Smallest Window Air Conditioners For Small Windows

A small window needs a small window air conditioner. The choice of which window air conditioner system to use depends upon a number of factors including window sizes and how large the room is to be cooled or heated. If your room has only small windows which aren’t enough to put a regular unit of window AC in, you need to buy a smaller unit.

Window air conditioner is the most commonly used air conditioner for single rooms such as bedrooms or living rooms. It’s ideal for those who don’t want to pay a thousand dollars for a central air conditioning system just to keep a single room cool. For this unit, you don’t have to make any slot in the wall of the room like a through-the-wall air conditioner. And if conserving floor space is important to you, then it is likely that a window air conditioner is the more suitable than a portable air conditioner. Further, a window air conditioner costs as little as a couple hundred dollars and be installed without the help of a professional.

For anyone living in a small room and don’t want to pay for an expensive air conditioning system, a window air conditioner is an easy solution. There’re many good options available on the market. They come with different BTU’s, different sizes in different prices. It’s hard to figure out which one is the best for your needs. The best window air conditioner is one that provides the right level of comfort for a given room size and as small as possible to fit any window size.

With an affordable price and an extremely good quality, this unit from Haier is one of the most popular 6000 BTU window ACs in US. Haier currently has been named one of the best wine cooler brands of 2017 in our list.

The best feature of the Haier HWR06XCR is that the unit is programmable. It’s very convenient because you can program the air conditioner to turn on about a half an hour before you I get home from work, you can walk into a room that is already comfortable and cool. This way the unit is not running all day and wasting energy cooling your home for no reason. Keeping cool is essential. But what isn’t essential, is the piling electricity bill at the end of the month.

This unit is designed for a room up to 250 square feet. It also can remove 1.6 pints of moisture per hour, less than the LG but still above average for fighting humidity (1.4). It’s small 18.5 x 12.4 x 15.3 inches so it fits in most window. The filter is very easy to remove and clean something which needs to be done at least several times throughout the cooling season.

In our test, the Haier HWR06XCR is louder than the other reviews but it’s “white noise” – white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density, white noise helps you relax and fall asleep fast. If you sleep with the white noise every night, it’d be your best friend, you can’t sleep without it.

With all the best features above, and the price is affordable, this window air conditioner unit is a great option.
