How do I know how many Btu's I need when choosing my Air Conditioner?
This is one of the most frequent questions we are asked but fortunately it is also one of the more simpler questions to answer!
Measure the height x width x depth of your room in feet to get your volume. (ie 12ft x 12ft x 8ft = 1152 ft3).
Now, take that figure and multiply it by 5. (ie 1152ft x 5 = 5760). In this example 5760 is the minimum BTU rating you should consider for your air conditioner.
Note: You should always try to opt for a unit with more BTU's than you think you need, this way the room will be cooled more quickly using less electricity. Also the unit will stand more chance of cooling your room on the really hot days.
