to stretch well over just one year.\r\nValue\r\nJust like the LG LG LP0818WNR, this LG LW1816ER air conditioner also features a remote control to allow for convenient operation, and easy installation kit so that it doesn\u2019t take that long to get it put together. If you don\u2019t consider yourself a handy person though, it\u2019ll be best if you call a professional to install it for you.\r\nLG LW1816ER Wrap Up\r\nWith many window air conditioners in the market, it can be very difficult to figure out what the best options for you may be. The few things that you want to keep in mind that may guide you into landing on the right choice include energy efficiency, cooler coverage, and cooling power.
