Choosing the best air conditioner suited to your needs is easy! Here are the various elements to consider:
On ACBrands, you can choose between portable air conditioners and window air conditioners. Portable air conditioners are exactly what they look like: you can easily move them from one place to another (they are mounted on wheels). This allows you to change room everytime you want.
Window air conditioners are fitted to a window opening. You have a few work to do by yourself, but don't be afraid: it is very easy. The units come with full instructions and all the needed accessories: mounting brackets, extensions to fill spaces, etc. In practice, any unit may be fitted to nearly any window of a larger size.
The cooling power of an air conditioner is expressed in BTU (British Thermal Units). It basically represents the amount of cooling the device can produce per unit of time. This is similar to heating power, except that you produce cool air instead of heat.
Here is the average cooling power you need according to your room size (data from Energy Star):
|Area To Be Cooled (square feet)
||Capacity Needed (BTUs per hour)
|250 up to 300
|300 up to 350
|350 up to 400
|400 up to 450
|450 up to 550
|550 up to 700
An air conditioner is actually a "heat pump": it "pumps" heat from one place to another. This is why portable air conditioners are fitted with a hose: it is necessary to evacuate the heat that has been pumped from the place you want to cool.
Some models take advantage of this and can also work in reverse, providing heat instead of cold air, by pumping heat from the outside (instead of rejecting heat to the outside). The big advantage with respect to a traditional electric heater is that it is much more energy-efficient. This is because the device doesn't have to actually produce the heat itself, but only to "pump" it from the outside (even if it's cold outside, there is still much thermal energy available).
Many models exist in both versions (reversible or not), and the added cost for the reversible option is usually quite low - this is generally a good deal, and you will appreciate this functionality when winter comes in!
