It appears to all of us that the bigger we buy the better we get but when it comes to choosing an air conditioner this idea does not apply. To give you an idea, an 8000 BTU air conditioner is too much powerful for a 200 sq ft room and most of the energy is wasted. But for a room of 450 sq ft in size this is quite small.

When you think of buying a portable air conditioner there are many factors that you have to keep in mind. There is one factor which the customers generally ignore and that is the BTU or the British Thermal Unit which is simply a measure of energy. The higher the BTU the more powerful will be the AC. The BTU gives us the ACs power as well as its cooling capacity.

Some of the portable air conditioners have their BTU of about 5,000 and generally ranges up to 30000. We actually get home appliances proportionate to our needs, and in exactly the same way we should do for the cooling unit as well. So if we have a space with size ranging from 300 to 350 sq ft then the 8000 BTU air conditioner will be perfect for it.

Various fine-looking and functional air conditioning units are available nowadays that suit a person’s lifestyle. For small areas a model like the AF8000E Portable AC is favorable as it has a cooling capacity of 8000 BTU which can even cover an area of 300 square feet.

The Frigidaire 8000 Btu Air Conditioner is another model which has an energy star rated cooling system. This saves a lot of energy and at the same time keeps the room cool even in the scorching heat of the summer. This super cool AC comes with remote control and is favorably priced between $209 to $289.

Another very good Energy Star Rated 8000 btu air conditioner is from GE - the AEM08FM window model. This is also an energy saver AC with 8000 BTU, making it much easier to save on electric bills. An electronic thermostat takes care of the temperature regulation.

The AC should be kept away from direct sunlight. If your room gets a lot of exposure to sunlight most of the time then you need a more powerful unit.

Keep your room insulated to get the maximum benefit. Look for small gaps and places from where the air can escape. You may wonder why a large cooling unit is not cooling your room properly and that is because the truth of the matter is that your room is not leak proof.
