Too small? It won't cool. Too big? It's humid and inefficient. Calculate the exact BTU requirement for your space instantly.
* This is a guideline estimate. Factors like insulation quality and window type also affect load.
Many believe "bigger is better" for AC. This is false. A unit that is too large will cool the room quickly but turn off before it has removed humidity, leaving you cold but clammy. A unit too small will run forever and never reach the target temperature.
