This post outlines how we determine air conditioner size to best fit our customer’s needs. The right air conditioner helps you cool a room efficiently. An undersized unit won’t cool adequately while one too large will not remove enough humidity, leaving the air feeling damp. The first thing we ask you as our customer is “How big a space are you trying to cool?” so we can determine what size AC unit will best fit your needs.
Below is how much you can expect a typical window air conditioner unit will cool in total square footage.
• 150 to 350 sq ft: look for a 5,000- to 8,000-BTU unit
• 350 to 550 sq ft: look for an 8,000- to 12,000-BTU unit
• 550 to 1,050 sq ft: look for a 12,000- to 18,500-BTU unit
• 1,050 to 1,600 sq ft: look for an 18,500- to 25,000-BTU unit
Another question we will ask is if the room you are trying to cool receives a lot of direct sunlight, if so you may need to step up one size to cool it efficiently.
It is also important to determine the power source. Most homes are equipped to run 110 volt units but some have wiring that will support 220 volt units. Larger units often require 220 volts to operate and many homes are not wired to support 220 volt units. These units will cool a larger area but take special plugs and wiring, so we make sure the units our customers pick match the voltage output in their home.
Lastly we have to make sure that the unit will fit into the window they want to put it in. A lot of times the customer will select a large unit only to find out that the window they want it installed in is too big or small to support the AC unit.
